Piles (or Haemorrhoids) are a very common ailment that may affect men or women at any age. These are caused due to continuous high pressure in the veins. Other causes include constipation, excessive straining during bowel movements and persistent diarrhea. Family inheritance is also seen. Women are more susceptible to piles in pregnancy as the pressure from the growing uterus restricts the blood flow in the pelvis. Lifestyle factors also have a contributory effect.
