    Study Notes

    Addison's Disease

    • Addison's disease, also known as adrenal insufficiency, is a rare disorder.
    • It affects approximately 1 in 10,000 people.
    • Common symptoms appear between the ages of 30 and 50.
    • Women are more commonly affected.
    • The disease is caused by an autoimmune attack on the adrenal gland.
    • Other causes include tuberculosis, infections, adrenal hemorrhage, metastatic spread to adrenals, amyloidosis, and adrenalectomy.
    • Genetic defects are sometimes responsible.
    • The pathology results in decreased cortisol and aldosterone production.

    Hypoglycemia

    • Hypoglycemia is characterized by abnormally low blood glucose levels.
    • Failure of hypoglycemic counter-regulatory mechanisms is a key aspect of the pathology.
    • Hepatic glycogenolysis and low insulin levels are a first line of defense .
    • Decreasing insulin secretion can also occur as glucose levels decline.
    • Glycogenolysis can maintain blood glucose for 8-12 hours.
    • Hepatic gluconeogenesis plays a significant role in longer-term glucose regulation.
    • The drop in insulin production happens while blood sugar levels are in the low normal range—a unique aspect of hypoglycemia.
    • Glucagon secretion is the second line of defense.
    • Should glucagon fail, adrenomedullary measures may be employed.

    Special Diets

    • Special diets can be useful for a variety of conditions because they ensure each essential nutrient is delivered in the correct form (F), quantity (Q), and to the necessary location (W).

    • Renal Diet

      • Used for patients with chronic kidney disease.
      • Protein restriction is necessary along with limitations on fluid, sodium, potassium, and phosphorus.
      • Gradually more restrictive as kidney disease progresses.
      • Dialysis becomes necessary at later stages.

    • Heart Health Diet

      • LDL cholesterol plays a role in the atherosclerotic process or buildup of plaque in arteries.
      • Elevated LDL-c contributes to the process.
      • Eating a TLC diet may help manage the condition.
      • The goal is to adjust fat content to 25-35% of calories while keeping saturated fat under 7% of total calories and trans fat minimized.

    • Malabsorption Syndrome

      • Poor nutrient absorption results from impaired digestion or absorption.
      • This can be due to impaired lactase activity, celiac disease, or removal of parts of the small intestine due to disease or injury.
      • Eating small, frequent meals (5-6/day), avoiding foods high in fats, fibers, and sugar provides better absorption.

    • Iron Deficiency Anemia

      • Low iron levels within the body lead to anemia
      • Decreased hemoglobin production and consequently reduced oxygen transport contributes to fatigue.
      • Foods high in iron, such as red meat, seafood, beans, dark leafy green vegetables, dried fruits, and iron-fortified foods, are recommended in these diets.
      • Dietary supplements may be required depending on levels and severity
