Sugar in urine does not always mean a person has diabetes, according to the National Organization for Rare Disorders, or NORD. Fanconi’s syndrome is a renal disorder that may occur in association with kidney transplantation and certain genetic disorders. The condition impairs the functioning of kidneys, and its symptoms include an abnormal level of glucose in urine and increased acidity of blood.
Some people suffer from rare disorders such as renal glycosuria, a condition that causes the kidneys’ filtering units to malfunction and release sugar into urine in spite of low glucose level in the body, according to NORD. The condition may raise the level of glucose in urine in case blood sugar levels are abnormally high, says Healthline. In most patients, glycosuria does not exhibit other symptoms, but in rare cases, it causes excessive urination, thirst and loss of glucose, reports NORD.
Rarely, sugar in urine characterizes pregnancy, since pregnant women are likely to have higher levels of glucose in their urine than other people, reports Healthline. High blood pressure may cause chronic kidney disease, which affects the kidney’s filtering ability, leading to loss of blood sugar through urine, says the National Kidney Foundation. Certain medications tend to affect the level of glucose in a patient’s blood and urine. Urine glucose levels may also elevate due to stress or binge eating.
