One possibility is prediabetes or early diabetes with slow uptake of glucose. Thus your tissues are underfed while glucose circulates in your blood. Testing is important for this.

First, the alkaline pH most commonly arises from an active bacterial urinary infection. The bacteria change the urine pH to alkaline. In a rare circumstance, a person can show an alkaline urine from extreme consumption of alkaline foods such as greens. This is very rare. Your urine is infected. Bactrim is prudent. Urobilinogen is ordinary in small amounts. Urobilinogen comes from ordinary metabolism of bilirubin from the liver and is excreted as a waste. Normally, most uribilunogen comes through the liver into bile ducts and then is dumped into the intestine and is excreted with bowel movements. An increase in urine urobilinogen is of concern: liver dysfunction can disturb normal passage of urobilinogen through bile ducts, such as bile duct blockage or an inflamed liver. Or, if a hemolytic anemia is active, then more bilirubin is made from the released hemoglobin.
