Gastritis is inflammation in the lining of your stomach. This lining (a soft tissue called mucosa) protects your stomach from the acids, enzymes and microorganisms that pass through it every day. Gastritis happens when your immune system detects a threat to this barrier. Your immune system triggers inflammation in the tissues to help fight infections and promote healing.
1- Loss of appetite, or feeling full soon after eating.
2- Stomach pain and bloating.
3- Nausea and/or vomiting.
You can treat your symptoms with over-the-counter (OTC) medications that soothe irritation and neutralize stomach acid, like proton pump inhibitors (PPIs) or Pepto Bismol®. These can bring temporary relief while your stomach is healing. You have to make sure that the cause of your gastritis has been eliminated, though. So, make sure to see a healthcare provider even if you’re self-medicating.
