Diabetes Flashcards
3 components to exam for patients with diabetes
glucose abnormalities, autonomic neuropathy, vascular complications
Where are the insulin receptors primarily reside?
muscle cell.
How do you diagnose diabetes
2 consecutive high fasting glucose levels.
oral glucose tolerance test
fast for 8 hours. then orally drink sugary drink. Then they monitory your blood glucose incrementally for 8 hours.
HbA1c
a way to monitor how well pts are monitoring diabetes. Measure of long term glucose control. over the last 3 mo
normal fasting blood glucose
80-100 mg/DL
diabetic fasting blood glucose
+126 mg/DL
hypoglycemia
lethargic, drowsy, downregulation of the nervous system, confusion, irritability. Wendy is more concerned with hypo than hyper. easier to quick fix hyperglycemia.
Diabetes target goals
HbA1c <7%, BP-135/80, Blood glucose 70-130 before meals.
T/F huge effect on HbA1c with exercise
T. especially long term.
Ketoacidosis
Occurs when there is not enough insulin (usually type 1). Body still needs glucose for energy but insulin is not available for glucose metabolism.
Early sign of ketoacidosis
thirst, dry mouth, frequent urination, high blood glucose levels, high urine ketone levels, sweet breath
Later signs of ketoacidosis
constant fatigue, dry or flushed skin, nausea, vomiting, abdominal pain, difficulty breathing, difficulty concentrating, confusion.
elevated resting heart rate or orthostasis could indicate
autonomic neuropathy
autonomic neuropathy
damage to sympathetic/parasympathetic nerves
with diabetes there is a low grade inflammatory component that make nerves
hyper excitable
High levels of glucose ends up damaging
nerves (smallest to largest)
damage to autonomic system causes increase in
blood pressure
If the autonomic system is compromised, we know that
peripheral nerves are starting to go or will soon
gait analysis autonomic neuropathy
weaving
macrovascular complications of diabetes
coronary artery disease, peripheral arterial disease, stroke
microvascular complications of diabetes
nephropathy, neuropathy, retinopathy
