How are you diagnosed with gluten intolerance?
Gluten intolerance, also known as celiac disease, is diagnosed through a combination of blood tests and a biopsy of the small intestine. Here's a step-by-step process of how celiac disease is typically diagnosed:
1. Initial Consultation: If you experience symptoms that suggest gluten intolerance, such as digestive issues, weight loss, anemia, or unexplained fatigue, you should consult with a healthcare professional.
2. Blood Tests: The initial step in diagnosing celiac disease involves blood tests. These tests measure the levels of certain antibodies in your blood that are produced in response to gluten consumption. The most common blood tests used for celiac disease are:
- Tissue Transglutaminase (tTG) IgA Antibody Test
- Endomysial Antibody (EMA) Test
3. Positive Blood Test Results: If the blood tests indicate the presence of these antibodies, it suggests potential gluten intolerance, but a positive blood test alone does not confirm celiac disease. Further testing is needed.
4. Small Intestine Biopsy: The definitive test for celiac disease is a small intestine biopsy. During this procedure, a small sample of tissue is taken from the lining of your small intestine. This sample is then examined under a microscope to look for damage to the villi, the small finger-like projections that line the small intestine and help absorb nutrients.
5. Biopsy Results: If the biopsy shows damage to the villi, it confirms celiac disease. The level of damage can also help determine the severity of the condition.
6. Diagnosis and Treatment: Based on the blood test results and the small intestine biopsy findings, your healthcare provider will make a definitive diagnosis of celiac disease. They will then recommend appropriate treatments, such as adopting a strict gluten-free diet, to manage the condition.
It's important to note that if you suspect gluten intolerance, you should refrain from going on a gluten-free diet before undergoing diagnostic testing. This is because consuming a gluten-free diet can interfere with the accuracy of the blood tests and biopsy results.
If you have been diagnosed with celiac disease, it's crucial to follow the prescribed treatment plan and work closely with your healthcare provider to manage the condition and prevent long-term complications.
