Obesity: a complex medical condition that goes beyond body weight.

Obesity is a chronic condition characterized by excessive accumulation of body fat that can negatively affect overall health. It is not simply a cosmetic concern, but a multifactorial medical issue that increases the risk of developing serious diseases such as type 2 diabetes, high blood pressure, cardiovascular disease, and certain types of cancer.

Today, obesity is recognized as one of the leading public health challenges worldwide.

What is obesity?

Obesity is commonly defined using the Body Mass Index (BMI), which relates a person’s weight to their height. A BMI of 30 or higher is generally classified as obesity.

However, BMI does not always accurately reflect body fat distribution or overall health status. For this reason, healthcare professionals also evaluate waist circumference, medical history, lifestyle habits, and other clinical indicators.

Causes of obesity

Obesity does not have a single cause. It results from a combination of factors, including:

• Poor diet: excessive intake of calories, sugar, and saturated fats

• Sedentary lifestyle: lack of regular physical activity

• Genetic factors: inherited predisposition

• Hormonal and metabolic factors: conditions affecting appetite and metabolism

• Psychological factors: stress, anxiety, and depression influencing eating behaviors

• Environmental and lifestyle factors: easy access to processed foods and unhealthy routines

Health risks associated with obesity

Obesity significantly increases the risk of multiple health complications, including:

• Type 2 diabetes

• High blood pressure (hypertension)

• Cardiovascular disease

• Sleep apnea

• Joint problems

• Fatty liver disease

• Certain types of cancer

It can also affect mental health, contributing to low self-esteem, anxiety, and depression.

Diagnosis

Obesity is diagnosed through a comprehensive medical evaluation, which may include:

• Body Mass Index (BMI) measurement

• Waist circumference assessment

• Complete medical history

• Evaluation of diet and physical activity habits

• Laboratory tests when necessary

A personalized approach is essential, as each patient presents different risk factors and health conditions.

Treatment and management

Treatment for obesity should always be individualized and supervised by healthcare professionals. Main strategies include:

1. Lifestyle changes

• Balanced, portion-controlled nutrition

• Regular physical activity

• Improved sleep habits

• Stress management

2. Psychological support

Emotional and behavioral support is essential to help patients develop long-term healthy habits.

3. Medical treatment

In some cases, healthcare providers may prescribe medications to assist with weight management under strict supervision.

4. Bariatric surgery

For patients with severe obesity or related medical conditions, surgery may be considered when other treatments have not been effective.

Prevention

Prevention plays a key role and is based on healthy habits established early in life:

• Balanced diet rich in fruits, vegetables, and lean proteins

• Regular physical activity (at least 150 minutes per week)

• Limiting sugar and ultra-processed foods

• Nutrition education

• Regular medical checkups

Obesity is a complex disease that requires a comprehensive and ongoing medical approach. With proper support, lifestyle changes, and professional care, patients can significantly improve their health and quality of life.
