Learning About Post-Tussive Vomiting

Post-tussive vomiting happens when you vomit right after an intense coughing fit. For some people, coughing hard can trigger their gag reflex. This can lead to vomiting. Children tend to have a more sensitive gag reflex than adults. But adults can have it too. Post-tussive vomiting is more common in children who have asthma. Illness can also cause severe coughing fits that lead to vomiting.

Post-tussive vomiting can be caused by conditions like asthma. It can also be caused by respiratory problems such as bronchitis, respiratory syncytial virus (RSV), pneumonia, or other upper respiratory infections. Pertussis (whooping cough) can also cause it.

Your doctor will ask you about your symptoms and do a physical exam. The doctor may want to do imaging tests such as a chest X-ray. These tests can help your doctor find out what may be causing your cough.

Your doctor will treat the cause of your cough. You may also get medicines that can help with the cough.

To help prevent post-tussive vomiting:

• Get vaccinated for pertussis. This vaccine should be given at as early an age as possible. Adults can get a vaccine if they weren't vaccinated as a child. One dose is recommended during pregnancy.
• Don’t smoke, vape, or use other tobacco or nicotine products. If you need help quitting, talk to your doctor about quit programs and medicines. These can increase your chances of quitting for good.
• Get treated for any infections or conditions that may be causing your cough.

Contact your doctor if you are:

• Coughing up blood.
• Having difficulty breathing.
• Dehydrated from vomiting.
