While most women suffer from morning sickness, also known as pregnancy-induced nausea, a small percentage of women, about 0.5 to 2 percent, can develop Hyperemesis Gravidarum. This condition is a serious medical problem that can lead to dehydration, weight loss, nutritional deficiencies, electrolyte imbalance, and/or physical and emotional stress. Severe and often constant vomiting usually shows up between 4-7 weeks of pregnancy, and symptoms can interfere with your regular activities.
If you are having severe nausea or suffering from regular vomiting that is preventing you from keeping fluids and food down, you should contact your caregiver to see if there is any potential help for your symptoms. If the condition goes on for a prolonged period without treatment, it can potentially be harmful to your pregnancy. The condition usually dissipates around week 20.
