diabetes Flashcards
Diabetes mellitus (diabetes)
A group of metabolic conditions characterized by a
* Deficiency of insulin
* Reduced sensitivity to insulin
* Combination of both
Insulin
-transports glucose into cells
-* A hormone produced by the pancreas
* Regulates glucose (sugar) metabolism
-devastating effects on multiple tissues and organ systems
Hyperglycemia
Resulting condition that is caused by the build up
of glucose in bloodstream due to lack of insulin
Type 1
Frequently occurs in children
Complete insulin deficiency, insulin replacement required
Type 1A associated with an autoimmune destruction of pancreatic beta cells
Type 1B lacking the same
Type 2 (Non–insulin-dependent or adult-onset)
Pancreas secretes insulin, resistance to insulin or insufficient amounts
Hyperglycemia
Typically obese individuals / occurs with increasing age
Gestational Diabetes
Transient; 1st appears during pregnancy
Typically requires no further treatment after delivery
Prediabetes (In-between zone)
Between normal blood glucose levels / meeting dx criteria for diabetes
Impaired fasting / tolerance glucose levels
Hygiene hypothesis
improved hygiene practices are decreasing childhood exposure to infectious agents and subsequent opportunities for immune system development leading to a rise in autoimmune diseases
Polydipsia
Polyuria
Polyphagia
in type 1
Increased thirst
Frequent urination
Increased hunger
Diabetic ketoacidosis
in type 1
Buildup of ketones in the bloodstream; life-threatening
Systemic complications: in type 2
Neuropathy
Retinopathy
Nephropathy
Nephropathy
-Disease of the kidneys caused by damage to the small blood vessels or to the units in the
kidneys that clean the blood
Retinopathy
- Disease of the retina which results in impairment or loss of vision
Neuropathy
-Disease or dysfunction of one or more peripheral nerves, typically causing numbness or
weakness.
Hyperglycemia
- Condition of too little insulin causing abnormally high blood glucose levels.
- Intensive insulin therapy slows the development of long-term
complications
Macrovascular
large blood vessels)
Peripheral artery disease
- Increased arterial blood flow to the extremities, stomach, and kidney
- Claudication (pain or discomfort during walking or exercise that resolves with rest)
- Resting pain
Microvascular complications
small vessel)
