Hi from the last 8 -9 months i am on a weight loss spree. I have lost almost 15kgs, but have made changes in my diet for eg- i am now having 4 roti's with chicken without salad(occasionally). Followed by 1 scoop protien powder along with 4 egg whites. Also i take
vitamin E,
calcium, and an antioxidant cap for my daily diet. For the last few months my stool has become very dark in colour (black patches to be precise). I dont have any pain in my stomach or feel indigestion, just curious to know is this normal or should i see a doctor. Please help me out
