Your digestive tract is dwelling to trillions of micro organism, or dwell microorganisms. Collectively, they make up what’s often known as the intestine 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 purple flags, however they’re not all dangerous. Nonetheless, an excessive amount of micro organism — and the improper form — could cause some points, resembling small intestinal bacterial overgrowth (SIBO). That is when there’s extreme micro organism within the small gut.
Although it sounds easy sufficient, SIBO is way from it. Diagnosing and attending to the foundation of SIBO might be tough, 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 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, stated Ayanna Lewis, MDa board-certified gastroenterologist and member of HealthyWomen’s Girls’s Well being Advisory Council. It’s not simply the extreme quantity of micro organism current, but in addition the presence of micro organism that aren’t usually discovered 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 different sorts is predicated on which sort of gasoline is produced by the overgrowth of micro organism in your intestine.
SIBO signs
SIBO impacts the digestive tract, so most of the widespread signs present up within the intestine or stark adjustments in your rest room habits.
Frequent 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 identified with SIBO after experiencing extreme signs. “My signs included excessive bloating, virtually day by day diarrhea, and burping throughout and after meals.”
SIBO can get in the best way of wholesome digestion, which is critical on your physique to make use of the vitamins out of your meals. In consequence, it may result in malnutrition or nutrient deficiencies, particularly vitamin B12 deficiencies.
SIBO may trigger steatorrhea, or fatty stools. An excessive amount of fats in your stools can typically sign that you’ve got this situation.
Threat components for SIBO
Some are extra seemingly than others to develop SIBO, together with these with current gastrointestinal points. For instance, the chances of getting intestinal methanogen overgrowth SIBO are virtually six instances greater in these with inflammatory bowel illness (IBD) in comparison with these with out.
Researchers have additionally recognized some further threat components, together with illnesses related to SIBO:
SIBO is extra widespread in ladies and other people assigned feminine at beginning (AFAB), and the incidence will increase with age.
What causes SIBO?
“There’s often some underlying motive why somebody has developed this extra of micro organism within the intestine,” Lewis stated. “It’s usually as a consequence of some structural or motility subject.”
For instance, SIBO is a attainable complication of stomach 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 aspect of issues, the slowing or stopping of digestion is believed to play a job 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 stomach 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 contraception drugs additionally will increase your threat for creating SIBO, which can partially clarify why the situation is extra widespread in ladies and other people AFAB.
How you can take a look at for SIBO

Pinpointing SIBO as the foundation reason behind your signs often begins with speaking to a healthcare supplier (HCP). “SIBO might be identified clinically primarily based on signs,” Lewis stated.
There are additionally exams out there, together with a breath take a look at. Hydrogen and methane breath markers make up probably the most extensively used take a look at for SIBO. It’s non-invasive and includes consuming a sugar resolution and measuring your breath for hydrogen and methane gases. That is how Joseph’s SIBO was identified, although she needed to proactively ask her HCP to be examined.
Different exams 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 exams, resembling X-rays, computerized tomography (CT) scans or magnetic resonance imaging (MRI), to determine any structural abnormalities.
Whereas there are a number of completely different exams out there, there isn’t a gold customary for diagnosing SIBO.
As if diagnosing SIBO weren’t tough sufficient, the signs are fairly generic and infrequently overlap with different situations. For instance, SIBO signs might be the identical as IBS signs. This will typically make it difficult to get an correct analysis.
SIBO remedy
SIBO is often 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 come back again — one thing Joseph is worried about.
It might even be essential to modify your weight-reduction plan. Micro organism generally feed on carbohydrates, so a weight-reduction plan excessive in fats and low in carbohydrates and fiber could also be useful.
In Joseph’s case, her HCP prescribed antibiotics and really helpful a low-FODMAP weight-reduction plan. “That is supposed to assist forestall the micro organism from regrowing,” Joseph stated, including that she began to really feel higher virtually instantly after adjusting her weight-reduction plan.
What to do if you happen to suppose you may have SIBO
Any time you discover uncommon adjustments in your rest room habits or expertise signs that simply gained’t go away, it’s a good suggestion to let your HCP know what’s happening.
“These signs ought to all the time 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, resembling 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 might be missed or misunderstood. Her largest piece of recommendation for anybody experiencing SIBO signs: “Be your personal advocate.”
