Singapore – Health Issues

What are the most common health issues and diseases in Singapore?

The majority of Singapore’s disease burden stems from non-communicable, lifestyle-driven conditions. Hypertension, elevated blood cholesterol, joint problems and arthritis, and diabetes are among the most frequently diagnosed chronic illnesses in the population. These conditions tend to cluster together: high blood pressure, hyperlipidaemia, and diabetes share overlapping risk factors, so it is not unusual for a single patient to be managing all three simultaneously.

Cancer was responsible for 26.4% of all deaths in Singapore as of 2021, making it the nation’s leading killer. The most lethal cancer types vary by sex: among men, colorectal cancer (17.2%), lung cancer (14.8%), and prostate cancer (13.0%) are the top three, while women are most frequently diagnosed with breast cancer (29.1%), followed by colorectal (13.4%) and lung (7.5%) cancers.

Cardiovascular disease accounted for nearly one in three deaths in Singapore in 2021, ranking it just behind cancer as a cause of mortality. Though hyperlipidaemia rates have shown some decline over time, roughly one in three Singapore residents still lives with hyperlipidaemia and hypertension — underscoring the ongoing burden these conditions place on the healthcare system.

Certain conditions stand out for their unusually high prevalence in Singapore relative to other nations. Myopia, colorectal cancer, nasopharyngeal cancer, type 2 diabetes, and thalassaemia are among those found at notably elevated rates. Singapore has one of the highest concentrations of myopia globally — at least 30% of children entering Primary One have impaired vision, a figure that climbs to around 60% by the upper primary years. Thalassaemia, an inherited blood disorder that frequently leads to anaemia, is the single most common genetic condition in the country.

Disease risk also varies by ethnicity within Singapore. Smoking rates are disproportionately higher among the Malay community, while diabetes is more prevalent among both Malay and Indian populations. Expats of South Asian, Malay, or Chinese descent should note that certain genetic predispositions and lifestyle-related risks may be amplified within the local context.

Is Singapore considered a healthy country? How do health outcomes compare internationally?

On virtually every standard global health measure, Singapore performs at or near the top of the rankings. According to the Department of Statistics, average life expectancy at birth reached 83.5 years in 2024 — 85.6 years for women and 81.2 years for men. To put this in perspective, the global average stands at roughly 73 years, meaning Singaporeans live more than a decade longer than the worldwide norm.

Globally, Singapore holds the seventh-highest life expectancy as of 2023, with male and female averages of 82.13 and 86.42 years respectively, yielding a combined average of 84.27 years. The country has also earned recognition for its healthy life expectancy — longevity researcher Dan Buettner has described Singapore as having “the highest health-adjusted life expectancy in the world.”

That said, a long life does not automatically translate to a healthy one throughout its entirety. The flip side of increased longevity is that Singaporeans are living longer with illness, particularly in their final years. The country faces mounting public health challenges driven by its rapidly ageing population, and a society-wide commitment to healthy ageing and positive lifestyle habits is increasingly recognised as essential.

For the most current statistics, readers should consult the Singapore Department of Statistics and the WHO Singapore country data page, as these figures are subject to periodic revision.

What infectious diseases or environmental health risks should expats be aware of in Singapore?

Singapore’s warm, humid tropical climate sustains vector-borne disease transmission throughout the year, with dengue fever representing the most significant infectious disease threat. Mosquitoes capable of spreading dengue are present year-round, and suppressing their populations remains a central pillar of Singapore’s public health strategy. Dengue can affect anyone — from long-term residents to those who arrived last week — and case numbers tend to spike during seasonal peaks. Classic symptoms include abrupt high fever, intense headache, pain behind the eyes, and muscle and joint aches accompanied by a rash.

To address dengue at its source, Singapore’s National Environment Agency (NEA) has pioneered an innovative biocontrol approach. Male Wolbachia-carrying Aedes mosquitoes are released into the environment, where they mate with wild females to produce eggs that fail to develop, thereby reducing the overall mosquito population. Project Wolbachia was extended to five new sites from October 2024, bringing its total reach to 580,000 households. Despite this progress, expats should continue using insect repellent and regularly inspect their surroundings for standing water — flower pot saucers, clogged gutters, and ornamental water features are all common breeding grounds.

Enterovirus infection is another endemic condition in Singapore, occasionally flaring into larger outbreaks. Hand, foot and mouth disease (HFMD), which is caused by enteroviruses, disproportionately affects young children, so families with small kids should remain particularly alert during periods of elevated transmission.

