1. Hormones are chemical messengers that trigger intracellular responses
2. Types of Hormones o Peptide Hormone
o Amine Hormones
o Steroid Hormones
o Fatty Acid derivative
3. Communication with hor- o Autocrine
mones o Paracrine
o Endocrine
4. Diabetes Insipidus (DI) A disorder characterized by insufficient production or response to
antidiuretic hormone (ADH), leading to excessive urine output and
dehydration
"D I = dry inside"
5. Risk factors of diabetes in- • Central DI: Brain tumors, head trauma, pituitary surgery, infec-
sipidus tions (e.g., meningitis, encephalitis).
• Nephrogenic DI: Chronic kidney disease, medications (e.g., lithi-
um, demeclocycline), hypercalcemia, hypokalemia
• Dipsogenic DI: Psychological conditions, hypothalamic dysfunc-
tion
6. Patho of Central DI Dysfunction in the hypothalamus or pituitary gland leads to defi-
cient ADH secretion, preventing water reabsorption in the kidneys.
7. Patho of Nephrogenic DI Kidneys fail to respond to ADH due to genetic mutations, drugs
(e.g., lithium), or electrolyte imbalances.
8. Patho of Dipsogenic DI Excessive fluid intake due to hypothalamic dysfunction suppresses
ADH secretion

Clinical manifestations of • Polyuria (excessive urination, >3L/day)
diabetes insipidus • Polydipsia (excessive thirst)
• Nocturia (frequent urination at night)
• Dehydration signs: Dry skin, hypotension, tachycardia
• Neurological symptoms (in severe dehydration):
• Irritability, confusion, seizures
10. Diagnostics/Labs of dia- • Urine Specific Gravity: Low
betes insipidus • Serum Osmolality: High
• Urine Osmolality: Low
• Serum Sodium: High
• ADH levels: Low in Central DI, normal/high in Nephrogenic DI
11. Treatment for diabetes in- • Central DI: Desmopressin (DDAVP) (synthetic ADH)
sipidus • Nephrogenic DI: Thiazide diuretics, NSAIDs (Indomethacin),
low-sodium diet
• Dipsogenic DI: Fluid intake management, treatment of underly-
ing psychological disorders
12. Nursing interventions for • Monitor fluid balance (intake/output, daily weights)
diabetes insipidus • Assess vital signs (BP, HR for dehydration)
• Monitor electrolytes (Na+, K+)
• Administer medications as prescribed (DDAVP for Central DI,
diuretics for Nephrogenic DI)
• Education on diet modification (low-sodium diet in Nephrogenic
DI)
• Encourage hydration based on need
13. Education for diabetes in- • Recognizing symptoms of dehydration and overhydration
sipidus • Medication adherence (DDAVP for Central DI, thiazides for
Nephrogenic DI)
• Fluid management: Avoid excessive intake in Dipsogenic DI
• Regular monitoring of weight and urine output
