Quick answer. Hypertension is a common “silent” condition that usually causes no symptoms, yet it is a leading cause of stroke, heart attack, heart failure and kidney disease – over 1 in 3 Singapore adults are affected, and many do not know it. In Singapore it is generally diagnosed when clinic blood pressure stays at or above 140/90 mmHg on repeated readings (135/85 mmHg at home), and it is managed with lifestyle changes first – cutting salt, exercising, losing excess weight, limiting alcohol and stopping smoking – plus medication when needed. Targets are individualised by your doctor (tighter if you have diabetes or kidney disease). It is covered under the Chronic Disease Management Programme (CDMP), so you can use MediSave for outpatient care alongside CHAS subsidies and Healthier SG support – know your numbers and get screened. Very high blood pressure with symptoms such as chest pain, breathlessness, severe headache or weakness is a medical emergency: call 995.
High blood pressure, or hypertension, is one of the most common chronic conditions in Singapore – affecting more than one in three adults – yet it often causes no symptoms at all, which is why it is called a “silent” condition. Left uncontrolled, it quietly raises the risk of stroke, heart attack, heart failure and kidney damage over time. The good news is that it is easily detected with a simple reading and, in most cases, well controlled through lifestyle changes and, where needed, medication. This guide explains how blood pressure is measured and classified in Singapore, what treatment involves, how it is financed, and when high blood pressure becomes an emergency.
At a glance
| Approach | What it involves | Notes |
|---|---|---|
| Screening | Regular blood pressure checks at a GP, polyclinic or community screening | "Know your numbers" – hypertension usually has no symptoms |
| Diagnosis | Average of repeated clinic readings; home or 24-hour ambulatory monitoring | Clinic threshold ~140/90 mmHg; home ~135/85 mmHg |
| Lifestyle (first-line) | Cut salt (Singaporeans eat ~9g vs ~5g recommended), DASH-style diet, exercise, healthy weight, limit alcohol, stop smoking | Important even alongside medication |
| Medication | ACE inhibitors / ARBs, calcium channel blockers, diuretics – often in combination | Dosing individualised by doctor; do not self-adjust or stop |
| Targets & monitoring | Individualised targets (tighter for diabetes/CKD); regular BP and blood tests | Adherence and follow-up are key to control |
| Financing | MediSave via CDMP ($500/$700/yr, 15% cash co-pay), CHAS subsidies, Healthier SG | Available at polyclinics and participating CHAS GP clinics |
What is hypertension and why it matters
Blood pressure is the force of blood pushing against the walls of your arteries, written as two numbers – systolic (the higher number, when the heart beats) over diastolic (the lower number, when the heart rests) – measured in millimetres of mercury (mmHg).
Hypertension usually produces no warning signs, so people can live with it for years without knowing. Over time, the sustained pressure damages blood vessels and organs, making it a major risk factor for:
- Stroke and heart attack
- Heart failure and an enlarged heart
- Chronic kidney disease and kidney failure
- Eye and blood-vessel damage
Because there are no symptoms to rely on, the only way to know your blood pressure is to measure it. This is why screening – “knowing your numbers” – is so important, particularly if you are older, overweight, have diabetes, or have a family history of high blood pressure or heart disease.
How blood pressure is measured and the categories used in Singapore
A diagnosis is not made from a single reading. Your doctor will take the average of several readings on separate occasions, and may ask you to monitor at home or wear an ambulatory monitor for 24 hours, because home and ambulatory readings tend to run lower than clinic readings.
Singapore’s primary-care guidance generally uses these thresholds:
- Clinic blood pressure: hypertension is diagnosed at 140/90 mmHg or higher.
- Home / ambulatory blood pressure: the equivalent threshold is lower, at 135/85 mmHg or higher.
Local categories broadly are: normal (below 130/85), high-normal (130-139 / 85-89), and then Grade 1 (140-159 / 90-99), Grade 2 (160-179 / 100-109) and Grade 3 (180/110 or higher). The exact figures and how they apply to you should always be interpreted by a doctor, who will also consider your overall cardiovascular risk.
Treatment targets and lifestyle as first-line care
Targets are individualised. Your doctor sets a goal based on your age, overall health and cardiovascular risk. People with diabetes or chronic kidney disease are often given tighter targets, while blood pressure is generally not lowered below about 120/70 mmHg because the added benefit beyond that is uncertain.
For most people, lifestyle changes come first and remain important even if medication is later added:
- Cut down on salt. Singaporeans typically eat around 9g of salt a day – almost double the recommended limit of about 5g (roughly one teaspoon). Reducing salt can lower blood pressure meaningfully.
- Eat a heart-healthy, DASH-style diet rich in fruit, vegetables, wholegrains and low-fat dairy, and lower in saturated fat.
- Be active – aim for regular moderate exercise most days.
- Reach and keep a healthy weight.
- Limit alcohol and stop smoking.
Medications when lifestyle is not enough
When lifestyle changes alone do not bring blood pressure to target, or when readings are high to begin with, doctors prescribe medication. Common first-line classes used in Singapore include:
- ACE inhibitors and ARBs (angiotensin-receptor blockers)
- Calcium channel blockers
- Diuretics (“water pills”)
Many people need more than one medication, sometimes combined in a single pill. Each class works differently, and the choice depends on your age, other conditions and how you respond – so dosing must be decided by your doctor and never self-adjusted. Two things matter most for success: taking medication consistently as prescribed (adherence) and regular monitoring, including blood pressure checks and occasional blood and kidney tests. Do not stop your medication on your own, even if you feel well, because hypertension has no symptoms to guide you.
Cost, MediSave and subsidies
Hypertension is one of the chronic conditions covered under the Chronic Disease Management Programme (CDMP), which is designed to reduce out-of-pocket costs for ongoing outpatient care.
- MediSave: You can use MediSave for outpatient treatment of hypertension under CDMP – up to $500 per patient per year for most patients, and up to $700 for those with complex chronic conditions. A 15% cash co-payment applies to each claim.
- CHAS: CHAS cardholders can receive government subsidies of up to $500 per year for chronic conditions at participating GP clinics; Pioneer and Merdeka Generation cardholders can receive special subsidies.
- Healthier SG: Enrolling with a regular family doctor under Healthier SG supports continuity of care and access to subsidised chronic-disease management.
You can manage hypertension affordably at polyclinics (with subsidised rates) or at participating CHAS GP clinics. Actual fees vary by clinic and your eligibility, so check current charges and subsidies with your provider.
When to see a doctor – and when it is an emergency
Because hypertension is silent, get your blood pressure checked even if you feel well – at a polyclinic, GP, or community screening. See a doctor if your readings are repeatedly high, or if you have diabetes, kidney disease or a family history of heart disease.
A hypertensive emergency requires urgent care. Very high blood pressure together with symptoms such as:
- Chest pain or tightness
- Breathlessness
- Severe headache
- Sudden weakness, numbness, slurred speech, vision changes or confusion (signs of a possible stroke)
…needs immediate attention. Go to the nearest A&E or call 995 straight away. Do not wait to see if it settles on its own.
