Maintaining a healthy weight is a key factor in preventing arthritis and managing its symptoms. Excess weight can significantly impact the joints, particularly those that bear the most weight, such as the knees, hips, and lower back. Experts emphasize that obesity not only increases the likelihood of developing arthritis but also accelerates its progression. Here’s how managing weight plays a vital role in both prevention and treatment.
Obesity and Arthritis: The Connection
Dr. Satya Narain Saroha, Director of Orthopaedics & Joint Replacement at Max Super Speciality Hospital, Shalimar Bagh, explains that obesity is a major risk factor for the development and progression of arthritis, particularly knee arthritis. People who are obese are at a far greater risk of developing arthritis compared to individuals with a healthy weight. This is especially true in the Indian subcontinent, where knee arthritis is more common than hip arthritis. Excess body weight places undue stress on the knee joints, accelerating joint deterioration.
“The excessive strain from obesity leads to weaker muscles around the knee, further contributing to the development of arthritis,” says Dr. Saroha. Not only does obesity increase the likelihood of developing arthritis, but it also causes the condition to progress more rapidly. A person with a higher body mass index (BMI) tends to experience more severe arthritis symptoms, including greater pain and mobility issues, compared to someone with a lower BMI.
The Impact of Weight on Joint Health
Dr. Indrajit Agrawal, Clinical Director of Rheumatology at Marengo Asia Hospital, Gurugram, highlights that maintaining a healthy weight is crucial in preventing arthritis, particularly osteoarthritis, which often affects weight-bearing joints like the knees, hips, and lower back. “Cartilage, the tissue that cushions the joints, ages more rapidly in overweight individuals due to the increased strain on these joints,” Dr. Agrawal explains. Over time, this can lead to discomfort, swelling, and a reduced range of motion.
“Every pound of excess weight puts four pounds of pressure on the knees,” says Dr. Agrawal. This magnified strain accelerates joint wear and tear, hastening the onset of arthritis. By managing weight through a balanced diet and regular physical activity, such as swimming, walking, or cycling, people can significantly reduce the load on their joints, thus delaying or even preventing the development of arthritis.
Weight Loss and Symptom Relief
For individuals who already suffer from arthritis, weight loss can significantly alleviate symptoms. Dr. Saroha emphasizes that losing weight reduces the strain on the joints, resulting in less pain and improved mobility. However, for patients with severe or disabling arthritis, engaging in weight-loss exercises may not be feasible. In such cases, surgical intervention, such as knee or hip replacement, might be necessary to restore mobility.
“Surgery helps patients regain the ability to be physically active, which in turn allows them to work on weight loss and improve their overall condition,” Dr. Saroha notes. In some instances, staged surgeries are performed—first to improve joint function, followed by weight loss efforts through physical activity.
The Role of Diet and Lifestyle Changes
Alongside physical activity, dietary changes are crucial for managing both obesity and arthritis. Dr. Saroha advises that a diet rich in proteins and fiber can help reduce calorie intake and promote weight loss. “Maintaining a healthy diet supports joint health and improves the overall quality of life for arthritis patients,” he says.
Dr. Agrawal adds that weight management also reduces the risk of related health conditions like diabetes and heart disease, which are more common in people with arthritis. “By lowering pain, improving joint function, and preventing associated diseases, managing weight can significantly enhance the quality of life for those with arthritis,” he concludes.
In summary, weight management is a cornerstone of both arthritis prevention and treatment. By maintaining a healthy weight, individuals can reduce the risk of developing arthritis, slow its progression, and improve their joint function, leading to better mobility and a higher quality of life.
