Hi it might be due to gastritis.
Gastritis is an inflammation of the protective lining of the stomach.
Acute gastritis involves sudden, severe inflammation.
Chronic gastritis involves long-term inflammation that can last for years if it’s left untreated
Certain conditions and activities may increase your risk for developing gastritis
extreme alcohol consumption
routine use of nonsteroidal anti-inflammatory drugs (NSAIDs) like
ibuprofen and aspirin
cocaine use
tobacco use
stress
Gatritis can be reduced by antacids and probiotics
foods recommened are
high-fiber foods such as apples, oatmeal, broccoli, carrots, and beans.
low-fat foods such as fish, chicken, and turkey breast.
foods with low acidity, or are more alkaline, like vegetables.
drinks that are not carbonated.
Thank you take care.
