Nausea and Vomiting, Age 12 and Older
About this symptom
Nausea is a sick feeling in the pit of your
stomach. When you are nauseated, you may feel weak and sweaty and have too much
saliva in your mouth. You may even vomit. This forces your stomach contents up
your esophagus 
and out of your mouth. Most of the time
nausea and vomiting are not serious. Home treatment will often help you feel
better.
Nausea and vomiting can be a symptom of another illness. Nausea and vomiting may be caused by:
- Illness caused by a virus, such as viral stomach illness (gastroenteritis).
- Food poisoning.
- Stress, nervousness, or a mental health problem, such as depression or an anxiety disorder.
- Medicines, such as antibiotics, birth control pills, or heart medicines.
- Pregnancy. "Morning sickness" may be one of your first symptoms.
- Problems with abdominal organs.
- Migraine headache.
- Heart attack.
- Stroke.
- Head injury.
- Alcohol or drug abuse or withdrawal.
- Overeating.
- Eating disorders, such as anorexia or bulimia.
- Disorders of the inner ear, such as labyrinthitis, Ménière's disease, or motion sickness.
- A side effect of radiation therapy.
Nausea or vomiting also may be a symptom of a problem or a disease, such as:
- Diabetes.
- Liver disease (hepatitis or cirrhosis).
- Inflammation of the pancreas (pancreatitis).
- Inflammation or irritation of the lining of the stomach (gastritis).
- Ulcer disease of the stomach or small intestine (peptic ulcers).
- Gallbladder problems (cholecystitis).
- Inflammation of the appendix (appendicitis).
- Kidney stones.
- Kidney disease (pyelonephritis or chronic kidney disease).
- Urinary problems, such as a urinary tract infection (UTI).
- Bowel problems, such as a bowel obstruction.
- Infection in or around the brain, such as meningitis, encephalitis, or a brain tumor.
- Infection of the pelvic organs (pelvic inflammatory disease).
Nausea and vomiting can quickly cause dehydration. Older adults have an increased chance of becoming dehydrated because they may:
- Not drink because they do not feel as thirsty as younger people.
- Have kidneys that do not work well.
- Choose to not drink because of the inability to control their bladders (incontinence).
- Have physical problems or a
disease which makes it:
- Hard to drink or hold a glass.
- Painful to get up from a chair.
- Painful or exhausting to go to the bathroom.
- Difficult to talk or communicate to someone about their symptoms.
- Take medicines that increase urine output.
- Not have enough money to adequately feed themselves.
