What specific drugs are better to take when abdominal pain, diarrhea and blood in the stool appear, in order to have a better treatment effect, we must first find the specific diseases that cause these three symptoms, in order to be able to treat them symptomatically. If the symptoms of acute gastroenteritis occur simply because of unclean diet or because of a cold abdomen, it is best to take some antibiotics and anti-inflammatory drugs. The common clinical herbal medicines are enteritisin, laxative, or the application of some antimicrobials, includingloxacin capsules, haloperidol. If the abdominal pain and blood in stool are caused by special intestinal polyps, or malignant tumors, the best way is not to simply take medicine, but to do a colonoscopy to find the exact cause, and to perform surgical treatment according to the cause. If the bleeding and diarrhea is caused by internal or mixed hemorrhoids of the rectal mucosa, the main thing is to take systematic medication for hemorrhoids, including Ma Yinglong hemorrhoid suppositories and some hemostatic drugs, including hemagglutinin. These drugs are relatively effective for abdominal pain and blood in the stool. Therefore, when abdominal pain, diarrhea and blood in the stool occur, it is best to find the cause of the problem and to administer systemic medication for the cause.
