Hello, Thanks for writing to us. Following suggestions would help you to moving out from this problem- 1. Eat your big meal at lunch instead of at dinnertime. 2. Eat at least two to three hours before lying down. 3. Avoid foods that are known to lead to heartburn, such as spicy foods, coffee, citrus fruit and juices. Especially if you eat any of these foods at dinnertime will increase your chances of having nighttime heartburn. 4. Eliminate late-night snacking. 5. Sleep with your head and shoulder on an incline.You can elevate your head in a couple of ways. You can place bricks or blocks under the legs at the head of your bed. You can also use a wedge-shaped pillow to elevate your head. 6. Sleep on your left side.Sleeping on the right side has been shown to worsen heartburn. 7. Stop smoking if you are smoker. 8. Avoid alcohol.Alcohol increases the production of stomach acid. 9. Take an antacid when heartburn hits. If you continue to experience frequent acidity at night, get this evaluated by a physician. He or she will be able to diagnose whether you are suffering from just occasional heartburn, or something that needs medical attention, such as gastroesophageal reflux disease, an ulcer, or a hiatal hernia. Wishing you good health... Regards. Dr Saurabh Gupta.
