Obesity
Obesity is a growing global health concern affecting millions of people. It occurs when the body accumulates excessive fat, leading to serious health problems such as diabetes, heart disease, and hormonal imbalances. Understanding its causes, symptoms, complications, and management options is essential for maintaining long-term health.
Obesity is a medical condition where a person has a Body Mass Index (BMI) of 30 or above. It results from an imbalance between calorie intake and calorie expenditure, causing the body to store excess fat.
Common Causes of Obesity
- Poor Diet Choices
High consumption of calories, sugary foods, processed snacks, and fast food leads to weight gain.
- Sedentary Lifestyle
Lack of physical activity reduces the number of calories burned, contributing to fat buildup.
- Genetics
Family history can increase the risk, as genes may influence metabolism and fat storage.
- Hormonal Disorders
Thyroid problems, PCOS, and insulin resistance can promote weight gain.
- Emotional or Stress Eating
Stress, anxiety, and depression can trigger overeating or binge eating patterns.
Symptoms of Obesity
- Excess body fat around the waist and hips
- Breathlessness or difficulty with physical activity
- Joint pain, especially knees and back
- Fatigue and low energy
- Snoring or sleep apnea
- Increased sweating
- Low confidence and body image issues
Health Risks Associated With Obesity
