Discovering Gluten Sensitivity Through DNA Testing

Discovering Gluten Sensitivity Through DNA Testing



Gluten is a kind of natural protein that can be found in wheat, barley, rye, and other grains. It is found in many common food and drinks such as dough, pasta, cereal, beer, and even some types of medicines. Too bad for you if you love pizza and carbonara and turns out you have gluten sensitivity. Even food without naturally occurring gluten can still be contaminated if they are processed in factories that also handle grains or otter food that contains gluten. 

Gluten acts like a binder, giving food a solid bond and that “stretchy” texture. For example, a dough without gluten cannot be kneaded and hand-tossed without a gluten substitute because it can easily rip apart. While a gluten-free diet may need extra planning and paying attention to nutritional labels, it is possible and millions of people have switched to it, even those without gluten sensitivity issues because of the supposed health benefits it can give you.

What is Gluten Sensitivity?

Gluten sensitivity, also sometimes known as non-Celiac gluten sensitivity (NCGS) or gluten intolerance, is when you get sick after eating food or drinks that contain gluten. Symptoms of gluten sensitivity may range from occasionally passing gas to locking yourself up in the toilet for hours. These symptoms can manifest anytime from after eating the gluten-containing food up to several days. Signs of gluten sensitivity may include:


  • Gastrointestinal issues such as abdominal pain, diarrhea, and irritable bowel syndrome

  • Bloating and flatulence

  • Unexpected fatigue or brain fog

  • Nausea and vomiting

  • Joint and muscle pain

  • Skin rashes or hives

Genetics and Gluten Sensitivity

Gluten sensitivity can be influenced by your DNA. Since gluten sensitivity is highly related to food allergies, we have analyzed genetic variants that are linked with allergenic reactions including the varied HLA and MYO9B genes.

Benefits of DNA Testing for Gluten Sensitivity

Doing genetic testing with LifeDNA for personalized nutrition can tell you what your gluten needs (or lack thereof) and you can start from there.  A comprehensive nutritional genetic testing on your gluten sensitivities may help with managing your symptoms, identifying potential gluten triggers and avoiding them, as well as reducing your risk of adverse reactions to gluten-containing food and beverages.


LifeDNA can provide a full and comprehensive Nutritional Report that includes gluten sensitivities, food allergies, vitamin deficiencies, and other health factors based on your personalized nutrition test.


What causes gluten sensitivity?


Gluten sensitivity is not to be confused with gluten allergy. Simply speaking, food sensitivities or intolerances affect the digestive system while food allergies are triggered by the immune system. Gluten sensitivity is more common than you might think and affects people of all ages. Some people are born with gluten sensitivity while others develop them with age. 

Diagnosing Gluten Sensitivity


To diagnose gluten sensitivity, your primary care physician may ask you to go on a gluten-free diet for a certain period of time, usually for more or less six weeks to rule out Celiac disease or wheat allergies. They might also perform blood tests and skin tests. The former is to see how your immune system will react to wheat proteins and the former is a prick test of wheat protein on an area of your skin for adverse reactions.

Celiac Disease vs. Gluten Sensitivity

Gluten sensitivity vs. Celiac disease has long been lumped together because of the similar symptoms they cause. The two, however, are two different conditions. Celiac disease is an autoimmune condition caused by an abnormal gene wherein the body’s response to gluten is to treat it as if it were an invading virus. With this condition, your tissues eat at your gut (small intestines) whenever you ingest gluten, causing much inflammation and damage to your digestive tract. 


While gluten sensitivity can become uncomfortable and sometimes downright painful, it is generally considered a less serious condition compared to Celiac disease. Gluten sensitivity also isn’t caused by abnormal genes, although they can be genetic. 

Can gluten sensitivity cause hair loss?


Gluten doesn’t directly cause hair loss but there are studies that show gluten can influence hair loss. Celiac disease has hair loss listed as a symptom and because gluten is related to this condition, gluten might aggravate the hair loss situation, especially if you have been diagnosed with Celiac disease. 

Can gluten sensitivity cause acne?


While gluten’s relation to Celiac disease can be linked to several skin conditions, there is no scientific evidence that gluten can cause acne. No studies have shown that gluten triggers acne either so you might want to go easy on the spot treatment after eating a burger for dinner. 


