Gordon had a fungal overgrowth in his small intestine due to the numerous rounds of antibiotics he was taking for recurring staph infections; he'd get staph, take antibiotics, it would go away, then he'd get staph again, take antibiotics, it would go away. This cycle went on for some time, and because he was taking so many antibiotics for such a long period of time, it completely wiped out all of the good bacteria in his gut, thus allowing for the fungal overgrowth to get worse and worse, subsequently causing Gordon to suffer very unpleasant symptoms. It's crazy to think that none of that would've happened had he ingested probiotics of some sort to replenish the good bacteria and to restore his healthy gut function after he finished each round of antibiotics. Instead he suffered with a worsening by the day case of nasty bacterial fungal overgrowth in his small intestine, causing him to suffer from extreme, debilitating nausea and vomiting, painful stomach cramps, and his digestive system not working correctly. Iirc he suffered through this condition for several months at least, could've been longer, could've been shorter, though I'm pretty sure it was longer. He went to a few different doctors who unfortunately misdiagnosed his condition as Gastroparesis and told him not to worry, all the while, the bacterial fungus is growing and spreading, making his systems worse by the day, until finally after several long, long months of trying to find the answer to what had been plaguing him for so long, a friend recommended a specific doctor who turned out to be exactly what Gordon needed. He correctly diagnosed Gordon and began treating the bacterial fungal overgrowth. The end
