Hyperglycemia Flashcards
Increased serum glucose concentration value:
> 90 mg/dL
This can lead to impaired insulin production due to toxicity to beta cell
Chronic hyperglycemia
General Laboratory findings in Hyperglycemia: (5)
Increased urine and serum glucose
Increased urine specific gravity
Ketones in urine and serum (DM Type I)
Decreased blood and urine pH (acidosis)
Electrolyte imbalance (↓Na+, ↑K+, ↓HCO3)
A group of metabolic disorders characterized by hyperglycemia resulting from defects in insulin secretion, insulin receptors or both.
Diabetes mellitus
FBS level to confirm DM
≥ 126 mg/dL on more than one testing
Renal threshold for glucose
160-180 mg/dL
Normal Ratio of Ketones (Β-hydroxybutyrate to Acetoacetate):
1:1
Ratio of ketones in severe DM
6:1
How is ketosis reversed?
Insulin administration
General signs and symptoms of DM: (7)
Polyuria
Polydipsia
Polyphagia
Rapid weight loss
Hyperventilation
Mental confusion
Possible loss of consciousness
