The body contains a substance called prostaglandin, which amplifies the “pain” signal when people feel pain. For this reason, many painkillers are designed to inhibit the release of prostaglandins for the purpose of pain relief, including the more familiar ones such as fen-phen, aspirin, and painkillers. In addition to amplifying pain signals, prostaglandins have an important role in protecting the gastric mucosa, when the secretion of prostaglandins is inhibited by painkillers the gastric mucosa naturally loses a barrier, the acidic digestive juices in the stomach can take advantage of the opportunity to stimulate and damage the stomach wall, causing ulcers, erosion or even bleeding perforation. If a “stomach patient” blindly uses painkillers when he or she has a “stomachache”, the following situations are likely to occur: 1. the use of painkillers will mask the patient’s condition and lead to gradual deterioration; 2. the gastric mucosa of the already injured stomach patient will lose 2. the loss of protection of the gastric mucosa of the already injured patient, resulting in dangerous situations such as “ulceration, erosion or even bleeding from perforation”. The doctor’s tip: In summary, painkillers are, after all, drugs, and they are poisonous, so don’t try to “eat it and eat it”.
