Obesity in Bangladesh: rates, causes and where to get help

How common is obesity in Bangladesh?

Obesity in Bangladesh is still uncommon by world standards: 5.8% of adults have a BMI of 30 or more, according to the latest WHO estimates. Only eight countries have a lower rate.

Yet Bangladesh is one of the most populous countries in the world. A small percentage of a very large population adds up to about 7.2 million adults living with obesity, which is why Bangladesh appears among the 30 countries with the most people affected.

The difference between women and men is striking. The WHO puts the rate at 8.6% for women and 2.7% for men. Among children and teens aged 5 to 19, it is 2.2%, again higher for girls (3.0%) than for boys (1.5%).

What do Bangladesh's own surveys show?

Most national data on weight in Bangladesh come from the Bangladesh Demographic and Health Survey (BDHS), which measures women of reproductive age in every round and, in recent rounds, adults of both sexes. Because it is repeated every few years, it shows trends well.

An analysis of eight BDHS rounds, covering more than 90,000 women aged 15 to 49, found a clear shift in body weight across the whole population. Underweight fell sharply over two decades while overweight and obesity rose steeply.

The researchers describe this as an epidemiological transition from underweight to overweight. Underweight persists, especially among rural women, while overweight grows fastest in towns and cities. Experts call this mix the double burden of malnutrition: too little and too much at the same time.

National surveys often report overweight and obesity together, and some studies use lower Asian cut-offs. That is why you may see much higher figures for Bangladesh than the WHO obesity rate on this page. Both can be correct for their own purpose.

How has obesity in Bangladesh changed since 1990?

In 1990, obesity barely existed in Bangladesh: the WHO estimate is 0.3% of adults. Today it is 5.8%, nearly twenty times higher.

Women drove most of the rise. Their rate went from 0.4% to 8.6%, while men went from 0.2% to 2.7%. The increase has also sped up over time. In the first ten years after 1990 the adult rate rose by only half a percentage point; over the most recent fifteen years or so it rose by more than three and a half points.

Among children and teens, the rate went from 0.3% to 2.2%. For girls it rose from 0.2% to 3.0%. The numbers are still small, but the direction is the same as for adults.

A rise like this is typical of a country going through rapid economic change. As incomes grow and more people move to cities, food and daily activity change faster than bodies and health systems can adapt.

Why is obesity rising in Bangladesh?

Obesity in Bangladesh is rising mainly among women, city dwellers and better-off households. For background on the biology, see our page on the causes of obesity; this section looks at what research in Bangladesh shows.

City life and rising incomes

In the BDHS analysis, overweight was consistently more common among urban women and underweight among rural women. Older age, more education and higher household wealth all raised the odds of overweight and obesity.

A study of five South Asian countries found a similar pattern: overweight and obesity among women rose most in cities and among wealthier women. In Bangladesh, the share of urban women with overweight or obesity went from 13% to 46% over the study period.

Work patterns matter as well. A separate analysis of the latest BDHS found that women who did farm or manual work were less likely to live with obesity, which suggests that the move from physical work to indoor and sedentary jobs plays a role.

Snacks, sweets and sugary drinks

A national survey of almost 10,000 adults aged 20 to 59 asked how often people ate fried snacks, sweet snacks and sugary drinks. Three in four men (77.3%) and about a third of women (35.3%) had sugary drinks every week.

Sweet snacks were even more common: 75.2% of men and 58.7% of women had them weekly. Eating these foods was linked to education and household wealth, and among women, sugary drinks were linked to overweight, sitting for long hours and eating too few fruits and vegetables.

At the same time, national dietary surveys show that typical diets are dominated by cereals, with low intakes of fruit, leafy vegetables, pulses, milk and nuts. Our page on the food environment explains how cheap, energy-dense foods crowd out healthier choices.

Television and time at home

Owning or regularly watching a television was linked to higher odds of overweight among Bangladeshi women across survey rounds. Television may stand for more time sitting and more exposure to food advertising, although surveys like these cannot prove cause and effect.

What does obesity mean for health in Bangladesh?

In Bangladesh, the health effects of extra weight appear at lower BMI levels than in Europe. A WHO expert consultation concluded that many Asian populations have a higher risk of type 2 diabetes and heart disease at a BMI below 25, and suggested extra action points for public health.

