What Is Obesity?
Obesity is a medical condition characterized by excessive body fat that increases the risk of health problems. While weight alone doesn’t determine health, excess fat—especially around the abdomen—can interfere with normal body functions.
Why Obesity Is a Global Concern
Obesity rates have been rising worldwide due to modern lifestyles, poor diet habits, and reduced physical activity. It’s now considered a major public health issue affecting both developed and developing countries.
Understanding BMI and Body Composition
Body Mass Index (BMI) is commonly used to assess obesity, but body composition and fat distribution also play a crucial role in determining health risks.
Health Risks Associated with Obesity
Heart Disease
Obesity increases cholesterol levels, blood pressure, and inflammation—major factors contributing to heart disease.
Type 2 Diabetes
Excess weight can make the body resistant to insulin, leading to elevated blood sugar levels.
High Blood Pressure
Overweight individuals often experience increased blood pressure, which strains the heart and arteries.
Stroke
Blocked blood vessels caused by fat buildup increase the likelihood of stroke.
Respiratory Issues
Excess fat around the chest and abdomen can make breathing difficult and increase the risk of sleep apnea.
Joint and Bone Problems
Extra weight puts pressure on joints, contributing to arthritis and chronic pain.
Mental Health Challenges
Obesity is linked with depression, anxiety, and low self-esteem—often caused by societal pressure and physical limitations.
Certain Types of Cancer
Research suggests obesity may increase the risk of cancers such as breast, colon, and endometrial cancer.
Major Causes of Obesity
Poor Diet and Overeating
Consuming calorie-dense foods such as fast food, sugary drinks, and processed snacks contributes significantly to weight gain.
Lack of Physical Activity
Sedentary lifestyles reduce calorie burn, making it easier to gain excess weight.
Genetics and Family History
Genes can influence metabolism, appetite, and fat distribution, increasing obesity risk.
Metabolic Factors
Some people naturally burn fewer calories at rest, making weight gain easier.
Hormonal Imbalances
Conditions like hypothyroidism and hormonal changes can lead to weight gain.
Psychological Factors
Stress, emotional eating, and mental health conditions can influence food choices and appetite.
Medications and Medical Conditions
Certain medications—such as antidepressants, steroids, and diabetes drugs—may cause weight gain.
Environmental and Lifestyle Factors
Unhealthy eating environments, lack of access to healthy foods, and busy schedules affect weight.
Signs and Symptoms of Obesity
Visible Physical Changes
Excess body fat, especially around the waist, is a clear indicator.
Difficulty Performing Physical Activities
Walking, climbing stairs, or exercising may become challenging.
Fatigue and Low Energy
Carrying extra weight puts strain on the body, often leading to chronic tiredness.
How Obesity Is Diagnosed
BMI Measurement
A BMI of 30 or above is generally considered obese.
Waist Circumference
A large waist size indicates high belly fat, which poses greater health risks.
Blood Tests and Medical Evaluation
Doctors may check cholesterol, blood sugar, and thyroid function to understand underlying causes.
