Straining at Stool: A Hidden Cause of Venous Insufficiency

Venous insufficiency, commonly associated with prolonged standing or sedentary lifestyles, can also stem from a surprising source: excessive straining during bowel movements. Chronic constipation increases intra-abdominal pressure, forcing veins in the rectum and lower limbs to endure added stress. Over time, this pressure weakens vein walls and damages valves, impairing blood flow. Straining can also trigger hemorrhoids, which further exacerbate venous problems. Preventing this condition requires addressing constipation through a high-fiber diet, adequate hydration, and proper bowel habits. Recognizing the link between straining and venous insufficiency underscores the importance of maintaining digestive health to protect vascular well-being.