Plus, did you know that acne can also be influenced by your DNA? Some people are more likely to develop severe acne as compared to others.

The Role of Genetics in Lactose Intolerance

The Role of Genetics in Lactose Intolerance


How many people do you know can’t drink milk or anything with dairy in it because it “doesn’t agree with them”? While the effects of lactose may vary from person to person, they can all agree that lactose intolerance can be uncomfortable, if not downright painful. Nowadays, nutritional genetic testing lets you know if your DNA is more likely to make you lactose intolerant.

What is Lactose Tolerance?

Lactose intolerance is a condition in which the body is unable to fully digest lactose, a sugar found in milk and milk byproducts. This is due to the lack of an enzyme called lactase in the small intestine. As a result of this malabsorption, consuming dairy may cause bloating, gassiness, and diarrhea.


Some people who are lactose intolerant can still consume dairy products in small amounts while others need to completely eliminate lactose from their diet. It all depends on how badly the symptoms manifest for an individual and what their healthcare provider says about it.

Some tests can be done to determine if you are lactose intolerant. The hydrogen breath test and the lactose intolerance test are two of the most common methods used by healthcare professionals to determine if an individual has this condition. 


The hydrogen breath test is done by making an individual drink a liquid with plenty of lactose and then measuring the hydrogen levels in their breath afterward. Too much hydrogen means you are lactose intolerant. 


The lactose intolerance test makes you drink a liquid with high levels of lactose and then your blood will be drawn two hours later to see if glucose levels rose. If glucose remains the same, this means your body is not digesting the lactose in the liquid and you are intolerant.

Top 7 FAQs About Lactose Intolerance

Today, we’re answering your most frequently asked questions about lactose intolerance. 

Does genetics affect lactose intolerance?

Yes, lactose intolerance can be influenced by your DNA. For people who consume dairy with genetic lactose sensitivity, there may be excess gas, pain, and other digestive problems. One of the genes we analyze for your lactose tolerance is your MCM6 gene. Discover your genetic likelihood of lactose intolerance today based on DNA with our LifeDNA Nutrition Report.


Who is most likely to have lactose intolerance?


While children and younger adults are less likely to be lactose intolerant, they can still develop the condition at a later age. Some health experts even view lactose intolerance as a natural condition of the human body rather than a serious condition that needs to be treated. Apart from age, ethnic background may also be a factor for individuals with lactose intolerance. 

How long does lactose intolerance last?


Symptoms of lactose intolerance usually manifest anytime between 30 minutes to 2 hours after an individual has consumed dairy. They can last for up to 48 hours depending on how much dairy was consumed.

Does lactose intolerance cause constipation?

Apart from the typical symptoms of bloating, flatulence, diarrhea, and abdominal pain, a good number of cases of lactose intolerance also has constipation as a symptom. This particular symptom can also be as uncomfortable and painful as diarrhea.

What happens if you ignore lactose intolerance?


Lactose intolerance is usually harmless if the symptoms that manifest are only mild to moderate. Some people have symptoms that are mild enough to be ignored, thus, they continue to consume dairy in moderate amounts. Lactose symptoms can vary in severity but if you suspect that you have severe digestive problems, contact your primary care physician immediately.

Can you reverse lactose intolerance?


If lactose intolerance is caused by an underlying condition, getting treatment for the pre-existing disease might help alleviate the symptoms of lactose intolerance, if not completely restore the body’s ability to digest the enzyme. However, if lactose intolerance is caused by the lack of lactase, there is not much an individual can do except manage their symptoms and avoid dairy.

Does lactose intolerance get worse with age?


It is not uncommon for people to suddenly develop lactose intolerance. This condition can either be primary and congenital or secondary and developmental. The former is hereditary and passed down via genetics while the latter is caused by decreased lactase in the body. Secondary lactose intolerance can occur at any age but is more likely to occur at a later age.

Can stress cause lactose intolerance?

Researchers have long found a link between gastric and digestive problems with mental and psychological issues. According to these experts, stomach problems may have little to do with what an individual has consumed and more with anxiety, stress, depression, and other psychological conditions.

Using the latest research for the most accurate results, LifeDNA’s  Nutrition Report will tell you about your body’s response to certain foods based on DNA. This includes your potential food sensitivities, allergies, and intolerances.

