Recurrent Vomiting: Causes & When to See a Doctor
Vomiting is a common symptom that is usually short-lived and harmless, such as with a stomach bug. But vomiting that keeps coming back, or that persists, can be a sign of a problem in the digestive system that deserves assessment — particularly if it is accompanied by weight loss, blood, or an inability to keep food down.
This page explains what recurrent vomiting can mean and when to seek care.
What does recurrent vomiting mean?
Recurrent vomiting can result from many things — from infections and migraines to problems with the stomach emptying or a blockage in the digestive tract. The pattern offers clues. Vomiting of undigested food some time after eating can suggest a problem with stomach emptying or a narrowing; vomiting with severe abdominal pain and a swollen abdomen can suggest a blockage, which is an emergency.
Persistent vomiting also risks dehydration, so it should not be allowed to continue unchecked.
Common causes
- Gastroenteritis and other infections
- Acid reflux and gastritis
- Migraine, motion sickness and certain medicines
- Pregnancy
Less common causes
- A blockage (obstruction) of the bowel — a surgical emergency
- A narrowing where the stomach empties (gastric outlet obstruction)
- Gallstones causing pain and vomiting
- Stomach cancer or other tumours
- A trapped (obstructed) hernia
When should you seek medical attention?
- Vomiting that is persistent or keeps recurring
- Vomiting blood, or 'coffee-ground' vomit — seek urgent care
- Vomiting with severe abdominal pain and a swollen abdomen — seek urgent care
- Vomiting with weight loss or inability to keep fluids down
- Signs of dehydration: dizziness, reduced urine, marked thirst
How is the cause diagnosed?
- A careful history and examination
- Blood tests to assess hydration and look for a cause
- Upper GI endoscopy to examine the stomach and food pipe
- Abdominal X-ray or CT scan if a blockage is suspected
- Ultrasound for gallstones where relevant
How recurrent vomiting is treated
Treatment depends on the cause. Many causes settle with anti-sickness medication, fluids and treating the underlying problem, such as reflux or an infection. Where vomiting is due to a narrowing, a blockage, gallstones or a tumour, the specific condition is treated — sometimes urgently.
An important first step is preventing dehydration, particularly in older people and children, alongside finding the cause.
When surgery may be needed
Surgery is needed when vomiting is caused by a condition that requires an operation — most urgently, a bowel obstruction or a trapped hernia, and also a narrowing where the stomach empties, gallstones, or a tumour such as stomach cancer. A GI surgeon can quickly determine whether such a cause is present and whether surgery is required.

Recurrent Vomiting: frequently asked questions
When is vomiting an emergency?
Seek urgent care if you are vomiting blood or 'coffee-ground' material, if vomiting comes with severe abdominal pain and a swollen abdomen (which can mean a blockage), or if you cannot keep any fluids down and are becoming dehydrated. These need prompt assessment.
Can gallstones cause vomiting?
Yes. Gallstones can cause bouts of pain and vomiting, particularly after fatty meals, and gallstone complications such as an inflamed gallbladder or pancreatitis often cause vomiting. An ultrasound is the simple test that confirms whether gallstones are present.
