The main reason is because the structures that intervene in the joints are deteriorating with the passage of time. That is, you are growing old. What happens in this continuous and progressive process, which accelerates from adulthood?
– There is a decrease in the elasticity and flexibility of cartilages, tendons, ligaments…
– The articular cartilage degenerates (arthrosis appears) and the bone becomes “porous”, becoming less resistant and being more prone to fractures.
– All this causes the appearance of osteoarticular pain and inflammation, which is chronic in the majority of cases and entails a great loss of quality of life.
If, in addition, you practice sports regularly, there is an added risk factor for arthrosis and joint pain to appear earlier.
Certain work activities that subject some joints to overloads maintained over time can also cause pain and functional disability.
