Bitter melon generally does not have much stimulating effect on the gastrointestinal tract, so if you have stomach pain after eating bitter melon, there may be some problems in the gastrointestinal tract itself. For example, if you have inflammation of the gastrointestinal tract, you should go to a regular hospital for gastroscopy or colonoscopy to see if there is congestion, edema or erosion of the mucosa of the gastrointestinal tract. If these problems exist, it is recommended to treat them with drugs that protect the gastric mucosa, along with some drugs that inhibit stomach acid. Adjust your diet, do not eat cold food like bitter melon for the time being, but eat light food, such as noodle soup, rice soup or millet porridge and other warm food, and eat something that is well digested to prevent irritation of the gastrointestinal tract mucosa, which may aggravate the symptoms of abdominal pain. Pay attention to drink more warm water, you can also drink ginger brown sugar water.
