Gluten intolerance is a common health issue nowadays. People, who are intolerant of gluten, a protein found in grains, like rye, wheat and barley, may experience severe reactions after consuming it.

It makes up nearly 80 % of the amino acids in these grains. Some of the most obvious symptoms of gluten intolerance include fatigue, gastrointestinal issues, joint pain, depression and others.

Here are some of the most common symptoms of gluten intolerance. Read and find out more about them.


Damage done by the gluten intolerance goes beyond the gastrointestinal tract. Numerous researchers have shown that the symptoms of gluten intolerance show up in nearly all systems of the body: the endocrine system, the central nervous system, the cardiovascular system, including the blood vessels and the heart, the skeletal system and the reproductive system.

1. Mouth problems

People who are intolerant to gluten usually experience aphtous stomatitis, a state characterized by canker sores and mouth ulcers. Moreover, due to malnutrition, people who suffer from gluten sensitivity find it harder to keep their teeth healthy, because they have reduced levels of calcium.

2. Brain fog

People, who are intolerant to gluten, often experience brain fog. This can be stimulated by various factors even though science noted that it is usually caused by the abnormal activity of gluten in the lgG, which in turn decreases cognitive ability.

3. Unstable function of the immune system

People, who are sensitive to gluten, may experience unstable immunity, particularly if lgA antibody is gluten intolerant. Moreover, lgA antibody is the main defense in the body against flu, common cold and other illnesses.

4. Constant exhaustion and fatigue

Constant exhaustion and fatigue may be caused by brain fog. Nevertheless, many health experts claim that the people, who are intolerant to gluten, have decreased levels of energy to start the day.

5. Sudden weight gain

People, who are sensitive to gluten, may gain weight suddenly. In fact, sudden weight gain in people with gluten intolerance may be caused by two factors:

– They experience inflammation as a result of gluten sensitivity
– Gut permeability or malabsorption, which are side effects of gluten intolerance

6. Constant migraines and headaches

If you suffer from constant migraines and headaches, you may be intolerant to gluten. Namely, migraines are very common for people who suffer from gluten intolerance. Migraines are manifested by severe pain. Avoid consuming gluten, if you are intolerant to it.

7. Autoimmune disorders

Celiac disease is an autoimmune disorder that makes the immune system attack the digestive tract after consuming gluten. Moreover, having celiac disease makes you prone to various autoimmune diseases, such as: autoimmune thyroid disease.

In addition, people with celiac disease are more common to have autoimmune diseases, such as: inflammatory bowel disease, autoimmune liver disease and diabetes type 1.

Symptoms of gluten sensitivity are widespread and can also include:

– Nutrient deficiency, as well as anemia (a lack of iron)
– Skin issues, including skin rashes, eczema, rosacea, and dermatitis.
– Reproductive issues and infertility
– Tingling and numbness in the legs and the arms
– Muscle and joint pain
– Chronic fatigue syndrome and reduced levels of energy
– Mood swifts, including depression and anxiety
– IBS and digestive symptoms, including cramping, abdominal pain, diarrhea, constipation, and bloating.
– Difficulty concentrating and remembering details
– A high risk of psychiatric and neurological disorders, including dementia, Alzheimer’s and schizophrenia

Gluten sensitivity is more than a digestive issue. Not only gluten intolerance affects the digestive tract, but it also affects the mouth, bones, skin, and other parts of the body. Gluten sensitivity can affect nearly all cells, tissues, and systems in the body, as it causes changes in the gut microbiota, gut bacteria that control everything in the body, from hormone production and nutrient absorption to cognitive ability and metabolic functions.


There are numerous factors, which can make people more likely to experience symptoms of gluten intolerance, including:

– Nutrient density and the overall diet
– Damaged gut flora
– Immune system status
– Genetic factors
– Hormonal balances

Gluten is thought to be an antinutrient, which is hard to digest even for people who are not gluten sensitive. Antinutrients are substances found in plant foods, like grains, seeds, nuts and legumes.

Gluten is one of those antinutrinets found in grains, which has these effects in people:

– It affects the normal digestion and leads to bloating, gas, diarrhea, and constipation, as a result of its effect on the gut bacteria.
– It may damage the gut lining, and lead to leaky gut syndrome as well as to autoimmune disorders.
– It acts with some amino acids (protein), minerals and vitamins, thus making them unabsorbable.


1. Try an elimination diet

It means to eliminate gluten from the diet in a period of one month, and after than adding it again. If you experience the same side effects after adding it back in your diet, it is clear that gluten was the main contributor of them.

2. Follow a gluten-free diet

Avoid gluten in your diet. It means to avoid consuming ray, wheat and barley. Also, pay attention to food labels, as gluten may be hidden in numerous packaged foods.

3. Get tests done

People, who test negative for two genes, which are related to celiac disease, are less likely to experience gluten intolerance.
