O13.3
Gestational [pregnancy-induced] hypertension without significant proteinuria, third trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Gestational hypertension without proteinuria, classified under ICD-10 code O13.3, is a condition characterized by elevated blood pressure that occurs during the third trimester of pregnancy. Unlike preeclampsia, this form of hypertension does not involve significant protein in the urine. Managing this condition is crucial to ensure the health and safety of both mother and baby, but it is often less severe than other pregnancy-related hypertensive disorders. Early recognition and regular monitoring are key components of care.
Causes & Symptoms
Clinical Causes: Genetic predisposition to high blood pressure Pre-existing hypertension that develops during pregnancy Hormonal changes affecting blood vessel tone Placental abnormalities leading to vascular resistance Lifestyle factors such as stress, poor diet, and lack of physical activity Certain medical conditions predisposing to hypertension
Key Symptoms: Elevated blood pressure readings, typically above 140/90 mm Hg Headaches, especially severe or persistent ones Visual disturbances like blurred vision or spots Swelling in the hands, face, or legs (less common in this condition) Dizziness or lightheadedness Fatigue or feeling of overall discomfort
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves regular blood pressure measurements during prenatal visits, especially in the third trimester. Healthcare providers may perform additional tests including blood tests, urine tests, and fetal monitoring to rule out other complications. The key criteria include sustained high blood pressure without significant protein in the urine. In some cases, additional assessments help differentiate gestational hypertension from preeclampsia or other hypertensive disorders during pregnancy.
Treatment Protocols: Management focuses on controlling blood pressure and monitoring the pregnancy closely. Approaches include:
