Frequently asked questions
What is considered low blood pressure?+
A reading below 90/60 mmHg is generally classed as low (hypotension). Many people with naturally low BP feel fine and need no treatment — what matters is whether it causes symptoms like dizziness or fainting.
When is low blood pressure dangerous?+
Seek medical care if low BP comes with fainting, confusion, blurred vision, a weak rapid pulse, cold clammy skin, or breathlessness — these can signal dehydration, blood loss, infection, or a heart or hormonal problem. Sudden low BP after starting a new medication also needs review.
What is a normal blood pressure reading for Indian adults?+
Under 120/80 mmHg is normal. 120–129/under 80 is elevated. 130–139/80–89 is Stage 1 hypertension. 140/90 or above is Stage 2 hypertension. Above 180/120 is a hypertensive crisis — seek emergency care. These thresholds follow JNC8 and Indian Society of Hypertension guidance.
How accurate is a home BP monitor?+
Validated upper-arm digital monitors (Omron, Microlife, Beurer) are accurate to within ±3 mmHg when used correctly. Wrist monitors are less reliable. Take 2–3 readings a minute apart while seated quietly with feet flat — the average is your real reading.
What's the difference between systolic and diastolic blood pressure?+
Systolic (the top number) is the pressure when your heart contracts. Diastolic (the bottom number) is the pressure when your heart relaxes between beats. In adults over 50, systolic is generally the more important predictor of heart-disease and stroke risk.
When should I see a doctor about my BP?+
See a doctor if your reading is consistently 140/90+ across days, is 180/120+ (urgent), comes with chest pain, severe headache, vision changes or breathlessness, or is 130/80+ when you have diabetes or kidney disease. PingMeDoc can connect you with a doctor for teleconsultation.
