What Is Gluten Intolerance and Its Main Symptoms?


Gluten intolerance is a condition whereby the body produces an immune response to ingesting gluten. It is a protein found in many grains. This response causes symptoms to occur.

There are two types of intolerance: non-celiac gluten sensitivity and celiac disease. Both are autoimmune diseases, where the body’s immune system attacks its own tissues. Symptoms can include abdominal pain, bloating, diarrhea, constipation, or indigestion.

A person who tests positive for gluten intolerance should switch to a gluten-free diet for the rest of their life. Moreover, if you don’t stick to the diet, the condition will worsen.

Gluten intolerance can be a long-term problem, affecting the entire gastrointestinal tract and causing digestive discomfort and malnutrition. Fortunately, it is not a life-threatening condition.

What Is Gluten Intolerance?

Gluten intolerance is a long-term condition in which your immune system reacts to eating gluten. Foods that contain gluten can trigger this problem and make it worse. If you are experiencing symptoms of gluten intolerance, it is best to consult a healthcare professional. Depending on the severity of the condition, you may need to make changes in your diet.

Gluten is a protein found in grains such as wheat, rye, and barley. When you eat foods that contain gluten, your body’s immune system releases antibodies called immunoglobulin E. These antibodies trigger a range of symptoms. Some of these symptoms can include nausea, vomiting, bloating, abdominal pain, depression, and fatigue.

The symptoms of gluten intolerance can range from mild to severe. You can avoid gluten in your diet to reduce your symptoms. However, if your symptoms persist, you should consider visiting a gastroenterologist. The symptoms of gluten intolerance can also overlap with those of celiac disease.

Symptoms of Gluten Intolerance

In order to understand how gluten intolerance affects your body, you need to know about the symptoms. Here are some common symptoms of the problem.

Diarrhea and Constipation

One of the most common symptoms of gluten intolerance is diarrhea and constipation. When you have a gluten intolerance, your body stops processing the proteins in the food you eat. This can lead to a variety of problems, like diarrhea and constipation. For people who suffer from these symptoms, a gluten-free diet can relieve them. In fact, most studies have shown that gluten-free diets have a positive impact on patients with abdominal pain and gastrointestinal disorders.


Bloating is a very common symptom of gluten intolerance. It occurs when the stomach becomes full of gas. Often, it can cause pain and discomfort. Bloating can occur in the upper abdomen or lower abdomen. While bloating is not a symptom of celiac disease, it can be a symptom of non-celiac gluten sensitivity. Gluten intolerance can cause short-term bloating and stomach pain. Some symptoms associated with bloating include burping frequently, flatulence, cramping, and a distended belly.

Abdominal Pain

Abdominal pain is another common symptom of gluten intolerance. There are many different causes of stomach pain. However, if you suffer from chronic or frequent pain, it’s likely that you have gluten intolerance. This problem often causes bloating and gastrointestinal problems, which can further lead to abdominal pain. 


Fatigue is a common symptom of several autoimmune diseases. When you have gluten intolerance, your body is not able to process or use the protein as energy which causes fatigue. A recent study found that about 64% of people with gluten intolerance report fatigue. Using a fatigue severity scale, they discovered that patients’ scores were significantly higher than those of healthy volunteers.


Headaches are one of the many symptoms of gluten intolerance. This is a condition in which the immune system attacks the intestine. Another symptom of gluten intolerance is brain fog, which can make concentrating difficult. If you’re experiencing a chronic headache, it’s important to consult a doctor. A diagnosis of gluten intolerance can also be a good step toward finding the source of your headaches.


When a person has a gluten intolerance, they can experience many different symptoms. Some of these also include nausea and stomach pain. As you are not able to digest gluten, it often leads to problems like nausea. You might often feel nauseous after eating foods that contain gluten. 

Other Symptoms

A gluten intolerance can have many symptoms. Some of the most common are bloating, gas, fatigue, headaches, and diarrhea. These symptoms can appear immediately or at a later time. If you’re experiencing any of these, consult a doctor as soon as possible. Other symptoms of gluten intolerance also include rashes, depression, anxiety, joint pain, anemia, etc.