Singapore’s food and water safety standards are among the highest in Asia. Tap water is safe to drink straight from the tap and is subject to rigorous quality monitoring. The city’s vibrant hawker centre culture means most people eat street food regularly — and while hygiene standards are generally high, basic precautions around raw shellfish and salads from unfamiliar vendors remain sensible. Hepatitis A vaccination is commonly recommended for newcomers, as the virus spreads via contaminated food and water.

Standard vaccination guidance for Singapore includes being up to date on routine immunisations — MMR, diphtheria, tetanus, and polio — along with hepatitis A and typhoid vaccines. Rabies vaccination is worth considering for those likely to have contact with animals. Expats should consult their home country’s dedicated travel health service — such as NHS Fit for Travel, the CDC Traveler’s Health portal, or an equivalent national body — as well as Singapore’s Ministry of Health (MOH), since recommendations can evolve.

Singapore’s ambient air quality is typically good, but the city-state is periodically enveloped by transboundary haze originating from agricultural burning in neighbouring countries, most commonly between June and October. During serious haze episodes, the Pollutant Standards Index (PSI) can climb into unhealthy territory. Those with asthma, other respiratory conditions, or young children should track the NEA’s live air quality readings and reduce time outdoors when levels are elevated.

Is smoking common in Singapore, and what are the laws around it?

Smoking rates in Singapore are comparatively modest by regional standards and have been declining steadily. The proportion of daily smokers fell from 9.2% in 2022 to 8.8% in 2023, the lowest figure on record. As of 2022, 16.5% of the total population used tobacco in some form, with a pronounced gender disparity — 27.9% of men versus just 4.0% of women.

Singapore operates one of the most stringent tobacco control frameworks anywhere in the world. The minimum legal age for purchasing or consuming tobacco was raised from 18 to 21 years in 2021. Plain packaging for cigarettes was introduced in 2020, and a blanket prohibition on both heated tobacco products and e-cigarettes is firmly in place. This last measure is especially important for expats to understand: importing, possessing, using, or selling e-cigarettes — even for entirely personal use — is unlawful in Singapore, and meaningful penalties apply. This stands in stark contrast to the legal but regulated status of vaping across most of Europe, Australia, and North America.

Designated smoking areas (DSAs) exist, but the list of locations where smoking is forbidden is lengthy and strictly enforced. Smoking is prohibited in virtually all indoor public spaces, workplaces, public transport, shopping centres, food establishments, educational facilities, and within prescribed distances of building entrances and bus stops. The health hazards of second-hand smoke are well documented — it contains at least 60 known carcinogens — and non-smokers exposed to it face elevated risks of lung cancer, respiratory illness, and heart disease.

Public opinion in Singapore is strongly opposed to smoking, and enforcement officers actively issue on-the-spot fines. Expats who smoke should review the current list of prohibited zones maintained by the NEA before they arrive, and should carry no illusions about leniency.

Is obesity or poor diet a significant health concern in Singapore?

Although Singapore remains far less affected by obesity than many high-income countries, rising rates represent a meaningful and growing public health challenge. The share of residents classified as obese (BMI ≥30.0 kg/m²) climbed from 10.5% in 2019–2020 to 12.7% in 2023–2024. This is well below obesity levels seen in the United States (roughly 40%) or the United Kingdom (approximately 28%), yet the upward trend is concerning given obesity’s close relationship with diabetes and heart disease.

Insufficient physical activity and poor dietary habits are the principal modifiable contributors to both obesity and chronic illness, and the Ministry of Health (MOH) alongside the Health Promotion Board (HPB) have made improving these behaviours a national priority. Singapore’s food landscape revolves around hawker centres — lively communal dining spaces where a vast array of dishes are served at low prices. While hawker food is deeply embedded in local culture and genuinely enjoyable, many classic preparations carry high loads of sodium, saturated fats, and refined carbohydrates.

Several government-led initiatives have targeted dietary quality directly. Sugar-sweetened beverages represent the largest single source of added sugar in the Singaporean diet, and to counter this, Nutri-Grade labelling requirements and advertising restrictions for prepacked and freshly prepared drinks were introduced in December 2022 and 2023 respectively. These measures have had a measurable effect: the median sugar content of prepacked Nutri-Grade beverages dropped from 7.1% in 2017 to 4.6% as of September 2023.

Through the Healthier SG national programme, Singapore Citizens aged 40 and above can enrol with a family doctor to access personalised chronic disease management and weight support. Participants requiring help with obesity receive evidence-based lifestyle guidance tailored to their specific health goals. Permanent residents who are expats may be eligible for certain Healthier SG benefits — eligibility details should be verified directly with the MOH.

