High Blood Pressure: What Your Reading Means, Why It Climbs in Winter, and What to Do Next

The machine at the pharmacy says 148/94. Or the office health camp writes 152/96 on a slip and says "get it checked". You feel completely well. So is it real, or was it the stairs, the tea, the traffic?

It might be either. A single high reading is not a diagnosis, and feeling well is not proof of normal blood pressure. Most people with high blood pressure feel nothing at all, which is why it is worth one proper check rather than a guess.

What the two numbers mean

Blood pressure is the force of blood pushing on the walls of your arteries. It is written as two numbers:

- The top number (systolic) is the pressure when the heart squeezes.

- The bottom number (diastolic) is the pressure when the heart relaxes between beats.

Both numbers count; either one being high is enough. Pressure that stays high for years strains the heart, the kidneys, the blood vessels in the brain and the back of the eye, quietly, which is why the number matters even when you feel fine.

What counts as high

These are the cut-offs most doctors in India and the UK work with:

| Reading | What it usually means |

|---|---|

| Below 120/80 | In the ideal range |

| 120 to 139 over 80 to 89 | Higher than ideal. Not high blood pressure by these cut-offs, but worth rechecking and worth acting on |

| 140/90 or above at the clinic, on more than one occasion | High blood pressure |

| 135/85 or above, as an average of readings taken at home | High blood pressure |

| 180/120 or above | Very high. Read the hospital section below |

The home cut-off is lower because many people's pressure rises in a doctor's room and settles in their own chair. American guidelines draw the line lower still, at 130/80, which is why you may read different numbers in different places. Your doctor will weigh your other risks, not only the cut-off.

How common this is in India

Very. The ICMR-INDIAB study, published in The Lancet Diabetes & Endocrinology in 2023 and covering more than 113,000 adults, found high blood pressure in 35.5% of Indian adults, roughly one in three. The national screening programme checks every adult from 30 years of age. If you are over 30 and cannot remember your last reading, it is time for one.

Your risk is higher with a parent or sibling who has it, extra weight around the middle, a salty diet, smoking, regular drinking, a desk-bound day, or diabetes or kidney disease.

Why readings climb in winter

Blood pressure follows the seasons. When it is cold, blood vessels narrow to hold in heat, and the pressure inside them rises. A 2021 review in Hypertension Research found that readings taken at home run on average about 6 points higher for the top number in winter than in summer.

For Delhi, that means the next few months, and winter adds less walking, heavier food and namkeen in every room through the festive season. If your reading was borderline in summer, check it again in December. If you already take blood pressure medicine, a winter check helps your doctor see whether the dose still fits. Do not change a dose yourself; bring your home readings and let the doctor decide.

Symptoms, in the words people actually use

Usually there are none. "I would feel it" is not true for most people. When people do notice something, they describe:

- "A heavy feeling at the back of my head in the morning"

- "My vision goes blurry for a few seconds"

- "My heart is pounding even when I am sitting still"

- "I get breathless climbing stairs that I used to manage easily"

These have many causes. They are a reason to get checked, not a way to tell whether your pressure is high. Only a measurement tells you that.

When to go to a hospital, not a clinic

Go to a hospital emergency department, or call 112, if a reading is 180/120 or above and you have any of these:

- Chest pain or tightness, or pain spreading to the arm, neck, jaw or back

- Breathlessness, especially at rest or when lying flat

- Sudden weakness or numbness in the face, an arm or a leg, a drooping face, or slurred speech

- Sudden blurred vision or loss of vision

- A severe headache unlike any you have had before, or confusion

- During pregnancy or soon after delivery: a severe headache, flashing lights or blurred vision, pain just below the ribs, vomiting, or sudden swelling of the face, hands or feet. These can be signs of pre-eclampsia

If a reading is 180/120 or above and you feel well, rest quietly and measure again. If it is still that high, call us the same day so a doctor can see you; do not wait for it to come down on its own.

Do not drive yourself to hospital. Take the strips of every medicine you take.

How to take a reading at home that you can trust

If your readings are borderline or high, a home monitor is worth buying. A few rules decide whether its number helps or misleads:

- Use an upper-arm cuff monitor, not a wrist or finger one, and check that the cuff fits your arm.

- No tea, coffee, cigarettes or exercise for 30 minutes before. Empty your bladder first.

- Sit on a dining chair, back supported, feet flat on the floor, and rest quietly for 5 minutes. No phone, no talking.

- Bare arm, resting on a table, with the cuff at the level of your heart.

- Take two readings, one minute apart, and write both down.

- Measure morning and evening for about a week before your appointment, at the same times each day.

Bring the list, or the monitor, to the consultation.

