How common is severe headache in pregnancy in gestational hypertension?

Gestational hypertension means high blood pressure developing during pregnancy. A severe headache may occur as blood pressure rises, but headache can also result from dehydration, migraine, infection, lack of sleep, or other causes. The symptom alone cannot identify the cause, so a clinician may check your blood pressure, urine, symptoms, and overall wellbeing.

Tell the clinician whether the headache improves with rest, fluids, or approved medicine, and whether you have visual changes, pain beneath the ribs, swelling, nausea, or breathlessness. Those details help determine how quickly you need review.

Call your maternity team promptly about a severe headache in pregnancy, especially if it does not settle or keeps returning. Rest in a quiet place, drink fluids if you can, and use only medication approved for you during pregnancy. Check your blood pressure if your care team has given you a monitor and instructions, but do not rely on a home reading to dismiss serious symptoms.

Seek urgent maternity or emergency care for a sudden severe headache, headache with blurred or flashing vision, confusion, weakness, difficulty speaking, a seizure, chest pain, shortness of breath, severe abdominal pain, or fainting. Get prompt help if you cannot keep fluids down or feel substantially worse. These signs require examination and monitoring.

Ask your clinician: What is my blood pressure and does it need repeat checks? Should I provide a urine sample or have blood tests? Which headache treatments are suitable for me? What number or symptom should trigger an immediate call, and where should I go after hours?
