Sometimes you will regurgitate and taste something bitter or sour in your mouth during an episode of heartburn. This is because the stomach acid may have reached your mouth, which explains the sour or bitter taste. Mild cases of heartburn are considered more of a nuisance than a real condition that can have a large impact on people s life. This will help dilute the acid in your stomach, which will make it less potent. Lastly, if you must eat meat, you have to eat lean meat that has little fat on it.

Chronic heartburn is also a sign or symptom of a more serious condition called GERD or Gastroesophageal Reflux Disease. Well, if you experience heartburn once a month, this is considered to be acute or mild. If you experience heartburn once a week, this is a moderate case of heartburn.
