How long does it take to heal from erosive gastritis is related to the time of onset, the presence of complications and daily dietary care, etc. The healing time needs to be judged by evidence. For mild erosive gastritis, it can be cured in 4 weeks after early treatment with medication. For severe erosive gastritis, the treatment time will be relatively longer. If there is a combination of H. pylori infection, the overall treatment time is prolonged because it is necessary to first give H. pylori eradication treatment, i.e. triple therapy, for about two weeks, and then consider the treatment of erosive gastritis. At the same time, the daily dietary care of patients with erosive gastritis is also particularly important, with a soft, light diet and three regular meals a day to indirectly make the gastric disease better, while for patients who like spicy and irregular diet, the treatment time will be extended accordingly. In addition, regular work and rest is also essential for patients with gastric disease. Patients should try to avoid staying up late, relax, take medication on time, and carry out treatment and maintenance at the same time, so as to heal faster.
