Hemorrhoids – payback for walking upright

Over 400 million years of vertebrate evolution, only one species out of 60,000 species passed to upright posture, which made it possible to free the upper limbs for work, thereby developing the brain and making a breakthrough in development to homo sapiens. It is not surprising that such a sharp evolutionary leap turned into hemorrhoids for humans, both figuratively and literally. Hemorrhoids are observed in 40% of people with a sedentary lifestyle and are exacerbated by intense physical exertion, for example, when lifting weights, defecating or in childbirth. However, these same factors do not cause hemorrhoids in animals and even primates.

This paradox is resolved by the hypothesis that the transition to upright posture became the basis for the development of a unique disease. Taking into account the root cause of the pathology and personal experience, at the end of the article I give recommendations for the prevention of the development and exacerbation of hemorrhoids.

In the process of the transition of the human ancestor to upright posture, the straightening of the body occurred along the axis of the hip joint. At the same time, the pelvis turned down with its large opening, as a result of which part of the weight of the internal organs was redistributed from the anterior wall of the abdomen in quadrupeds to the pelvic floor in a bipedal person.

In addition, the transition to bipedalism freed up the hands for fine motor skills, which stimulated the development and enlargement of the brain. The larger head of a mature human fetus, in turn, caused natural selection to enlarge the inferior pelvic opening that bounds the birth canal. (Collapse)

As a result of these changes, the modern man’s pelvis is a vessel filled with innards without a solid bottom. The wide pelvic opening is closed only by the pelvic diaphragm, the muscles of which in humans bear a significant load and therefore are more developed than in animals.

In addition, keeping the torso in an upright position requires significant development of the gluteal muscles, which in humans are the largest in the body and therefore have become an attribute of sexuality, characterizing their owner as a more developed and viable sexual partner. It is important that the powerful lower bundles of the gluteal muscles are attached to the mobile tailbone, to which the main muscles of the pelvic diaphragm are attached on the opposite side, forming a pair of antagonist muscles. Thus, regular work of the gluteal muscles, for example, while walking, provides tension and elasticity of the pelvic diaphragm.
