A mass of dilated, tortuous veins in the anorectum involving the venous plexuses of that area constitutes hemorrhoids. Usually there is no detectable cause, but they may occur because of blockage to the passage of blood draining the intestines. They are also associated with constipation and sometimes develop during pregnancy, when growing uterus hampers venous return from pelvic organs.

Anemia usually develops due to persistent loss of blood. Hemorrhoids can be effectively cured with Ayurvedic treatment, unless they are large 3rd or 4th degree ones or get additionally complicated with thrombosis or strangulation, wherein surgical intervention is required.
