Hyperemesis Gravidarum

Nutrition & Health

Pregnancy is not always smooth sailing for some women especially for those that suffer from Hyperemesis Gravidarum (HG) during much of their pregnancy.

Hyperemesis Gravidarum is a severe form of morning sickness that affects around 0.3-2% of pregnancies. Unlike typical morning sickness, which involves mild nausea and vomiting, HG is characterized by relentless, excessive vomiting and nausea that can lead to hospitalisation to treat severe dehydration and malnutrition.

  • Other symptoms of HG also include:
  • weight loss,
  • Sensitivity to certain smells and tastes, and
  • electrolyte imbalances.

While the exact cause is not fully understood, hormonal changes and other factors likely contribute to the development of HG.

The toll that HG takes on both physical and mental well-being cannot be underestimated. Everyday tasks become monumental challenges, and the prospect of nourishing both the baby and the mother become a delicate balancing act.

However, one of the most critical aspects of dealing with HG is having a strong support system and practicing self-care and staying well hydrated. Friends, family, and healthcare providers play a vital role in providing empathy, emotional and mental support and practical assistance that can all make a significant difference. Education about HG can help loved ones understand the challenges faced by pregnant individuals and provide the necessary support.