Encouragingly, the proportion of residents meeting physical activity guidelines rose significantly from 78.5% to 84.7% in 2024, recovering to pre-pandemic levels. Singapore’s well-maintained parks, cycling infrastructure, and outdoor fitness stations make staying active straightforward, and while the climate is hot and humid, year-round outdoor exercise is entirely feasible for those willing to adapt their routine.

What are the mental health attitudes and services like in Singapore?

In 2024, 15.4% of Singapore residents reported poor mental health — a figure that has remained broadly stable, though it peaks sharply among the 18–29 age group, where 25.5% reported difficulties. Mental health is discussed more openly in Singapore than in previous decades, but the stigma prevalent across many East Asian cultures persists, and it can still discourage people — particularly in professional or family settings — from reaching out for support.

Despite the concentration of challenges among younger adults, there are signs that Singaporeans across all demographics are becoming more willing to seek help for psychological concerns. Government-led awareness campaigns, a more health-literate younger generation, and the lasting impact of the COVID-19 pandemic on perceptions of wellbeing have collectively contributed to this shift.

Under the National Mental Health and Well-being Strategy, the government has been systematically expanding mental health provision across all levels of the community. “First Stops for Mental Health” services have been introduced to ensure no one is turned away from the wrong door — these hubs are designed to meet people where they are and connect them efficiently to appropriate care. A national mental health line (1771), known as Mindline SG, launched in June 2025 to provide around-the-clock support via phone, text, and online chat.

Public mental health care is delivered through the Institute of Mental Health (IMH) — Singapore’s dedicated psychiatric hospital — alongside community mental health teams and the polyclinic network. This system is broadly comparable to publicly funded psychiatric services in countries with universal healthcare, though waiting times for non-urgent specialist appointments can stretch considerably. Private psychiatrists and psychologists offer far shorter waiting times but at substantially higher cost — typically SGD 150–350 or more per session. Comprehensive health insurance that includes mental health coverage is strongly advisable.

For expats specifically, the pressures of relocation, adjustment to a demanding work culture, and the absence of established social networks can all intensify stress and anxiety. The growing number of people living alone in Singapore adds another layer of risk around social isolation. Expat community groups, organised social networks, and employer-provided employee assistance programmes (EAPs) can offer valuable informal outlets alongside professional support.

Are there any health risks specific to expats living in Singapore?

For those arriving from cooler, temperate climates, adapting to Singapore’s persistently hot and humid weather — with daytime temperatures typically ranging from 25°C to 34°C — is one of the most immediate physical challenges. Heat exhaustion and dehydration are genuine hazards in the first weeks, especially for those engaging in outdoor exercise or walking extensively. Staying well hydrated, avoiding strenuous outdoor activity during the hottest midday hours, and wearing lightweight, breathable clothing are simple but important measures.

Dengue fever warrants particular attention from new arrivals, as individuals from non-tropical countries will have had no prior exposure to the virus and therefore no immunity. The risk is present throughout the year. Using insect repellent containing DEET or picaridin, wearing long sleeves during evening outdoor activities, and confirming that window screens and air conditioning are in good working order at home are all effective precautions. Learn the hallmark symptoms — abrupt high fever, severe headache, pain behind the eyes, and aching muscles and joints with a distinctive rash — and seek medical attention promptly if they arise.

Dietary adjustment is another consideration. Singapore’s cuisine is richly varied and generally nutritious, but the high sodium levels characteristic of many hawker staples can, over time, contribute to elevated blood pressure. Expats managing pre-existing conditions such as hypertension or diabetes should be proactive about monitoring their food intake as they settle into local eating habits.

Registering with a GP or polyclinic soon after arrival is strongly recommended. Singapore’s polyclinic network provides subsidised primary care for citizens and permanent residents; expats on employment passes can access these services at unsubsidised rates or opt for private general practice. Securing comprehensive health insurance — covering inpatient care, outpatient consultations, specialist treatment, and mental health — is essential, given that private healthcare in Singapore carries significant costs.

Health screenings are strongly encouraged by Singapore’s health authorities and represent a sensible step for any new resident. Screening uptake has recovered to pre-COVID levels as of 2024. Tests for diabetes, hypertension, cholesterol, and common cancers — including colorectal, breast, and cervical — are widely accessible, with several available free of charge or at reduced rates under national programmes for eligible residents.

Where can expats find reliable health information and services in Singapore?