How to Manage Lactose Intolerance

A lactose-free diet is not as restrictive as it sounds. Fruits, vegetables, meat, poultry, seafood, soy products, whole grains, nuts, and healthy fats can still be fully enjoyed by lactose-intolerant individuals. Just a precaution, be sure to consult with your doctor first before making any major changes in your diet.


Additionally, be extra careful when consuming dairy and dairy-based products. Try the elimination diet and slowly reintroduce dairy products in small amounts into your diet and see how much is too much and what moderate means. You can also find dairy alternatives such as plant-based products and byproducts.

The Role of Genetics in Vitamin B12 Deficiency


The Role of Genetics in Vitamin B12 Deficiency

Ancestry (2)


If you are a health buff, or even just someone who casually watches out for their vitamin and mineral intake, you would know that Vitamin B is essential for your body. There is not only one Vitamin B but eight types of Vitamin Bs. These B-group vitamins are water-soluble vitamins that are necessary for the body to complete certain metabolic processes.

How Important is Vitamin B12 to Your Overall Health?

The human body does not make Vitamin B12 on its own. You have to either get it from certain foods or from supplements. There is a certain amount of Vitamin B12 that is recommended daily for the human body depending on factors such as age, body weight, and diet. 


Luckily, plenty of food commonly contains Vitamins B1, B6, B9, B12, and others. Some examples of food with Vitamin B are eggs, red meat, soy products, nuts and seeds, and shellfish. Some Vitamin B12 vegetables and fruits include dark, leafy greens, potatoes, mushrooms, bananas, apples, and berries.


Does Genetics Affect Vitamin B Levels?

The deficiency of Vitamin B12 can be linked to genetic factors, as well as lifestyle, dietary, environmental, and other intrinsic factors. While these studies are still premature in their scientific evidence, technological advancement in DNA testing for vitamin deficiency has greatly helped those affected by decreasing or deficient Vitamin B levels.

Want to know if you have a higher risk of Vitamin B-12 deficiency based on your DNA? Find out now with LifeDNA’s Vitamins Report – available for free when you get your Nutrition Report today. 

Does Vitamin B12 give you energy?

The B-group vitamins in general help your body convert the food you eat into glucose, which is then converted into energy for you to go about your daily tasks. Vitamin B12 is said to aid in a number of processes including the production of red blood cells, the production of elements for DNA to be formed, and the overall health of the nervous system. 

What are Vitamin B12 benefits for hair?


Vitamin B12 deficiency is often linked to hair loss and thinning of hair as symptoms of anemia. While Vitamin B12 does not prevent hair problems nor solve them, they are known to help in the production of red blood cells, which then carry oxygen to the hair follicles for hair health. A deficiency in Vitamin B12 may increase your likelihood of 

LifeDNA’s Genetic Testing for Vitamin Deficiency

What is too much Vitamin B12?

Your body’s B12 levels are essential for your overall health and well-being. According to the NIH, the recommended daily dose of Vitamin B12 for adults is 2.4 mcg but consuming more than that is your safest bet, the body absorbs what it needs and the rest gets secreted via urine because B vitamins are water-soluble.


The tolerable upper intake level for those suffering from a B12 deficiency is up to 1000 mcg per day. Discover your Vitamins B Levels today based on your DNA with LifeDNA’s most powerful nutrition and vitamin reports.

How to Manage Vitamin B Deficiency

Some people find it easy to manage their Vitamin B deficiency by making dietary and lifestyle changes. Others turn to B12 supplements after talking to their primary care physician. The bottom line is, Vitamin B12 deficiency is manageable if it is detected and addressed early on.

How To Identify Potential Deficiencies Using DNA


How To Identify Potential Nutritional Deficiencies and Tailor Your Supplement Regimen Using DNA

In a fast-paced world, everything changes, including food. Whereas before, food was a source of strength and energy for people to go about their daily tasks, nowadays, food is also a luxury and sometimes even an experience. 


The way that food is prepared has changed so much within the recent decades, and with that, its nutritional value. 

For many, a nice, hearty, and delicious meal cooked at home has been replaced with everyday cheap, accessible, and delicious fast food. 


What is Nutritional Deficiency?

As a result of this, health concerns have also been on the rise. Food is, after all, everyone’s first source of vitamins and minerals. One of the major health concerns that have been growing recently is nutrient deficiency. Fast food and other types of commercial food have been directly linked to the rise in nutrition deficiencies for many. 


