Exam 5/6

• Three cardinal signs of DM

  • Polyuria (huge urine output)
  • Polydipsia (excessive thirst)
  • Polyphagia (excessive hunger and food consumption)
• Hyperinsulinism

  Excessive insulin secretion, resulting in hypoglycemia
• ADH

  Helps to avoid dehydration or water overload by preventing urine formation
• How ADH works

  1. With high solutes, ADH preserves water

  2. With low solutes, ADH is not released, thus causing water loss
• Alcohol


  Inhibits ADH release and causes copious urine output
• Leptin


  A hormone released by adipose tissue that helps regulate energy balance by inhibiting hunger and plays a role in regulating metabolism and body weight