Singapore maintains a robust infrastructure for public health communication. The following official sources serve as the most authoritative starting points for expats seeking information:

• Ministry of Health (MOH): moh.gov.sg — the definitive source for health policy, disease updates, vaccination guidance, and healthcare subsidies. The MOH publishes the National Population Health Survey and regular disease surveillance reports.
• Health Promotion Board (HPB): hpb.gov.sg — the lead agency for preventive health, lifestyle promotion, and wellness initiatives. The HPB administers HealthHub, a digital platform for personal health tracking, appointment management, and educational resources.
• National Environment Agency (NEA): nea.gov.sg — provides live air quality data (PSI and PM2.5 readings), dengue cluster maps, and broader environmental health updates.
• HealthXchange: healthxchange.sg — a patient-oriented health information portal operated by SingHealth, offering clear and medically reviewed content on a wide range of conditions.
• WHO Singapore country profile: data.who.int/countries/702 — for internationally comparable health data and population indicators.

The Health Promotion Board runs the I Quit national smoking cessation programme, which includes QuitLine — a tele-counselling service for those seeking to stop smoking or vaping. For mental health support, Mindline SG (1771) operates around the clock, and the MOH website hosts a directory of available mental health services across the country.

Before relocating to Singapore, consulting your home country’s official travel health authority is advisable — whether that is NHS Fit for Travel in the UK, the US Centers for Disease Control and Prevention (CDC), or your national equivalent — for vaccination recommendations and any active disease advisories. Guidance can change, so verify current advice close to your departure date and revisit it once you have settled in.

Health regulations, vaccination requirements, subsidy eligibility criteria, and disease alerts are all subject to change. Always confirm specific figures, fees, or requirements with official Singapore government sources before making any healthcare decisions.

Frequently Asked Questions About Health Issues in Singapore

Is Singapore a safe and healthy place to live?

Singapore residents’ life expectancy at birth reached 83.5 years in 2024, placing the country among the world’s leading performers. The healthcare infrastructure is excellent, tap water is safe, food standards are high, and public health laws are robustly enforced. While chronic diseases and tropical illnesses such as dengue are real concerns, Singapore offers an exceptionally safe and healthy living environment for the vast majority of expats.

Do I need vaccinations before moving to Singapore?

No vaccinations are mandated for entry to Singapore for most nationalities, but several are strongly advisable. These typically include hepatitis A, typhoid, and up-to-date routine immunisations such as MMR, tetanus, diphtheria, and polio. Consult your home country’s travel health authority and Singapore’s Ministry of Health for the most current recommendations prior to relocation.

Is dengue fever a serious risk for expats in Singapore?

Yes — dengue is endemic throughout Singapore and presents a genuine risk year-round, particularly for newcomers who have never been exposed to the virus and have no pre-existing immunity. Suppressing mosquito populations is a cornerstone of Singapore’s public health response. Expats should apply insect repellent consistently, eliminate standing water around their homes, and seek prompt medical attention if they develop a sudden high fever along with flu-like symptoms.

Are e-cigarettes and vaping legal in Singapore?

No. Singapore enforces a total ban on e-cigarettes and heated tobacco products. Importing, possessing, purchasing, using, or selling these items is illegal, regardless of where they were originally bought. The prohibition applies equally to residents and visitors. Fines can be imposed for violations, and expats who vape should be fully aware of this law before arriving.

How good is mental health support in Singapore for expats?

Public mental health services are delivered through the Institute of Mental Health and community health teams, and the government has been broadening access in recent years. “First Stops for Mental Health” hubs offer a clear, welcoming entry point to support for anyone in distress. Private psychiatrists and psychologists are plentiful but expensive, making comprehensive health insurance that covers mental health treatment essential for expats.

Is the tap water safe to drink in Singapore?

Yes, entirely. Singapore’s tap water meets WHO drinking water guidelines and can be consumed directly without treatment. A significant proportion of the country’s water supply is produced domestically through desalination and water reclamation processes, with imports supplementing supply. Bottled water is available everywhere, but tap water is completely safe for everyday consumption.

How bad is air pollution in Singapore?

Air quality in Singapore is generally good. However, seasonal transboundary haze — caused by land-clearing fires in neighbouring countries — can periodically affect the city between June and October. When haze is severe, time spent outdoors should be limited, especially for children, older adults, and those with respiratory conditions. Up-to-date PSI and PM2.5 data can be tracked in real time via the NEA website at nea.gov.sg.

What are the biggest diet-related health concerns for expats in Singapore?

Singapore’s hawker food scene is diverse and hugely enjoyable, but many traditional preparations are high in sodium, saturated fat, and refined carbohydrates. Sugar-sweetened drinks represent the largest single contributor of added sugar to the local diet, and excessive sugar consumption is closely linked to both obesity and diabetes. Expats should seek variety in their food choices, take advantage of the HPB’s Healthier Choice Symbol and Nutri-Grade labelling to identify lower-sugar and lower-fat options, and prioritise adequate hydration in Singapore’s tropical heat.
