What is SIBO?

SIBO is bacteria overgrowth of the small intestine. The small intestine plays a key role in healthy digestion and contains a small amount of bacteria. The problem is that an overgrowth of bacteria causes many problems, like fat malabsorption. Also, carbohydrates are prohibited from being absorbed. This leads to them rotting in the intestines, which leads to a whole slew of other problems. The undigested carbohydrates cause abdominal pain, bloating, gas, and diarrhea.

There have been different studies conducted in learning more about SIBO and IBS. One such study occurred at the Cedars-Sinai Medical Center in California. The study included 202 people suffering with IBS. Of the entire group of 202 participants, those who tested positive for SIBO were 157! After being treated for their condition by eliminating the excess bacteria in the small intestine, 48% of the 157 sufferers noticed an improvement regarding their IBS symptoms. So, is there a link between SIBO and IBS it still remains to be determined, although it is believed that the two can coexist.

How to Diagnose SIBO

The small intestinal bacterial overgrowth is tested using a lactulose breath hydrogen test. If someone has SIBO, they will produce high levels of either hydrogen gas or methane. The breath test is considered to be the best way to diagnose SIBO.

How to Treat SIBO

Today, most people understand that the use of antibiotics can correct one problem while creating another one. In general, antibiotics affect bacteria. Antibiotics actually kill bacteria, including the good bacteria that’s necessary to keep everything in balance and keep you healthy. So, if taking antibiotics to treat SIBO, ensure you also take a probiotic simultaneously.

That said, the antibiotics can control the overgrowth of bacteria, but it won’t cure it altogether. Instead, once you stop taking antibiotics, the symptoms of SIBO and IBS will likely return.

However, there are alternative therapies, including acupuncture among others, to help ease the symptoms and improve your condition.
