Can morning sickness and other forms of GI distress be relieved?

Although some expectant mothers never experience it, morning sickness is common and does not necessarily occur only in the morning. Feelings of nausea may be relieved by eating low-fat, easily digested carbohydrate foods, such as dry toast, plain crackers, cereal, pasta, rice, or fruit.

For nausea and vomiting, small, frequent meals tend to be tolerated better than large ones. Fried, gas-forming, or spicy foods may cause discomfort. Fluids often are better tolerated between meals rather than with them. A snack before getting up or bedtime may help. If the problem persists or becomes severe, the woman should seek advice from her health professional. Constipation also can be a problem and may partially result from decreased intestinal motility, characteristic of the second and third trimesters. Foods high in insoluble fiber, such as fresh fruits and vegetables and whole grain breads and cereal, can help alleviate constipation. Liberal consumption of fluids and a regular pattern of moderate physical activity also can help. Iron supplements may promote constipation, especially if fiber intake is low; check the dosage. Unless advised by a health care provider, laxatives are best avoided.
