Nausea and Vomiting - Why can’t I keep anything down?


What is a Nausea and Vomiting? Vomiting is the uncontrollable need to evacuate the contents of the stomach through the mouth. Nausea is the feeling of needing to vomit, even if you don’t vomit.  Vomiting is commonly known as throwing up, being sick or spewing.

Nausea and Vomiting Self Care

It’s easy to become dehydrated when nauseated or vomiting, so it’s important to keep drinking clear liquids like fruit juice, water and hydration drinks, even when you’re not thirsty. 

Over the counter medication can help control vomiting and nausea
, especially if caused by motion sickness, food poisoning or viral infection, but if symptoms persist for more than a few days, medical treatment may be required.

See a Doctor If:
You should seek medical attention if you have any of the following additional symptoms:

  • Blood in the vomit
  • Confusion
  • Decreased responsiveness
  • Fatigue / lethargy
  • Fever over 38⁰C
  • Rapid breathing (shortness of breath or panting)
  • Rapid pulse
  • Severe or persistent abdominal pain
  • Severe headache
  • Stiff neck
  • Vomiting and nausea do not cease after a few days of home care
