Joint hypermobility: What causes loose joints?
Medically reviewed by Drugs.com. Last updated on Aug 11, 2020.
Loose joints is a term that's sometimes used to describe hypermobile joints. Joint hypermobility — the ability of a joint to move beyond its normal range of motion — is common in children and decreases with age.
Having a few hypermobile joints isn't unusual. In most people, joint hypermobility causes no problems and requires no treatment.
But in some people, hypermobility causes joint pain and may result in a higher incidence of dislocations and sprains. Your doctor might suggest physical therapy to help strengthen the muscles surrounding these joints.
See your doctor if your loose joints also cause you pain. Rarely, joint hypermobility is a sign of a more serious disorder, such as Ehlers-Danlos syndrome or Marfan syndrome.
