What is a common physical health issue caused by obesity?

Increased pressure on joints is a common physical health issue caused by obesity because excess weight puts additional stress on the body's joints, particularly those in the lower body such as the knees and hips. This increased pressure can lead to discomfort, pain, and conditions such as osteoarthritis, where the cartilage that cushions the joints wears down over time. The added weight makes it more challenging for joints to function properly, often leading to decreased mobility and difficulties in performing everyday activities.

The other options do not accurately reflect the effects of obesity. For instance, increased lung capacity and improved metabolic rate are not typically associated with obesity; in fact, obesity often leads to decreased lung function and metabolic issues. Additionally, obesity is linked to an increased risk of heart disease rather than a reduced risk. Understanding the impact of obesity on joint health is crucial for addressing overall physical well-being and developing effective health interventions.
