If you think you have intestinal Candida yeast overgrowth and are having a hard time getting it under control you may have SIBO (small intestine bacterial overgrowth). The symptoms of SIBO aka SBBO (small bowel bacterial overgrowth ) are very similar to those of Candida so it’s easy to confuse the two conditions. It is possible and not uncommon to have both conditions.
What is SIBO
Small intestine bacterial overgrowth is, as the name suggests, an overgrowth of bacteria in the small intestine. It is an overgrowth of bacteria that should not be present in large quantities in the small intestine.
Although the entire digestive system is populated with bacteria the small intestine does not contain anywhere near the number of bacteria that is found in the large intestine (colon).
The type of bacteria that are normally found in the small intestine are different from the bacteria that reside in the large intestine but in SIBO a large number of bacteria from the colon and lower part of the small intestine have found their way into the upper part of the small intestine.
Once the bacteria trans-locate to the small intestine they cause a lot of symptoms as they ferment the food passing through. The main purpose of the small intestine is to digest and absorb the nutrients from the food into the body. What is left passes through to the large intestine where water and some minerals are absorbed into the body before it is excreted.
Sibo has been linked to IBS, chronic fatigue syndrome, fibromyalgia, food intolerance, leaky gut, Lyme Disease and environmental illness. A high percentage of IBS sufferers have now been found to have SIBO as the cause of most of their symptoms.
Symptoms of SIBO
SIBO can cause the following symptoms:
Diarrhea or more frequent bowel movements
Mucous in stools
When the condition has been present for some time it can lead to:
Leaky gut ( increased permeability)
General body aches and pains
As you can see these are the very same symptoms that might make you think you have Candida overgrowth or IBS.
The bacteria ferment the food in the small intestine which produces gas and toxic substances. The gas causes abdominal bloating and pain. The toxins irritate and damage the intestinal lining causing inflammation, pain, diarrhea and leaky gut.
What is the cause of SIBO?
If the normal muscular wave like contractions of the small intestine are interrupted for any reason then bacteria from the colon and lower end of the small intestine can migrate to the upper parts of the small intestine. The waves sometimes called cleansing waves or peristalsis should be continuous and help to push the food along the length of the small intestine into the colon.
Many things can interfere with peristalsis such as:
Low stomach acid
Malfunction of ileo-cecal valve ( valve between small & large intestine)
Proton pump inhibiting drugs
Muscular and neurological diseases
How do you know if you have SIBO?
There is no perfect test for SIBO but the favorite is the 3 hour lactulose hydrogen breath test. It is possible though to have bacterial overgrowth that cannot be detected by this method. Humans can’t digest or absorb lactulose. Most bacteria can and this produces hydrogen and methane which can be measured in the breath.
Treatment for SIBO
Mainstream doctors usually treat it with antibiotics but this does not provide a lasting cure and the condition often recurs because the underlying cause has not been addressed. Antibiotics can lead to an overgrowth of Candida yeast.
What we eat creates the environment in our digestive system. The beneficial bacteria survive on high fiber diets but high fiber diets can be a problem for some people with SIBO. Meals that are high in meat and fat and low in fiber tend to encourage the putrefactive bacteria.
A strict diet can help to starve the bacteria. The cleansing waves of the small intestine only occur when you are not eating so frequent meals or snacking should be avoided. Bowel cleansing can help sweep the bacteria out of the small intestine and herbs can help reduce the bacterial overgrowth.
A supplement of hydrochloric acid (HCL) is often needed with meals to help acidify the stomach and to keep the bacteria down. .
The diet should consist of easily digested food. The best foods are organic eggs, fresh meats (not preserved), low mercury fish, fresh, non starchy vegetables and fruit, nuts and seeds, their cold pressed oils and ghee.
Lightly cooked fresh, non starchy vegetables are considered better than raw food initially to calm down the gut. Limit fruit to 1 – 2 servings a day daily and avoid all dried fruit.
Fruit should be eaten on its own or as a snack between meals and not be combined with or eaten after meals as it can encourage fermentation if it sits in the stomach for any length of time.
One serving of fruit can be combined with green leaves to make a very digestible and nutritious Green Smoothie. Vegetables can be made into nutritious soups. Meat can be cooked slowly as a casserole with vegetables to make it easier to digest. Bone broths can help to supply the nutrients that have become deficient.
Sugar and sweeteners of all kinds should be avoided including dairy products as they contain the hard to digest milk sugar, lactose. Avoid grains & cereals.
It’s best to avoid all processed foods (any packet or tinned foods). The original foods have been stripped of most nutrients and contain additives and preservatives that can damage the gut flora.
Use plenty or garlic and fresh ginger both cooked and raw in your food preparation. Ginger contains substances that improves motility of the gut, may improve digestive enzymes, and has anti-bacterial and antioxidant properties. Garlic is anti-spasmodic and can help with pain, It is also anti-fungal an anti-bacterial and seems to promote the growth of the friendly gut flora.
Many people have found that the SCD (specific carbohydrate diet) or the Gaps Diet (Gut and Psychology Diet) has helped them but it can take several years unless you use some herbs as well.
Natural anti-bacterial herbs for SIBO
There are a number of outstanding herbs that can be used to help combat SIBO such as grapefruit seed extract, chaparral, oregano, olive leaf extract, goldenseal, oregon grape, barberry, and goldthread sometimes called Chinese goldenseal ( coptis chinensis)
So if you you have been troubled with Candida that seems to defy all treatment it pays to consider SIBO and get tested for it.
