Small Intestine Bacterial Overgrowth (SIBO) in Lyme Disease

SIBO in Lyme Disease

Small intestinal bacterial overgrowth (SIBO) in Lyme disease may make improvement difficult. In this condition, large intestine bacteria move into the small intestines. There, they cause

• bloating and gas,
• nausea,
• constipation or diarrhea,
• inflammation cytokines,
• vitamin deficiencies like low Vitamin B12, and
• several food intolerances.

Keep in mind, any condition that triggers more cytokines can make it look like the underlying Lyme disease is worse than what it is. As I explain in Control Cytokines: A Guide to Fix Lyme Symptoms & The Immune System (Chapter 31), most Lyme disease symptoms are caused by excess cytokines. So, if SIBO triggers more cytokines, it will worsen a person’s Lyme disease symptoms.

In Lyme disease, SIBO develops due to disruption of good stomach and intestinal function caused by the Lyme and the tick-borne coinfections, side effects of medicines, and disruption of good bacteria balance from using herbal and prescription antibiotics.

Successful resolution of symptoms involves

• restoring proper functioning of the intestines,
• eating a healthy plant-based diet,
• removing the large intestine bacteria from the small intestines, and
• restoring good balance of bacteria and functioning of the intestines.

Make Sure It Is Not Yeast

SIBO and yeast overgrowth of the large intestines can look a lot alike. Both lead to an increase in inflammation cytokines—both often produce intestinal gassiness and bloating. Before I test for SIBO, I often address yeast overgrowth first.

Marty Ross MD Discusses SIBO Tests & Antibiotics

Test for SIBO

There are two ways to test for SIBO. One is to have a culture of your small intestines. If too many bacteria grow, then a person has SIBO. An intestine specialist has to perform this test using a scope which is passed through the mouth into the intestines. Because of cost and comfort issues, this test is often not done.

The easiest way to test is called a SIBO Breath Test. It is not as exact as the intestinal test above, however. In the breath test, a person swallows lactulose or glucose sugar water. Then, over a two- or three-hour time period you collect breath samples. If a person’s breath contains high amounts of hydrogen or methane, the test is positive. This test can be performed at home. In my practice, I use the test kit from Genova Diagnostics.

The downside to the SIBO Breath Test is it only finds up to 70 percent of people that have the illness. So, you could have a negative test, but still have the condition. For this reason, the small intestine culture is much more accurate.

Diet for SIBO

The First Eight Weeks

During a support regimen, people with SIBO often get symptom relief, and start to restore normal gut function by eating a FODMAP diet over an eight-week period of time. FODMAP stands for

• Fermentable
• Oligosaccharides (like fructans and galacto-oligosaccharides (GOS))
• Disaccharides (like lactose from cow’s milk)
• Monosaccharides (like excess fructose from fruit)
• And
• Polyols (like sorbitol, mannitol, maltitol, xylitol and isomalt).

These simple sugars are fermented by the small intestine bacteria producing the gas associated with this illness. Stopping these foods can help starve these bacteria and decrease symptoms. For more information, see the FODMAP food plan overview from the Institute for Functional Medicine (ifm.org) or work with a nutritionist. You can also find various books on the internet.

After SIBO is Under Control

The FODMAP diet is not meant to be a permanent diet and is hard to do for a long time. After SIBO is under control, then shift to a diet that is rich in plant-based foods. Such diets support healthy gut function and a balanced gut microbiome. These diets are also anti-inflammatory. I suggest either a “Mediterranean Style” diet or a paleo diet that emphasizes plants. See The Best Brain, Inflammation, Pain, Energy, and Detox Diet Ever.

Herbal and Prescription Antibiotics

Hydrogen Producing SIBO

Hydrogen-producing SIBO without methane is fairly easy to improve. For some just making the dietary changes above could be enough. But most will require antibiotics. In my practice I find the most success using the prescription antibiotic Rifaximin for 2-4 weeks. It stays in the intestines and is not absorbed into the blood. Studies show this works up to 70 percent of the time.

