Understanding Hyperemesis Gravidarum

Nausea and sickness in early pregnancy are very common, but for some people it becomes so intense that day to day life feels almost impossible. Hyperemesis gravidarum, often shortened to HG, is a term used to describe extreme sickness in pregnancy, and it can be physically and emotionally draining.

What Hyperemesis Gravidarum Is

Hyperemesis gravidarum is a severe form of pregnancy sickness where nausea and vomiting are much more intense than typical morning sickness. People with HG may be sick many times a day, struggle to keep food or fluids down, and feel constantly exhausted and unwell. It can affect work, caring responsibilities, and everyday tasks, and it is not something you can simply push through.

How It Differs from Usual Morning Sickness

Many pregnant people feel nauseous, especially in the first trimester, and may be sick occasionally. With HG:

• Sickness is frequent and sometimes continuous
• You may lose weight or struggle to drink enough
• Strong smells, movement, or simply getting up can trigger vomiting

If you feel unable to keep fluids down, are passing very little urine, or feel dizzy and weak, it is important to speak to a healthcare professional promptly.

Getting Support and Treatment

Although HG can feel very isolating, support is available. Healthcare professionals may suggest treatments such as anti sickness medication, fluids, or advice on small, frequent sips and snacks—MotherToBaby can provide guidance on medication safety during pregnancy. Needing help does not mean you are failing.

It can also be helpful to:

• Ask a partner, family member, or friend to advocate for you if speaking up feels hard
• Rest as much as possible and let go of non essential tasks
• Connect with others who have experienced HG through trusted support organisations like the HER Foundation

You Are Not Alone

Hyperemesis gravidarum is not your fault and not a sign that you are doing pregnancy wrong. It is a real, recognised condition, and asking for help is a strong and sensible step. If you are unsure whether what you are feeling counts as HG, trust your instincts and talk to a midwife, GP, or other healthcare professional.
