The first thing you need to do is to avoid eating hard and crunchy food. These foods are hart to digest and it can also cause damage to your lower esophageal sphincter or LES. The LES acts as a valve that lets food in to the stomach and keeps stomach acid out. When the LES doesn t function properly, it will let stomach acid flow freely in to the esophagus when you experience acid reflux. 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. You should also stop smoking as nicotine can damage your LES or the lower esophageal sphincter, which is primarily responsible for preventing stomach acid from reaching your esophagus. After eating, you need to avoid lying down as this is the best position for the stomach acid to flow back or reflux in to your esophagus. Occasional or mild cases of heartburn will let the lining in your esophagus to recover and no long term damage will be done. But, if you experience heartburn on a regular basis, you may need to take this more seriously as repeated heartburn attacks will prevent your esophagus lining from recovering and cause serious damage to it. You should also stop wearing tight clothes as these clothes can produce pressure on your midsection forcing stomach contents, including stomach acid, to go up. Lastly, you should start losing weight. This will help relieve heartburn symptoms and you will also look better and feel more energetic if you do. This procedure will tighten your LES muscle and the muscle will be tied in such a way to prevent acid from flowing back in to the esophagus. This surgical procedure produced 85 percent success rate and is the last resort for treating heartburn. These are the different types of drugs and surgery that you can consider if you are suffering from heartburn.