What actually helps

- Cut the salt. India's National NCD Monitoring Survey (2023) found that adults eat about 8 grams of salt a day; the World Health Organization recommends less than 5. In a Cochrane review, cutting about 4 grams a day lowered the top number by about 5 points in people with high blood pressure. Most of it hides in pickles, papad, namkeen, packaged snacks and restaurant food.

- Move for 150 minutes a week. A brisk 30-minute walk on five days is enough to count.

- Lose a little weight if you are carrying extra. Even a few kilograms helps.

- Drink less alcohol, and stop smoking.

- Eat more vegetables, fruit, dal and whole grains, and fewer fried and packaged foods.

- Keep the house warm in winter, especially first thing in the morning.

For some people these changes are enough. Many also need medicine, and that is not a failure. Take it every day, including the days you feel fine, and never stop a blood pressure medicine on your own. If you think a tablet is causing a problem, bring the strip and say so; there is usually an alternative.

What we will not do

- We will not diagnose high blood pressure from one reading. Unless it is high enough to need action that day, we ask you to recheck at home, or come back, before anything is written down.

- We will not start medicine at the first visit as a reflex. If your readings and other risks call for it, the doctor will explain why. If not, the first step is lifestyle change and repeat readings.

- We will not sell you a 60-test health package. A small set of tests answers the question, and we will tell you which and why.

- We will not swap a medicine another doctor prescribed without talking it through with you first.

- We do not have a cardiologist on our panel. Chest pain on exertion, heart failure, pressure that stays high despite three medicines, or very high readings in a young person need a heart or kidney specialist. We will tell you plainly and refer you.

Tests, and when they are worth doing

Once it is confirmed, the doctor will usually check for damage, and for the conditions that travel with it:

- A urine test, for protein or blood, as an early sign of kidney strain.

- A kidney function blood test (creatinine and salts).

- HbA1c, because diabetes and high blood pressure often go together.

- A lipid profile (cholesterol), which together with blood pressure shapes your heart risk.

- An ECG, a tracing of the heart's electrical activity.

- A check of the back of the eye, which may mean a referral to an eye specialist.

If your home and clinic readings disagree, a 24-hour monitor worn at home is the most accurate way to settle it. The doctor will tell you whether you need one.

What it costs

| | Fee |

|---|---|

| General physician consultation | from ₹800 |

| Senior family physician consultation | ₹1,200 |

| HbA1c | ₹399 |

| Lipid profile | ₹399 |

| Urine routine test | ₹110 |

Fees are for booking directly with us. Fees for appointments booked through third-party platforms are set on those platforms and may differ. Blood samples can be collected at home free of charge, with no minimum order. For any other test the doctor suggests, we tell you the price before anything is booked.

Who you will see

A general physician is the right first doctor for a high reading. High blood pressure is managed well in general practice, by a doctor who looks at your weight, sugar, cholesterol and family history together.

Dr. Waquar Yunus (MBBS), our general physician, is in the clinic for the full clinic day, Monday to Saturday, 8:00 AM to 9:00 PM, so you can come before or after work.

Dr. Pratik Banerjee (MBBS, PGCC, Paed (IMA)), family physician with 37 years' experience, consults from 11:00 AM to 1:30 PM and 5:00 to 7:00 PM. Dr. Sushma Vikirna (MBBS, PGDMCH), senior consultant with 40 years' experience, consults Monday to Saturday from 2:00 to 5:30 PM.

Bring your home readings, every previous report, and the strips of any medicines you take.

Frequently asked questions

I feel fine. Do I really need to worry about a high reading?

Feeling fine is normal with high blood pressure, so it tells you little. One high reading is not a diagnosis, but it is a reason to recheck: a week of home readings, or a repeat check at the clinic.

My reading is always higher at the clinic. Which one is right?

Both are real, but the home average usually reflects your everyday pressure better. Bring a week of home readings. If the two still disagree, a 24-hour monitor settles it.

Once I start a blood pressure medicine, is it for life?

For many people it is long-term. Some who lose weight, cut salt and exercise regularly can reduce their dose over time, but that decision is made with your doctor, never by stopping on your own.

Can I just check my blood pressure at the pharmacy?

A pharmacy reading is a useful prompt, not a diagnosis. Machines and technique vary, and a reading taken straight after walking in the cold can be high for that reason alone. Use it as a reason to recheck.

Can I come without an appointment?

Please call first and we will give you a time. If you have a very high reading or symptoms that worry you, say so on the phone and we will find you the earliest slot. With chest pain, breathlessness, weakness, slurred speech or sudden loss of vision, go to a hospital emergency department instead.
