What are the causes of positive fecal occult blood but normal blood counts?

There are many reasons for positive fecal occult blood but normal blood count, usually caused by hemorrhoids, intestinal inflammation, and peptic ulcers. 1. Hemorrhoids: hemorrhoid patients may be accompanied by bleeding during defecation, the stool sample taken without blood, the test will also appear in the fecal occult blood positive situation, because a small amount of hemorrhoidal bleeding will not cause anemia, so the blood routine is generally suggestive of normal. 2. Intestinal inflammation: mainly due to inflammatory stimulation caused by intestinal mucosal damage, may appear in the stool occult blood positive situation, this situation is generally normal blood routine. 3. Peptic ulcer: patients may have regular pain in the upper abdomen, and in severe cases, gastric bleeding may occur. Gastroscopy can be used for differential diagnosis, and after diagnosis, antacids such as omeprazole and ranitidine can be used to reduce the secretion of gastric acid, with the application of iron to prevent anemia, and in severe cases, bleeding needs to be stopped by gastroscopic intervention. In case of positive occult blood in stool but normal blood count, it is recommended to cooperate with doctors to identify the cause of the disease and then carry out symptomatic treatment.
