What is heartburn?
Heartburn is an uncomfortable burning feeling in your chest and throat. It doesn't have anything to do with your heart. However, the sensation is so close to your heart that it can feel like your heart is in pain.

You may also notice a sour taste in the back of your throat or feel like food or liquid is stuck there. You might experience coughing or your voice might become hoarse while the heartburn is going on.
Heartburn symptoms can feel worse when you bend over or lie down.
Heartburn is caused by stomach acid creeping up into your esophagus. Typically, the acid gets trapped behind a muscle called your lower esophageal sphincter (LES). The LES acts as a valve that opens to let food into your stomach. If it loosens, acid can escape and cause discomfort.
There are several different reasons why the LES can open up and lead to heartburn:
- Overeating: Over-filling your stomach can put pressure on the LES and allow it to open
- Pressure on the stomach: Obesity and constipation can push on the stomach and lead to heartburn
- Hiatal hernia: This happens when a small portion of the stomach pushes up into the diaphragm
- Pregnancy: Heartburn is a frequent symptom in pregnancy. Pregnancy naturally loosens many muscles, including the LES
Certain foods are also triggers for heartburn. Some of the common ones include:
Diagnosis for heartburn
Possible tests include:
Your doctor will have you drink a barium suspension that coats your esophagus, stomach, and upper small intestine. The coating lets doctors identify what is causing your heartburn.
Doctors can thread a small camera on a flexible tube down your throat to see your stomach and esophagus.
Your doctor will run a small probe down your throat into your esophagus to measure your pH levels for 24 to 48 hours. You can continue your day as normal while it’s in, just remember to keep a diary to record any symptoms and all the food you’ve eaten.
Your doctor inserts a tube from your nostril into your stomach. This tests the strength of your esophagus muscles at rest.
Treatments for heartburn
Heartburn can be easy to treat and prevent, though severe cases can require help from a doctor. Learn more about what you can do to get rid of heartburn.
If the non-prescription medicines don't help, your doctor can write you a prescription for stronger versions of these medicines.
You might find you feel better if you don't lie down too soon after eating. It can help to place 4- to 6-inch blocks under the legs at the head of your bed so gravity can keep the acid down. A wedge-shaped pillow would be an easier option, if you’d prefer.
Quitting tobacco may also help prevent heartburn.
Some people say an herbal supplement called Iberogast helps with heartburn, but you should only try this in moderation.
Chewing gum can provide some relief. You produce more saliva when you chew and saliva neutralizes the acid in your esophagus. As long as you’re not chewing large amounts of artificially sweetened gum, which could lead to diarrhea, this should be harmless.
Other procedures for GERD include:
- Fundoplication: This tries to tighten the LES muscles by almost completely wrapping the esophagus to stop acid from creeping up from your stomach
- LINX surgery: An emerging treatment where a surgeon implants a device to help manage your reflux
Possible risks and complications
The most common complication of heartburn is esophagitis, or the inflammation of the food pipe. This can cause constant burning pain, making it hard to swallow or eat. Without treatment, this can also lead to ulcers, bleeding, or both.
In less than 2% of esophagitis cases from people with GERD, a condition called Barrett’s esophagus can develop. This causes premalignant changes in the cells lining the esophagus.
2% to 5% of people with Barrett’s esophagus end up getting cancer. If you have severe esophagitis, take medications regularly to keep acid down.
If you’re using antacids to treat your acid reflux, overuse can lead to diarrhea or constipation. Try to pick antacids that have both magnesium hydroxide and aluminum hydroxide to avoid this. One causes diarrhea and the other causes constipation, so they work against each other.
