Also known as: Obesity (BMI ≥ 30)
Obesity is a complex, chronic medical condition characterised by excessive body fat accumulation that presents a risk to health. It results from a combination of genetic, environmental, and behavioural factors.
Obesity is a global health challenge affecting over 1 billion people worldwide. It is now recognised as a chronic, relapsing disease — not simply a matter of willpower. The condition involves complex interactions between genetics, hormones, environment, and behaviour.
Excess body fat, particularly visceral (abdominal) fat, increases inflammation and disrupts normal metabolic function. This leads to an elevated risk of numerous conditions including type 2 diabetes, cardiovascular disease, certain cancers, and musculoskeletal disorders.
Modern treatment takes a comprehensive approach combining dietary changes, physical activity, behavioural therapy, and when appropriate, medications or bariatric surgery. Sustainable, gradual weight loss of 5–10% can yield significant health improvements.
People with Obesity often experience the following symptoms.
Body mass index of 30 or above is the standard diagnostic threshold, though BMI does not distinguish between fat and muscle mass.
Difficulty with physical activity, breathlessness during mild exertion, and reduced stamina due to excess body weight.
Increased mechanical stress on joints, particularly the knees, hips, and lower back, leading to chronic pain and accelerated wear.
Obstructive sleep apnoea, snoring, and poor sleep quality are common, contributing to daytime fatigue and further weight gain.
Certain factors may increase your likelihood of developing Obesity.
Common approaches to managing obesity. Always consult a healthcare provider for personalized treatment.
A reduced-calorie, nutrient-dense diet tailored to individual preferences. No single diet is best — adherence matters most.
At least 150–300 minutes of moderate-intensity exercise per week, combined with resistance training to preserve muscle mass during weight loss.
GLP-1 receptor agonists (semaglutide, tirzepatide) and other medications can significantly aid weight loss when combined with lifestyle changes.
Surgical options like gastric bypass or sleeve gastrectomy may be considered for BMI ≥ 40 or BMI ≥ 35 with obesity-related complications.
Diagnosis involves BMI calculation, waist circumference measurement, and assessment of obesity-related comorbidities. Blood tests may include fasting glucose, lipid panel, liver function, and thyroid function to evaluate metabolic impact and rule out secondary causes.
Consult a doctor if your BMI is 30 or above, if you are experiencing weight-related health problems, or if you have difficulty losing weight despite lifestyle changes.
Steps that may help reduce the risk of developing or worsening obesity.
Regular physical activity from childhood through adulthood
Balanced diet with appropriate caloric intake
Limit ultra-processed foods and sugary beverages
Adequate sleep (7–9 hours for adults)
If left untreated or poorly managed, obesity may lead to:
No. Obesity is a complex disease involving genetic, hormonal, environmental, and psychological factors. Many people with obesity have metabolic adaptations that make weight loss and maintenance significantly harder.
While some individuals with higher BMI may have normal metabolic markers initially, carrying excess weight over time increases health risks. Regular monitoring is important regardless of current health status.
GLP-1 receptor agonists have shown strong safety and efficacy data in large clinical trials. Common side effects are gastrointestinal. Discuss risks and benefits with your doctor.
