1. Urinating more than usual
Typically, the average person urinates between four and seven times per day, but those suffering with diabetes urinate more frequently because the kidneys produce more urine in an attempt to eliminate excess sugar. Usually, the kidneys re-absorb the sugar and pump it into the bloodstream, but because there’s too much sugar, they create a surplus of urine to get rid of it. This puts a lot of stress on the kidneys and, if left untreated, could cause kidney failure down the line. On a related note, a diabetic may also be thirstier due to constant urination.
