These conditions are seldom passed on directly from parent to child, although some families seem to be susceptible to certain types of arthritis.
Although the exact causes of arthritis are unknown, regular exercise and maintaining a healthy bodyweight reduce the risk of developing osteoarthritis. Avoiding chronic stress on joints from over-use (e.g. during certain work-related activities) can also reduce the likelihood of developing arthritis. Some preventive measures have proven to be beneficial for patients who already have arthritis, e.g. charges in lifestyle may help to stop deterioration of their joints and avoid complications of the disease.
