Diabetes Mellitus Flashcards
Epidemiology (6)
- 18 million individuals diagnosed in the US
High risk groups
- African Americans
- Hispanics
- American Indians
- Asian Americans
Complications
6. Leading cause of blindness, end-stage renal disease, amputations, and infection; will be cumulative with duration of uncontrolled blood sugar
Fasting Plasma Glucose (FPG)
No caloric intake for at least 8 hourss
Oral Glucose Tolerance Test (OGTT)
Administration of glucose containing:
75 grams anhydrous glucose
1.75 g/kg of body weight to a maximum of 75 grams
Impaired Glucose Tolerance (IGT) (2)
- Measure of carbohydrate intolerance 2 hours following OGTT
- Also known as ‘Pre Diabetes’
Impaired Fasting Glucose (IFG)
Measure of disturbed carbohydrate metabolism
Classification
Type 1 Diabetes (T1DM) (3)
- Autoimmune destruction of B cells of the pancreas
- Onset usually preschool to teenage (can see neonatal diabetes)
- Antibody formation:
- Islet cells
- Glutamic acid decarboxylase
- Insulin
Classification Type 2 Diabetes (T2DM) (2)
- Insulin resistance and a relative lack of insulin secretion
- Metabolic Syndrome
- Hypertension
- Dyslipidemia
- Elevated plasminogen activator-1 inhibitors (PAI-1)
Miscellaneous Causes (6)
- Pancreatitis
- Cystic Fibrosis (CF-Related Diabetes)
- Cushing syndrome or medication induced
- Hyperthyroidism
- Infections (Congenital rubella or cytomegalovirus)
- Monogenic (Neonatal diabetes)
Associated with genetic syndromes (2) Other syndrome (1)
Associated with some genetic syndromes
- Down’s syndrome
- Prader-Willi syndrome
Other: Gestational diabetes
Screening by American Diabetes Association (5)
- Overweight (BMI > 85% percentile)
With at least two of the following:
- Family history
- Race (Native Americans, African Americans, Hispanic Americans, Asians/South Pacific Islanders)
- Signs of insulin resistance
- Screen every 2 years starting at 10 years of age or onset of puberty
Signs and Symptoms of DM (6)
- Polyuria, Polydipsia, Polyphagia
- Blurred vision
- Weight loss
- Fatigue
- DKA
- Slow healing wounds
Neuropathies (Microvascular) Diabetic (2)
- Sorbitol accumulation
2. Protein glycosylation (thickened basement membrane)
Neuropathies (Microvascular) Peripheral (2)
- Parathesia and pain
2. Begins in distal extremeties but progresses proximally
Neuropathies (Microvascular) Autonomic (6)
- Impotence
- Gastroparesis
- Diarrhea
- Neurogenic bladder
- Orthostatis
- Diminished response to hypoglycemia
Neuropathies (Microvascular) Retinopathy (6)
- Leading cause of new blindness
Retinal changes
- Microaneurysms
- Increased permeability
- Occlusion
- Proliferation of new blood vessels
- Cancers
Nephropathy (microvascular) (5)
- 30-40% of all diabetic patients may develop
- Proteinuria
- Decreased GFR
- Increased arterial blood pressure
- Microalbuminuria
Dyslipidemia (macrovascular) (4)
- Increased risk of coronary artery disease
- Goal LDL < 100 mg/dL
- Dietary intervention needed
- Statins should be considered; Age > 8 years
Hypertension (macrovascular) (4)
- Goal BP determined by age, gender, height
- Lifestyle modifications
- ACE Inhibitors drug of choice
- Renal protective effects
