Hello, Thanks for the query to H.C.M. Forum. Certain medicines causes such type of sign visible in colon i.e. large intestine . In your case noting like this as you ate so many times yellow hot peppers . All things usually digested in small intestine , after this residual part of food stuff passes into large intestine and colon is last part before rectum and anal canal. This residual part is semisolid stool with mucus ( as this help in digestion ) . The yellow portion in your colon is nothing but is a stool with mucus ( sticky ) , so need not to worry. If some one eat large amount of iron preparation the color of stool become black color and so on. In my opinion this is not a cause of concern .If report of colonoscopy is normal otherwise need not to worry at all. Good luck, Dr. HET
