Overweight and obese people have a higher risk for developing hemorrhoids. This occurs because the weight places too much pressure on the pelvic region and exerts continual strain on the veins in the rectum and anus. When the digestive system is ready to eliminate feces, blood engorges these veins to propel the solid waste from your body. This physiological change places additional pressure on these overstressed veins that leads to further swelling and ultimately scarring. If this is not corrected you will get thrombosed, prolapsed or bleeding hemorrhoids.
People with excess weight also tend to be sedentary and have poor diets. Sitting for prolonged periods and low fiber intake are lifestyle factor that can cause or aggravate hemorrhoids symptoms. Losing weight, adopting a more active lifestyle and a healthy diet takes the excess pressure off your lower abdomen and the overstressed veins. These lifestyle changes can improve your hemorrhoid symptoms.
