Renal glycosuria treated as diabetes mellitus: case report.
A case of renal glycosuria is reported. A 55 year old female was diagnosed and treated in an upcountry hospital for diabetes mellitus. She developed symptoms of hypoglycaemia while on an oral hypoglycaemic agent, leading to her admission in Mulago Hospital. Persistent glycosuria was noted despite treatment and normal serum glucose. Oral glucose tolerance test and timed urine glucose showed a normal curve but high urine sugar. A diagnosis of renal glycosuria was made, oral hypoglycaemic therapy was stopped, patient improved and was discharged. Though renal glycosuria is a benign condition, mistaken diagnosis for diabetes mellitus puts patients at risk of hypoglycaemia due to treatment. Diagnosis of the condition requires physicians' awareness of its existence in our community and the use of Marbles' criteria obviates confusion with diabetes mellitus though it does not absolutely exclude Fanconi syndrome.
