Introduction
Overweight and obesity have become major global health concerns. They occur when a person has excessive body fat that may negatively affect their health. These conditions are often caused by an imbalance between the calories consumed and the calories burned through physical activity.
According to health experts, the number of people affected by overweight and obesity has increased significantly in recent decades due to changes in lifestyle, diet, and physical activity patterns.
Maintaining a healthy body weight is important because obesity increases the risk of many chronic diseases, including heart disease, diabetes, and hypertension. Fortunately, many cases can be prevented through healthy lifestyle choices.
What Are Overweight and Obesity?
Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. A common method used to measure body weight status is the Body Mass Index (BMI).
BMI is calculated by dividing a person's weight (in kilograms) by the square of their height (in meters).
BMI Categories
- Underweight: BMI below 18.5
- Normal weight: BMI 18.5 – 24.9
- Overweight: BMI 25 – 29.9
- Obesity: BMI 30 or higher
Although BMI is a useful screening tool, other factors such as body composition, muscle mass, and overall health should also be considered.
Causes and Risk Factors
Several factors contribute to overweight and obesity. These may include lifestyle habits, environmental influences, and genetic factors.
Common causes and risk factors include:
- Unhealthy diet high in calories, sugar, and fats
- Lack of physical activity
- Sedentary lifestyle such as long hours of sitting
- Emotional eating or stress-related eating
- Genetic predisposition
- Poor sleep habits
- Hormonal imbalances
Addressing these factors can help reduce the risk of gaining excess weight.
Health Risks Associated with Obesity
Obesity is associated with several serious health conditions that can affect quality of life and increase the risk of premature death.
Major health risks include:
- Heart disease and stroke
- Type 2 diabetes
- High blood pressure
- Chronic kidney disease
- Joint problems and arthritis
- Sleep apnea
- Certain types of cancer
Maintaining a healthy weight is therefore important for long-term health and well-being.
How to Prevent Overweight and Obesity
