What Is Obesity? Causes, Symptoms, and Treatment Methods

Obesity is a chronic disease defined as excessive fat accumulation in the body to the extent that it threatens health.
According to the World Health Organization, obesity is one of the most rapidly increasing public health problems in both developed and developing countries.

Obesity is not merely an aesthetic concern; it is a medical condition that leads to serious health issues such as heart disease, diabetes, hypertension, joint disorders, and certain types of cancer.

How Is Obesity Measured?

Obesity is generally diagnosed using the Body Mass Index (BMI), which is calculated by dividing a person's weight by the square of their height.

BMI Classifications:
✅ 18.5 – 24.9: Normal weight
✅ 25 – 29.9: Overweight
✅ 30 – 34.9: Class 1 Obesity
✅ 35 – 39.9: Class 2 Obesity
✅ 40 and above: Morbid (Severe) Obesity

Individuals with a BMI over 30 are classified as obese.
However, body fat percentage, muscle mass, and fat distribution should also be evaluated by a healthcare professional.

What Are the Causes of Obesity?

Obesity results from a combination of genetic, environmental, and lifestyle factors.
The most common causes include:

✅ Unhealthy and irregular eating habits
✅ Sedentary lifestyle
✅ Genetic predisposition
✅ Hormonal disorders (thyroid issues, insulin resistance, PCOS)
✅ Stress, depression, and emotional eating habits
✅ Sleep disturbances
✅ Long-term use of certain medications (such as corticosteroids, antidepressants)

Modern lifestyle factors like fast-food consumption, prolonged screen time, and reduced physical activity also significantly contribute to the development of obesity.

What Are the Symptoms of Obesity?

Obesity typically progresses slowly and leads to various health complications over time.
Common symptoms include:

✅ Rapid and persistent weight gain
✅ Fat accumulation around the abdomen and waist
✅ Shortness of breath and easy fatigue
✅ Joint pain and reduced mobility
✅ Sleep apnea (breathing pauses during sleep)
✅ Skin discoloration and increased sweating
✅ Menstrual irregularities
✅ Psychological issues (loss of self-esteem, depression)

Obesity significantly reduces quality of life and lays the groundwork for serious health issues if not managed properly.

Health Risks Associated with Obesity

If left untreated, obesity can lead to numerous life-threatening conditions, such as:

✅ Type 2 Diabetes
✅ Cardiovascular diseases
✅ Hypertension
✅ Sleep apnea and respiratory problems
✅ Fatty liver disease
✅ Infertility and hormonal imbalances
✅ Certain types of cancer (such as breast, colon, and uterine cancer)

Therefore, early detection and intervention are crucial for preventing these complications.

How Is Obesity Treated?

Obesity treatment is personalized and often involves a multidisciplinary approach.
The main treatment methods include:

1. Nutrition and Dietary Counseling

✅ A personalized healthy eating plan is created under the supervision of a dietitian.
✅ Caloric restriction and balanced nutrition are targeted for weight loss.

2. Exercise and Physical Activity

✅ At least 150 minutes of moderate-intensity exercise per week is recommended.
✅ Regular exercise helps with weight loss and preserves muscle mass.

3. Behavioral Therapy

✅ Psychological support is provided to modify eating behaviors.
✅ Emotional eating and nighttime eating syndrome are addressed.

4. Medical Treatment (Medications)

✅ Appetite-suppressing or fat absorption-inhibiting medications may be prescribed under medical supervision when necessary.

5. Obesity Surgery (Bariatric Surgery)

✅ Recommended for patients with severe obesity who do not achieve success with diet, exercise, and medications.
✅ Sleeve gastrectomy and gastric bypass are the most commonly performed surgical procedures.

How to Prevent Obesity?

✅ Maintain a balanced and healthy diet; avoid processed foods.
✅ Increase daily water intake.
✅ Incorporate regular exercise into your routine.
✅ Ensure adequate sleep and maintain a consistent sleep schedule.
✅ Learn effective stress management techniques.
