Common diseases in old age
According to the UN, the population of elderly persons is the fastest growing around the world and the number of elderly people by 2050 will be close to 2 billion.
The World Health Organisation has taken the initiative to draw attention to ageing as this imposes many challenges for individuals and authorities, like coping with health care, employment, housing, social security and other issues concerning the elderly.
Aging is an inevitable process and many factors like genes, lifestyles, diet and environment determine longevity. Though life expectancy has increased in modern times thanks to advances in science, technology and medicine, the grinds of daily life take a heavy toll on our bodies.
For most of us, taking care of our health is the last thing on our mind as we are too busy. Eventually negligence takes its toll on our body and manifests itself through a serious illness or in rapid physical deterioration in old age.
As humans grow older, physical conditions decline which lead to many illnesses and ailments. Some of the common health problems affecting the aged are:
