I've been burping a lot lately at night. No stomach pains. How do I fix this?

Change feeding habit. Try not to eat to late at night or to close to the ti of going to sleep. Avoid food rich in carbs and spices sodas or excess of beer. Gas-x. Caps may help.
Belching. A hiatal hernia is a common finding and commonly cause belching. You will need to see a doctor to obtain a detailed history, a thorough exam, and tests that can confirm or rule out what we suspect you may have. This will include an upper GI series (x-ray) and upper endoscopy (egd).
