I now have enough comprehensive information from Harrison's Principles of Internal Medicine and other textbooks to write a thorough answer. Let me compose the full Marathi-English mixed response.
🩺 HYPERTENSION (उच्च रक्तदाब) ⭐⭐⭐
📌 DEFINITION (व्याख्या)
Hypertension म्हणजे रक्तवाहिन्यांमध्ये रक्ताचा दाब सतत वाढलेला असणे.
ACC/AHA 2017 Guidelines नुसार:
- Normal BP: < 120/80 mmHg
- Elevated BP: 120-129 / < 80 mmHg
- Stage 1 HTN: 130-139 / 80-89 mmHg
- Stage 2 HTN: ≥ 140 / ≥ 90 mmHg
- Hypertensive Crisis: > 180 / > 120 mmHg
थोडक्यात: Systolic BP ≥ 130 mmHg किंवा Diastolic BP ≥ 80 mmHg असल्यास Hypertension म्हणतात.
Hypertension हे CVD (cardiovascular disease), Stroke, Heart Failure, CKD, आणि Dementia साठी major risk factor आहे.
🔍 ETIOLOGICAL FACTORS (कारणे)
1. PRIMARY / ESSENTIAL HYPERTENSION (95% cases)
कोणतेही एकच कारण नाही - multiple factors एकत्र असतात:
| घटक | तपशील |
|---|---|
| Genetic factors | Family history असल्यास risk जास्त |
| Sodium retention | Kidney sodium excrete करण्यास कमी पडते → BP वाढते |
| RAAS activation | Renin-Angiotensin-Aldosterone System overactive → Vasoconstriction |
| Sympathetic overactivity | Stress मुळे sympathetic system सतत active राहते |
| Endothelial dysfunction | Nitric oxide कमी → Vasodilation कमी होते |
| Obesity / Sedentary life | Visceral fat → Insulin resistance → HTN |
| Age | वय वाढल्याने arterial stiffness वाढते |
| Alcohol & Smoking | Direct vascular damage + BP वाढवतात |
2. SECONDARY HYPERTENSION (5% cases)
ओळखण्यायोग्य कारण असते:
- Renal: Chronic Kidney Disease, Renovascular HTN (renal artery stenosis)
- Endocrine: Primary Aldosteronism, Pheochromocytoma, Cushing's Syndrome, Hyperthyroidism
- Obstructive Sleep Apnea (OSA)
- Drugs: OCP (oral contraceptives), NSAIDs, Steroids, Decongestants
- Coarctation of Aorta (aorta चे narrowing)
🔬 INVESTIGATIONS (तपासण्या)
Routine / Basic Investigations:
| तपासणी | उद्देश |
|---|---|
| BP मोजणे (Both arms, multiple readings) | Diagnosis confirm करणे |
| CBC | Anaemia तपासणे |
| Blood Sugar (FBS/PPBS) | Diabetes co-existing? |
| Lipid Profile | Dyslipidemia तपासणे |
| Serum Creatinine & BUN | Renal function |
| Serum Electrolytes (Na⁺, K⁺) | Aldosteronism शोधणे |
| Urine Routine & Micro | Proteinuria, hematuria - kidney damage? |
| Urine Albumin:Creatinine Ratio | Early nephropathy |
| ECG (12-lead) | LVH (Left Ventricular Hypertrophy) |
| Chest X-Ray | Cardiomegaly, aortic changes |
| Fundoscopy | Hypertensive Retinopathy ग्रेड |
Advanced / Special Investigations:
- Echocardiography - LVH, diastolic dysfunction
- Renal USG + Doppler - Renovascular HTN
- 24-hour Urine Catecholamines - Pheochromocytoma
- Plasma Aldosterone / Renin ratio - Primary Aldosteronism
- Sleep Study (Polysomnography) - OSA शोधण्यासाठी
- Ambulatory Blood Pressure Monitoring (ABPM) - White coat HTN vs. True HTN
💊 MEDICAL MANAGEMENT (औषध उपचार)
Step 1: Non-Pharmacological (Lifestyle Changes)
(सर्व patients ना पहिल्यांदा द्यायचे)
