In digestion. Shy to go doctor for this!

I m 55 yrs old and I got my gal bladder removed some 6-7 yrs old due to stone and it got raptured and was advised to remove it immdly since it was supposed to blast since it was at the last stage is what my doctor told me. It was operated with surgery for 5 hrs and removed..post that, i was advised to avoid oil or junk food and need to be careful. Since my profession is sales, i often travel to places and there is no way to avoid oily food during travels and whatever best was avbl, i used to have but little only i prefer and sometimes, indigestion problem arise and later the following day morning, it will subside post passing motion. Many a times, i noticed a watery leakage of excess motion during fart which often occur even though passing motion not a issue but this leakage baffles me..i can notice stains on my inner wear. I maintain hygeine often wash hands and also wash asshole once I came bk home from office ..this one continues and I m so worried and bit shy to go doctor for this
