Uncomplicated nausea may be treated with dry foods such as crackers and small, frequent meals. Emotional support may also help with nausea and/or vomiting.

It is important for a pregnant woman to maintain her fluid intake. Fluids should be emphasized during the times of the day when she feels least nauseated. Seltzer or other sparkling waters may be helpful.

Medication to prevent nausea is reserved for cases where vomiting is persistent and severe enough to present potential maternal and fetal risks. The most severe cases may require hospitalization with IV fluid administration.

An evaluation to rule out abnormalities of the liver or gastrointestinal tract may be necessary in cases of persistent symptoms.

Psychosocial support is an important part of treatment -- most nausea and vomiting during pregnancy is normal, although unpleasant.

Nausea and vomiting usually peaks between 2 and 12 weeks gestation and resolves by the second half of a pregnancy. With adequate identification of symptoms and careful follow-up, this sickness rarely presents serious complications for the infant or mother.

Social or psychological problems may be associated with this disorder of pregnancy. If such problems exist, they need to be identified and addressed appropriately.

Call your health care provider if you are pregnant and are experiencing severe nausea with vomiting.
