Inside the body, the gut and the intestines make sure that everything is working properly. The gut and intestinal system make sure that the consumed food is being digested and the nutrients from the food are being transported all over the entire body. The gut system makes sure that the body is being supported by regulating the growth, metabolism, and immune support of all the organ systems and that each of the systems is doing its job. When harmful pathogens enter the body and start to disrupt the gut system, it can lead to chronic gut disorders over time if it is not treated right away. In this 2 part series, we will be taking a look at how SIBO and SIFO affect the gut as well as their symptoms. In Part 2, we will be taking a look at different treatments for SIBO and SIFO to optimize gut health. By referring patients to qualified and skilled providers who specialize in gastroenterology services. To that end, and when appropriate, we advise our patients to refer to our associated medical providers based on their examination. We find that education is the key to asking valuable questions to our providers. Dr. Alex Jimenez DC provides this information as an educational service only. Disclaimer

What Is SIBO?
SIBO, or small intestinal bacterial overgrowth, is a condition where an abnormally large number of bacteria (at least 10,000 bacteria per ml of duodenal aspirate) are present in the small intestines. In the small intestines, as research shows, when the food is being digested, gastric acids and biles are being destroyed. The bacteria are being prevented from entering through the intestines, providing optimal function. When there is an abundance of excessive bacteria in the small intestines causing problems, this is known as SIBO. SIBO is a commonly known gastrointestinal disorder that affects millions of individuals. Other research studies have shown that the common risk factors for SIBO include disturbances in the small bowel anatomy and motility in the gut system. The gut system needs the intestines to regulate the good bacteria for the stomach and the other organs to be functional. When SIBO starts to cause the bacterial growth to be excessive, it can cause many gut disorders to pop up and cause many disturbances to the gut and the body.
The human body requires the balance of beneficial flora in the gut to maintain optimal function of the body through a complex series of chemical and mechanical operations. Research studies show that it is normal to have bacteria living in the intestines. Still, when there is an overabundance of bacteria growing in the intestines, the harmful bacteria can overtake and overwhelm the good bacteria, causing an upset to the digestive system. The harmful bacteria will begin to feed on the consumed food products meant for the good bacteria. Some of the symptoms that are from SIBO include:
How SIBO Affects The Gut
The small intestines in the gut system ensure that the nutrients and the food mixed with digestive juices are being absorbed into the bloodstream and transported throughout the entire body. When SIBO is developing in the small intestines, research studies have shown that stagnant food in the small intestines is an ideal breeding ground for harmful bacteria to produce toxins and interfere with the absorbed nutrients. SIBO can steal the nutrients from the consumed, digested food. If it is not treated right away, the harmful bacteria will begin to overproduce and take over the beneficial bacteria. This will cause many gut issues and disorders to the gut system causing the body to be dysfunctional.
What Is SIFO?
When there is an abundance of fungal growth in the intestines can lead to many disorders in the gut, just like SIBO. SIFO or small intestinal fungal overgrowth is a condition where abnormally large numbers of fungi/yeast are found in the small bowel that is associated with gastrointestinal (GI) symptoms, as research studies have stated. SIFO is generally defined as greater than 1,000 fungi per ml of small intestinal aspirate that can also occur in the large intestine. This is known as LIFO (large intestinal fungal overgrowth. SIFO and LIFO are commonly used together in clinical settings since it is difficult to ascertain where the overgrowth is. Other research studies have stated that SIFO is usually part of immunodeficiency syndrome with other GI disorders.
Research studies have found that SIFO can often develop in individuals with either a weakened immune system or a healthy immune system. The Candida species are located in the mouth, the skin, and the intestines. At low levels, it shouldn’t cause any problems in the body or the gut system; however, if it is not being checked, the fungal species will begin to grow uncontrollably, causing various infections in and out of the body. Some of the symptoms that are caused by SIFO are similar to SIBO as they can cause:
The gut system needs beneficial bacteria in the intestines to help digest and absorb nutrients into the bloodstream to be transported throughout the entire body. These beneficial bacteria help maintain the body’s growth, metabolism, and immune support, making it function properly. When harmful pathogens enter the gut system and cause an overabundance of harmful bacteria in the intestines, it can cause the development of both SIBO and SIFO. These gastrointestinal disorders can disrupt the gut system and cause dysfunction in the entire body if it is not treated right away. Incorporating gut-healthy therapies can provide relief to not only the gut but also the body.
