I have diarrhea almost every day for the past month, sometimes up to five times in a day. I've had lots of bloating and stomach pain and very poor appetite. I've been strictly gluten-free sugar free and lactose free since stomach problems started. I've been having very odd colored BM's, white, yellow, orange, green, black. Very flat also and lots of mucus. The other day I had a sudden rush of what felt like somebody poured a glass of cold water right into my stomach and I wanted to use the bathroom and I had a flat, triangular shaped stool. Any idea what could cause this??
