Can thrombocytopenia cause GI bleeding?
Thrombocytopenia may be due to sequestration (eg, portal-hypertension–induced splenomegaly), reduced production (eg, hematologic disorders, chemotherapy), or increased destruction (eg, immune thrombocytopenia). Patients with thrombocytopenia appear to have an increased risk of GI bleeding (GIB).
Why does thrombocytopenia cause internal bleeding?
Thrombocytopenia can be mild and cause few signs or symptoms. In rare cases, the number of platelets can be so low that dangerous internal bleeding occurs.
What is pathophysiology of upper gastrointestinal bleeding?
Overview. The main inciting event in the pathogenesis of upper gastrointestinal (GI) bleeding is damage to mucosal injury. This mucosal injury can occur at various levels of GI tract. If the damage and bleeding is confined up to ligament of Treitz, it is defined as upper GI bleeding.
Can low platelets cause internal bleeding?
A decrease in platelets can cause easy bruising, bleeding gums, and internal bleeding. This disease is caused by an immune reaction against one’s own platelets.
When do you give platelets in GI bleed?
Thrombocytopenia — Patients with critical or life-threatening bleeding and a low platelet count (<50,000/microL) should be transfused with platelets.
What are the causes for thrombocytopenia?
What causes thrombocytopenia?
- Alcohol use disorder and alcoholism.
- Autoimmune disease which causes ITP.
- Bone marrow diseases, including aplastic anemia, leukemia, certain lymphomas and myelodysplastic syndromes.
- Cancer treatments like chemotherapy and radiation therapy.
What are the risk factors for thrombocytopenia?

- Have certain viruses.
- Have certain genetic conditions.
What are the possible causes of thrombocytopenia?
What is the pathophysiology of Melena?
What causes melena? Melena often results from damage to the upper GI tract lining, swollen blood vessels, or bleeding disorders. Peptic ulcer disease, which is characterized by painful ulcers or sores that develop in the stomach or small intestine, can result in melena.
What is the cause of gastrointestinal bleeding?
There are many possible causes of GI bleeding, including hemorrhoids, peptic ulcers, tears or inflammation in the esophagus, diverticulosis and diverticulitis, ulcerative colitis and Crohn’s disease, colonic polyps, or cancer in the colon, stomach or esophagus.
What happens if you have thrombocytopenia?
If you have thrombocytopenia, you don’t have enough platelets in your blood. Platelets help your blood clot, which stops bleeding. For most people, it’s not a big problem. But if you have a severe form, you can bleed spontaneously in your eyes, gums, or bladder or bleed too much when you’re injured.
