Causes & Risk factors
Post-polio syndrome generally arises from the after effects left of having polio.
The polio virus is known to harm nerves. As the muscles are in turn controlled by nerves; the muscles also lose their strength and function. The damage is partially recovered over a period of time and but the nerves can break down over period of time and the muscles may become weak again.
The people who had polio in their teenage or in adulthood; rather than as a child tend to have post-polio syndrome. The other responsible factor may be a full recovery which makes oneself vulnerable to the post-polio syndrome.
Some doctors believe that our body’s immunity plays a role in the development of Post-polio syndrome.
