The symptoms of an uncomfortable stomach after taking anti-inflammatory drugs are caused by an imbalance in the intestinal flora, and many people will use anti-inflammatory drugs to treat their physical ailments. Anti-inflammatory drugs kill pathogenic bacteria in the intestinal tract while also causing harm to the beneficial bacteria in the intestinal tract, long-term use will lead to a decrease in the beneficial flora in the intestinal tract, thus causing an imbalance in the intestinal flora. Once the dysbiosis occurs in the intestinal system, it will induce indigestion, and the process of digestion and absorption of food will be affected, and also affect the peristaltic function of the intestine. Therefore, the patient will not only show abdominal distension, but also abdominal pain. People with intestinal dysbiosis can be treated with Clostridium Typhimurium and gastric enzyme combination, and should minimize the use of anti-inflammatory drugs in the future, otherwise the disease will be triggered again.
