What is the hypertension in pregnancy (HiP) clinic?
Based at St Thomas’ Hospital, the hypertension in pregnancy (HiP) clinic provides specialist obstetric and midwifery care to pregnant women with high blood pressure (hypertension) and women who are at high risk of having high blood pressure in pregnancy.
We want to improve your care by providing support, treatment and information during and after your pregnancy.
The HiP clinic team also aims to improve your care by providing guidance to hospital and community staff – see ‘Information for health care professionals’ below.
Information for women with hypertension in pregnancy
High blood pressure affects about one in ten pregnancies. You have been asked to come to the clinic because you already have high blood pressure or you have a higher risk of having blood pressure problems in your pregnancy.
Why you would be asked to see us
You may have been asked to see us because you have:
- an existing medical condition that means you are more likely to get high blood pressure
- high blood pressure diagnosed early in pregnancy
- protein in your urine or other kidney problems in this pregnancy.
What will happen at your appointment
At your appointments we will:
- ask you how you are feeling
- check on your baby’s well-being
- measure your blood pressure
- measure the protein in your urine
- take blood tests to check how your kidneys, liver and blood are working.
These tests help us to check that you and your baby are safe. We might recommend you have other tests or treatment.
At the HiP clinic we will get to know your individual needs. If your blood pressure is high, you will usually need to take tablets to treat it. We will work with you to plan your care and any treatment you need to keep you and your baby safe. The leaflets below give more information.
