- Cardiomyopathy
- Skin manifestation
Etiology of DKA.
Infection
Infarction
Intoxication
Inadequate insulin
Signs & Symptoms of DKA.
3P Weight loss Abdominal pain Nausea Vomiting Kussmalls breathing Ketones breath Tachycardia Tachypnea Dehydration Confusion Muscular weakness Dry skin
Diagnostic criteria for DKA.
Cbc -> hyperglycemia, hyperketonemia, WBC high
Urinalysis-> ketonuria, glucosuria
ABG -> ph low, HCO3 low
Ecg -> arrhythmia
Management of DKA
- Fluid + electrolytes
- Insulin
- Sodium bicarbonate
- Infection
Diagnostic criteria for HHS.
Osmolarity >360mosm/l
Glucose >360
Ph >7.5
Extreme dehydration
Signs & symptoms of hhs
Lethargy Polyuria Polydipsia Weakness Confusion Coma
Causes of hypoglycemia.
- Too much insulin intake
- Not eating enough
- Skipping meals
- Increasing exercise
Treatment of hypoglycemia in conscious person.
Oral sugar administration (simple carbohydrates)
Retest in 15’ to ensure Glucose >4.0 mmol + 15g carbohydrates
Eat usual snacks/meals with carbo and protein
Treatment of hypoglycemia in unconscious patient.
1mg glycagon SC/IM
Call
Symptoms of hypoglycemia
Neurogenic: tremor, sweating, hunger, nausea, palpitations
Neuroglycopenic: confusion, weakness, drowsiness, vision changes, dizziness, difficulty of speaking
Metabolic syndrome: Definition
A cluster of conditions that may cause heart disease, seizures
Causes of MS
Insulin resistance
Obesity
Inactivity
Diagnostic criteria for MS.
- abdominal obesity ( waist >40 m, >35 f inches )
- fasting glucose >100
- BP > 130/80
- triglycerides >150
- HDL <40 m, <50 f
Treatment for obesity
Lifestyle management
Orlistat drug (Xenical 120mg)
Bariatric surgery when bmi >40kg/m2
Treatment for dyslipidemia
Lifestyle adjustment
Statins (simvastatin 20-40mg, rosuvastatin -> crestor 20-40mg)
Nicotinic acid
Fibrates (fenofibrat lph 200mg)
Diagnosis for obesity
Height measurement
Weight measurement
Waist circumference
BMI
Diabetic retinopathy: pathology
High blood flow
High capillary permeability (leakage)
Basement membrane thickening
Signs of diabetic retinopathy
Neovascularization
Micro aneurysm
Edema
Cotton wool spots
Screening for Diabetic retinopathy
Visual acuity
Digital fundus photography
Exam fundus through dilated pupil
Treatment of diabetic retinopathy
Glucose control Htn control Ace inhibitors (captopril 12,5-25,50 mg) (lisinopril 10-20-40) Early detection Laser photo coagulation
Which are the acute complications for DM?
- Diabetic ketoacidosis
- Lactic acidosis
- Hyperglycemic hyperosmolar nonketonic state
- Hypoglycemia
Which is the first line treatment of DM2 + its side effects.
Metformin (biguanides) -> improves peripheral glucose uptake, high insulin sensitivity, low hepatic glucose production
Side effects: nausea, vomiting, flatulence, diarrhea, abdominal pain, lactic acidosis, weight loss
Side effects + mechanism of sulfanylureas + examples.
Increase the pancreatic secretion of insulin
Side effects: hypoglycemia, weight gain, renal impairment
1st: chlopropamide
2nd: glibenclamide, gliquidone, gliclazide
3rd: glimepiride
Meglitinides: side effects +mechanism
Repaglinide + nateglinide
Increased secretion if insulin
Side effects: hypoglycemia, weight gain
Thiazoladinediones: side effects, mechanism.
Decrease insulin resistance
Pyoglitazone + rosigitazone
Side effects: weight gain, hypoglycemia, heart failure, edema
Alpha glucosidase inhibitors: side effects, mechanism.
Acarbose
Blocks glucose absorption in the bowel
Take it before every meal
Side effects: flatulence, diarrhea, abdominal pain
Glucagon like peptide-1 : everything
Exenatide 2 injection/day
Mechanism: decrease glucagon release, decrease gastric emptying, improves insulin sensitivity
Side effects: weight loss, pancreatitis, nausea, vomiting, dyspepsia
SGLT-2: everything
Canagliflozin, dapagliflozin
Reduces renal tubular glucose re absorption
Side effects: polyuria, urinary infection, yeast infection, polydipsia
If kidney impairment, NOT recommended
Which of the drugs have as side effects weight loss?
Biguanides
GLP-1
