There are several explanations on why this happens but one of the main reasons is the food we eat. You need to know that certain foods increase the likelihood of us experiencing heartburn. So, by changing our diet, you will be able to find relief from heartburn and even decrease its frequency. This means that you may need to give up or limit some of the foods you eat in order for you to prevent experiencing heartburn. Heartburn is primarily a digestive condition where stomach acid comes in contact with the esophagus. When this happens, the acid will irritate the esophagus, causing you to feel a burning sensation that starts on your diaphragm and makes its way up to your chest. It is also accompanied by a bitter or sour taste in your mouth, which is basically the stomach acid your body regurgitated. If you love spicy food, such as Mexican food, then you may want to cut back on this type of food while you are pregnant. Spicy food can get your stomach to produce more acid, which will increase the likelihood of you experiencing heartburn. Fried and fatty foods should also be avoided as this type of food is hard to digest, which will force your stomach to produce more stomach acid. Your doctor will prescribe medications to manage heartburn more effectively and make other recommendations that will help you control or manage heartburn and let you live a more normal life. You also have to keep in mind that chronic heartburn can sometimes lead to much more serious complications, which will require you to seek immediate medical attention. But, you have to remember that relief will only be temporary and over the counter heartburn drugs will not prevent heartburn from returning and it will also not allow an injured esophagus to heal. The rule here is to see the doctor if you need antacids to get relief from heartburn for more than 2 weeks. The Causes of Heartburn and Why You Should Take It Seriously Have you ever experienced feeling a burning sensation that starts in your upper abdomen and builds up just behind your breastbone and that the pain and burning sensation is often accompanied by a sour taste in your mouth? If you have, then you are suffering from a condition called heartburn.
