Overview
Obesity is excess body fat that raises the risk of diabetes, hypertension, heart disease, arthritis and several cancers — and it is rising globally alongside ultra-processed foods, sugary drinks and sedentary work. It is a medical condition shaped by environment and biology, not a moral failing. Even a 5-10% weight loss measurably improves health.
Symptoms
Body mass index of 30 or above (25-30 is overweight)
Increasing waist size
Breathlessness with mild activity
Joint pains, especially knees
Snoring or poor sleep
Tiredness and low energy
Causes & risk factors
Energy-dense diets — fried foods, sugary drinks, large portions
Sedentary work and little daily movement
Genetics and family eating patterns
Stress, poor sleep and emotional eating
Certain medicines and hormonal conditions
Treatment & self-care
Sustainable change beats crash dieting: a dietitian can build a realistic plan around your local foods — more vegetables, beans and whole grains, fewer fried foods and sugary drinks — paired with activity you can keep up, like brisk daily walking. Doctors screen for and treat related conditions, and medical or surgical options exist for severe obesity. Slimming teas and unregulated pills are unsafe and do not produce lasting loss.
See a doctor urgently if
BMI over 30, or over 25 with hypertension or diabetes in the family
Breathlessness, chest discomfort or marked snoring with daytime sleepiness
Weight gain despite genuine diet and activity changes
Considering weight-loss medication or surgery
