How does glucose arrive in bloodstream?
-carbs eaten orally
-glucose released from stored glycogen in muscles and liver cells
-gluconeogenesis (newly made glucose made in pancreas or kidney cells)
If glucose levels fall low…
Insulin release is suppressed
Glucose remains in the bloodstream instead of being driven into the cells
Glucagon is released from the pancreatic alpha cells
Glucagon stimulates production and release of glucose from glycogen stores in the liver
Epidemiology of T1DM
Commonly diagnosed below age 30
Previously referred to as juvenile-onset diabetes
Affects more than 400,000 children under age 14
Pathophysiology of T1DM
Triggered by an autoimmune process, insulin-producing beta cells of the pancreas are destroyed
Results in a lack of insulin
Causes high blood sugar
Normal blood sugar levels?
60-100 mg/dL
How is insulin administered
ONLY by injection (subq) or IV
must be given with food to work off of
treatment for T1DM?
Insulin level is never zero
Modern insulin analogs and insulin pumps more closely mimic the actions of a healthy pancreas
3 methods of assessing glycemic control
Self-monitoring of blood glucose
Continuous blood glucose monitoring
Monitoring of HgbA1c
What are some complications related to T1DM and T2DM?
Diabetic ketoacidosis- inadequate insulin for normal glucose metabolism
Hypoglycemia- low blood sugar
Dawn phenomenon- blood sugar spikes in between the hours of 2-8AM
Somogyi effect-insulin lowers blood sugar but the body sends more glucose
Who is at a higher risk for diabetes?
People who are obese, African Americans, Native Americans, women with PCOS, Latinos, people with cardiovascular disease, people 45 or older, genetics with a history of diabetes, pregnant women or a woman who has given birth to a 9+ pound baby, people who are less active.
Epidemiology of T2DM
Growing epidemic in U.S.
In adults, type 2 accounts for 90%-95% of cases
More common in adults than in juveniles
Once called “adult-onset diabetes”
Risk factors involve genetics and lifestyle
Prediabetes is a warning sign for type 2 DM
The CDC estimated that 84.1 million had prediabetes and only 11% knew they had it.
DM Management
Pharmacological interventions and self-management
Many are overweight with insulin resistance
Advised to perform at least 150 min/week of moderate-intensity activity and strength training 3x/week
Increase water intake
Modify life style
