M35.7: Hypermobility syndrome

Your connective tissue is far weaker than that of other people.

There is connective tissue in many parts of the body. There is connective tissue beneath the skin, between the muscles, in tendons and in organs. Connective tissue can be both tight and elastic. In joints, connective tissue ensures that bones are firmly attached, yet mobile at the same time.

When there is a weakness in the connective tissue, it is not as firm as usual. As a result, the joints may be too mobile so that they become unstable. The skin may also be particularly elastic.

  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
