The long-term effects of obesity on health can be severe and multifaceted. Increased body weight is associated with a higher risk of developing chronic conditions like diabetes, heart disease, and certain cancers. Obesity can also lead to mental health issues, such as depression and anxiety, due to social stigma and decreased self-esteem. Furthermore, it may impact mobility and increase the risk of osteoarthritis and sleep apnea. Addressing obesity through lifestyle changes is crucial for mitigating these long-term health complications.
