Thesos does not diagnose, treat, cure or prevent any disease. It is not a substitute for a doctor's advice, examination, diagnosis or treatment.

Quiz results, tests (such as Rome IV-style or severity questionnaires), gut scores, flare-risk estimates, likely triggers and AI-generated insights are informational. They are based on what you enter and on general research, and they can be wrong. Only a qualified clinician can diagnose IBS or rule out other conditions.

Never start, stop or change a medication, supplement or major diet (such as low-FODMAP) only because of the app. Talk to your doctor or a registered dietitian first.

Blood in your stool or black stools, unexplained weight loss, fever, persistent vomiting, difficulty swallowing, symptoms that wake you at night, anaemia, a lump in your abdomen, symptoms starting after age 50, or a family history of bowel cancer, coeliac disease or inflammatory bowel disease.

If you have severe abdominal pain, heavy bleeding or feel very unwell, call your local emergency number (112 in the EU and Serbia, 999 in the UK) or go to the nearest emergency department. Thesos is not monitored and cannot respond to emergencies.
