Obesity negatively affects respiratory functions by reducing lung capacity by 20-30%. If additional conditions such as smoking or chronic bronchitis are present, severe breathing difficulties may occur. One of the most significant effects of obesity is its increased risk of type 2 diabetes. Obese individuals have a 40 times higher risk of developing diabetes compared to individuals of normal weight. This risk is observed to be very high in obese individuals over 40 with a family history of diabetes. Furthermore, obesity increases the risk of hypertension by 4-5 times. Along with high blood pressure, the likelihood of heart disease and heart attack also rises by 3-4 times. Obesity increases the risk of gallstone formation by 4-5 times compared to non-obese individuals, and also significantly raises the probability of fatty liver. Beyond physical health problems, obesity can negatively impact individuals' quality of life. Dissatisfaction with body image can increase the risk of depression and worsen the course of existing depression.
