Introduction 

Obesity is a growing health concern affecting millions of people worldwide. It occurs when a person carries excess body fat, which can lead to serious health complications if left unmanaged. Recognising the symptoms of obesity early can help in taking timely action to improve overall health.

In this article, we’ll discuss the key indicators of obesity, its causes, health risks, and practical steps to manage it effectively.

What Are the Common Symptoms of Obesity?

Obesity is not just about weight—it’s about how excess fat affects your body. Some key symptoms include:

1. Increased Body Weight

  • A Body Mass Index (BMI) of 30 or above is classified as obese. (BMI is calculated using height and weight.)

  • Waist circumference exceeding 40 inches (102 cm) in men and 35 inches (88 cm) in women may indicate obesity.

2. Difficulty in Physical Activities

  • Feeling out of breath after minor exertion (e.g., climbing stairs, walking short distances).

  • Joint pain, especially in the knees and hips, is due to excessive weight pressure.

3. Fatigue and Low Energy

  • Feeling tired even after minimal activity.

  • Poor sleep quality due to conditions like sleep apnea.

4. Skin Problems

  • Darkened skin patches (acanthosis nigricans) in body folds (neck, armpits, groin).

  • Skin infections are due to excessive sweating and friction.

5. Psychological Effects

  • Low self-esteem, anxiety, or depression due to body image concerns.

  • If you notice these signs, it’s important to consult a doctor for proper evaluation and guidance.

What Causes Obesity?

Obesity doesn’t happen overnight—it’s often a result of multiple factors:

1. Unhealthy Eating Habits

  • Consuming high-calorie, processed, and sugary foods frequently.

  • Overeating or emotional eating due to stress.

2. Lack of Physical Activity

  • Sedentary lifestyle with minimal exercise.

  • Long hours of sitting (office work, screen time).

3. Genetics and Hormonal Factors

  • Family history of obesity.

  • Hormonal imbalances (e.g., thyroid issues, PCOS).

4. Poor Sleep and Stress

  • Lack of sleep disrupts metabolism and increases hunger hormones.

  • Chronic stress leads to overeating.

5. Medical Conditions & Medications

  • Conditions like hypothyroidism, Cushing’s syndrome, or insulin resistance.

  • Certain medications (steroids, antidepressants) may contribute to weight gain.
