Gluten sensitivity is when the body reacts negatively to gluten, a protein in grains such as wheat, rye, and barley. This may not involve a severe immune response or damage to the digestive system, as observed in celiac disease, which causes inflammation in the small intestine. Being sensitive to gluten can, however, lead to discomfort and other symptoms. One can confirm they are sensitive to gluten with a few simple tests.

Symptoms
People with gluten sensitivity may experience the following symptoms: Bloating, nausea, Skin rashes or eczema, brain fog or difficulty concentrating, headaches or migraines, and fatigue. Joint pain, abdominal pain or discomfort, diarrhea or constipation, and depression or anxiety are some of the other symptoms. Some of these symptoms may also indicate other underlying health conditions, such as celiac disease, irritable bowel syndrome (IBS), or food allergies. So, doctors use health history, physical examination, and laboratory tests to diagnose gluten sensitivity. One should seek medical attention if they experience any of these symptoms regularly.

Diagnosing gluten sensitivity
Any gluten-related disorder can cause mild to severe symptoms like bloating, abdominal pain, diarrhea, and fatigue. But is there a test for gluten sensitivity? A few tests can help diagnose celiac disease and gluten sensitivity. Doctors may recommend the following diagnostic tools:

Blood tests: Gluten sensitivity blood tests are the most preferred diagnostic tools for this health concern. The blood test measures antibodies produced in the blood in response to gluten. Antibodies, such as IgG and IgA, are most commonly measured for gluten sensitivity. A high level of these antibodies may indicate gluten sensitivity.

Elimination food plan: An elimination food plan is not a test but one of the best ways to help identify gluten sensitivity. Here, over the course of several weeks, gluten is entirely removed from the meal plan and then reintroduced to see if the symptoms return. The appearance of symptoms after reintroducing the protein may indicate gluten sensitivity.

Genetic tests: Here, the test can determine genetic predisposition to gluten sensitivity. The test looks for genetic markers associated with an increased risk of gluten intolerance. However, being sensitive to gluten may not always mean one has genetic markers indicating the same.

Stool tests: Here, the amount of antibodies produced in response to gluten is measured in the stool. The tests measure antibodies produced in the gut, where the immune system is most active. However, the validity and accuracy of such tests have not been confirmed.

These tests can help diagnose gluten sensitivity, but they are not always accurate. The results may show false negatives or positives, so one may not get a precise diagnosis. Sometimes, a combination of tests may be required to confirm sensitivity to wheat or gluten and celiac disease.

Benefits of getting tested
Diagnosing gluten sensitivity can have several important benefits for those experiencing symptoms or dealing with discomfort after having gluten-heavy foods. Some of the key benefits of getting tested for gluten sensitivity are:

Improved quality of life: The symptoms of gluten sensitivity may be reduced or eliminated by identifying and eliminating gluten from the meal plan. So, one could find relief for bloating, abdominal pain, diarrhea, and fatigue, among other symptoms. A proper diagnosis and treatment plan can improve their quality of life and make them feel better.

No unnecessary treatment: One may undergo unnecessary treatments and take prescriptions that may not treat the root cause of their discomfort. Once they have been tested for gluten sensitivity, they can find better ways to cope with the issue and avoid unnecessary procedures and prescriptions. 

Lower risk of complications: If left untreated, gluten sensitivity can lead to malnutrition, osteoporosis, anemia, and other autoimmune disorders in extreme cases. Identifying and treating gluten sensitivity early on can reduce the risk of these complications.

Better management of co-existing conditions: Gluten sensitivity is often associated with other health conditions, such as celiac disease, irritable bowel syndrome (IBS), and autoimmune disorders. Doctors can develop customized treatment plans that address patient concerns and help them manage symptoms better after diagnosing the exact issue.

Better food choices: A healthcare provider or nutritionist can help one identify gluten-free foods that meet their nutritional needs once they have been diagnosed with gluten sensitivity. One may have to find gluten-free alternatives to their favorite foods, like quinoa or rice instead of wheat. So, one can make informed nutritional choices that support their health and well-being with the right guidance and support.

Gluten sensitivity is a growing concern, however, it may not cause an immune response or damage to the digestive system like severe disorders. If one experiences signs of discomfort associated with the issue, they should get tested and consult a doctor to check if a gluten-free food plan can improve their health. Getting a prompt diagnosis can help improve the quality of life, prevent complications, and avoid unnecessary treatments. So, one should consult a healthcare provider and undergo the appropriate gluten sensitivity tests as soon as they notice common symptoms.
