Disease associated with obesity
Obesity's Role in Diabetes
Obesity, defined as having excessive body fat, is a complex and multifactorial condition that significantly impacts health and well-being. It is associated with a wide range of diseases and health conditions, spanning from metabolic disorders to chronic illnesses. These diseases represent only a fraction of the numerous health conditions associated with obesity. Obesity is a significant public health concern that requires comprehensive prevention and management strategies, including lifestyle modifications, dietary changes, increased physical activity, behavioral interventions, and, in some cases, medical treatments. Addressing obesity and its associated diseases is essential for promoting individual health and reducing the burden on healthcare systems worldwide.
Here are some of the most common diseases
Cardiovascular Diseases
Obesity increases the risk of heart disease and stroke.
Obstructive Sleep Apnea
Obesity is a primary risk factor for obstructive sleep apnea
Depression and Anxiety
Obesity is linked to psychological disorders such as and anxiety.
How It Works
Here's a breakdown of how obesity interacts with the body to increase the risk of disease.
Obesity disrupts metabolic homeostasis, leading to insulin resistance, dyslipidemia, and inflammation. Excess adipose tissue, especially visceral fat, secretes pro-inflammatory cytokines and adipokines, which interfere with insulin signaling and promote insulin resistance. Insulin resistance, in turn, contributes to hyperglycemia, dyslipidemia, and hypertension, collectively known as metabolic syndrome, which predisposes individuals to type 2 diabetes, cardiovascular diseases, and non-alcoholic fatty liver disease (NAFLD).
Adipose tissue is not merely an energy storage depot but also an active endocrine organ that secretes hormones, cytokines, and other bioactive molecules. In obesity, adipose tissue undergoes hypertrophy and hyperplasia, resulting in dysfunctional adipocytes that produce excessive amounts of adipokines such as leptin, resistin, and tumor necrosis factor-alpha (TNF-α). These adipokines promote inflammation, insulin resistance, and endothelial dysfunction, contributing to the pathogenesis of cardiovascular diseases, insulin resistance, and atherosclerosis.
Obesity disrupts the delicate balance of hormones involved in appetite regulation, energy expenditure, and metabolism. Leptin, an adipocyte-derived hormone that regulates energy balance and appetite, becomes dysregulated in obesity, leading to leptin resistance and impaired satiety signaling. Additionally, obesity is associated with alterations in other hormones such as insulin, ghrelin, adiponectin, and cortisol, which further contribute to metabolic dysfunction, appetite dysregulation, and weight gain.
