Waking up feeling gassy and bloated may result from eating certain foods, eating too quickly, or eating large meals. Other causes may include inflammatory bowel disease (IBD), diabetes, and gastroenteritis.

Bloating involves a feeling of fullness, pressure, or distension in the abdomen, possibly with the sensation of trapped gas. For many individuals, abdominal bloating and gas go away on their own and do not require any further medical evaluation or treatment.

Others may experience chronic or severe bloating and gas in the morning or at other times of the day, which may indicate an underlying health condition.

This article discusses possible short- and long-term causes of bloating and gas. It also explores treatment, prevention, and when to speak with a healthcare professional.

Almost everyone will experience short-term gas and bloating at some point during their lifetime. According to a 2020 review, its prevalence in the general population ranges from 16–31% and rises to 66–90% in people living with irritable bowel syndrome (IBS).

A person may not need treatment for infrequent bloating or gas. When eating habits or foods cause morning bloating, the symptoms will often go away on their own.

Persistent or severe bloating or gas may indicate a more serious underlying condition. People may find relief from their symptoms once they start treating and managing the underlying condition.

Treatments for underlying conditions can vary depending on the cause. A person will likely need to work with a healthcare professional for accurate diagnosis and treatment.

People with occasional bloating or gas may wish to try the following steps to help prevent these symptoms:

  • changing eating habits, such as eating more slowly, eating smaller meals, or chewing more thoroughly
  • keeping a food journal to help track which foods may be causing bloating and gas and discussing how to safely limit or remove them from the diet with a healthcare professional
  • reducing salt intake, particularly if eating a high fiber diet

According to a small 2021 study, people may also find that engaging in physical activity after eating may help reduce bloating. This activity does not need to be intense and may include going for a walk or other light activity.

People should consider seeing a doctor if they experience frequent cases of bloating or gas in the morning that does not subside or occurs alongside additional symptoms, such as diarrhea, vomiting, or constipation. This could indicate someone has an underlying condition.

Underlying medical conditions, such as IBS, IBD, and different cancers, can also cause bloating or gas that may occur when waking up.

Feeling bloated in the morning may not require treatment if symptoms are mild or go away after a short time. Severe or recurring bloating may indicate an underlying health condition. Treatment for the underlying condition may help improve bloating and gas symptoms.

A person should speak with a doctor if they are concerned about waking up with gas and bloating. A doctor may be able to recommend some lifestyle changes to prevent gas and bloating or order diagnostic tests if they suspect someone has an underlying condition.
