Your digestive tract is dwelling to trillions of micro organism, or dwell microorganisms. Collectively, they make up what’s often known as the gut microbiome. This ecosystem of micro organism primarily resides in your massive gut (aka the colon), however a small portion dwells in your abdomen and small gut.
The phrase “micro organism” can increase some crimson flags, however they’re not all dangerous. Nonetheless, an excessive amount of micro organism — and the mistaken variety — could cause some points, comparable to small intestinal bacterial overgrowth (SIBO). That is when there’s extreme micro organism within the small gut.
Although it sounds easy sufficient, SIBO is much from it. Diagnosing and attending to the basis of SIBO will be difficult, and it’s not clear how many individuals have it.
Right here’s what’s at the moment recognized about SIBO, so you possibly can higher perceive it your self.
What’s SIBO?
SIBO happens when an excessive amount of micro organism — particularly colonic micro organism from the big gut — enters the small gut.
Some micro organism within the small gut is regular, however SIBO is a buildup of micro organism within the intestine, stated Ayanna Lewis, M.D., a board-certified gastroenterologist and member of HealthyWomen’s Women’s Health Advisory Council. It’s not simply the extreme quantity of micro organism current, but additionally the presence of micro organism that aren’t normally found there. There are 4 several types of SIBO, together with hydrogen-dominant, intestinal methanogen overgrowth, combined (additionally known as methane-hydrogen dominant), and hydrogen sulfide SIBO. The classification of the differing types relies on which kind of gasoline is produced by the overgrowth of micro organism in your intestine.
SIBO signs
SIBO impacts the digestive tract, so lots of the widespread signs present up within the intestine or stark adjustments in your toilet habits.
Widespread signs of SIBO embrace:
- Stomach distension or bloating
- Stomach ache
- Diarrhea
- Discomfort
- Gasoline
- Indigestion
- Nausea
- Sense of fullness
- Unintentional weight reduction
“I felt like I had a brick in my abdomen,” stated Jill Joseph, a girl in her 50s who was recognized with SIBO after experiencing extreme signs. “My signs included excessive bloating, nearly each day diarrhea, and burping throughout and after meals.”
SIBO can get in the way in which of wholesome digestion, which is important in your physique to make use of the vitamins out of your meals. Consequently, it may result in malnutrition or nutrient deficiencies, particularly vitamin B12 deficiencies.
SIBO may also trigger steatorrhea, or fatty stools. An excessive amount of fats in your stools can generally sign that you’ve got this situation.
Danger elements for SIBO
Some are extra doubtless than others to develop SIBO, together with these with current gastrointestinal points. For instance, the percentages of getting intestinal methanogen overgrowth SIBO are almost six times greater in these with inflammatory bowel disease (IBD) in comparison with these with out.
Researchers have additionally recognized some further danger elements, together with ailments related to SIBO:
SIBO is extra widespread in ladies and folks assigned feminine at beginning (AFAB), and the incidence will increase with age.
What causes SIBO?
“There’s normally some underlying cause why somebody has developed this extra of micro organism within the intestine,” Lewis stated. “It’s typically on account of some structural or motility subject.”
For instance, SIBO is a potential complication of belly surgical procedure. “It may be quite common in cesarean supply (C-section) or gallbladder surgical procedures,” Lewis stated. Stomach surgical procedures could cause structural adjustments, which may alter digestion and permit bacterial overgrowth within the small gut.
As for the motility facet of issues, the slowing or stopping of digestion is believed to play a task in SIBO. Because of this it’s generally associated to blind loop syndrome — when meals bypasses part of the gut throughout digestion, generally as a complication of belly surgical procedure. This additionally explains why SIBO can occur in these with constipation — slower digestion creates extra alternatives for micro organism to linger and develop within the small gut.
Utilizing mixture oral birth control pills additionally will increase your danger for growing SIBO, which can partially clarify why the situation is extra widespread in ladies and folks AFAB.

Pinpointing SIBO as the basis reason behind your signs normally begins with speaking to a healthcare supplier (HCP). “SIBO will be recognized clinically primarily based on signs,” Lewis stated.
There are additionally checks out there, together with a breath take a look at. Hydrogen and methane breath markers make up the most widely used test for SIBO. It’s non-invasive and includes ingesting a sugar resolution and measuring your breath for hydrogen and methane gases. That is how Joseph’s SIBO was recognized, although she needed to proactively ask her HCP to be examined.
Other tests for SIBO might embrace:
- A small gut aspirate and fluid tradition — an endoscope is inserted by means of the mouth to the small gut to gather a fluid pattern for lab evaluation.
- Blood testing to search for any nutrient deficiencies.
- Fecal fats testing — a stool pattern is examined for fats malabsorption.
- Imaging checks, comparable to X-rays, computerized tomography (CT) scans or magnetic resonance imaging (MRI), to determine any structural abnormalities.
Whereas there are a number of completely different checks out there, there isn’t a gold normal for diagnosing SIBO.
As if diagnosing SIBO weren’t difficult sufficient, the signs are fairly generic and sometimes overlap with different circumstances. For instance, SIBO signs will be the identical as IBS signs. This could generally make it difficult to get an correct analysis.
SIBO therapy
SIBO is normally handled with oral antibiotics. Your HCP might prescribe 10–14 days of antibiotics to cut back the micro organism within the small gut. In some instances, you’ll have to cycle by means of a number of rounds of antibiotics to handle recurring signs since SIBO is thought to return again — one thing Joseph is worried about.
It might even be essential to adjust your diet. Micro organism generally feed on carbohydrates, so a weight loss plan excessive in fats and low in carbohydrates and fiber could also be useful.
In Joseph’s case, her HCP prescribed antibiotics and beneficial a low-FODMAP diet. “That is supposed to assist stop the micro organism from regrowing,” Joseph stated, including that she began to really feel higher nearly instantly after adjusting her weight loss plan.
What to do for those who assume you’ve gotten SIBO
Any time you discover uncommon adjustments in your toilet habits or expertise signs that simply received’t go away, it’s a good suggestion to let your HCP know what’s happening.
“These signs ought to at all times immediate you to go see a gastroenterologist and get further testing,” Lewis stated. “The aim of that is to verify there aren’t different underlying points, comparable to a bowel obstruction, that shouldn’t be ignored.”
Joseph’s private journey took many turns earlier than she discovered a analysis, additional demonstrating how SIBO will be missed or misunderstood. Her largest piece of recommendation for anybody experiencing SIBO signs: “Be your personal advocate.”
