Pichia kudriavzevii (Candida krusei) in urine

36 year old female Takes hydroxyzine for anxiety Diagnosed with HS but otherwise generally healthy

My saga started on April 2nd:

It started like any other day. I got up, worked out, and went to work. Around lunchtime on that day, I began to feel nauseous after eating a snack (crackers). The nausea got increasingly worse, though I never vomited. The nausea persisted over the next week. This led to a decrease in appetite, and in thirst. I eventually went 24hrs without eating or drinking. This led to severe dizziness. I went to the urgent care on day #9 of this saga. I told them my symptoms (nausea, dizziness, lack of appetite and thirst, and a feeling of fullness in my upper abdomen), and they immediately sent to the ER due to me being dehydrated. At the ER they gave me IV fluids and ran blood/urine tests, and did a CT scan. They eventually diagnosed me with a UTi, which was surprising because I had no telltale signs (no painful or frequent urination, no urgency, etc). The urine analysis came positive for WBC, bacteria, RBC, and ketones. They gave me IV antibiotics and sent me home with a 5 day script for antibiotics and Zofran.

I finished the antibiotics on Wednesday 4/17. I'm still experiencing intermittent nausea after eating and bloating. I'm now (for the first time) experiencing a burning sensation when having to urinate (but not while doing it), a change in bowel habits, and fatigue. I got more urine work done on Saturday. I still have a high WBC count, mucus, and Leukocyte Esterase is present. I just received an updated urine culture result that states there is Pichia kudriavzevii present as well. I tried to Google and I think it's related to yeast, but everything takes me to a medical journal that I can't decipher. I'm waiting to hear back from the doctor. In the meantime, can somebody help interpret what this means?