By definition, nutritional deficiency is when an individual’s body does not get or is unable to absorb the proper amount of nutrients such as vitamins and minerals. People who have nutritional deficiencies may need supplements for their bodies to function properly. Nutritional deficiency in itself is not a disease but it can be the cause of other complications down the road such as anemia, which has many types depending on what caused the condition. 


Is Nutritional Deficiency Influenced by DNA?

While genetics is known to pass down food intolerances and allergies, recent research has shown that genetics also play a role in nutritional deficiencies. Thanks to technological advances, these factors can now be traced via DNA sampling and analyses. LifeDNA is one of the most premium personalized wellness companies that offer genetic testing and analysis for nutritional needs and a complete and comprehensive report for individuals who want to know more about their potential foods response and sentivities and whether or not they have deficiencies.

How to Tell if You’re Deficient in Vitamins


Nutritional deficiency can manifest in many different ways depending on which particular vitamin or mineral the body is not getting enough of. There are many telltale signs of deficiency but they sometimes blur altogether that it is difficult to pinpoint what particular nutrient your body needs. Blood tests are the most efficient but your primary care physician might recommend other tests just to rule out other causes for your symptoms. 


There are some common sympoms that you might want to watch out for if they continue to persist. Some of them may or may not include severe hair loss, extreme and chronic fatigue, irregular heartbeat (tachycardia), muscle weakness, slow healing of wounds, frequent infections, etc. These symptoms may be due to other underlying health conditions so talking to your physician is always your best bet.

What Vitamin Deficiencies Cause Tingling in the Hands and Feet?

Vitamin B12 deficiency can cause a “pins and needles” sensation in both the hands and feet. They may vary in intensity and can come and go. This is because B-12 plays a crucial role in the nervous system, the lack or absence of it can increase the risk of developing nerve conduction problems and even nerve damage if not treated properly and immediately. Can low B12 cause dizziness? The answer is yes and this can turn chronic (vertigo) if not addressed with supplements. 


Do you have a higher likelihood of Vitamin B-12 deficiency based on DNA? Find out now with Free Vitamins Report – available when you get your Nutrition Report today. 



What Vitamin Deficiency Causes Muscle Cramps?

Muscle cramps and pain are most common for people with Vitamin D deficiency. The body cannot produce Vitamin D on its own; the main source is the sun. The whole process is complex but, when the sunlight hits the skin, the body can convert it into Vitamin D. During the winter or seasons when the sun is scarce, people are at a higher risk of developing Vitamin D deficiency. 


Supplements come in handy and food rich in Vitamin D such as salmon, cod, tuna, beef liver, and dairy products fortified with Vitamin D. Can low Vitamin D cause shortness of breath? Studies show that being low on the vitamin has to cause a myriad of respiratory problems including shortness of breath.


Discover your Vitamins D Levels today based on your DNA with LifeDNA’s most powerful nutrition and vitamins reports.

Other Common Types of Nutritional Deficiencies


Apart from B-12 and D, there are other common types of nutrient deficiency. Lack of Calcium, Iron, Iodine, Zinc, and Magnesium are a few examples of these. While they may not be life-threatening when they manifest, nutritional deficiencies can be a source of discomfort and even pain. The good news is that reversing these deficiencies can be reversed, managed, and treated with diet and lifestyle changes, and, of course, with the help of supplements.

The Genetics of Food Sensitivities: How LifeDNA’s DNA Analysis Can Help You Identify and Manage Adverse Reactions to Certain Foods

The Genetics of Food Sensitivities: How LifeDNA’s DNA Analysis Can Help You Identify and Manage Adverse Reactions to Certain Foods

How many times have you eaten something, thinking it was good food not to be wasted, and ended up paying for it hours later in the bathroom? Your body’s reaction might not be all that alarming apart from a bit of gas, belching, bloating, or maybe moderate irritable bowel syndrome (IBS). Still, it can get pretty uncomfortable, if not downright painful. 


Knowing what food triggers these reactions in your body will help in managing the symptoms or even eradicate them. Apart from the try-it-and-test-it method of ruling out which food to avoid or eat more of (others consider this is the best test for food sensitivities while others think it is unnecessary if not scientifically tested), a food sensitivity test can be done via DNA analysis. LifeDNA offers a comprehensive DNA nutrition analysis for individuals who want to start optimizing their diet and wellness.

