Nausea and vomiting during pregnancy.
What is it? (Overview)
If you are spending most mornings in the bathroom feeling queasy, you are not alone. As many as 90% of all pregnant women experience some symptoms of morning sickness, while one-third actually vomit due to this condition. It usually begins four to six weeks after conception and continues until the 14th to 16th week of gestation. The exact cause of morning sickness is unknown, but several theories exist. Most experts believe it’s triggered by hormonal changes, especially the increase in hCG (human chorionic gonadotrophin). High levels of this pregnancy hormone are thought to over stimulate the part of the brain that controls nausea and vomiting. Gall bladder disease, hyperactive thyroid, molar pregnancy, or carrying more than one baby may also cause morning sickness. Other possible culprits include the physical symptoms of pregnancy: an enhanced sense of smell, stretching of the uterine muscles, displacement of the digestive organs, and excess acid in the stomach. Emotional stress and a high-fat diet may also ply a part.
How do I know I have it? (Symptoms and Diagnosis)
As the name suggests, most women experience morning sickness in the early hours of the day. It can occur at any time, and for some women, it even lasts all day. It generally consists of nausea and vomiting, but may also include dizziness and headaches.
- Eat a diet high in protein and complex carbohydrates. Try peanut butter or apple slices or celery; nuts; cheese and crackers; and milk, cottage cheese, and yogurt. Bland foods like gelatin, frozen desserts, broth, ginger ale, and saltine crackers also soothe the stomach.
- Avoid eating fatty foods. Recent research suggests that a high-fat diet contributes to morning sickness.
- Keep your blood sugar even by eating and drinking small portions frequently. Try eating before getting hungry and before nausea strikes.
- Keep crackers by the bed and eat one or two before getting up for the day.
- Drink plenty of liquid. Try to drink between meals rather than with meals to prevent your stomach from getting too full.
- Take vitamin supplements at night, as the iron they contain may irritate your stomach. You may have to try several prenatal vitamins before finding one you can tolerate.
- Keep morning activities slow and calm.
- Avoid staying in poorly ventilated spaces that trap food or other odors.
- Avoid smoking cigarettes.
- Get extra sleep and try to minimize stress as much as possible.
- Use acupressure wristbands. These apply pressure to specific points on the wrist, and are often used to ease motion sickness. You can find them at drug stores, and travel stores.
- Try acupuncture. Some acupuncturists are specially trained to work with pregnant women. Talk t your health-care provider before consulting a licensed acupuncturist.
- Take 100 to 200 milligrams of vitamin B supplements daily, especially B6.
Contact your health-care provider if:
- Morning sickness does not improve, despite trying home remedies.
- You are vomiting blood or material that looks like coffee grounds.
- There is prolonged, severe vomiting for three or more days, which can cause dehydration and malnutrition.
