Diagnosis and Symptoms
Question from Orlando, Florida, USA:
Can you tell me what diseases or conditions can be misdiagnosed as Type 1 diabetes?
Diabetes mellitus is the only condition in childhood that causes weight loss, excessive urination and thirst. Glucose in the urine can be related to a number of kidney conditions but the blood sugar is normal. Thirst and excessive urination can be associated with drinking too much and a rare condition called diabetes insipidus — again the blood sugar is normal. A single high blood sugar may be found during stress — e.g., severe pain or fear — but the other symptoms are missing.