| उपाय | Effect on SBP |
|---|---|
| DASH Diet | ↓ ~5 mmHg |
| Sodium restriction (<2g/day) | ↓ 5-6 mmHg |
| Weight loss (per kg) | ↓ ~1 mmHg/kg |
| Regular Exercise (30 min/day) | ↓ 4-5 mmHg |
| Alcohol restriction | ↓ 3-4 mmHg |
| Smoking cessation | Overall CVD risk ↓ |
Step 2: Pharmacological Treatment
1st Line Drugs (निवडक औषधे):
| Drug Class | उदाहरण | विशेष उपयोग |
|---|---|---|
| Thiazide Diuretics | Hydrochlorothiazide, Chlorthalidone | सर्वसाधारण HTN, Black patients |
| ACE Inhibitors (ACEi) | Enalapril, Ramipril, Lisinopril | Diabetes + HTN, CKD |
| ARBs | Losartan, Telmisartan, Valsartan | ACEi cough असल्यास |
| Calcium Channel Blockers (CCB) | Amlodipine, Nifedipine | Elderly, Angina असल्यास |
| Beta Blockers | Metoprolol, Atenolol | CAD, Heart Failure असल्यास |
Compelling Indications (विशेष परिस्थिती):
| स्थिती | पसंतीचे औषध |
|---|---|
| Diabetes + HTN | ACEi / ARB (रेनल protection) |
| Heart Failure | ACEi + Beta Blocker + Diuretic |
| Post-MI | Beta Blocker + ACEi |
| CKD with proteinuria | ACEi / ARB |
| Pregnancy (PIH) | Methyldopa, Labetalol, Nifedipine |
| Hypertensive Emergency | IV Labetalol, IV Nitroprusside, IV Nicardipine |
Target BP:
- सामान्य रुग्ण: < 130/80 mmHg
- CKD / Diabetes: < 130/80 mmHg
- Elderly (>65 yr): < 130 mmHg SBP (with caution)
🥗 DIET & HEALTH EDUCATION (आहार आणि आरोग्य शिक्षण)
DASH Diet (Dietary Approaches to Stop Hypertension):
खावे (Recommended):
- ✅ भरपूर फळे व भाज्या (Fruits & Vegetables)
- ✅ Whole grains (गहू, ज्वारी, बाजरी, ओट्स)
- ✅ Low-fat dairy (दूध, दही - कमी फॅट)
- ✅ Lean proteins (मासे, डाळी, शेंगा)
- ✅ Nuts & Seeds (बदाम, अक्रोड)
टाळावे (Avoid):
- ❌ जास्त मीठ (Sodium < 2g/day - 1 चमचापेक्षा कमी)
- ❌ Saturated fats, Trans fats (Fried food, Bakery items)
- ❌ Red meat जास्त खाऊ नये
- ❌ Sugary drinks, Cold drinks
- ❌ Alcohol (पूर्णपणे बंद करणे उत्तम)
- ❌ Smoking / Tobacco पूर्णपणे बंद
📢 HEALTH EDUCATION (आरोग्य शिक्षण):
रुग्णाला सांगायच्या गोष्टी:
- BP नियमित तपासणे - घरी BP machine ठेवावे, record ठेवावा
- औषधे नियमित घेणे - कधीही बंद करू नका, बरे वाटले तरी चालू ठेवा
- वजन नियंत्रण - BMI 18.5-24.9 मध्ये ठेवावे
- व्यायाम - रोज किमान 30 मिनिटे (चालणे, पोहणे, सायकल)
- Stress management - Yoga, Meditation, खोल श्वास
- Compliance (Adherence) - Doctor सांगेल त्याप्रमाणे औषधे घेणे
- Follow-up - नियमित डॉक्टरांकडे जाणे, BP check करणे
- Danger signs माहीत असणे - डोकेदुखी, दृष्टी धूसर होणे, श्वास लागणे → लगेच Hospital
Target Organ Damage (गुंतागुंत) टाळणे:
- Heart: LVH → Heart Failure, MI
- Brain: Stroke, Hypertensive Encephalopathy
- Kidney: CKD, Proteinuria
- Eyes: Hypertensive Retinopathy
- Arteries: PAD, Aortic Aneurysm

🔑 Key Points (परीक्षेसाठी लक्षात ठेवा):
- HTN = BP ≥ 130/80 mmHg (ACC/AHA 2017)
- 95% cases = Essential / Primary HTN
- 1st Line drugs = Thiazide, ACEi/ARB, CCB, Beta Blocker
- DASH diet + Sodium restriction = Best non-pharmacological therapy
- "Silent Killer" - बरेचदा कोणतीही लक्षणे नसतात म्हणून नियमित BP तपासणे महत्वाचे
