Abdominal distension, dull pain in the right lower abdomen, feeling sausage-like intestine, what disease is this?

Your illness should belong to irritable bowel syndrome. The cause of this symptom is unknown, and it is generally related to the stress of daily life.

Pay attention to food hygiene and digestibility every day; When the symptoms are severe, take Changle capsule+Guchang Zhixie pill after meals and montmorillonite powder on an empty stomach; Do some appropriate lightweight exercise every day; Learn to eliminate tension.

Gradually form good habits. If aftercare can be effective, I believe it will not be difficult to cure in the future.

Supplementary answer:

You can take some fructooligosaccharides if you have flatulence, no diarrhea and no defecation.
