Today, obesity has become a global health challenge. This condition is common among people of all ages. Along with targeting your physical appearance, obesity also impacts your body's internal system. For people suffering from obesity, the very first step is to thoroughly understand the condition and its depth.
What Is Obesity?
Obesity is a long-term health condition that makes it a chronic disease. It is caused when excessive fat accumulates in your body. The effects increase the risk of adverse health issues. Most commonly, obesity is assessed by the Body Mass Index (BMI).
Normal weight: BMI of 18.5–24.9
Overweight: BMI of 25–29.9
Obese: BMI of 30 or higher
BMI is not the only factor that indicates obesity. Body composition, fat distribution, and metabolic health also play an important role.
What is the Root Cause of Obesity?
The biggest misconception about obesity is that it happens when you eat more than your capacity. But the truth is, obesity is a multifactorial condition influenced by biological, environmental, and behavioral factors. Here are some root causes:
Dietary Pattern
Modern diets like processed foods, sugary beverages, and calorie-dense meals lack fiber and essential nutrients, leading to overeating that significantly increases weight.
Physical Inactivity
About 60–80% of the global population follows a sedentary lifestyle — little to no physical activity or prolonged sitting. This reduces energy expenditure and leads to weight gain.
Genetics & Biological Factors
Many individuals are predisposed to store fat genetically. Hormonal imbalances — including insulin, leptin, and ghrelin — can disrupt hunger and metabolism.
Psychological Factors
Stress, anxiety, depression, and emotional eating often contribute to unhealthy eating patterns and result in weight gain.
Health Risks Associated With Obesity
According to research, obesity can cause over 200 health issues, some of them being life-threatening diseases like cancer. When left unmanaged, it can become significantly worse. The underlying driver is metabolic change — altered metabolism increases the risk of conditions including:
Type 2 diabetes
Cardiovascular disease and high blood pressure
Sleep apnea and breathing problems
Joint pain and mobility issues
Certain cancers
Depression and reduced quality of life
Modern Medical Solutions
Lifestyle changes are the foundation of any weight loss journey, but for many people they are not enough on their own. FDA-approved GLP-1 medications — such as semaglutide and tirzepatide — work by regulating appetite, slowing gastric emptying, and improving insulin sensitivity, helping patients achieve meaningful, sustained weight loss under medical supervision.
Evolve Medical Services offers personalized, doctor-supervised GLP-1 weight loss programs at our San Diego and Riverside clinics. Contact us for a free consultation.
