Lecture 1: Approach to Endocrine Disorders I Flashcards
What defines Diabetes Mellitus Type II?
-Insulin resistance leading to hyperglycemia, leading to organ damage
About what percent of the US population is estimated to have diabetes?
8% of population with 25-40% undx
What are some risk factors for diabetes?
Age > 45 BMI > 25 family hx History of gestational diabetes Dyslipidemia HbA1c > 5.7 or fasting glucose > 100 Polycystic ovary syndrome History of vascular disease
What are some clinical presentations of diabetes?
Polyuria
Polydipsia
Polyphagia: excessive hunger
Rapid weight loss Fatigue Blurry vision Fruity breath Tingling pain in extremities
What is acanthosis nigricans?
Brown to black, poorly defined, hyperpigmentation of the skin normally found around neck, armpits, navel, and other body folds
Sign for diabetes
What criteria has to be met to diagnose diabetes according to ADA?
- HbA1c > 6.5%
- Fasting glucose > 126 mg/dL
- 2 hour glucose > 200 mg/dL on oral glucose tolerance test
- Random glucose > 200 mg/dL
Any one of these is enough for dm dx
What specific tests and exams would you perform, if you suspect a patient having diabetes?
- Fasting lipids
- Liver enzymes
- Renal function
- Microalbuminuria
- Dilated eye exam
- Foot exam
What do you check for diabetic foot exam?
- calluses, breaks in skin, erythema, and dryness
- also pulses, sensation and insurance coverage of diabetic footwear
What is the first course of tx for DM?
What is the follow up mgt for DM?
- Lifestyle changes
- Oral metformin
- Insulin
- Checking HbA1c levels every 3 months
- Smoking cessation
- Blood pressure control
- Hyperlipidemia control
What is DKA associated with?
usually Type 1, but can also happen in Type 2
What are symptoms of diabetic ketoacidosis?
- Mental changes
- Nausea, vomiting
- Abdominal pain
- Dehydration
- Kussmaul respirations (deep breathes/working hard to breathe)
- Fruity smelly breath
What is the difference between DKA and HHS (Hyperosmolar hyperglycemic state)?
DKA:
glucose >200, in metabolic acidosis with pH <7.3 and <15 bicarb + ketones in blood and urine]
HHS:
glucose >600 - marked hyperglycemia, minimal acidosis with pH > 7.3 and bicarb >15, absent or mild ketosis, >320 serum osmolality
How do you treat a patient for DKA?
Admit to hospital! do not send home!
-IV fluids, IV insulin, and potassium replacement
What is metabolic syndrome?
Cluster of conditions that occur together, increasing your risk of heart disease, stroke and type 2 diabetes
What are risk factors for metabolic syndrome?
- Overweight or obese
- Sedentary lifestyle
- Genetics
- Aging
