On top of dealing with hyperemesis symptoms, HG can also increase the risk of other conditions in pregnancy. Below is some information on these, how to recognise them, and how to get treatment. For most of these, the best way to reduce your risk is to get the correct treatment for HG. 

Thombosis/VTE

The risk of blood clots increases in pregnancy and afterwards, and is the most common cause of death in pregnancy and postnatally in the UK and Ireland (MBRRACE report 2024). 

Dehydration and immobility - not being able to leave bed or the couch for most of the day - increases this risk.

What can you do? 

• Tell your doctor if you are not able to leave bed/home due to your symptoms.
• Ask your medical team about assessing your risk and if so, if they have taken hyperemesis into account. This is particularly important if you have had blood clots before or if you have had Covid recently. 
• Your risk should be re-assessed throughout your pregnancy as your HG symptoms change.
• You may need to do additional things to reduce your risk, such as wearing compression stockings or taking anti-clotting medications.
