Overweight and obesity defnies the abnormal or excessive accumulation of fat, posing health risks. An individual is considered overweight with a BMI exceeding 25, and obese with a BMI over 30. This problem has reached epidemic levels, with more than 4 million fatalities annually attributed to overweight or obesity in 2017, as reported by the global burden of disease.
The rates of overweight and obesity persistently rise among both adults and children. Between 1975 and 2016, the occurrence of overweight or obese children and adolescents aged 5–19 years surged more than fourfold globally, escalating from 4% to 18%.
Obesity represents one side of the dual challenge of malnutrition, with more individuals being obese than underweight in nearly all regions except sub-Saharan Africa and Asia. Formerly perceived as a common problem to other nations, overweight and obesity are increasingly common in low- and middle-income countries, particularly in urban areas. The majority of overweight or obese children reside in developing nations, where the rate of escalation surpasses that of developed countries by over 30%.
Osteoarthritis is a very common type of arthritis which is a degenerative joint condition. It causes pain, swelling and stiffness, affecting a person’s ability to move freely, especially if a person is gaining too much weight or being obese. Being merely 10 pounds overweight imposes an additional 15 to 50 pounds of pressure on your knees, heightening the risk of developing or exacerbating osteoarthritis (OA). Carrying excess body weight not only burdens joints but also accelerates cartilage deterioration in OA.
Pressure on Joints – Extra weight strains joints, amplifying stress and the risk of damage. With osteoarthritis and joint misalignment, activities such as stair climbing or squatting exacerbate pressure, potentially compromising joint health, especially in overweight individuals.
Inflammation – Fat cells release chemicals that cause inflammation
Disease Progression – Osteoarthritis progresses more rapidly and presents with greater severity in individuals who are obese compared to those with lower body weights. Overweight or obese individuals have a higher likelihood of requiring hip or knee replacement surgeries, along with experiencing increased post-operative complications and inferior outcomes. The objective is to mitigate weight and inflammation prior to surgery.
Several approaches leading to effective weight loss and its sustained maintenance also serve as preventive measures against obesity. Enhancing dietary patterns and boosting physical activity are crucial components in obesity prevention. Recommendations for adults include:
Overweight and obesity present significant health challenges, particularly in relation to joint health and the development of osteoarthritis. The strain placed on joints, coupled with inflammatory responses and accelerated disease progression, underscores the importance of weight management and preventive measures. By adopting healthy eating habits, engaging in regular physical activity, and practicing portion control, individuals can mitigate the risk of obesity and its associated complications. Through collective efforts to promote lifestyle changes and raise awareness, we can work towards a healthier future, where the burden of obesity-related conditions is alleviated, and individuals can enjoy improved overall well-being. Remember, small steps towards a healthier lifestyle can lead to significant long-term benefits for both joint health and overall health.
