How long does chronic mild superficial gastritis take to heal?

Patient's question:

Gender: Male
Age: 23
I don't have a stomachache, but I do have acid reflux, belching, and sometimes feel like I'm not getting enough air when I'm uncomfortable. My hands and feet get cold, and I sometimes feel dizzy. I know this is due to hypoxia caused by belching and insufficient blood supply, which is a normal phenomenon.
I had an endoscopy a few days ago and was diagnosed with bile reflux gastritis, duodenitis, and a gastritis in the gastric antrum.

Doctor's answer:

Analysis of the condition: In your case, it is still important to pay attention to timely maintenance, which is key.
Guidance: Chronic superficial gastritis does not necessarily have severe symptoms. With proper maintenance, some people may not need medication. It is still important to focus on a diet that is easy to digest and try to consume more liquid foods. Under the guidance of a doctor, using some stomach-nourishing supplements like Hongtou Granules or Shenqi Jianwei Granules in combination can be very effective.
