From about last 2 months, i am getting diarrhea once or twice in a week. Can't able to track down what's causing it as I am eating always home made food. Diarrhea is consistency wise not frequency wise as I go for motion only once in a day. During the motion, first come normal stool then some loose or watery/oily stool and sometimes dark in colour. Also feeling some weird noises and watery type movement in stomach. Please help i am very anxious due to this. Blood tests CBC
LFT KFT
thyroid urinalysis were normal. Please help. Age 22. Attaching pic for reference.
