What are the two most common complications of hyperemesis gravidarum?

In hyperemesis gravidarum, the two most common complications are indeed electrolyte imbalance and starvation. This condition is characterized by severe nausea and vomiting during pregnancy, which can lead to significant loss of fluids and essential electrolytes, such as sodium, potassium, and chloride. As a result, the body's electrolyte levels can become severely disrupted. This imbalance can lead to complications such as cardiac arrhythmias or muscle weakness.

Starvation occurs because the excessive vomiting prevents adequate nutrient intake. When the body is unable to retain food, it begins to utilize its energy reserves, which can lead to weight loss and malnutrition. Therefore, electrolyte imbalance is a direct consequence of fluid loss, and starvation signifies the body's inability to receive the necessary nourishment.

While dehydration is an important concern, the primary issues stemming from hyperemesis gravidarum revolve around the impacts on electrolyte levels and nutritional sufficiency, making the mentioned complications highly relevant in this context.
