Small intestinal bacterial overgrowth (SIBO) is an excess of bacteria found in the small intestine. Proper digestion and absorption of nutrients take place in the small intestine. When the environment in the small intestine is disturbed with an overgrowth of bacteria, usually due to the migration of bacteria from the large intestine, our digestive process is compromised and can lead to a host of health issues you may be experiencing right now. Interestingly, studies have indicated that potentially up to 80% of patients with IBS may, in fact, have SIBO.
Low or no stomach acid
Pancreatic enzyme and/or bile insufficiency
GI tract dysfunction (ileocecal valve)
SIBO can lead to many diseases, disorders and health ailments such as:
Chronic Fatigue Syndrome
Irritable Bowel Syndrome
Type 2 diabetes
High Blood Pressure
Restless Leg Syndrome
Weight loss/Weight gain
The SIBO breath test involves a 24-48 hour prep diet. This means 24-48 hours prior to your test.
Some practitioners may suggest a longer prep depending on how fast your intestinal tract moves along i.e. constipation. However, that is something you would have to discuss with your practitioner OR you can email SIBO CLINIC CANADA at firstname.lastname@example.org for help.
During this prep, stop taking all non-essential medications, supplements, and pro-biotics. This includes over the counter pain medications, allergy medications, and antacids. If you don’t know what medication is considered essential, consult your prescribing physician. The goal is to starve the bacteria for a day in order to produce the best results when doing the test. Bacteria fuel on plant products and sugars, so the only foods that you can have on the prep diet are listed here – if it is not on this list DO NOT eat it:
Any meat/poultry/fish/seafood that is not cured or brinedPlain, steamed white riceEggsClear meat broth (made only from the meat, no bone/cartilage or vegetables)Fats/oils (coconut/olive/vegetable oils, butter, or lard)Salt and Pepper (no other herbs/spices)Weak black coffee and/or weak black tea (plain, no sweeteners or cream, NO green or herbal teas)Plain water (no mineral water or water with additives)
No. Any changes to the diet can affect the results of the test. The manufacturer of the SIBO test created the prep diet based on their research and testing. Only the things on the prep diet are allowed to get the cleanest results for the SIBO test.
No. If you do not eat grains, for example, do not consume the rice. If you do not eat eggs, then do not start just for this diet. Eat things on this list, but only of what you would normally eat.
Many practitioners may will modify your diet to what they feel is the best test for you. We at SIBO CLINIC CANADA only go by what the manufacturer of the SIBO test (Qiuntron) has worked with to create the guidelines for the test. If your practitioner has a specific modification (such as hard cheeses) then you must discuss it with them, as we cannot give advice about foods outside of the manufacturer’s guidelines. However, although cheese is a form of dairy, and dairy is not on the list of foods to consume because of the latose-containing sugar, hard aged cheeses have minute tracres of lactose, and the more aged the cheese, the less lactose it contains. If you do find the prep diet far too constrictive, and feel the need to have cheese, please proceed with caution and make sure the cheese is non-processed aged cheese.
The only grain acceptable on the prep diet is plain, white Basmati or Jasmine rice because they have the lowest glycemic index of all rice. Other rice/grains have a higher level of fiber and macromolecules that SIBO bacteria like to eat. Any substitutions can give inaccurate test results. If you normally do not eat rice, do not eat any during the prep diet.
The SIBO prep diet specifically cuts out plant products and sugars in order to starve the bacteria for a day prior to taking the test, which will give you the most accurate results. If you do not adhere to the diet, the bacteria may not react during the test, leading to possible false negative results. If you do not normally consume poultry/meat/eggs, please consult with nutritional expert to determine your options.
Regular bone broth is often cooked with cartilaginous bones or meat. When cooked, polysaccharides (specifically glucosaminoglycans or GAGs) from the cartilage leech into the bone broth and can feed a bacterial overgrowth and therefore be problematic for people with SIBO.
It is important that if you consume meat broth for the prep diet, it must be made from ONLY the meat. There cannot be any bone or cartilage included, and it cannot have any vegetables or herbs (aside from salt and pepper) in it. Most store bought broths have ingredients that are not appropriate for this prep diet, so homemade broth is the best decision.
Any meat ingested must be made without any added sugars/brines/cures/etc. to avoid contaminating the prep diet. Avoid meats like deli-meat, lox, and pre-prepared meats that have any other herbs and spices besides salt and pepper. Meats like sausage usually have other herbs or sugars in them and should be avoided during the prep diet.
The sashimi fish is fine on the prep diet, when eaten alone and without sauce. The rice in Nigiri is usually made with sugar-based binders to make it stick together better, and thus should be avoided on the prep diet. The only exception is home-made Nigiri with steamed white rice and no sauces. Sushi rolls are very much to be avoided.
If you are a smoker, of tobacco or cannabis, there is no recommendation to stop use during the prep diet. However, do not smoke anything for at least one hour prior to taking the breath test, or during the time of the test (4 hours total). If you ingest cannabis in edible form, it must be avoided during the prep diet. Smokeless tobacco (chew) should be avoided during the prep diet and prior to the test as well. Avoid all alcohol during the prep diet.
