Most cases of nausea and vomiting resolve within 6 to 24 hours with at-home treatment. However, it is important to see a doctor if you have frequent episodes of nausea and/or vomiting or if they last more than a day because they could be a sign of a serious illness. The doctor will examine you and ask questions about your health history. A physical exam may be done, and blood tests may be ordered to check for conditions like a low white blood cell count or liver function.

Nausea and vomiting can be caused by a variety of problems, including motion sickness, infections, migraines, pregnancy, gastrointestinal disorders and medication use. Many over-the-counter drugs can help relieve nausea and vomiting. If the nausea and vomiting are severe, you may need to be hospitalised.

Vomiting and nausea are common symptoms of many diseases and disorders, from viral gastroenteritis to cancer chemotherapy. The most common causes are infection, pregnancy and medications. Infections typically cause a sudden onset of symptoms, such as the toxin produced by Staphylococcus food poisoning or the enterotoxin in E.coli. Many gastrointestinal illnesses also cause nausea and vomiting, such as gastroenteritis, peptic ulcers and gallbladder disease. The underlying cause determines the severity of the symptoms and whether they are acute or chronic.

A person who has nausea and vomiting is at risk of dehydration, which can lead to complications. To avoid dehydration, drink clear liquids such as water or broth and take small sips. Avoid fatty, spicy or very sweet foods, as these can make the nausea worse. Often, people who are nauseous feel better when they rest, so try to stay in bed or on the couch. Drinking fluids with electrolytes, such as a rehydration solution, is especially helpful.

If your symptoms continue for more than a few days, call your doctor at Phenix Health. The doctor may need to order a blood test and sometimes an imaging study such as an ultrasound or x-rays to check for a heart attack or other serious condition.

If you are pregnant or have a medical condition that can lead to vomiting, such as a tumor, heart valve disease or kidney or liver problems, your doctor will prescribe medication and recommend other treatments that are safe for you. These include anti-nausea medicines or antiemetics. Medications can also be given through an IV in some situations. If your symptoms do not respond to these treatments, your doctor may suggest surgery or other procedures.

Nausea and vomiting are common side effects of some medications, such as anti nausea agents, corticosteroids, chemotherapy drugs and morphine. They are also a side effect of some autoimmune diseases and some treatments such as radiation therapy, anesthesia and invasive procedures. Your doctor will discuss these risks and benefits with you before you begin the treatment.

You should discuss all of your medications with your doctor, even those you take at home. Some of these can interfere with the effectiveness of other medications and increase the risk of adverse reactions.
