Is black stool gastritis?

If the patient has severe gastritis, it may cause stomach bleeding. Iron ions in the blood react with sulfides in the stomach to form black ferrous sulfide, which is mixed with feces and excreted. Black stools are related to gastritis. If the patient often takes bismuth or iron, it may also cause black stools. Black stools are not gastritis.

If black stools are related to gastritis, the patient may be treated with acid inhibitors such as bismuth citrate ranitidine capsules, famotidine tablets, rabeprazole sodium enteric-coated tablets, etc. to relieve symptoms.
