Obesity is a complex health condition characterized by excessive body fat accumulation that poses risks to overall health. It is typically measured using the Body Mass Index (BMI), where a BMI of 30 or higher is classified as obese. Obesity is a growing global health concern, affecting millions of people across different age groups and socioeconomic backgrounds.

- Genetics: Family history can influence metabolism and fat storage.
- Medical Conditions: Hypothyroidism, polycystic ovary syndrome (PCOS), and hormonal imbalances can contribute to weight gain.
- Psychological Factors: Stress, emotional eating, and sleep disorders play a role.
Health Risks of Obesity
Obesity is associated with serious health complications, including:
- Cardiovascular Diseases: Increased risk of heart disease, high blood pressure, and stroke.
- Type 2 Diabetes: Excess fat affects insulin sensitivity, leading to diabetes.
- Joint Problems: Osteoarthritis due to excess weight on joints.
- Respiratory Issues: Sleep apnea and breathing difficulties.

Prevention and Management
Obesity can be managed through lifestyle changes such as:
