Gastrointestinal testing helps identify problems in your digestive system that might cause symptoms like bloating, diarrhea, constipation, or stomach pain. These tests check for infections, inflammation, or imbalances in gut bacteria, so you can find out what’s behind your discomfort. They also look for signs of nutrient absorption problems. Additionally, they can give insights into autoimmunity since gut inflammation may trigger and intensify autoimmune conditions.
These GI tests are simple to complete and give clear insights into how your digestive system is working. With the results, you can better understand what might be causing your symptoms and explore ways to support a healthier gut.
