Could be: Black stools can reflect intestinal bleed. Medications and the mental stress of surgery could induce a peptic ulcer. Get a stool test from pharmacy to test for blood. If is blood need to call doctor; especially if light headed when stand up, which is a symptom which can indicate that blood volume is getting dangerously low. If you are taking iron tablets, these can cause dark stools.
