Description: An elderly man arrives at the hospital severely dehydrated. The physicians find that there is glucose in his urine and that his blood glucose does not decline much upon administration of an insulin shot. What is he likely to be suffering from? a. type 1 diabetes mellitus b. type 2 diabetes mellitus c. diarrhea d. gastric ulcer

Key Concepts

Glycosuria

Glycosuria is the presence of glucose in the urine, which typically occurs when blood glucose levels exceed the renal threshold for glucose reabsorption. It is an important clinical sign of diabetes mellitus, indicating that the body is unable to regulate blood sugar levels effectively.

Insulin Resistance

Insulin resistance occurs when body tissues, particularly muscle, fat, and liver cells, do not respond effectively to insulin, resulting in decreased glucose uptake from the bloodstream. This condition is a key feature of type 2 diabetes and contributes to persistently high blood sugar levels even in the presence of insulin.

Diabetes Mellitus

Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia due to defects in insulin secretion, insulin action, or both. It encompasses conditions in which blood glucose levels become abnormally high, leading to various complications if not properly managed.

Type 2 Diabetes Mellitus

Type 2 diabetes mellitus is a form of diabetes marked primarily by insulin resistance, where the body's cells do not adequately respond to insulin, and by a relative insulin deficiency. It is most common in older adults and is associated with symptoms like dehydration and hyperglycemia that lead to downstream effects including glycosuria.
