Wear and tear on Joints
Joint pain - an almost inevitable result of ageing, coupled with wear and tear on joints. Why does this happen?
The articulating surfaces of the bones (the ends of the bones that come together forming the joint) are covered in articular cartilage and are bathed in Synovial Fluid - "joint oil". In a normal healthy joint the articular cartilage is smooth and the synovial fluid is of sufficient high quality to provide adequate lubrication.
Cells, called Chondrocytes in the articulating cartilage, help to repair and regenerate the cartilage as it wears away. Glucosamine, synthesised in the body from glucose, provides the building blocks necessary for chondrocytes to repair the damage.
What can go wrong with joints?
Articular cartilage is one of the first tissues to age and has relatively poor powers of regeneration because of the poor blood supply to the area, even in a healthy person. The delicate balance between wear and renewal can be easily upset - a strain, a slip or fall, repeated heavy use or even an old injury to the joint can start a cycle of events that will lead to progressive degeneration of the joint.
The natural reaction of joints to a strain, injury or wear and tear is to become inflamed, whether visibly so or not - a greater amount of synovial fluid is produced (which is often of poorer quality) and enzymes can be produced which actually degrade the cartilage and synovial fluid. This causes sustained, if not greater, inflammation... a self perpetuating cycle leading to degeneration of the joint as the body cannot produce enough glucosamine to keep up to the rate of repair and renewal that would be necessary. This is especially true as we get older with the slowing down of body systems that comes with age.
A glucosamine sulphate supplement can help
Many people have reported greatly improved mobility, as well as pain relief, with a good glucosamine supplement.
