गर्भावस्था में उच्च रक्तचाप विकार: भारत में बढ़ती प्रचलन, जोखिम और प्रबंधन
उच्च रक्तचाप विकार 7.8‑11% भारतीय गर्भधारणाओं को प्रभावित करते हैं, जिससे वे मातृ और नवजात जटिलताओं के प्रमुख कारण बनते हैं। प्रारंभिक पहचान, जोखिम‑आधारित स्क्रीनिंग, और निवारक कम‑खुराक एस्पिरिन रोगभार को कम करने और UPSC स्वास्थ्य‑नीति प्राथमिकताओं के साथ संरेखित करने के लिए महत्वपूर्ण हैं।
Overview Hypertensive disorders of pregnancy remain a leading cause of maternal and foetal morbidity worldwide. In India, the prevalence is estimated at 7.8‑11% , placing the country among the highest globally. The conditions range from gestational hypertension to the severe forms of pre‑eclampsia and eclampsia . Early detection and systematic monitoring are essential to curb the associated complications. Key Developments Global estimates from the WHO indicate that hypertensive disorders affect 5‑10% of all pregnancies. Risk factors identified include obesity, diabetes, chronic kidney disease, thyroid disorders, pre‑existing hypertension, first‑time pregnancy, twin gestations, and advanced maternal age (>40 years). Complications span maternal eclampsia, stroke, acute kidney injury, pulmonary edema, liver dysfunction, placental abruption, and increased cesarean deliveries; foetal outcomes include growth restriction, preterm birth, low birth weight and higher perinatal mortality. Screening protocols now recommend first‑trimester risk assessment and, for high‑risk women, initiation of aspirin prophylaxis to mitigate pre‑eclampsia risk. Important Facts • Pre‑eclampsia alone affects 3‑8% of pregnancies globally (WHO). • Chronic hypertension with superimposed pre‑eclampsia constitutes a high‑risk subgroup. • Maternal mortality from hypertensive disorders remains among the top causes worldwide, underscoring the need for robust antenatal care. • Women who experience hypertensive disorders in pregnancy have a higher lifetime risk of chronic hypertension, ischemic heart disease, and stroke. UPSC Relevance The topic cuts across multiple GS papers: GS3 (Health) – understanding disease burden, preventive strategies, and health‑system response; GS4 (Ethics) – addressing equity in maternal health

Key Insight
Rising Hypertensive Disorders in Pregnancy Threaten India’s Maternal Health Targets
Key Facts
- Hypertensive disorders affect 7.8‑11% of pregnancies in India (2026), among the highest globally.
- WHO estimates 5‑10% of all pregnancies worldwide have hypertensive disorders; pre‑eclampsia alone 3‑8%.
- Key risk factors: obesity, diabetes, chronic kidney disease, thyroid disorders, pre‑existing hypertension, first pregnancy, twin gestation, and maternal age >40 years.
- Complications include maternal eclampsia, stroke, acute kidney injury, pulmonary edema, liver dysfunction, placental abruption; fetal outcomes: IUGR, preterm birth, low birth weight, higher perinatal mortality.
- National guidelines (2026) recommend first‑trimester risk assessment and low‑dose aspirin (75‑150 mg) for high‑risk women to prevent pre‑eclampsia.
- Magnesium sulphate is the drug of choice for preventing and treating eclampsia as per WHO and Indian obstetric protocols.
- Maternal deaths from hypertensive disorders remain in the top five causes of maternal mortality in India, hindering achievement of SDG‑3 targets.
Background
Hypertensive disorders of pregnancy (HDP) are a major public‑health challenge, intersecting GS3 (Health) and GS1 (Socio‑Economic Development) by affecting maternal mortality, neonatal outcomes, and broader development indicators. The rising prevalence underscores gaps in antenatal care, risk‑assessment mechanisms, and implementation of WHO‑endorsed preventive measures such as low‑dose aspirin.

Mains Angle
In a Mains answer, candidates can address HDP under GS3 (Health), analysing policy gaps, programme effectiveness (e.g., RMNCH+A), and constitutional obligations under Article 21 to ensure the right to health for pregnant women.