What is Food Sensitivity?

Food sensitivity is also sometimes called food intolerance. Some experts separate their definitions but many lump them together. Food sensitivity is the body’s reaction to food that cannot be digested or digested at a much slower rate than usual by the digestive system. This might be due to your body’s lack of enzymes to digest a certain food. Simply put, when you are sensitive to a certain food, symptoms can arise – symptoms that can make you uneasy, uncomfortable, and even cause pain. 


Some of the most common food sensitivities symptoms can include excessive gas, bloating, diarrhea, constipation, nausea, vomiting, and stomach cramps. Not to be confused with food allergies, almost always, the symptoms are digestive-related and that’s how many identify food sensitivities. Food allergies may vary in severity and affect the immune system, which when left untreated, can become a serious health issue and even life-threatening. 

Can My Genetics Affect Food Sensitivity?

Over the years, there have been multiple studies that suggest DNA may play a role in our food allergies and sensitivities. This only suggests that looking into your  DNA can provide a wide array of information about an individual’s well-being.   


Using LifeDNA’s personalized nutrition analysis, your nutritional needs, food sensitivities, your body’s needs for unique vitamins and minerals, as well as its ability to digest lactose and tolerate gluten can be revealed.   Your DNA can greatly help you achieve optimal nutrition.

How Can LifeDNA’s Genetic Testing Help with Food Sensitivity?

LifeDNA’s genetic testing can generate personalized nutrition tests for individuals. Our popular nutrition DNA analysis can allow you to use your existing DNA test results to discover what foods would work best for your unique body based on DNA.

Why do I have so many food sensitivities?

An individual can have multiple food sensitivities. If this is the case for you, no need to panic yet as many food sensitivities can be treated or managed. One of the most common food intolerance is lactose intolerance and it can often be managed by taking Lactaid pills or other kinds of medicine to help relieve you of symptoms. 

How Can I Manage My Food Sensitivities?

Food sensitivity may vary in severity from person to person. Managing them usually entails taking a closer look at your diet, changes in lifestyle, and sometimes taking medications that can help relieve symptoms and discomfort. It is important to consult first with your primary care physician when going on diets that may affect your overall health and well-being. Food journaling may also help you keep track of what food triggers your intolerance and what keeps them at bay. 


Understanding and managing food sensitivities can help prevent you from potentially developing more serious health-related problems down the road.

Are You More Likely To Binge Eat Based On DNA?

Are You More Likely To Binge Eat Based On DNA?


People may tend to overeat from time to time. 

However, binge eating is a different matter. If you always eat a large amount of food in a brief period of time, even when you are not hungry, you’re probably binge-eating.

When you’re binge-eating. you’re also more likely to feel embarrassed or guilty about it.

Your genetics play a significant role in your diet and health, particularly your eating habits. LifeDNA has found 5 important genes that can influence your likelihood of binge-eating. 

What is considered binge-eating?

Binge-eating and overeating both include mindless activity. You eat excessively without considering why. 

However, there are significant differences.

Here are some examples of overeating:

  • Enjoying multiple desserts after dinner
  • Consuming an entire bag of popcorn while watching a movie

Here are some examples of binge-eating:

  • Consuming two or three burgers even when you’re already stuffed.  
  • Eating to the point of pain.
  • Eating a whole cake in one sitting and then feeling guilty. 

Your FTO Gene & Your Eating Habits

A variety of genes influence your likelihood of binge eating. These genes have the potential to influence brain circuits that regulate hunger and mood.

One of the genes that our geneticists have looked into is your FTO gene

Your FTO gene is also linked to other traits such as:

  • Saturated Fat Metabolism 

How quickly do you metabolize saturated fats?

  • Satiety  

Trouble feeling full? Ask your DNA.

  • Appetite 

Appetite determines how much you naturally want to eat.

  • Preference for fatty foods 

The food you love to eat is heavily determined by your genetics. 

  • And weight change 

Research suggests that for some people, genes account for 25% of their predisposition to be overweight/underweight, while for others, the genetic influence is as high as 70% to 80%. 

Want to get personalized diet insights tailored to your DNA? Check out our nutrition report now

Certain genetic variants may increase your likelihood of binge eating, but other factors including your lifestyle and environment can also trigger it.

