High Blood Pressure After 60: A Home Care Guide

What the numbers mean

Blood pressure is written as two numbers, such as 140/90 mmHg. The top (systolic) is the pressure when the heart beats; the bottom (diastolic) when it rests. In older adults, the top number often rises with stiffer arteries, while the bottom may fall. Doctors diagnose hypertension from repeated readings, in the clinic or at home, above about 140/90 in clinic (or about 135/85 at home), though thresholds and targets differ by guideline, age and other conditions. Your doctor will say what range is right for your parent. Very high readings, for example above 180/120, with symptoms, are an emergency.

Why it matters

Sustained high pressure damages blood vessels and organs: the brain (stroke, vascular dementia), heart (heart attack, heart failure, rhythm problems), kidneys, eyes and arteries. Lowering pressure reduces these risks, even in people over 80, when done carefully. See preventing a second stroke, heart failure at home and chronic kidney disease home care.

Measuring accurately at home

Home readings are valuable for diagnosis and treatment. They avoid "white-coat" effect (higher in the clinic) and detect "masked" hypertension (normal in clinic, high at home); see white-coat and masked hypertension.

• Choose a validated upper-arm monitor with the right cuff size; wrist monitors are less reliable and need careful positioning; see bp monitor buying guide, cuff size and bp accuracy, wrist bp monitor pros and cons and voice bp monitor for low vision.
• Technique: sit quietly for five minutes, back supported, feet flat, legs uncrossed, arm resting at heart level on a table, cuff on bare skin; no talking, no tea, coffee, smoking or exercise for 30 minutes before; empty bladder. Take two readings one minute apart and record both. See how to measure blood pressure at home.
• When: as the doctor advises; commonly morning (before medicines and breakfast) and evening, for a week before a visit, or daily for a while.
• Standing readings: if your parent has dizziness, ask the doctor about measuring after lying and standing; see dizziness and low blood pressure when standing.
• Keep a log with date, time, readings, pulse and any symptoms; take it to every visit; see bp log and what to tell the doctor.
• Check the monitor against the clinic device occasionally; see calibrating and replacing health devices.
• Do not chase single high readings: they vary with stress, pain and activity. Recheck after rest.
• Do not take extra tablets because a reading is high. Call the doctor.

Targets and the older adult

Targets are individual. In fit older adults, doctors often aim for lower pressure; in frail people or those prone to falls and dizziness, targets are more relaxed. Ask: What range should we aim for at home? What readings are too high or too low to wait on? When should we call? See normal ranges for older adults. Pressure that is too low causes dizziness, falls, fainting and confusion; report it just as you would high readings.

Food: reducing salt and eating well

Salt is the main dietary driver of blood pressure in many people.

• Cut down gradually: reduce added salt in cooking, avoid adding salt at the table, limit pickles, papad, chutneys, namkeen, chips, instant noodles, processed and packaged foods, salted nuts, cheese and restaurant food. Read labels for sodium.
• Add flavour with lemon, herbs, spices, garlic, ginger, curry leaves and tamarind.
• Do not use "low sodium" salt substitutes without asking the doctor; many contain potassium, which is unsafe with kidney disease or some medicines.
• Eat more vegetables, fruit, pulses, whole grains and curd (potassium and fibre help); check with the doctor if kidney disease is present; see nutrition for kidney disease.
• Choose healthier fats: less ghee, vanaspati and deep-fried foods; see nutrition for heart health after 60.
• Keep to a healthy weight, without crash diets; see weighing scale and weight loss in seniors.
• Limit alcohol.
• Limit very strong tea and coffee if they raise pressure; do not drink them before measuring.
• Stay hydrated unless fluids are restricted; see hydration for older adults.
• Beware of herbal products and "natural BP remedies": some raise pressure or interact with medicines; see supplements and medicine interactions.
• Festivals and weddings: plan, as rich, salty food is common.

Activity, sleep and stress

Regular gentle exercise lowers blood pressure; walk most days, build slowly; see walking programme for older adults and exercise with heart disease. Avoid straining and heavy lifting. Sleep well; snoring and sleep apnoea raise pressure; see sleep apnoea in older adults. Manage stress with breathing, prayer, hobbies and company; see breathing techniques for relieving stress and anxiety. Stop tobacco in all forms.

Medicines: safe habits

Most older adults with hypertension need medicines, often more than one. This guide names none. What matters at home:

• Take them every day, at the same time, as prescribed, even if you feel well. Stopping can allow pressure to rebound.
• Never stop, skip, halve or change doses without the doctor, including when readings are normal or low; call for advice.
• Use a pill organiser and alarms; see pill organiser guide and medicine reminders for forgetful parents.
• Watch for side effects: dizziness, fainting, swelling of ankles, dry cough, excessive urination, cramps, weakness, rash, palpitations; report them; do not stop the tablets yourself; see medicine side effects families should watch.
• Do not combine with painkillers, herbal products, cold remedies or supplements without asking, since some raise blood pressure or harm the kidneys; see painkillers and older adults.
• Keep a current list and show every doctor and pharmacist.
• Plan refills in advance and for travel.
• Tell the doctor about cost or worries that affect adherence.
• Review regularly: doses may need to change with weight loss, illness or kidney changes; see polypharmacy and deprescribing.

Dizziness, falls and low pressure

In older adults, treatment can lower pressure too far, especially on standing, after meals, in hot weather or with dehydration. Signs: dizziness, light-headedness, blurred vision, fainting, falls. Rise slowly; sit at the edge of the bed for a minute; keep hydrated; avoid hot baths; report episodes. See dizziness and low blood pressure when standing and falls risk assessment at home.

Warning signs and emergencies

Call 112 if high blood pressure comes with: chest pain or pressure; severe breathlessness; sudden weakness, face drooping or slurred speech (see stroke warning signs and the first hour); sudden severe headache; sudden vision loss; confusion; fits; fainting; or vomiting with severe headache. Do not drive yourself.

Call the doctor the same day if readings are very high (the level the doctor gave you, or above about 180/110 on repeat) without symptoms, readings are very low with dizziness, there is new swelling, breathlessness on lying, palpitations or marked side effects. Do not give extra tablets on your own.

Related conditions

Hypertension often coexists with diabetes, kidney disease, heart disease and atrial fibrillation; see diabetes at home after 60, atrial fibrillation and blood thinners and monitoring kidney disease at home.

Family support

Learn to measure correctly; keep the log; cook with less salt for everyone; walk together; keep medicines on schedule; keep appointments; and be calm in emergencies. See home health monitoring starter kit and how often to check vitals.

When to ask a professional

A doctor diagnoses hypertension, sets targets and adjusts medicines. A cardiologist or nephrologist helps in complex cases. A dietician helps with low-salt meals. A pharmacist can answer questions. For senior services, call Elderline 14567. In an emergency, call 112.
