After quitting smoking, the patient’s gastric problems will gradually improve. When smoking, the tar and nicotine in cigarettes can stimulate the gastric mucosa, causing vasoconstriction and spasm of submucosal blood vessels, which in turn leads to ischemia and hypoxia of the gastric mucosa, which plays a role in destroying the gastric mucosa and reduces the barrier function of the gastric mucosa. Long-term smoking also promotes excessive secretion of gastric acid in the body, and inhibits the synthesis of prostaglandins, leading to the secretion of gastric mucous membrane mucus decline. All these factors will damage the normal function of the gastric mucosa, thus inducing gastric diseases. Therefore, smoking has the effect of inducing and promoting gastropathy, and also reduces the cure rate of gastropathy and increases the recurrence rate. Quitting smoking is very important for relieving the symptoms of gastric disease and promoting the healing of gastric disease. Smoking cessation should be carried out under the guidance of a professional doctor, and when uncomfortable symptoms occur, you should consult a doctor in time.
