Introduction
In general, long-term use of painkillers may damage the stomach. If you experience any discomfort, seek medical attention promptly. Proper medication use and healthy lifestyle habits can reduce the risk of gastric injury. Painkillers should be taken only under professional guidance—avoid long-term or frequent self-administration. Maintain regular mealtimes with consistent portion sizes to support normal gastric metabolic rhythm.

Generally, long-term use of analgesics may damage the stomach. If you experience any discomfort, it is advisable to seek medical attention promptly. A detailed explanation follows:

Most analgesics interfere with the gastric mucosal protective mechanism and inhibit the synthesis of protective substances. Once the gastric wall loses its adequate mucosal barrier, gastric acid directly contacts and erodes the gastric mucosa, leading to mucosal congestion and edema. Continued medication use progressively worsens mucosal injury, causing symptoms such as dull epigastric pain and acid reflux. Prolonged cumulative exposure may induce gastric erosion and impair normal digestive function.

Adhering to proper medication practices and maintaining healthy lifestyle habits can reduce the risk of gastric injury. Analgesics should be taken strictly under professional guidance; self-administration over extended periods or at high frequency should be avoided. Maintain regular mealtimes with consistent portion sizes to support normal gastric metabolic rhythms. Limit intake of raw, cold, or spicy foods to reduce gastric digestive burden, thereby promoting ongoing protection and repair of the gastric mucosa and reinforcing the gastric mucosal barrier function.
