Diet & Lifestyle Advise

  • Avoid acid or heartburn triggering foods or drinks, such as 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 prevent stomach acid from backflowing 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 from flowing back into the food pipe.
  • Include high fibre-containing foods like berries, cherries, leafy green veggies (kale, spinach), and black peppers.
  • 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 pylori infections.
  • Avoid continuous sitting, as it can increase stomach acid production. Take a 5-minute break every hour by brisk walking or stretching.
