Twice today I ve sat on the toilet, farted, and when I wiped there was a fair amount of yellowish mucus. I haven t been constipated, had diarrhea, had any stomach or intestinal pain. A little over a week ago I had a stomach bug and have been slightly more gassy recently. My brother had the same bug and has been kinda gassy as well. I have some gastrointestinal problems every 3-4 months (diarrhea ranging from once a week to daily, exact same time like clockwork) 2 weeks or so of probiotics and I m fine. It s been a month or so since my last episode, so whatever is going on shouldn t be related to that. I have 2 weeks of probiotics left and I started taking them. I assume right now I shouldn t be overly concerned. Just wanted to make sure. On a side note I ve started a bulking diet 2 days ago (I m really scrawny) I don t know if the sudden increase in food is causing the issue?
