Hello Dear. You are having gastritis or acid peptic disease. Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress, or the use of certain medications such as aspirin or other anti-inflammatory drugs (which you are currently taking for your neck pain). It may also be caused by 1. Helicobacter pylori (H. pylori): A bacteria that lives in the mucous lining of the stomach; without treatment, the infection can lead to ulcers. 2. Pernicious anemia: A form of anemia that occurs when the stomach lacks a naturally occurring substance needed to properly absorb and digest vitamin B12 3. Bile reflux: A backflow of bile into the stomach from the bile tract (that connects to the liver and gallbladder) Treatment for gastritis usually involves: • Taking antacids and other drugs (such as proton pump inhibitors or H-2 blockers) to reduce stomach acid • Avoiding hot and spicy foods • For gastritis caused by H. pyloriinfection, your doctor will prescribe a regimen of several antibiotics plus an acid blocking drug (used for heartburn) • If the gastritis is caused by pernicious anemia, B12 vitamin shots will be given. • Eliminating irritating foods from your diet such as lactose from dairy or gluten from wheat Other tips- 1. Do not eat spicy food 2. Take medications without fail as prescribed by your doctor 3. Take little food at frequent intervals. Breakfast around 8am, small snack at 11am, lunch at 1pm, small snack at 4pm and dinner at 8pm 4. Drink plenty of water 5. Do not take much of stress. Stress aggravates gastritis 6. Do regular exercise. Atleast half an hour per day 7. Learn meditation techniques Hope i have answered your question. Feel free to contact me if you have any more questions. I ll be glad to help you.
