Mild gestational hypertension: what to know

The condition usually begins after the middle of pregnancy. It may cause no noticeable symptoms, which is why blood pressure readings and urine checks matter even when you feel well. Your maternity team may also ask about headache, vision changes, upper abdominal pain, swelling that appears suddenly, and changes in your baby's movements. A diagnosis does not automatically mean that labour needs to start immediately; the plan depends on your readings, examination, pregnancy stage, and the baby's wellbeing.

Keep every antenatal appointment and take any prescribed medicine exactly as directed. If you are checking at home, sit quietly first, use the recommended device and position, and record the reading with the time and any symptoms. Do not change treatment or restrict food and fluids without advice. Rest when possible, remain alert to your baby's usual movements, and bring your record to appointments. Your clinician may arrange extra blood tests, urine checks, blood pressure reviews, or ultrasound monitoring.

Contact your maternity unit promptly for a severe or persistent headache, blurred vision or flashing lights, pain beneath the ribs, sudden breathlessness, sudden facial or hand swelling, vomiting that feels unusual, vaginal bleeding, or reduced baby movements. Seek urgent help for severe breathing difficulty, a seizure, collapse, or heavy bleeding. Do not wait for the next appointment if symptoms are new or worsening.

Ask how often your blood pressure should be checked, which reading or symptom should trigger a call, whether urine and blood tests are planned, how the baby's growth will be followed, and how the timing and mode of birth may change if readings rise.
