Patients are advised not to take ibuprofen extended-release capsules when they have stomach pain. First of all, stomach pain is mostly due to excessive secretion of gastric acid and damage to the gastric mucosa, and taking ibuprofen capsules usually has no significant effect. Then again, ibuprofen capsules are non-steroidal anti-inflammatory drugs, which may aggravate gastric mucosal damage and aggravate gastrointestinal symptoms. When there is stomach pain, the first thing to do is to clarify the cause and understand whether there is chronic gastritis, gastric ulcer, gastroesophageal reflux disease, or even gastric cancer. After the cause is clearly identified, a combination of gastric mucosal protective agents, acid suppressants, pro-gastric motility drugs, or the addition of anti-H. pylori drugs should be given. Simply giving painkillers is not effective and may aggravate further damage to the gastrointestinal mucosa and aggravate the condition. In addition, in daily life, patients should pay attention to eating light, warm and soft, easily digestible food, avoid overeating, avoid the intake of spicy and irritating food, eat less and more meals, chew and swallow slowly to promote the recovery of the disease.
