What is Occult GI Bleeding?
Occult GI bleeding refers to blood loss in the gastrointestinal tract that isn't visible but can be detected through medical testing. It's often discovered through a positive fecal occult blood test or iron deficiency anemia without obvious symptoms. Unlike overt bleeding, which presents with visible signs like vomiting blood or black stools, occult bleeding requires careful medical evaluation to identify its hidden source.
Common Causes of Occult GI Bleeding
There are numerous potential causes for occult GI bleeding, making diagnosis challenging. Common culprits include colon cancer, peptic ulcers, and inflammatory bowel disease. Other possible sources are vascular issues like portal hypertensive gastropathy and small bowel tumors. Even less common causes, such as endometriosis or infections, can contribute and should not be overlooked.
Who is at Risk?
The risk of occult GI bleeding varies with age and medical history. Individuals over 50 are more likely to have colon cancer, while those under 40 might face small bowel tumors. Conditions like aortic stenosis or renal disease can increase the likelihood of bleeding from angiodysplasias. Recognizing these risk factors can guide further testing and treatment.
