Gluten intolerance is an increasingly recognized condition that affects a significant number of people around the world. Often underestimated or misunderstood, this sensitivity can manifest itself in a variety of ways, from gastrointestinal problems to neurological and skin symptoms. In this article, we will explore the 20 most common symptoms of gluten intolerance that you should be aware of to properly identify and address this condition.

1. Gastrointestinal Problems

Gastrointestinal symptoms such as bloating, abdominal pain, diarrhea or constipation are some of the most noticeable signs of gluten intolerance. These problems can arise after consuming foods that contain this protein.

2. Persistent Fatigue

Chronic fatigue and feeling constantly tired can be indicative of gluten intolerance. Although they can have various causes, it is important to consider gluten intolerance as a possible reason behind these symptoms.

3. Frequent Headaches

Recurrent migraines and headaches may be related to gluten intolerance in some people. If you experience this symptom regularly, it may be helpful to explore a possible gluten sensitivity.

4. Tingling or Numbness in the Extremities

Tingling or numbness in the hands and feet can be a neurological manifestation of gluten intolerance. These symptoms can appear after ingesting gluten and can be important warning signs.

5. Skin Problems

Gluten intolerance can trigger skin problems such as eczema or dermatitis herpetiformis, a condition characterized by painful skin rashes and blisters. These symptoms may be an immune system response to gluten exposure.

6. Unexplained Weight Loss

Unexplained weight loss can be a symptom of gluten intolerance, especially if it is accompanied by other gastrointestinal problems. Poor nutrient absorption due to intestinal inflammation can contribute to unintentional weight loss.

7. Mood Swings and Depression

Mood swings, irritability, and depression may be related to gluten intolerance in some people. The connection between gut health and mental health is increasingly recognized, and diet can play an important role in emotional balance.

8. Joint and Muscle Pain

Joint and muscle pain can be symptoms of systemic inflammation associated with gluten intolerance. These pains can vary in intensity and can affect the quality of life of those who experience them.

9. Inflammation in Various Parts of the Body

Gluten intolerance can trigger inflammation in different parts of the body, including joints, skin, and internal organs. This inflammation may be an immune response to gluten and can cause various symptoms.

10. Neurological Problems

Neurological problems such as dizziness, poor balance, and concentration difficulties may be associated with gluten intolerance. These symptoms can affect brain function and quality of life for those who experience them.

11. Changes in Sleep Patterns

Problems falling asleep or maintaining a regular sleeping pattern may be indicative of gluten intolerance in some people. The inflammation and hormonal imbalances associated with this condition can affect sleep quality.

12. Menstrual Problems in Women

Women with gluten intolerance may experience irregularities in their menstrual cycle, including heavy, irregular, or absent periods. The relationship between gluten intolerance and hormonal imbalances is still being researched, but it is believed that there is a connection.

13. Anemia Inexplicable

Iron deficiency and anemia can be consequences of gluten intolerance, especially due to nutrient malabsorption in the intestine. If blood iron levels are persistently low without a clear cause, it is important to consider the possibility of gluten intolerance.

14. Difficulties Concentrating and Memory Problems

Concentration problems, brain fog, and memory loss may be associated with gluten intolerance in some people. These symptoms can affect cognition and performance in daily activities.

15. Sensitivity to Extreme Cold or Heat

Sensitivity to extreme temperatures, whether hot or cold, can be a symptom of gluten intolerance. The hormonal imbalances and systemic inflammation associated with this condition can affect the body’s thermal regulation.

Swelling and tenderness in the joints can be symptoms of inflammation related to gluten intolerance. These symptoms may worsen after consuming foods containing gluten and may affect mobility and comfort.

17. Abdominal Discomfort After Consuming Gluten

Experiencing abdominal discomfort, gas, or bloating after eating foods containing gluten may be an indication of intolerance to this protein. These symptoms may appear shortly after ingestion and may last for several hours or days.

18. Digestion Problems Even After Eating Gluten-Free Foods

Some people with gluten intolerance may experience digestion problems even after eliminating gluten from their diet. This may be due to previous damage to the intestine or sensitivity to other food components.

19. Migraine Headaches

Migraines and severe headaches may be related to gluten intolerance in some people. Eliminating gluten from the diet can help reduce the frequency and intensity of these pains in those who are sensitive.

20. Changes in Appetite

Experiencing changes in appetite, such as an increase or decrease in appetite for no apparent reason, may be a symptom of gluten intolerance. Hormonal imbalances and inflammation can affect the appetite regulatory system in the body.


Gluten intolerance can manifest itself in various ways and affect multiple systems in the body. Recognizing and understanding these symptoms is crucial to obtaining a proper diagnosis and addressing the condition effectively. If you experience any of these symptoms persistently, it is important to seek medical advice and consider testing for gluten intolerance. Adopting a gluten-free diet can be beneficial for those who are sensitive to this protein and can help improve their quality of life and overall well-being.