Here are some other external factors that can affect your binge eating tendencies:

Parents and families. 

If you often see your parents overeat, you’re more likely to pick up these behaviours.   The practices you acquire from the people around you may have an impact on your eating habits. 

Anxiety and Stress.

 People tend to binge eat after going through a serious, stressful situation. It is important to note that emotional eating is not always a sign of binge eating.


Depression may increase your likelihood of binge-eating. In fact, about 50% of people who tend to binge eat are also depressed. 

Excessive calorie restriction.

 An attempt to shed a few pounds might sometimes result in binge eating. This is particularly true when people try to lose weight by cutting meals or consuming too little. If they don’t attain their target weight, they may feel so bad about themselves that they overeat.

If you want to lose weight, the best DNA test will help you do that based on the way your own, individual body works. 

Final Thoughts

Binge-eating can lead to obesity, which is a risk factor for many diseases. 

That’s why it’s important to know your genetic predisposition to binge eating in order to get the right prevention management from health care professionals.

Do Weight Loss DNA Tests Actually Work?

Do Weight Loss DNA Tests Actually Work?


 If you want to lose weight, the best DNA test will help you do that based on the way your own, individual body works.

The problem with most diets is that they assume we all have the same bodies, metabolisms, and genetic potential.

While a DNA diet alone won’t help you lose weight (you’ll need to put some effort in too), research has proven that eating a diet tailored specifically to your make-up can be a powerful aid to weight loss.

Read on to find out how you can use the latest discoveries in genetic science to help you drop the pounds.

Here’s the TL;DR…

  •  We know that your genes have a big impact on how your body processes food and distributes weight
  • DNA test results can arm you with the information you need to optimize weight loss (but the effort has to come from you)
  • Most DNA testing companies just give you your test results with not much actionable information
  • For the best chance of losing weight, choose a testing company that helps you with eating plans, recipes and food guides too

How does your DNA affect weight loss?

Over the last decade, nutrigenomics has revealed a wealth of information about how DNA can impact weight loss.

We now know that there are many genes involved in how your body processes nutrients. Knowing which versions of those genes you carry can help you decide on the right diet for you.

For instance, if your overall genetic pattern suggests that your body has a higher tendency than average to store excess carbohydrates as fat, you could be better off eating more proteins and fats.

But how can a DNA test help with weight loss?

The best DNA tests today can reveal over one hundred of your genes. Many of these are involved in how your body processes the nutrients in your food.

You have inherited a mish-mash of genes from both your parents that govern how your body works.

Nutritional genomics—also known as nutrigenomics—is the science that studies the relationship between your genome (genes), what you eat and your health.

Nutrigenomics is uncovering more and more every year on how your DNA affects your weight, as well as your fitness. For instance, genetic variants impact the effect of saturated fat on your body, and the levels of hormones that regulate your appetite.

What is the best DNA test for weight loss?

Genetic testing for weight loss has huge potential to help a lot of people get to a healthy weight and stay there.

For that reason, multiple companies have sprung up to test your DNA so you can give yourself the best chance of reaching your ideal weight. But they’re all different, with their own advantages and disadvantages.

You need a DNA test that gives you actionable results: one that tells you exactly what to do, how to do it, and why.

Why are some people more sensitive to spicy food than others?


Scientists have known for a long time that chili peppers’ heat stems from a chemical called capsaicin.

The capsaicin receptor (TRPV1) in the mouth regulates the amount of pain that comes with a spicy meal.

People’s sensitivity to spicy food varies, which helps to explain why some individuals can’t stand spicy dishes while others enjoy them.

You may be more sensitive to bitter foods, for example, and that can affect your food preferences. 

You may also be more sensitive to caffeine as compared to others. In fact, some people may experience anxiety, headaches, stomach pains, or high blood pressure when they consume coffee.

Here are some other foods that your body may respond to differently depending on your DNA:

  1. Carbohydrates
  2. Saturated fats
  3. Lactose
  4. Gluten
  5. And more!

2. Spicy foods increase metabolism.

Several studies have found that spices like cumin, cinnamon, turmeric, and peppers might increase your metabolic resting rate while decreasing your appetite.

Lying down enables the acids in your stomach to run back up into your esophagus and burn the lining. As a result of the discomfort caused by heartburn, falling asleep might be difficult.
