Approach to Endocrine Topics I Flashcards
What is Diabetes Mellitus Type 2 and what does it lead to
can range from insulin resistance with relative insulin deficiency to a predominantly secretory defect with insulin resistance
- ineffective transport of glucose out of blood vessels
- Glucose levels rise in the blood (Hyperglycemia)
- Hyperglycemia leading to end organ damage
what are some risk factors for Diabetes Mellitus 2
- age over 45
- BMI over 25
- genetic
- Sedentary lifestyle
- High risk ethnicity
- Hypertension over 140/90
- Dyslipidemia
- HbA1c greater than 5.7, fasting glucose over 100
Clinical presentations of Diabetes Type 2
- Polyuria
- Polydypsia
- Polyphagia
rapid weight loss
- impaired healing
- fatigue
- acanthosis nigricans
- fruitybreath
- recurrent UTI
- Tingling, pain, numbness in extremities
what is the American Diabetes Association criteria for diagnosis
- HbA1c greater than 6.5 percent
- Fasting glucose over 126
- 2 hour glucose over 200 on oral glucose tolerance test
- Random glucose greater than 200 with classic symptoms of hyperglycemia
Diabetic foot exam
- Look callus/corn formation, breaks in skin, erythmea, dryness
- check pulses
- Check sensation, including vibratory sensation and monofilament testing
what is management of DM 2 look like
- Lifestyle changes
- oral metformin unless contraindicated
- other oral angents
- Insulin
- check HbA1c every 3 months while adjusting treatment, then every 6 months when stable
- make sure to control blood pressure and hyperlipidemia
what are 3 types of complication diseases associated with DM II
-Microvascular diseases
(retinopathy, nephropathy, neuropathy)
-Macrovascular diseases
(Myocardial infarction, stroke, peripheral vascular disease)
-Increase in infections, including unusual infections
(necrotizing fasciitis, malignant otitis externa)
What is Diabetic Ketoacidosis
DKA
- often associated with type 1, but can present in type 2
- mental changes
- Nausea, vomitting, abdominal pain
- signs of dehydration (decreased skin turgor, dry oral mucosa, tachycardia, hypotension)
- Kussmaul respirations
- fruity smelling breath (acetone)
Differences between DKA and HHS?
DKA:
- Hyperglycemia- blood glucose >200
- Metabolic acidosis -venous pH<7.3 or plasma bicarb<15
- Ketosis, ketones in blood or urine
HHS: Hyperosmolar hyperglycemic state
- marked hyperglycemia>600
- Minimal acidosis
- absent or mild ketosis marked elevation in serum osmolality >320
what is the DKA/HHS management of this illness
Admit to hospital for fluid and electrolyte correction
Generally need IV fluids, IV insulin, and potassium replacement
-DO not manage as out patient
What is Diabetes Mellitus Type 1
Immune mediated Beta cell destrction
-Common disease of CHildhood
what are the risk factors of DM type 1
Genetic susceptibility
Environmental trigger
Clinical Presentations of DM I
- Polydipsia
- Polyuria
- Weight loss with hyperglycemia and ketonemia or ketonria
- DKA
What are associated conditions with DM I and what is the management for DM I
Associated COnditions:
- Autoimmune thyroiditis
- Celiac disease
- Addisons disease
Management:
- Education
- INsulin
What is Metabolic Syndrome
A constellation of metabolic abnormalities that confer increased risk of cardiovascular disease (CVD) and Diabetes Mellitus
-greater prevelance with increased age
