What Are the Symptoms of Gestational Hypertension?

Pregnancy-induced hypertension (PIH) manifests with symptoms including abnormally elevated blood pressure, pronounced edema, dizziness and headache, visual disturbances, and changes in proteinuria levels. This condition poses serious risks to both maternal and fetal health. If severe headache, blurred vision, or persistent upper abdominal pain occurs, immediate medical evaluation and treatment are essential.

1. Abnormally Elevated Blood Pressure: Blood pressure readings during pregnancy exceed normal ranges, with either systolic or diastolic pressure showing sustained elevation. Some pregnant women experience no obvious symptoms and only discover the abnormality during routine prenatal checkups. Persistent hypertension increases systemic vascular stress.

2. Pronounced Edema: Swelling commonly appears in the ankles and lower legs, and may progress to involve the face and hands in severe cases. Edema does not resolve spontaneously with rest, reflecting abnormal interstitial fluid metabolism—a common clinical sign indicating disease progression.

3. Dizziness and Headache: A persistent sensation of head heaviness or pressure is frequently reported, often localized to the temples or occipital region. Discomfort persists despite rest and tends to worsen following emotional stress or physical fatigue.

4. Visual Disturbances: Symptoms include blurred or double vision, scintillations (flashing lights), or floating dark spots. These result from retinal vascular changes and indicate significant disease progression—prompt medical attention is critical to prevent further systemic complications.

5. Altered Proteinuria: Urinalysis reveals increased urinary protein excretion, reflecting impaired glomerular filtration function. Excessively foamy urine that persists for prolonged periods signals renal involvement, which may subsequently compromise overall maternal health.

For daily management: ensure adequate rest, preferably in the left lateral decubitus position; maintain a light, low-sodium diet; monitor blood pressure regularly; adhere strictly to scheduled prenatal visits; and closely observe both maternal well-being and fetal development.
