Amenorrhea due to normal causes, such as pregnancy, does not need to be treated. In other cases, treatments will depend on the cause. Treatments include:
Dieting and exercising to lose weight (for amenorrhea caused by obesity)
Dieting to gain weight (for amenorrhea caused by extreme weight loss)
Learning ways to manage stress
Changing exercise levels
Hormones, ordered by a health care provider
Surgery (rarely)
Amenorrhea may be the symptom of anorexia nervosa, a serious eating disorder. If you or someone you care about has this condition, get help right away
The timing of the nausea or vomiting can indicate the cause. When it appears shortly after a meal, nausea or vomiting may indicate a mental disorder or a peptic ulcer. Nausea or vomiting one to eight hours after a meal may indicate food poisoning. Foodborne diseases, such as Salmonella, may take longer to produce symptoms because of the incubation time.
A person who is experiencing nausea should consult a physician if it lasts more than one week, and if there is a possibility of pregnancy. Vomiting usually subsides within 6 to 24 hours, and may be treated at home.
You should see your doctor if home treatment is not working, dehydration is present, or a known injury (such as head injury or infection) is causing the vomiting.
