My husband and I are great seafood lovers. The last time we flew to Thailand more than half the time we spent on the fish market, it was a paradise for people like us. We were never adherents of a healthy lifestyle, until we got home from the trip. My husband had a stomach ache at night, the pain was very strong. I was scared and the only thing that could do this was to call an ambulance. He was hospitalized, after the examination the doctor diagnosed gastritis. My husband had to change his diet and refuse such delicates as sea ducks, it was the biggest loss for him. Below I will tell in more detail what I learned about gastritis from our doctor.
