According to the World Health Organisation, 1.9 billion adults globally were overweight in 2016, and of these, 650 million were obese.
World Health Organisation defines overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health.
Obesity is a major risk factor for several chronic diseases including diabetes, cardiovascular diseases, and cancer. This can seriously affect a person’s health, and for certain individuals, it could be fatal.
The issue of being overweight and obesity is alarming in Malaysia. According to the National Health and Morbidity Survey (NHMS) 2019 , 50.1% of Malaysian adults are overweight and obese. Out of the 50.1% of Malaysian adults, 30.4% were overweight and 19.7% obese.
Obesity is more than just outward appearance; it is a medical issue that needs to be addressed because of its link to non-communicable diseases in Malaysia such as cardiovascular diseases (heart attacks, stroke, hypertension, hypercholesterolemia), diabetes, cancers, and chronic respiratory diseases.
The following are some risk factors that increase an individual’s risk of obesity:
The most commonly used measurement for obesity is the Body Mass Index (BMI), which is a simple measurement metrics to classify overweight and obesity in adults.
BMI is calculated by dividing an individual’s weight (in kilograms) by his or her height (in metres) squared.
BMI = body weight (kg) / height x height (m2)
An individual is considered overweight when their BMI ranges between 23 - 27.4 kg/m 2 and obese when their BMI is above 27.5 kg/m 2 .
Classification | BMI |
---|---|
Underweight | Less than 18.5 |
Normal weight | 18.5 – 22.9 |
Overweight | More than 23 |
Pre-obese | 23 – 27.4 |
Obese-I | 27.5 – 34.9 |
Obese-II | 35 – 39.9 |
Obese-III | More than 40 |
The waist circumference can also be measured to determine abdominal obesity in an individual.
Abdominal obesity occurs when the measurement of waist circumference is:
Obesity is linked to numerous health complications. Some of these complications are chronic and can be life threatening if medical intervention is not provided:

Bariatric surgery is an operation that helps an individual to lose weight by making changes to the digestive system. This procedure is performed by either making the stomach smaller or by bypassing a part of the small intestine.
Bariatric surgery is an option for people with BMI above 32 kg/m 2 with medical conditions. To be eligible for surgery you will need to consult a multidisciplinary bariatric team.
Laparoscopic Sleeve Gastrectomy is a surgical weight-loss procedure in which about 70% of the stomach is removed, leaving a tube-shaped stomach about the size and shape of a banana. Limiting the size of your stomach restricts the amount of food you can consume. It also prompts hormonal changes that assist with weight loss.
Laparoscopic Gastric Bypass involves creating a small stomach pouch and bypassing a part of the small intestines. The rest of the stomach remains functional and remains connected to the intestine. This surgery results in hormonal changes, which leads to better control of blood sugars in diabetic patients and results in other metabolic improvements.
A non-surgical procedure to treat obesity is to insert an intragastric balloon. An intragastric balloon is an inflatable medical weight loss device that is temporarily placed into the stomach of patients who are overweight or obese.
This device can be endoscopically inserted into the stomach or as a swallowable device without endoscopy.
This device aids in weight loss if surgery is not an option. The balloon limits the amount of food the stomach can hold and thereby creates an early feeling of fullness and satiety.
Healthy food choices and activities are two main ways to overcome obesity. Individuals can avoid weight gain and therefore, obesity by:
