Usually, bleeding occurs for a few days and stops only to reappear at a later date which may be in days, months or even in years. For some, it may bleed continuously. Once the disease starts it progresses to severity in a matter of time. However, the progression varies from person to person. For some it happens rapidly, for others it may be slow.
Piles runs in families.
So if the father or mother suffers from the disease, chances of their children getting it is high. Straining while passing stools is the most common cause for piles. Straining exerts excessive pressure over the blood vessels, which then transform themselves into piles over a period of time. So doctors advise patients to include lots of vegetables and fruits in their diet to enable easy passage of stools. Cancer growth hidden inside may present itself as piles since it blocks the blood vessels.
