When the stomach lining becomes inflamed or swollen, the condition is known as gastritis. In particularly severe cases, the lining of the stomach may actually erode. The condition can be caused by any one of many factors, including alcohol abuse, bacterial or viral infection, bile reflux, drug use (particularly cocaine), viral infection, and even stress. Patients may begin to vomit blood and pass dark colored stools. Doctors commonly treat gastritis with a combination of antacids and proton pump inhibitors and removal of the cause of infection. If the condition is causes by a bacterial infection, the doctor may prescribe antibiotic treatment.
Marijuana can help gastritis patients deal with the more painful symptoms of the condition. When taken as part of a comprehensive treatment program, small amounts of marijuana may be useful in reducing pain.
