So let’s get straight into it: what is SIBO? SIBO stands for Small Intestinal Bacterial Overgrowth. As the name suggests, it is a medical condition characterized by an excessive population of bacteria in the small intestine. The normal density of bacteria in the small intestine is about 1 thousand per milliliter, whereas in SIBO this can be as high as 1 million, or even 10 million per milliliter. In addition to a dramatically higher number of bacteria, the type of bacteria also change: there is a shift in the population from friendly bacteria that are necessary for gut health, to species that produce toxins and disrupt the intestinal environment.

Because SIBO is a slow-developing, chronic condition that often goes undiagnosed, it is very difficult to give a precise estimate of its frequency in the general population. The figure could be 5% or lower for younger people, and as high as 15% for the elderly. There are numerous risk factors for its development, including Crohn’s disease, celiac disease, diabetes, cirrhosis of the liver and heavy use of antibiotic medications.

Now the symptoms of SIBO are not specific to SIBO, so as I mentioned it can often be difficult to diagnose. People with SIBO might have chronic bloating, abdominal pain and diarrhea. They might also be weak and fatigued. Other symptoms can include weight loss and osteoporosis, as well as a number of nutritional deficiencies. Patients might become deficient in vitamins A, B12, D, E and K as well as iron and other nutrients.

Treatment for SIBO can be dietary, surgical or medical. So your doctor might suggest steps towards a more healthy and balanced diet, or, if the SIBO stems from a problem with the small intestine’s anatomy, he might recommend surgery. But most doctors will simply prescribe antibiotics. These will work to temporarily reduce the bacterial population, but the problem is that the effect will be short-lived. The average length of symptom improvement you will get after a one-week antibiotic course is a little over 3 weeks. This means you would need approximately one course per month to sustain the results.


So now that we have given a brief overview of SIBO, let’s move on to its possible link with hair loss. Now guys I want to get this clear right off the bat: there is no direct scientific evidence linking SIBO to male or female pattern baldness, or any other type of hair loss. So there are no medical studies that have looked at the hair of people with SIBO and found them to have a higher incidence of hair loss than the general population. But this does not necessarily mean there is no link – a very large percentage, probably the majority of SIBO sufferers, will not be diagnosed in their lifetime. So they, along with their treating health care professionals, will not even know they have the disease, let alone blame it for any hair problems they might be experiencing. Due to this under-appreciation of the scale of the SIBO problem, medical researchers might simply not have had the motivation to examine its link to hair loss or other problems.

So with that out of the way, let’s speculate on the two untested, but quite plausible ways in which SIBO can impact your hair. One is through nutrition and the other is through stress.


So your hair follicles need nutrients, just like any other organ in your body. But hair follicles are not like any other organ. They have a high turnover and very active metabolism, meaning they are especially dependent on an adequate supply of proteins, vitamins and minerals. Crucial among these are vitamins C, B12, Zinc, niacin, iron, copper and selenium.
