Gluten intolerance, also known as non-celiac gluten sensitivity, affects a significant number of people worldwide. While it’s different from celiac disease and wheat allergy, gluten intolerance can still cause a variety of uncomfortable symptoms that impact your quality of life. If you’ve been experiencing digestive issues, fatigue, or other unexplained health problems, it’s possible that gluten could be the culprit. Here are 15 common signs that you may be gluten intolerant, helping you determine if removing gluten from your diet might be beneficial.

1. Bloating

Bloating is one of the most common signs of gluten intolerance. It occurs when your stomach feels swollen or full after eating, often accompanied by discomfort or a feeling of tightness. For those with gluten intolerance, consuming gluten can cause excess gas to build up in the intestines, leading to bloating. This uncomfortable symptom can last for several hours after a meal and may be more pronounced after consuming foods like bread, pasta, or baked goods.

2. Diarrhea or Constipation

Digestive disturbances like diarrhea or constipation are frequent in individuals with gluten intolerance. When gluten triggers an inflammatory response in the gut, it can disrupt normal bowel movements. Some people may experience chronic diarrhea, which can lead to dehydration and nutrient deficiencies, while others may struggle with constipation. The alternating pattern of these symptoms, often combined with stomach discomfort, is a key indicator of gluten intolerance.

3. Abdominal Pain and Cramping

Abdominal pain and cramping are common signs of gluten intolerance and can occur shortly after eating gluten-containing foods. The pain may range from mild discomfort to severe cramping, depending on the individual’s sensitivity. For some people, this pain is constant, while for others, it may come and go, often worsening after meals. The inflammation and irritation caused by gluten in the intestines can lead to this persistent discomfort.

4. Headaches and Migraines

Frequent headaches and migraines can be linked to gluten intolerance. While headaches can result from a variety of factors, those with gluten sensitivity often report intense headaches or migraines after consuming gluten. These headaches may be accompanied by nausea, sensitivity to light and sound, or a throbbing pain in the temples. If you notice a pattern of headaches occurring after meals that include gluten, it could be a sign of intolerance.

5. Fatigue and Low Energy

Feeling constantly tired or experiencing extreme fatigue is another common symptom of gluten intolerance. When the body struggles to digest gluten, it can lead to chronic fatigue, even if you’re getting enough sleep. This fatigue can be both physical and mental, making it difficult to concentrate or complete daily tasks. In some cases, gluten intolerance can also lead to iron-deficiency anemia, which further contributes to low energy levels and exhaustion.

6. Skin Issues

Gluten intolerance can manifest through various skin problems, including rashes, eczema, and acne. Dermatitis herpetiformis, a chronic skin condition characterized by itchy, blistering rashes, is directly linked to gluten sensitivity and celiac disease. Other skin issues like dryness, redness, or small, raised bumps can also be triggered by gluten. If you notice that your skin problems flare up after consuming gluten, it could be a sign of intolerance.

7. Joint and Muscle Pain

Joint pain and muscle aches are often overlooked as symptoms of gluten intolerance. However, the inflammation caused by gluten can affect more than just the digestive system—it can also trigger pain in the joints and muscles. This discomfort is commonly reported in the knees, hips, and lower back, and may be accompanied by stiffness or swelling. If you experience persistent joint pain without a clear cause, gluten could be a contributing factor.

8. Brain Fog

Brain fog refers to a feeling of mental confusion or difficulty focusing. People with gluten intolerance often describe feeling “foggy” or mentally sluggish, particularly after eating gluten-containing foods. This cognitive impairment can make it hard to concentrate, remember information, or think clearly. While brain fog can be caused by various health issues, if it consistently occurs after eating gluten, it could be related to gluten sensitivity.

9. Nausea

Nausea is another common symptom of gluten intolerance, especially after meals that include gluten. For some individuals, the nausea may be mild and short-lived, while for others, it can be severe enough to cause vomiting. The discomfort typically arises as the body struggles to digest gluten, leading to an upset stomach. If you frequently feel nauseous after eating foods like bread, pasta, or cereal, gluten may be the cause.

10. Weight Fluctuations

Unexplained weight loss or weight gain can sometimes be linked to gluten intolerance. For those with gluten sensitivity, the body may struggle to absorb nutrients properly, leading to weight loss. On the other hand, inflammation and bloating caused by gluten can contribute to weight gain. If you notice sudden or unexplained changes in your weight, and you’re experiencing other symptoms on this list, gluten could be the reason.

11. Anemia

Iron-deficiency anemia is common in those with gluten intolerance, especially in cases where the condition leads to malabsorption in the gut. Anemia occurs when there is a lack of healthy red blood cells to carry oxygen throughout the body, leading to symptoms like fatigue, weakness, and shortness of breath. If you’ve been diagnosed with anemia and other causes have been ruled out, gluten intolerance may be worth investigating.

12. Depression and Anxiety

Mental health issues like depression and anxiety can be linked to gluten intolerance. The gut-brain connection plays a significant role in how food affects mood and mental well-being. For some people, gluten triggers an inflammatory response that can worsen symptoms of depression and anxiety. If you’ve noticed mood swings, increased anxiety, or a decline in mental health that correlates with your diet, gluten could be a contributing factor.

13. Tingling and Numbness

Tingling or numbness in the hands and feet, also known as peripheral neuropathy, can sometimes be associated with gluten intolerance. This symptom is more commonly seen in individuals with celiac disease, but it can also occur in those with gluten sensitivity. The exact cause isn’t fully understood, but it may be related to nutrient deficiencies or inflammation caused by gluten. If you frequently experience tingling sensations without an obvious cause, it could be related to gluten consumption.

14. Autoimmune Disorders

Gluten intolerance is closely linked to autoimmune disorders. Celiac disease is itself an autoimmune condition, and those with gluten sensitivity are at a higher risk of developing other autoimmune diseases like rheumatoid arthritis, Hashimoto’s thyroiditis, and lupus. If you have an existing autoimmune disorder and experience digestive issues after consuming gluten, you may have an underlying intolerance.

15. Behavioral Changes in Children

In children, gluten intolerance can sometimes manifest as behavioral changes, such as irritability, hyperactivity, or difficulty focusing. While these behaviors can be caused by a variety of factors, if they worsen after consuming gluten, it may be worth exploring whether gluten intolerance is the cause. Removing gluten from the diet can lead to noticeable improvements in behavior, focus, and overall mood in some children.

Conclusion

Recognizing the signs of gluten intolerance can be the first step toward better health and well-being. If you’ve been experiencing any of these symptoms and suspect that gluten might be the cause, it’s important to consult with a healthcare provider. They can help determine whether gluten intolerance is the issue and guide you in making the dietary changes needed to improve your symptoms. While going gluten-free may seem challenging at first, the benefits of better digestion, increased energy, and overall health are well worth the effort.
