Chronic inactive gastritis c2 needs to be treated by improving lifestyle and using medications. Chronic inactive gastritis c2 means that the patient’s gastrointestinal mucosa is inflamed and the inflammation has progressed to type c2, i.e., the atrophy has exceeded the angle of the stomach and reached the side of the lesser curvature of the gastric body. 1. Improve lifestyle: The first step in treating chronic inactive gastritis c2 is to improve poor lifestyle, eat regularly, avoid oily and spicy food such as fatty meat and chili peppers, and replenish sufficient amount of fresh vegetables and fruits every day. Quit smoking and drinking, ensure sufficient sleep, and do not stay up late. In addition, it is also important to maintain emotional stability and a pleasant mood. 2. Use of drugs: you need to choose the relevant and reasonable drugs according to the specific symptoms, such as acid-suppressing drug omeprazole, pro-dynamic drug domperidone tablets, mucosal protection pectin bismuth and other drugs. Try to avoid drugs that damage the gastric mucosa, such as non-steroidal anti-inflammatory drugs celecoxib and so on. Patients with chronic inactive gastritis c2 should adjust their life, use medication under the guidance of a doctor, and have regular reviews to prevent further development of the disease.
