Is Small Intestinal Bacteria Overgrowth Genetic?

Small Bacteria Intestinal Overgrowth refers to a condition in which there is an overgrowth or an overabundance of harmful, potentially pathogenic bacteria present in the small intestines. This condition is a result of improperly functioning muscles sucking harmful bacteria’s that should, in a healthy functioning digestive tract, remain inside the large intestines or the colon.

Small Intestinal Bacteria Overgrowth

The way the digestive tract works is that it uses a series of muscles to push or force food downward throughout the body. These muscles guide food and beverages that we have consumed down through the stomach into the small intestines to be further broken down and absorbed into the body. The waste is then forced further downward into the large intestine where it will make its final destination to the colon. During this process these properly functioning muscles will push harmful bacteria out of the small intestines and into the colon. However, in a digestive tract that is not properly functioning, for whatever reason, these muscles are not able to efficiently remove all of the harmful bacteria and furthermore are not able to prevent it from creeping back into the small intestines from the large intestines (or colon) resulting in a colonization and overgrowth of harmful and potentially pathogenic bacteria in the small intestines.
Small Bacteria Intestine Overgrowth itself is not said to be genetic. However, certain conditions that inevitably lead to Small Bacteria Intestinal Overgrowth can be, such as Celiac Disease and Scleroderma. Experts say that they are certain individuals that are predisposed to suffering from Small Bacteria Intestinal Overgrowth due to specific risk factors. Of which researchers have categorized into three main groups: 1) genetic disorders of the immune system, 2) anatomical changes that ultimately lead to stasis or disorderly motility, and 3) conditions that can cause an excessive amount of harmful bacteria to travel back up from the large intestine (or colon) back into the small intestine.
