This feeling is called heartburn. It often moves up toward your throat. You might even notice a sour or bitter taste in your mouth. Some people call it indigestion or a sour stomach. Heartburn is a very common experience for many people. In fact, about 25% of people feel it at least once a month. It often happens within one hour after eating a large meal.

How does this burning happen in the body? One common cause is acid reflux. This is when stomach acid moves up into the esophagus. The esophagus is the tube that carries food to your stomach. In some people with GERD, the lining of this tube develops tiny gaps.

These gaps are called dilated intercellular spaces. They allow acid to seep in and hit sensitive nerves. These nerves then send pain signals to your brain. Other things like bile acid can also cause this irritation.

Doctors have many ways to study why heartburn happens. They might use an endoscopy to look inside the body.

During an endoscopy, a doctor can see the lining of the esophagus. They can also check for things like ulcers or inflammation. Another way is through pH monitoring. This test measures how much acid is in the esophagus. Some people also use a test called manometry. This helps doctors see how the muscles in the esophagus are moving. It helps them rule out different motility disorders.

There are many different things that can cause these symptoms. Heartburn can be linked to many medical conditions. These include peptic ulcers or inflammation in the stomach and pancreas. Even certain medications can cause it. Some people find that stress or a lack of sleep makes the pain feel worse. Activities that put pressure on the belly can also trigger it. This includes bending over, lifting heavy objects, or doing certain exercises. Lying down on your right side might even make it feel more severe.

Luckily, there are many ways to help manage the discomfort. Many people start with lifestyle changes. Avoiding fatty or spicy foods can make a big difference. Losing weight is another way to help. For mild cases, people often use over-the-counter antacids.

These work by neutralizing the acid. Other medicines, called H2 receptor antagonists, help by blocking histamine in the stomach. There are also stronger medicines called proton-pump inhibitors, or PPIs. These block an enzyme that makes acid. They are very effective but do not work immediately. They help make the refluxed contents much less acidic.
