I suspect that the blood in the upper tract is due to some kind of damage
to the lining. If this continues, see a gastroenterologist immediately -
there may be something else going on.

One possibility is Celiac disease, which can trigger Lactose Intolerance.
Celiac is the GI tract's inability to process gluten. The GI tract
(specifically, the cilia) can get damages to the point of bleeding,
resulting in severe anemia.

G'Luck.
