What happens if the blood flowing to your small intestine is blocked off what are the signs and how long from the time that the blood is cut off till you have damage that can not be fixed? can you die from this?

Hello. : Hello. I think it depends on if this chronic ischemia or acute intestinal ischemia. Symptoms of chronic ischemia can include: abdominal pain that worsens over time, diarrhea, weight loss, nausea and vomiting, cramps or fullness of the abdomen after eating. Symptoms of acute intestinal ischemia can include: sudden mild to severe abdominal pain , distention of the abdomen, tender abdomen, blood in feces, nausea, vomiting, fever, an urgent need to pass stool or a really vigrous bm. I don't know if you are referring to strangulation of the bowel, which can obstruct flow and lead to gangrene. If you have sudden onset, severe abdominal pain that should be evaluated immediately.

If : If blood supply is completely cut of it is an emergency and can lead to death of the bowel within hours or the bowel can die and ultimately the patient can die. If the flow is decreased but not cut off then there may be more time for evaluation and treatment.
