While disc degeneration cannot be reversed, there is evidence that exercise, lifestyle modifications, and careful management of back pain can help you live a better life. Disc degeneration is the leading cause of disability in people under 45 years old. It affects approximately 5% of the population over the age of 20 and almost half of all persons by 40 years old. Disc degeneration results in a loss of disc height and ligamentous laxity, which in turn increases your risk of developing spinal stenosis and other spine-related problems. However, there are things you can do to prevent it from progressing. Exercise and maintain a healthy weight are both important in preventing disc degeneration. A study conducted at the University of Michigan found that individuals who participated in a program designed to promote physical activity and improve diet saw their rate of disc degeneration reduced by 21%. Another study published in the Journal of the American Medical Association showed that being overweight or obese increases your risk of disc degeneration by about 50%. Sleep is also crucial for maintaining good health and helping you fight off disease. In a study published in 2004, researchers investigated the relationship between sleep quality and disc degeneration. They concluded that poor sleep quality is associated with increased rates of disc degeneration.
