Obesity has been associated with an inflammatory state, which is chronic and low-grade inflammation, known as meta-inflammation. [6] [7] Meta-inflammation is subclinical meaning that while there is an increase in circulating pro-inflammatory factors, no clinical signs of inflammation, heat, pain, and redness, are seen with meta-inflammation.

Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution; although, only in a few cases are genes the primary cause of obesity. [4] [5]
Obesity is a major cause of disability and is correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. [2] [12] [13] Obesity has individual, socioeconomic, and environmental causes.
Obesity medicine is a field of medicine dedicated to the comprehensive treatment of patients with obesity. Obesity medicine takes into account the multi-factorial etiology of obesity in which behavior, development, environment, epigenetic , genetic , nutrition , physiology , and psychosocial contributors all play a role.

Some genetic factors and metabolic adaptations during fetal life can be claimed as etiological factors of this condition. [41] Although cardiovascular disease (CVD) is the leading cause of death and disability in the majority of the countries in Latin America, few data about regional differences on this topic has emerged.

Overweight is defined as a BMI of 25 or more, thus it includes pre-obesity defined as a BMI between 25 and 29.9 and obesity as defined by a BMI of 30 or more. [4] [5] Pre-obese and overweight however are often used interchangeably, thus giving overweight a common definition of a BMI of between 25 and 29.9. There are, however, several other ...
For the first time in over a decade, obesity rates in the United States may finally be heading in the right direction and new weight loss drugs like semaglutide could be part of the reason why. A ...
Obesity has been found to contribute to approximately 55% of cases of type 2 diabetes; [10] chronic obesity leads to increased insulin resistance that can develop into type 2 diabetes, [11] most likely because adipose tissue (especially that in the abdomen around internal organs) is a source of several chemical signals, hormones and cytokines, to other tissues.
