Positive fecal occult blood requires a search for the cause and then a decision on the treatment plan. There are many causes of fecal occult blood, such as hemorrhoids, peptic ulcer, gastroenteritis, gastrointestinal tumors and other diseases. 1. Hemorrhoids: the most common cause of positive fecal occult blood, can be treated with hemorrhoid cream or suppository, such as Ma Yinglong musk hemorrhoid cream, hemorrhoid suppository, etc., and if necessary, can be considered surgical treatment. 2. Peptic ulcer: the cause can be clarified through gastroenteroscopy, and after diagnosis, omeprazole and colloidal bismuth can be given to relieve symptoms. If infected with Helicobacter pylori, use the quadruple method, i.e., a proton pump inhibitor such as omeprazole + a bismuth such as colloidal bismuth + two antibiotics such as amoxicillin, clarithromycin for eradication treatment, and if there is hemorrhage and other conditions such as feasible endoscopic or surgical treatment. 3. Gastroenteritis: such as ulcerative colitis, often pus and blood stools, causing positive fecal occult blood, can be given mesalazine and other drugs to relieve symptoms. 4. Gastrointestinal tumors: surgery or radiotherapy should be decided according to the condition. 5. Portal hypertension: Cirrhosis can lead to rupture and bleeding of esophagogastric fundic varices and portal hypertensive gastroenteropathy, which should be treated by lowering portal pressure, endoscopic and surgical treatment. Of course, we should also exclude the possibility of false positives caused by the intake of iron and blood products, etc. If you feel unwell, please consult the doctor promptly.
