Heartburn and nausea are common gastrointestinal complaints and common symptoms of indigestion. This means they often occur at the same time.
Heartburn is also called gastroesophageal reflux. It has nothing to do with the heart. Rather, it occurs when acid from the stomach flows backward into the esophagus — the tube that connects the throat to the stomach.
People often describe heartburn as a burning sensation just behind the breastbone. Some people also experience a bitter or sour taste in the back of the throat. The effects can last for several hours and tend to be worse after eating.
Nausea describes the urge to vomit or be sick. The sensation may come just before vomiting or can happen on its own.
In this article, learn more about the link between heartburn and nausea, as well as possible causes of these conditions occurring simultaneously.
Heartburn and nausea are both symptoms of indigestion, so they commonly occur at the same time.
Indigestion is also called dyspepsia. It describes a group of gut-related symptoms.

When someone suffers from heartburn and nausea due to passing indigestion, it is not usually anything to worry about.
These symptoms are often due to eating food that is too spicy or drinking too much alcohol. If this is the case, the symptoms tend to go away over time without treatment.
If a person experiences the symptoms more frequently, it could be a sign of an underlying health condition. These conditions can include the following:
Gastritis means inflammation or swelling of the stomach lining from the acidic digestive juices in the gut.
Some people will experience acute gastritis, meaning it comes on suddenly and only lasts a short time. Others have chronic gastritis, which can last for years if they do not receive treatment.
- Helicobacter pylori (H. pylori) infection
- damage to the stomach lining
- the body’s immune system
Other symptoms include pain or discomfort in the upper abdomen, nausea, and vomiting.

Peptic ulcer disease
A peptic ulcer, or stomach ulcer, is a sore on the stomach lining. Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and aspirin, can cause a stomach ulcer. An H. pylori infection may also lead to the problem.
The most common symptom of a peptic ulcer is a dull or burning pain between the belly button and the breastbone.

Symptoms of indigestion are common in pregnant people.
Heartburn can happen at any point during the pregnancy due to fluctuating hormones affecting the muscle that keeps food in the stomach. This change can allow acid to move from the stomach to the esophagus.
Nausea is also a symptom of morning sickness, which is another common occurrence in pregnancy.
Despite the name, morning sickness can happen at any time of the day or night. A person may only feel nauseated, or they may also vomit.

Most water is neutral, meaning it is neither acidic nor alkaline. Water cannot neutralize stomach acid but can aid the movement of food through the stomach into the small intestine. Proper digestion can reduce symptoms of acid reflux.
What foods and drinks cause heartburn?
Foods and drinks that commonly cause heartburn include:
- spicy foods
- oily and fried foods
- carbonated drinks
- acidic fruits and juices
Are heartburn and nausea normal?
Heartburn and nausea are often symptoms of a gastrointestinal dysfunction, such as acid reflux. However, both are common and typically harmless. Many cases of heartburn and nausea will resolve independently and result in no ill effects.
Heartburn and nausea are both symptoms of indigestion and often happen together. While they can be painful, they are not usually anything to worry about. A range of over-the-counter treatments is available to reduce symptoms.
More frequent bouts of heartburn and nausea may indicate an underlying health condition. Anyone with indigestion that lasts longer than 2 weeks should speak to a doctor.
