    Nausea and vomiting - adults

    Emesis; Vomiting; Stomach upset; Upset stomach

    Nausea is thefeeling of having an urge to vomit. It is often called being sick to your stomach.

    Vomiting or throwing up is forcing the contents of the stomach up through the esophagus and out of the mouth.


    Many common problems may cause nauseaand vomiting:
    • Food allergies
    • Infections of the stomach or bowels, such as the "stomach flu" or food poisoning
    • Leaking of stomach contents (food or liquid) upwards (also called gastroesophageal refluxor GERD)
    • Medications or medical treatments, such as cancer chemotherapy or radiation treatment
    • Migraine headaches
    • Morning sickness during pregnancy
    • Seasickness or motion sickness
    • Severe pain, such as with kidney stones

    Nausea and vomiting may also be early warning signs of more serious medical problems, such as:

    • Appendicitis
    • Blockage in the intestines
    • Cancer or a tumor
    • Ingesting a drug or poison, especially by children
    • Ulcers in the lining of the stomach or small intestine

    Home Care

    Once you and your doctor find the cause, you will want to know how to treat your nausea or vomiting. You may be asked to take medicine, change your diet, or try other things to make you feel better.

    It is veryimportant to keep enough fluids in your body. Try drinking frequent, small amounts of clear liquids.

    If you have morning sickness during pregnancy, ask your doctor about the many possible treatments.

    The following may help treat motion sickness:

    • Lying down
    • Over-the-counter antihistamines (such as Dramamine)
    • Scopolamine prescription skin patches (such as Transderm Scop) are useful for extended trips, such as an ocean voyage. Place the patch 4 - 12 hours before setting sail. Scopolamine is effective but may produce dry mouth, blurred vision, and some drowsiness. Scopolamine is for adults only. It should NOT be given to children.

    When to Contact a Medical Professional

    Call 911 or go to an emergency room if:

    • You think vomiting is from poisoning
    • You notice blood or dark, coffee-colored material in the vomit

    Call a health care provider right away or seek medical care if you or another person has:

    • Been vomiting for longer than 24 hours
    • Been unable to keep any fluids down for 12 hours or more
    • Headache or stiff neck
    • Not urinated for 8 or more hours
    • Severestomach or bellypain
    • Vomited three or more times in 1 day

    Signs of dehydration include:

    • Crying without tears
    • Dry mouth
    • Increased thirst
    • Eyes that appear sunken
    • Skin changes -- for example,if you touch or squeeze the skin, it doesn't bounce back the way it usually does
    • Urinating less often or having dark yellow urine

    What to Expect at Your Office Visit

    Your health care provider will perform a physical examination, and will look for signs of dehydration.

    Your health care provider will ask questions about your symptoms, such as:

    • When did the vomiting begin? How long has it lasted? How often does it occur?
    • Does it occur after you eat, or on an empty stomach?
    • What other symptoms are present -- abdominal pain, fever, diarrhea,or headaches?
    • Are youvomiting blood?
    • Are you vomiting anything that looks like coffee grounds?
    • Are you vomiting undigested food?
    • When was the last time you urinated?

    Other questions you may be asked include:

    • Have you been losing weight?
    • Have you been traveling? Where?
    • What medications do you take?
    • Did other peoplewho ate at the sameplace as you have the same symptoms?
    • Are you pregnant or could you be pregnant?

    The diagnostic tests may be performed:

    • Blood tests (such as CBC with differential, blood electrolyte levels, and liver function tests)
    • Urinalysis
    • X-rays of the abdomen

    Depending on the cause and how much extra fluids you need, you may have to stay in the hospital or clinic for a period of time. You may need fluids given through your veins (intravenous or IV).
