Clinician’s Corner: Nausea of Pregnancy

Often referred to as “morning sickness” 75-80% of pregnant patients complain of morning or evening nausea. The peak time for morning sickness is in the first trimester between weeks 5-12 of pregnancy. Most women experience this discomfort, and by adjusting diet or routines, have minimal difficulty as resolution occurs at the beginning of the second trimester.

Hyperemesis gravidarum – the worst kind of morning sickness: 15% of pregnancies experience nausea and vomiting until delivery. Persistent vomiting to cause weight loss, dehydration and electrolyte imbalance.

The exact cause of nausea and vomiting during pregnancy is unknown. Elevated levels of human chorionic gonadotropin produced by the placenta is believed to play a part.  High-fat diets and Helicobacter pylori infection (which causes stomach ulcers) also contributes to the incidence and severity of hyperemesis gravidarum.

  • Reassurance and dietary advice is all that is required in most instances.
  • Place patient on “dry diet” plus clear liquids 1 hour after eating.
  • Get plenty of rest.
  • Avoid smells that bother you.
  • Eat five or six small meals each day instead of three large meals.
  • Eat a few crackers before you get out of bed in the morning to help settle your stomach.
  • Eat small snacks high in protein (such as a glass of milk or a cup of yogurt) throughout the day.
  • Avoid spicy foods and fatty foods.

First line (always weigh risks versus benefits).
