Is There a Microbiome in a Small Intestinal Gastrointestinal Tract?

My fructose malabsorption seems way more severe than what's talked about in the literature. So my experience is I can probably tolerate fructose if I have a 10 or 20 glucose to fructose ratio. But just glucose has maybe 5% or 10% of the capacity to stimulate the symptom as fructose does. Some people are very sensitive to fructose, even tiny amounts. And some people tend to tolerate larger amounts. Within your disease state, it can get worse. It can get better.
