The H2 receptor lies in the parietal cells of the stomach wall. It is responsible for the release of gastric acid secretion - extra gastric acid secretion damages the tissues in the food pipe, stomach, and duodenum.

• Avoid acid or heartburn-triggering foods or drinks like onions, peppermint, chocolate, caffeinated beverages, citrus fruits or juices, tomatoes and high-fat and spicy foods.

• Before going to sleep, raise your bedhead, so your head and chest are higher than your feet. Do not use piles of pillows; one raised block is fine. This will not allow the stomach acid to backflow through your food pipe.

• Avoid taking alcohol and smoking cigarettes. Alcohol can raise the production of stomach acid leading to heartburn and acid reflux. On the other hand, nicotine smoking damages the valve (sphincter), preventing stomach acid backflow into the food pipe.

• Include high fibre-containing foods, berries, cherries, leafy green veggies (kale, spinach) and black peppers in your meal.

• Fermented dairy products like miso, sauerkraut, and kimchi contain probiotics which help prevent excess stomach acid production. Cranberry juice can be beneficial for peptic ulcers and H Pyroli infections.

• Avoid regular sitting continuously, as it can increase stomach acid production. Take a break of 5 minutes in 1 hour by brisk walking or stretching.