If this fails, or as an alternative, based on my clinical experience I suggest the an herbal antibiotic compound that includes various herbal medicines like oregano that may kill SIBO and restore balance.

Methane +/- Hydrogen Producing SIBO

Methane-producing SIBO is much harder to deal with. In my experience, it takes one to two months of a combination of Rifaximin and neomycin while eating low FODMAP foods. Studies show these two antibiotics reduce symptoms and eradicate methane producing SIBO up to 80% of the time. Initially, I prescribe one month of these antibiotics. If one month does not work, then I may try an additional month.

If the combination of Rifaximin and neomycin fails, or as an alternative, based on my clinical experience I suggest the an herbal antibiotic compound that includes various herbal medicines like oregano that may kill SIBO and restore balance.

Antibiotic Doses

• Rifaximin 550 mg 1 pill 2 times a day.
• Neomycin 500 mg 1 pill 2 times a day.
• Microbe & Biofilm Support Blend Tincture. Start at 2 drops on the tongue 3 times a day and increase every other day by 1 drop per dose until you reach 10 drops 3 times a day. If you develop a Herxheimer die-off reaction, do not increase until it passes. Take without food, meaning at least 30 minutes before food and more than 2 hours after food.
  • • (Supportive nutritional ingredients in a blend may include: Bilberry fruit extract, Grape seed extract, Shiitake mushroom extract, Golden Sea root, Noni fruit extract, Garlic bulb, White Willow bark, Milk Thistle seed, Raspberry fruit, Echinacea Purpurea plant extract, Echinacea Angustifolia root, Black Walnut hull, Black Walnut Walnut leaf, Lavender oil, Oregano oil, Galbanum oil, Tea Tree oil, Fumitory aerial parts extract, Gentian Lutea root.)
• Microbe & Biofilm Support Blend Capsules. Start at 1 capsule 2 times a day and after 2 days increase to 1 capsule 3 times a day. Every 2 days add 1 capsule until you take 2 capsules 3 times a day. If you develop a Herxheimer die-off reaction, do not increase until it passes. Take without food, meaning at least 30 minutes before food and more than 2 hours after food.
  • • • (Supportive nutritional ingredients in a blend may include: Bilberry fruit extract, Grape seed extract, Shiitake mushroom extract, Golden Sea root, Noni fruit extract, Garlic bulb, White Willow bark, Milk Thistle seed, Raspberry fruit, Echinacea Purpurea plant extract, Echinacea Angustifolia root, Black Walnut hull, Black Walnut Walnut leaf, Lavender oil, Oregano oil, Galbanum oil, Tea Tree oil, Fumitory aerial parts extract, Gentian Lutea root.)

Probiotics

Restoring healthy gut function requires probiotics. However, for some with SIBO, probiotics can increase the bloating and cramping until the bacteria are under control.

While a person is on SIBO herbal or prescription antibiotics, I recommend taking a soil-based spore-forming probiotic which does not contain any prebiotic fiber. A prebiotic is a substance that supports the bacteria in a probiotic supplement. The prebiotics found in many probiotics can cause more gas and bloating. Corebiotic Sensitive by Researched Nutritionals is a spore-forming probiotic with no prebiotic fiber. Generally, most of my patients with SIBO can tolerate this. I suggest giving it a try, but if it makes things worse, then stop.

Once a support regimen is complete for active SIBO, probiotics should be used to keep it from coming back. These can include ones with prebiotics and can include both spore-forming ones and human bacteria-based ones. For more information about these different types of probiotics, read Your Guide to a Healthy Intestinal Microbiome—Even on Antibiotics

Here are the probiotics I recommend to my patients.

• Spore Forming Probiotic with Prebiotic Fiber (Bacillus) 2-4 pills 1 time a day. If a product causes gassiness, consider using Spore Forming Probiotic without Prebiotic Fiber (Bacillus), which does not include prebiotic fiber.
