Type 1 Vs. Type 2 Flashcards
Ketoacidosis symptoms
Dehydration, tachycardia, orthostatic hypotension, and abdominal pain
Also may have fruity breath (acetone)
Presents with abrupt onset of illness and symptoms of hyperglycemia: Polyuria Polydipsia Hunger Weakness Unexplained weight loss
Type 1
Typical Type 1 presentation
<30 and lean
Type 2 presentation
Over age 40
Often incidental finding
Common characteristics with Type 2 diagnosis
Family history of diabetes
Excess body weight
Sedentary
Ethnic groups with higher incidence of Type 2
American Indians
Alaska natives
Hispanics
African Americans
Type 1 or 2: which results from autoimmune destruction of the beta cells in pancreas?
1
In Type 1, the destruction of beta cells in children is _____ and adults is ______.
Rapid in children and slower in adults
Type 1 are also prone to:
Hashimoto’s thyroiditis, Addison’s, vitiligo, celiac sprue, autoimmune hepatitis, pernicious anemia, and myasthenia gravis.
The first sign of Type 1 is often ________.
Ketoacidosis
Absence of endogenous insulin in Type 1 is manifested by low _____________.
C peptide levels
Type 1 or 2: characterized by insulin resistance and relative insulin deficiency
2
True or false: there is no autoimmune destruction of the pancreatic beta cells with Type 2
True
True or false: ketoacidosis is rare with Type 2
True
Risk factors for type 2
Increased age, obesity, sedentary, positive family history, personal gestational diabetes. Also, genetic predisposition.
What is MODY?
Maturity Onset Diabetes of Young, which is hyperglycemia in people under 25. Genetic defects of insulin action results in abnormal insulin receptors, leading to insulin resistance and hyperglycemia.
Why do Type 1 diabetics have a “honeymoon period?”
There is a temporary increase in endogenous insulin production due to decreased inflammation of the Islets of Langerhans (which was caused by initial autoimmune assault). Exogenous insulin is given and the inflammation goes down with beta cells resuming function. Autoimmune disease progresses, and eventually the revived cells lose function and the honeymoon is over
What is the length of the honeymoon period?
3 to 12 months.
More common in young adults than young children
What is the dawn phenomenon?
Normal hormonal fluctuations that trigger liver to release excessive glucose in the latter part of the nightly sleep cycle. (Causes elevated fasting glucose levels)
What medication is often used to treat dawn phenomenon?
Metformin, because it decreases glucose production by the liver.
What insulin is helpful for dawn phenomenon?
Long acting or a pump
What situations require careful adjustment of insulin related to the dawn phenomenon?
Those who work rotating shifts or suffer from jet lag
What is Somogyi Phenomenon?
Theoretical rebound effect of nocturnal hypoglycemia, where counter-regulatory hormones cause excess release of glucose from the liver to compensate.
How can Somogyi phenomenon be detected?
CGM (continuous glucose monitoring), or awaken at night to test blood sugar
