Digestion isn’t at all times glamorous to speak about, however it can be crucial. And when issues aren’t operating easily, it may very well be your intestine’s method of getting your consideration.
Your digestive tract is dwelling to trillions of micro organism, or stay microorganisms. Collectively, they make up what’s referred to as the gut microbiome. This ecosystem of micro organism primarily resides in your giant 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. Nevertheless, an excessive amount of micro organism — and the fallacious 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 foundation of SIBO may be tough, and it’s not clear how many individuals have it.
Right here’s what’s at the moment identified 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 massive 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, mentioned 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 various kinds of SIBO, together with hydrogen-dominant, intestinal methanogen overgrowth, combined (additionally referred to as methane-hydrogen dominant), and hydrogen sulfide SIBO. The classification of the different sorts relies on which sort of gasoline is produced by the overgrowth of micro organism in your intestine.
SIBO signs
SIBO impacts the digestive tract, so lots of the frequent signs present up within the intestine or stark adjustments in your lavatory habits.
Widespread signs of SIBO embrace:
- Belly distension or bloating
- Belly ache
- Diarrhea
- Discomfort
- Gasoline
- Indigestion
- Nausea
- Sense of fullness
- Unintentional weight reduction
“I felt like I had a brick in my abdomen,” mentioned Jill Joseph, a girl in her 50s who was recognized with SIBO after experiencing extreme signs. “My signs included excessive bloating, nearly day by day diarrhea, and burping throughout and after meals.”
SIBO can get in the best way of wholesome digestion, which is critical to your physique to make use of the vitamins out of your meals. Because of this, it might result in malnutrition or nutrient deficiencies, particularly vitamin B12 deficiencies.
SIBO can even trigger steatorrhea, or fatty stools. An excessive amount of fats in your stools can typically sign that you’ve 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 chances of getting intestinal methanogen overgrowth SIBO are almost six times increased in these with inflammatory bowel disease (IBD) in comparison with these with out.
Researchers have additionally recognized some further danger elements, together with illnesses related to SIBO:
SIBO is extra frequent in girls and folks assigned feminine at delivery (AFAB), and the incidence will increase with age.
What causes SIBO?
“There’s often some underlying cause why somebody has developed this extra of micro organism within the intestine,” Lewis mentioned. “It’s usually on account of some structural or motility difficulty.”
For instance, SIBO is a attainable complication of belly surgical procedure. “It may be quite common in cesarean supply (C-section) or gallbladder surgical procedures,” Lewis mentioned. Belly surgical procedures could cause structural adjustments, which might 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. For this reason it’s typically associated to blind loop syndrome — when meals bypasses part of the gut throughout digestion, typically 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 frequent in girls and folks AFAB.

Pinpointing SIBO as the foundation reason for your signs often begins with speaking to a healthcare supplier (HCP). “SIBO may be recognized clinically primarily based on signs,” Lewis mentioned.
There are additionally exams obtainable, 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 could embrace:
- A small gut aspirate and fluid tradition — an endoscope is inserted by way 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 exams, comparable to X-rays, computerized tomography (CT) scans or magnetic resonance imaging (MRI), to establish any structural abnormalities.
Whereas there are a number of totally different exams obtainable, there isn’t a gold customary for diagnosing SIBO.
As if diagnosing SIBO weren’t tough sufficient, the signs are fairly generic and sometimes overlap with different circumstances. For instance, SIBO signs may be the identical as IBS signs. This could typically make it difficult to get an correct prognosis.
SIBO therapy
SIBO is often handled with oral antibiotics. Your HCP could prescribe 10–14 days of antibiotics to cut back the micro organism within the small gut. In some instances, you might have to cycle by way of a number of rounds of antibiotics to deal with recurring signs since SIBO is thought to return again — one thing Joseph is anxious about.
It might even be essential to adjust your diet. Micro organism generally feed on carbohydrates, so a food regimen 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 forestall the micro organism from regrowing,” Joseph mentioned, including that she began to really feel higher nearly instantly after adjusting her food regimen.
What to do should you assume you’ve gotten SIBO
Any time you discover uncommon adjustments in your lavatory habits or expertise signs that simply gained’t go away, it’s a good suggestion to let your HCP know what’s occurring.
“These signs ought to at all times immediate you to go see a gastroenterologist and get further testing,” Lewis mentioned. “The aim of that is to ensure 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 prognosis, additional demonstrating how SIBO may be missed or misunderstood. Her greatest piece of recommendation for anybody experiencing SIBO signs: “Be your individual advocate.”
