Someone I know got partial constipation, lack of apetite and stomach reflux. After some month of triying to fix the reflux, they discovered it was intestine cancer when the cancer was big enough to block almost all the flow. IIUC from a sibling reply, you already used a few laxative, so perhaps a CT scan was the next step.
