Study Notes

Addison's Disease

  • Addison's disease, also called adrenal insufficiency, is a rare disorder
  • It occurs when the body does not produce enough cortisol and often too little aldosterone
  • It affects people of all ages and both sexes
  • It can be life-threatening

Addison's Disease - Etiology

  • Autoimmune attack on the adrenal gland
  • Tuberculosis (most common worldwide, but more common in developing countries)
  • Infections (AIDS, fungal)
  • Adrenal hemorrhage (caused by sepsis, meningitis)
  • Metastatic spread to the adrenals
  • Amyloidosis
  • Adrenalectomy
  • Genetic/congenital defects

Addison's Disease - Pathophysiology

  • Hyponatremia due to low cortisol, increasing vasopressin secretion/action and inability to excrete free water
  • Low aldosterone causing hyperkalemia
  • High adrenocorticotropic hormone (ACTH) due to low cortisol
  • Low glucose (cortisol stimulates glycogenolysis, increased glucagon release, and gluconeogenesis; low cortisol increases insulin sensitivity)

Addison's Disease - Nutrition

  • Higher sodium intake
  • Increased vitamin D and calcium intake if on high-dose corticosteroids
  • Lower potassium intake if necessary
  • Comfort foods (high simple sugars) if reported

Hypoglycemia - General

  • Diabetic and non-diabetic hypoglycemia
  • Failure of counter-regulatory mechanisms
  • Decreases in insulin production

Hypoglycemia: Aetiology & Pathophysiology

  • Hepatic glycogenolysis and low insulin levels are necessary for decreased insulin production
  • Plasma glucose levels decline, leading to increased hepatic gluconeogenesis and hepatic glycogenolysis
  • Glycogenolysis maintains serum glucose levels 8-12 hours until glycogen stores are depleted
  • Hepatic gluconeogenesis contributes to maintaining euglycemia
  • Pancreatic alpha cell secretion of glucagon is the next line of defense against hypoglycemia
  • Adrenomedullary measures can be necessary if glucagon fails to achieve euglycemia

Hypoglycemia - Non-Diabetic: Aetiology

  • Reactive hypoglycemia
  • Fasting hypoglycemia
  • Pre-diabetes or risk of diabetes
  • Stomach surgery
  • Rare enzyme deficiencies
  • Medicines (e.g., salicylates, sulfa drugs, quinine, pentamidine)
  • Alcohol (especially binge drinking)
  • Serious illnesses (e.g., liver, heart, kidneys)
  • Low levels of certain hormones (e.g., cortisol, growth hormone, glucagon, epinephrine)
  • Tumors (e.g., pancreas, IGF-II)
  • Inadequate food intake

Hypoglycemia - Non-Diabetic: Pathophysiology

  • Irregular or fast heartbeat
  • Fatigue
  • Pale skin
  • Shakiness
  • Anxiety
  • Sweating
  • Hunger
  • Irritability
  • Tingling or numbness of lips, tongue, or cheek
  • Confusion, abnormal behavior
  • Visual disturbances
  • Seizures
  • Loss of consciousness

Hypoglycemia - Non-Diabetic: Nutrition

  • Immediate treatment with 15 grams of carbohydrates (e.g., juice, glucose tablets, hard candy)
  • Frequent small meals and snacks throughout the day (every 3 hours)
  • Variety of foods including protein, dairy, high-fiber foods (e.g., whole-grain bread, fruit, vegetables)
  • Limit high-sugar foods

Hypoglycemia - Diabetic: Aetiology

  • Taking too much insulin or diabetes medication
  • Not eating enough
  • Skipping or postponing a meal or snack
  • Increased exercise or physical activity without adjusting intake
  • Drinking alcohol

Hypoglycemia - Diabetic: Pathophysiology

  • Similar symptoms to non-diabetic hypoglycemia

Hypoglycemia - Diabetic: Nutrition

  • Do not skip or delay meals/snacks
  • Be consistent with insulin/medication amounts and timing
  • Adjust medication or eat additional snacks if increasing activity levels
  • Eat a meal/snack with alcohol if drinking to avoid delayed hypoglycemia

Special Diets - General

  • Special diets are used to treat or prevent conditions
  • Specific modified diets include changes in texture, nutrient level, frequency/timing of meals, and exclusions
  • Examples include renal, heart health, malabsorption, and iron deficiency anemia diets

Special Diets - Renal Diet

  • Required for chronic kidney disease
  • Restricts protein and other nutrients (fluid, sodium, potassium, phosphorus)
  • Restriction increases as CKD progresses
  • Dialysis may be required at stage 5
  • Specific food lists for higher/lower phosphorus and potassium contents
  • Potential drug use (e.g., spironolactone)

Special Diets - Heart Health Diet

  • Primarily for post-onset metabolic syndrome management
  • Lower saturated fat, less than 7% of total calories
  • Increase polyunsaturated and monounsaturated fats (up to 10% and 20% of total calories, respectively)
  • Increase carbs (50-60% total calories) and fiber (20-30 grams per day)
  • Lower cholesterol, less than 200 mg/day, and sodium, less than 2,300 mg/day

Special Diets - Malabsorption Syndrome

  • Poor nutrient absorption (digestive or absorption impairment)
  • Can occur due to various issues (e.g., lactase activity reduction, coeliac disease)
  • Eat small frequent meals (5-6/day)
  • Reduce high-fat foods
  • Reduce/avoid high-fiber foods
  • Consider vitamin/mineral supplementation if necessary
  • Drink liquids between meals

Special Diets - Iron Deficiency Anemia

  • Low iron levels in the body
  • Poor iron absorption
  • Increased iron requirements
  • Increase heme iron-rich foods or dietary vitamin C
  • Iron supplements might be needed if diet is not sufficient
