From Liverpool, UK:

My younger sister is 28 and has been displaying diabetic symptoms for about 6 months: increased thirst, excessive urination, pins and needles in her hands and feet, accompanied by high blood sugars, of at least 10 mmol/l (180 mg/dl). Her hospital blood tests were normal, along with her GTT. However, she is still having high blood glucose levels, is losing weight rapidly, and seems generally unwell and lacking in energy. Is it still possible she is diabetic even after her hospital results, and if so, why are her blood glucoses still high? Her meter has been tested and it is functioning correctly. Please help, her family are very concerned. Any advice would be appreciated.


A capillary blood sugar meter is not sufficient for diagnosing diabetes. Blood sugars of 10mmol/L (random) are not diagnostic of diabetes. These things said, a GTT is a notoriously fickle test and you don't say how long ago it was performed. If your sister also has glucose in her urine then she has, at very least, glucose intolerance. It is always easy to say that the doctors made a mistake but your sister should ask for an explanation for her symptoms, a urine glucose test and a Haemoglobin A1c as a minimum.
