Your chest feels like it s on fire and the pain is radiating from your diaphragm to your throat. The pain is accompanied by a bitter or sour taste and you feel as if food is reentering your mouth. What you just experienced is a severe case of heartburn. Although the name suggests that it may be related to the heart, you have to remember that heartburn has nothing to do with the heart. This is primarily the reason why you have to go to the doctor in order to get it diagnosed properly and determine the cause of heartburn. The doctor may try to diagnose you biochemically or mechanically. The biochemical method of diagnosing means that a probe will be placed via the nose and in to the esophagus. If you want a more effective type of antacid, you will want to go for antacids that contain calcium carbonate. They are known to be the most potent in neutralizing stomach acid and are very popular among people who suffer from heartburn. When taking drugs, always remember that you should follow the instructions in the label. 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. If you are already throwing up blood or passing blood in your stools, experiencing dizziness, severe pain or light headedness, have difficulty in swallowing, feeling of dehydration, and you lost weight unintentionally, this is the time that you should call your doctor and go to the hospital. Eating big meals will worsen your heartburn problem because your body or your stomach will produce excess acid in order to digest huge amounts of food. This is why you have to try and eat smaller meals at least 6 times a day instead of eating 3 large meals a day. This will lessen your stomach s production of acid, which will help in managing heartburn. Firstly, you have to realize that heartburn is caused by a backflow of stomach acid in to the esophagus. This happens because the muscles in your stomach relax because of the hormonal changes in your body during pregnancy. The best thing that you can do is to avoid eating large meals. Instead of eating 3 large meals a day, try to eat 6 smaller meals daily.
