Diabetes Flashcards
What is Diabetes
Metabolic disorder characterized by hyperglycemia due to inability to produce/use insulin
Insulin
- Produced by beta cells in pancreas
- regulates metabolism of carbohydrates, fats, protein
- promotes absorption of glucose from the blood into liver, fat and skeletal muscle cells
- converted into glycogen, fat
Pathophysiology: lack of insulin/deficient action of insulin leads to abnormalities in carbohydrate, fat and protein metabolism. Results in glucose accumulation in tissue fluids and blood.
Types if Diabetes
Type 1 (5-10%)
beta cell destruction >>> absolute insulin deficiency
genetic / autoimmune / environmental (viruses)
common in children
Type 2
insulin resistance, relative insulin deficiency
Obesity most common cause
Gestational 5% pregnant women
Obesity = risk factor
Return to normal post partum but increased risk of DM later
Greater risk of miscarriage, larger size of fetus
Primary manifestation
- hyperglycemia
- ketoacidosis (fruity breath)
- vascular disease
- atherosclerosis (stroke, CVD #1 cause of death)
- retinopathy #1 cause of blindness,
- nephropathy #1 cause of renal failure
- peripheral artery dz (gangrene of extremities)
- neuropathy
- immunocompromised, poor wound healing.
Ketoacidosis: body breaks down fatty acids to ketone for energy because glucose cannot be properly absorbed into cells for utilization. Leads to metabolic imbalance
Signs/Symptoms
Type 1: polyuria, polydipsia, polyphagia.
Type 2: slight weight loss/gain, nausea, blurred vision
Diagnosis
Oral Manifestations
- Periodontal disease accelerated
- Gingival proliferations
- Infection
- Poor wound healing
- Xerostomia
- Oral ulcereations
- Candidiasis, Mucormycosis
- Numbing, burning, pain in oral tissues
Pharmacological Management
Type 1: Insulin injection/infusion
Type 2: Oral hypoglycemic agents (metformin, sulfonylureas), Insulin, lifestyle modification
Dental Management
Insulin Shock/Hypoglycemic Shock (Fast onset):
- Mild: Hunger, Weakness, Tachycardia, Pallor, Sweating
- Moderate: Incoherent, Uncooperative, belligerent, Poor orientation
- Severe: Unconsciousness, Tonic/Clonic movements, Hypotensive
Hyperglycemic Crisis (Slow onset):
Diabetic Ketoacidosis (DKA) – Insulin insufficiency, Excessive blood glucose, and Dehydration. Cells break down Fatty acids into ketone bodies/keto acids, blood pH drops, and excessive excretion of fluids/glucose.
Symptoms: Confusion, Hunger, Dehydration, “Fruity” smell breathe
Endodontic Literature
Fouad and Burleson 2003
PARL + Diabetes: lower success of NSRCT (impaired healing)
and greater flare-ups