Recent national data show the size of the problem. Analysis of the latest BDHS found that 31% of adults had high blood pressure or diabetes, rising to 52% among people aged 50 and over. Many did not know it: 38% of people with diabetes were unaware of their condition.

People living with obesity were three times more likely to be unaware of a blood pressure or blood sugar problem than people who were underweight.

Our page on the health risks of obesity explains how excess weight affects blood pressure, blood sugar and the heart.

What is Bangladesh doing about obesity?

Bangladesh's response focuses on chronic disease services and food rules more than on obesity itself. These are the measures we could verify.

NCD corners in local hospitals

The government has set up NCD corners in subdistrict hospitals, known as upazila health complexes. They screen and treat diabetes, high blood pressure and other chronic diseases close to where people live.

Health workers interviewed in a study of these corners welcomed them and said they had raised awareness. They also reported gaps: no clear guidelines, too few trained staff, limited laboratory tests and shortages of medicines.

A limit on trans fats

The Bangladesh Standards and Testing Institution (BSTI) has capped industrial trans fats at 2% in manufactured foods, including edible oil, decorated cakes, chips and chanachur. Trans fats raise harmful cholesterol and the risk of heart disease and type 2 diabetes.

Where can you get help for obesity in Bangladesh?

In Bangladesh, care for weight-related health problems usually starts at a government health facility or with a private doctor. In the public system, the upazila health complexes in each subdistrict provide basic hospital care, and their NCD corners can check blood pressure and blood sugar.

If you live with obesity, ask for these checks even if you feel well. Because many people do not know they have diabetes or high blood pressure, a simple test can make a big difference. Our doctor visit checklist helps you prepare.

The Diabetic Association of Bangladesh

The Diabetic Association of Bangladesh (DAB) is a non-profit organisation founded by National Professor Mohammad Ibrahim. It runs a large diabetes hospital in Dhaka and set up BIRDEM, which trains specialists in diabetes, endocrine and metabolic disorders. Together they have more than 40 district-level branches.

Many people living with obesity also have, or are at risk of, type 2 diabetes. A DAB or BIRDEM centre can be a good place to ask about weight and diet advice alongside diabetes care. We could not verify a patient organisation dedicated to obesity in Bangladesh.

To understand your own risk, you can also measure your waist; our page on BMI and waist size explains why waist matters, especially for South Asian people.

How does Bangladesh compare with the world and South Asia?

Bangladesh's adult rate of 5.8% is about a third of the world average of 16.2%. For children and teens, 2.2% compares with a world average of 8.2%.

Within South Asia, Bangladesh has the lowest adult obesity rate. India and Nepal are at 8.0%, Sri Lanka at 11.2% and Pakistan much higher at 24.5%.

The pattern of women being more affected than men is shared by all of its neighbours. What stands out in Bangladesh is the speed of change from a very low starting point. See the full ranking on our obesity by country page.

How can Obesity Foundation help people in Bangladesh?

We help people lose weight and feel healthier through good food, suitable exercise and walking. Our help is free and online, so you can use it at home in Dhaka, in a small town or abroad.

Before you start, talk to your doctor first, especially if you have not had your blood sugar or blood pressure checked recently.

• Balance the plate: our free eating plan keeps rice and dal on the menu but helps you eat a smaller portion of rice and more vegetables, fish, eggs and lentils.
• Cut sweet drinks and snacks: try water, plain tea or our ideas for healthy snacks instead of fried and sugary snacks.
• Walk a little more: our walking plan starts very gently and builds step by step.
• Move at home: if going out to exercise is difficult, our low impact cardio routines need only a small space.
• Get support: book a free video meeting (in English), join our club and use our free calculators.

Where to start

You do not need special foods or an expensive gym. A good first step is to look at your rice portion: many people find that a slightly smaller mound of rice, with an extra serving of vegetables or dal, keeps them just as full.

Next, notice when sweet tea, soft drinks and fried snacks creep into the day. Cutting one of these at a time is easier than trying to stop everything at once. Short walks after meals, even inside a compound or on a rooftop, help the body handle blood sugar.

Finally, ask for a blood pressure and blood sugar check once a year. Because so many people in Bangladesh do not know they have diabetes or high blood pressure, knowing your numbers is one of the most useful things you can do.
