Last Updated: October 31, 2026
Joint hypermobility syndrome is a condition where your joints are unusually flexible, often referred to as being "double-jointed." This happens because the ligaments that support your joints are weaker than usual. The weakness is due to a difference in the collagen, a key protein that strengthens these ligaments. This condition is believed to be part of a broader group of hypermobility disorders, including Ehlers-Danlos syndrome. It tends to run in families and cannot be prevented from developing. While there's no cure, the main approach to managing the syndrome involves strengthening muscles around the joints. This helps to provide better support and protection, reducing pain and the risk of dislocations.
