  • Procedures may be done to seal or clot your blood vessels. Argon gas, a laser, or heat may be used to seal the bleeding blood vessel. This may be done during an endoscopy or colonoscopy. Medicine may be delivered to your blood vessel to clot it during an angiography.

You may have other bleeding episodes, even after you have received treatment. Over time, blood loss can lead to anemia. Anemia is a low number of red blood cells. This prevents your body from carrying enough oxygen to your body. Anemia can cause fatigue, weakness, and shortness of breath.
