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
