Hyperemesis Gravidarum

Its been a long road, and its comforting to find people's blogs or stories about women who have had this condition and learning about how people cope, and how I can better cope with the emotional stress along with all the physical stress. Like most medical conditions, you never really learn about it until it effects you or someone you know. I thought I would share some of what I have learned...

What Is Hyperemesis Gravidarum?

HG is a debilitating and potentially life-threatening pregnancy disease marked by rapid weight loss, malnutrition, and dehydration due to unrelenting nausea and/or vomiting with potential adverse consequences for the newborn(s).

Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy. It is generally described as unrelenting, excessive pregnancy-related nausea and/or vomiting that prevents adequate intake of food and fluids. If severe and/or inadequately treated, it is typically associated with:

• loss of greater than 5% of pre-pregnancy body weight (usually over 10%)
• dehydration and production of ketones
• nutritional deficiencies
• metabolic imbalances
• difficulty with daily activities

HG usually extends beyond the first trimester and may resolve by 21 weeks; however, it can last the entire pregnancy in less than half of these women. Complications of vomiting (e.g. gastric ulcers, esophageal bleeding, malnutrition, etc.) may also contribute to and worsen ongoing nausea.

There are numerous theories regarding the etiology of hyperemesis gravidarum. Unfortunately, HG is not fully understood and conclusive research on its potential cause is rare. New theories and findings emerge every year, substantiating that it is a complex physiological disease likely caused by multiple factors.

Diagnosis is usually made by measuring weight loss, checking for ketones, and assessing the overall condition of the mother. If she meets the standard criteria and is having difficulty performing her daily activities, medications and/or other treatments are typically offered.

Treating HG is very challenging and early intervention is critical. HG is a multifaceted disease that should be approached with a broad view of possible etiologies and complications. When treating mothers with HG, preventing and correcting nutritional deficiencies is a high priority to promote a healthy outcome for mother and child.

The list of potential complications due to repeated vomiting or severe nausea is extensive, all of which may worsen symptoms. Common complications from nausea and vomiting include debilitating fatigue, gastric irritation, ketosis, and malnutrition. Aggressive care early in pregnancy is very important to prevent these and more life-threatening complications such as central pontine myolinolysis or Wernicke's encephalopathy.
