Grade 3 piles develop when long-term pressure stretches the pelvic blood vessels and breaks down the connective tissues anchoring the hemorrhoidal cushions inside the anal canal.
Primary Causes
-
Chronic Constipation and Straining: Forcing hard stools requires intense expulsive pressure, which shears and pushes the vascular cushions downward out of the anus.
-
Chronic Diarrhea: Frequent bowel movements cause recurrent inflammation, sphincter muscle spasms, and continuous pelvic vascular congestion.
Contributing Risk Factors
-
Low-Fiber Diet: A lack of fiber creates small, dense stools that are highly difficult to pass without straining.
-
Sedentary Lifestyle: Prolonged sitting—especially on the toilet—causes blood to pool in the lower rectum, weakening venous walls over time.
-
Pregnancy and Childbirth: The growing uterus exerts direct mechanical pressure on pelvic veins, while the intense straining of vaginal delivery can acutely force tissue into a prolapsed state.
-
Obesity: Carrying excess weight permanently elevates intra-abdominal pressure, placing constant strain on the pelvic floor.
-
Aging: Natural aging breaks down collagen and elastin, causing the supportive tissues in the anal canal to thin and weaken.
-
Family History: A genetic predisposition to weak venous walls or inherently loose connective tissue makes individuals more susceptible to advanced stages of piles.
