Gastrointestinal bleeding should be treated symptomatically. First of all, find out the reason. Is the color of bleeding bright red, brownish red or dark brown? If the bleeding is bright red, it means that the blood vessels around the anus are broken, which may be a kind of diseases such as hemorrhoids. Ma Yinglong hemorrhoid ointment can be used, and then oral hemorrhoid tablets can be used for treatment, and drink plenty of water. If it is reddish brown, it may be colon bleeding. Go to the anorectal department and take photos to rule out the possibility of colon cancer. If the blood is dark brown, it is probably bleeding from gastric ulcer. You should take Yunnan Baiyao or Yunnan Yao Hong capsules, plus gastric mucosal protective agents, such as sucralfate or aluminum hydroxide tablets.
