How do you prepare for Hyperemesis Gravidarum? HG Prep!

Although no one can say for sure if hyperemesis gravidarum (HG) will recur with every pregnancy, it does in over 75% of HG survivors. If you have a family member who had HG, you are very likely to have HG with every pregnancy but the severity may vary each time. Sometimes HG only occurs with multiple babies or first pregnancies. Effective and proactive care also affects how sick a person will become.

Our HGprep pages help to guide you through planning for an HG pregnancy

  • Mentallytreat and/or heal from past trauma and struggles.
  • Physically: prepare and be as strong as possible, including replenishing/rebuilding vitamin stores
  • Medicallyestablish a treatment plan (HG protocol) with the treating provider.
  • Sociallyplan support and help from friends and extended family.
  • Familycreate plans for older children and strengthen relationships.
  • Home: get organized and find help to maintain the home during pregnancy.
  • Financial: save as much money as you can to help with medical expenses, home expenses, and in case of job loss.

Question 1: "What can I do to prevent HG?"

The HER Foundation has discovered a genetic cause of HG, GDF15, but a cure or a way to prevent the associated hormone from rising and causing HG is unknown. HER is working on it! We believe the sicker you are, the more GDF15 increases, so early care is essential. Support our work so we can have a treatment for our daughters!

Question 2: "What can I take before pregnancy to help HG?"

While we don't know of anything to prevent HG, we know that having adequate amounts of key vitamins like B1/thiamin may reduce severity somewhat. Taking medications before HG starts does not prevent or lessen HG. Taking medications as soon as HG starts, however, can help reduce severity.

Question 3: "What lab tests or treatments will help before pregnancy?"

It's a good idea to have blood work and a full check-up before pregnancy. Ask about testing for thyroid and helicobacter pylori, especially if you have symptoms. A nutritional evaluation may be beneficial.

I truly never would have tried for a second baby if it wasn't for the HER Foundation. The immense research and resources they have provided were invaluable in getting proper health care during pregnancy
