3-Step Workflow: From Clinical Input to Actionable Pakistani Guidance
Choose a South Asian Clinical Tool
Pick from metabolic (BMI, Waist-to-Height, Calorie/Macro, HbA1c), paediatric (Calpol/Brufen Dose, WHO ORS Fluid, EPI Schedule, Growth Percentile), or environmental (Lahore/Karachi AQI Smog, Heatstroke Risk) tools.
Enter Values or Click “Try Demo Sample”
Test any calculator with one click using realistic Pakistani clinical presets, or enter your exact weight, age, lab result, or local suspension strength (e.g., 120 mg/5 mL vs 250 mg/5 mL).
Review Citation-Backed Thresholds & Red Flags
Every result displays the exact formula used (WHO, BNFc, CKD-EPI 2021, ACC/AHA, IDF-DAR), emergency warning signs, and direct links to relevant Pakistani medicine monographs.

Frequently Asked Questions — Pakistan Health Calculators
Why do Pakistani adults need South Asian BMI and waist cutoffs instead of Western calculators?
Under the WHO Expert Consultation on Asian Populations, South Asians accumulate higher visceral (abdominal) fat and develop insulin resistance, type 2 diabetes, and coronary artery disease at lower BMI values than European populations. A healthy South Asian BMI is 18.5–22.9 kg/m², overweight begins at 23.0 kg/m² (vs 25.0 globally), and obesity begins at 27.5 kg/m² (vs 30.0 globally).
Are PakVita health calculators free and private?
Yes. Every calculator on PakVita runs 100% client-side in your browser with zero signup, zero email gates, and zero server-side storage of your personal health inputs. Each calculator also includes a one-click 'Try Demo Sample' preset so you can test the formula immediately.
Which clinical guidelines power PakVita's paediatric and renal calculators?
Our Paediatric Dose Calculator uses BNF for Children (BNFc) and WHO Model Formulary weight-based rules (15 mg/kg/dose for paracetamol, 5–10 mg/kg/dose for ibuprofen). Our ORS & Dehydration Calculator follows WHO/UNICEF Integrated Management of Childhood Illness (IMCI) Plan A and Plan B (75 mL/kg over 4 hours). Our eGFR Calculator implements the race-free 2021 CKD-EPI creatinine equation with KDIGO staging.
Does the Calorie & Macro Calculator include real Pakistani household foods?
Yes. Unlike US/UK food trackers that lack South Asian staples, PakVita's Calorie & Macro Calculator includes a built-in nutrition table for 31 everyday Pakistani foods — including whole-wheat chapati/roti, paratha, naan, chicken biryani, masoor/chana/moong daal, nihari, dahi, lassi, and doodh patti chai.
How does the Ramadan Medication Planner handle diabetes and blood pressure medicines?
It maps once-daily, twice-daily, and three-times-daily regimens onto Sehri (pre-dawn) and Iftar (sunset) windows while flagging high-hypoglycaemia-risk drug classes (such as sulfonylureas and premixed insulins) using International Diabetes Federation and Diabetes & Ramadan (IDF-DAR) risk-stratification guidelines.
