Increased joint stress from the abdomen might result in diseases like osteoarthritis.

It's correct. Excess weight, especially abdominal weight, can strain knees and hips. Stress can cause osteoarthritis and other musculoskeletal issues. Obesity can damage joints and cause osteoarthritis:

Weight increases joint stress, especially in the lower extremities. Mechanical load on weight-bearing joints accelerates cartilage deterioration.

Chronic inflammation: Obesity causes systemic inflammation. Systemic inflammation can damage cartilage and cause osteoarthritis.

Increased body weight can change joint mechanics, causing aberrant movement patterns and uneven force distribution. This can cause joint deterioration and osteoarthritis.

Fat cells create hormones and cytokines that can cause inflammation and affect joint health. These chemical imbalances may cause osteoarthritis.

Obesity is linked to insulin resistance, which impairs cell response to insulin. Insulin resistance may cause osteoarthritis and inflammation.

Preventing osteoarthritis and treating its symptoms requires weight management through food and exercise. Joint health, mechanical stress, and inflammation can be improved by losing weight. 

A healthy lifestyle can also improve well-being and minimize obesity-related diseases. Joint health and weight concerns should be discussed with healthcare specialists for personalized advice and treatment.
