Digestive conditions
A diagnosis is part
of your story.
Daily life is the rest.
Explore conditions across the digestive tract, liver, gallbladder, bile ducts, and pancreas. Your diagnosis and care help frame the daily questions you bring to Gutsphere.
Keep your care in the picture.
The explanation and instructions your clinician gave you.
What you followed, what was difficult, and what you noticed.
The questions and observations worth bringing back.
This broad directory includes common and less common conditions, including some that begin in childhood and continue into adult life. It does not enumerate every rare subtype. Listing a condition here does not mean Gutsphere treats it or has a dedicated program for it.
Your clinical team directs diagnosis and treatment. Gutsphere supports adults with understanding, recording observations, daily self-care, and the work around medical care.

See support around careRecord what happens
Preserve what you followed, your observations, and the practical difficulties worth discussing.
Try recording evidencePrepare a clearer conversation
Bring the relevant history and unresolved questions to your care team.

The groupings draw on public information from NIDDK, MedlinePlus, IFFGD, and the American Society of Colon and Rectal Surgeons. Each group links to its references. Sources were checked on September 11, 2026.
Related names and subtypes appear together where useful. Some conditions affect several parts of digestion, so these groups are a way to browse rather than a medical classification.
