Conditions leading to swollen ankles and legs, such as lymphedema (lymphoedema), which is a condition of localized fluid retention and tissue swelling caused by a compromised lymphatic system, are more common than many people realise. This is also the case with Deep Vein Thrombosis (DVTs). Some of the main reasons for complaints such as this are the greater incidence of obesity and a growing geriatric population with limited mobility. Clearly, the ideal solution to help prevent this problem is increased exercise, although for many this is not an option, as conditions such as osteoporosis can make the risk of falling very hazardous indeed.

Osteoporosis is a disease of bone that leads to an increased risk of fracture. It is particularly prevalent in post-menopausal women but may also develop in men. It may also occur in anyone as a result of hormonal disorders and as a side-reaction to certain medications, especially glucocorticoids. This means that the condition has a significant impact upon quality of life and can even affect life expectancy.
