Digestion isn’t at all times glamorous to speak about, however it will be significant. And when issues aren’t operating easily, it may very well be your intestine’s means of getting your consideration.
Your digestive tract is house to trillions of micro organism, or reside microorganisms. Collectively, they make up what’s often called 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 pink flags, however they’re not all dangerous. Nevertheless, an excessive amount of micro organism — and the improper sort — could cause some points, equivalent 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 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 presently 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, stated Ayanna Lewis, M.D., a board-certified gastroenterologist and member of HealthyWomen’s Ladies’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 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 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 most of the widespread signs present up within the intestine or stark modifications in your rest room habits.
Frequent signs of SIBO embody:
- 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 lady 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 best way of wholesome digestion, which is important in your physique to make use of the vitamins out of your meals. Because of this, 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 this situation.
Threat elements for SIBO
Some are extra probably than others to develop SIBO, together with these with current gastrointestinal points. For instance, the percentages of getting intestinal methanogen overgrowth SIBO are nearly six instances greater in these with inflammatory bowel illness (IBD) in comparison with these with out.
Researchers have additionally recognized some extra threat elements, together with ailments 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 typically as a consequence of some structural or motility problem.”
For instance, SIBO is a doable 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 modifications, 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. This is the 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 contraception tablets additionally will increase your threat for growing SIBO, which can partially clarify why the situation is extra widespread in ladies and other people AFAB.
How one can check for SIBO

Pinpointing SIBO as the foundation reason for your signs often begins with speaking to a healthcare supplier (HCP). “SIBO might be recognized clinically primarily based on signs,” Lewis stated.
There are additionally exams out there, together with a breath check. Hydrogen and methane breath markers make up essentially the most extensively used check for SIBO. It’s non-invasive and entails consuming 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.
Different exams for SIBO could embody:
- A small gut aspirate and fluid tradition — an endoscope is inserted by 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, equivalent 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 out there, there isn’t a gold commonplace 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 could typically make it difficult to get an correct analysis.
SIBO remedy
SIBO is often handled with oral antibiotics. Your HCP could prescribe 10–14 days of antibiotics to scale back the micro organism within the small gut. In some instances, you might have to cycle by a number of rounds of antibiotics to deal with recurring signs since SIBO is thought to return again — one thing Joseph is worried about.
It could even be essential to regulate your food regimen. Micro organism generally feed on carbohydrates, so a food regimen excessive in fats and low in carbohydrates and fiber could also be helpful.
In Joseph’s case, her HCP prescribed antibiotics and really helpful a low-FODMAP food regimen. “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 food regimen.
What to do for those who assume you will have SIBO
Any time you discover uncommon modifications 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 at all times immediate you to go see a gastroenterologist and get extra testing,” Lewis stated. “The aim of that is to ensure there aren’t different underlying points, equivalent 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 might be missed or misunderstood. Her greatest piece of recommendation for anybody experiencing SIBO signs: “Be your personal advocate.”
