Diagnosing gestational hypertension: what to know

A clinician measures your blood pressure using a correctly sized cuff and may repeat the reading after rest. Urine testing can look for protein, while blood tests may assess the liver, kidneys and blood cells. Your symptoms, pregnancy stage and the baby’s wellbeing are considered alongside the readings. Gestational hypertension differs from pre-eclampsia when there is no evidence of organ involvement, but it can change over time and needs follow-up.

Keep every antenatal appointment and take prescribed medicine exactly as directed. Your maternity team may ask you to record readings at home, attend repeat checks, or have ultrasound and monitoring of the baby’s growth and wellbeing. Bring your home monitor to an appointment if possible so its technique can be checked. Antenatal care provides a structured way to review blood pressure and plan delivery safely.

Contact your maternity unit urgently for a severe or persistent headache, visual changes, pain beneath the ribs, sudden swelling of the face or hands, shortness of breath, heavy bleeding, or noticeably reduced baby movements. Do not wait for a routine appointment if these symptoms appear; they can signal a pregnancy complication requiring prompt assessment.

Ask which readings led to the diagnosis, how often your blood pressure and urine should be checked, which symptoms warrant immediate help, and how the baby will be monitored. You can also ask whether any medicines, activity changes or delivery planning apply to your situation.
