Prolapsed Grade IV Hemroids 

Western Diet
Although it is very common in Western countries, hemroids is actually rare in cultures that eat a fiber-rich diet. A typical Western diet is rich in refined flour, sugar, animal protein, and fiber-depleted carbohydrates, whereas Asian and African diets are rich in natural grains, plant fibers and roughage.

This leads people to think that diet plays a big role: foods that are lacking in fibers actually create stool that is harder to pass. This results in straining during a bowel movement, and thus hemroids.

Indeed, there is some evidence that there is a direct relationship between the amount of fiber in the food, the time it requires to ingest and eliminate the food, as well as the weight and consistency of stool. For example, a typical African villager easily passes about 400 to 500 grams of moist stool approximately 35 hours after eating. A typical Westerner, however, passes 150 grams of stool approximately three to five days after eating!

Interestingly, the incidence of hemroids often increase as the society becomes more affluent and its diet becomes more Westernized.

You may ask: if it's so bad, why does Western food processing get rid of fiber in the first place? Fiber is refined out of flour and other foods for two main reason: consumer convenience and profit for the food manufacturers. It turns out that without the fibers, food is easier to chew and can be swallowed more easily. Also, it takes less digestive gastric juices to process, thus making more room in the stomach for food. This means that consumers can actually eat more of processed food, therefore increasing the profit of food manufacturers.

Indeed, prior to the introduction of the steel roller mills, which deplete fibers from flour, in the 1880s, hemroids were quite rare even in Western countries.

Pregnancy
Another of the most common causes of hemroids in women is pregnancy: the extra weight of the uterus adds great pressure on the rectal veins. For women who already have hemroids, pregnancy can definitely make their hemroids condition worse.

Even women who do not develop hemroids during pregnancy can still get them because of long and arduous labor and delivery, or because of constipation that arise after childbirth. For example, in the days and weeks after vaginal delivery, some women regularly postpone bowel movements because of tenderness in the Excretory Orifice and periExcretory Orifice area.
