Overview

Hyponatremia is caused by either increase ADH action/ secretion or kidney function impairment. SIAD is the most common cause of euvolemic hyponatremia. After SIAD, polydipsia, drugs and clinical disorders are the most encountered etiologies in clinical practice.

Causes

To review the mechanisms of developing hyponatremia, click here.

  • Etiologies of SIAD:
Conditions
Malignant disorders Carcinoma: Lung ( small cell carcinoma, mesothelioma), oropharynx, stomach, duodenum, pancreas, ureter, bladder, prostate, endometrium, thymoma

Lymphomas

Sarcomas: Ewing's sarcoma

Olfactory neuroblastoma

Pulmonary diseases Infections: Bacterial pneumonia, viral pneumonia, pulmonary abscess, tuberculosis, aspergillosis

Others: Asthma, cystic fibrosis, respiratory failure, emphysema, COPD,coronavirus disease, positive-pressure ventilation

CNS disorders Infections: Encephalitis, meningitis, brain abscess, RMSF, AIDS, malaria

Vascular and SOP: Subarachnoid hemorrhage, stroke, brain tumors, head trauma

Others: Hydrocephalus, cavernous sinus thrombosis, Multiple sclerosis, Guillain–Barré syndrome, Shy–Drager syndrome,

delirium tremens, acute intermittent porphyria, chronic psychosis, pituitary stalk section, transsphenoidal adenomectomy

Other causes Hereditary: Gain-of-function mutation of V2 receptors

Idiopathic

Drugs

Transient: Exercise, general anesthesia, nausea, pain, stress


  • Causes of acute hyponatremia: (develops in < 48 hrs)
Etiology
  • Post operative phase
  • Transurethral or endoscopic procedure (mannitol, sorbitol, glycine)
  • Colonoscopy preparation 
  • Polydipsia
  • Exercise
  • Oxytocin
  • Cyclophosphamide
  • Ecstasy( 3,4-Methylenedioxymethamphetamine, MDMA)
  • Thiazide
  • Halopridol
  • Recently started desmopressin, terlipressin, vasopressin

( Etiologies that cause hyperacute and acute hyponatremia are applicable to each category interchangeably depending on the onset of symptoms)

  • Causes of Hyponatremia based upon Serum Osmolality:
Classification Serum Osmolality Etiology
Hypertonic or Isotonic Hyponatremia > 295 mOsm/kg Hyperglycemia‡, Mannitol, Glycine, Maltose, severe azotemia
Isotonic Hyponatremia

(Pseudohyponatremia)

275 – 295 mOsm/kg Lab/blood draw error, Post TURP (bladder irrigation with osmotic solutions),

intravenous immunoglobulin (IVIg), Hyperlipidemia ( triglyceride, cholesterol ),

hyper paraproteinemia (monoclonal gammopathy of undetermined significance (MGUS),

multiple myeloma),

Hypotonic Hyponatremia < 275 mOsm/kg Glycerol, Sorbitol, Etiology depends upon volume status (Hypervolemic/ Euvolemic/ Hypovolemic)
Alcohol, Urea, Ethylen glycol are ineffective osmoles, cause hyperosmolar isotonic serum but not hyponatremia.

‡ Hyperglycemia causes osmotic diuresis results in a rise in serum sodium concentration, on the other hand it leads to extracellular shift of water due to osmotic gradient which causes relative hyponatremia , depends on which effect is stronger, there would be hypertonicity or hypotonicity[1].   

  • Causes of Hyponatremia based on volume status [2] :
Volume status Sodium status Causes
Hypovolemic

Hyponatremia[3]

  • total body water ↓
  • total body sodium ↓↓
  • GI loss: Vomiting, diarrhea, tube drainage
  • Insensible loss: Sweating, burns
  • Renal loss: Salt-wasting nephropathy (inappropriate loss of Na+-Cl– in the urine),

bicarbonaturia ( renal tubular acidosis, metabolic alkalosis), osmotic diuresis, diuretic use,

cerebral salt-wasting syndrome (Stroke ,SAH ,↑ brain natriuretic peptide and ↑ renal sodium loss )

  • Excessive diuretic administration: mostly thiazide diuretics
Hypervolemic

Hyponatremia

  • total body water ↑↑
  • total body sodium ↑
  • Renal disease: Acute or chronic kidney disease or injury

(due to relatively higher water versus salt intake and poor excretion), nephrotic syndrome

  • Congestive heart failure
  • Cirrhosis
  • Iatrogenic
Euvolemic

Hyponatremia

  • total body water ↑
  • total body sodium ↔

postoperative nausea, pain, stress, neoplasia (common), trauma, pregnancy)

, nephrogenic SIAD (Gain-of-function mutation of v2 receptors)

  • High fluid intake: Physical activity, surgery, primary polydipsia, potomania, tea & toast diet

(caused by a low intake of solutes with relatively high fluid intake)

  • Reset osmostat † : Drugs, pregnancy
  • Iatrogenic

† Altered sensitivity to serum osmolality by the hypothalamic osmoreceptors

  • Drugs which cause hyponatremia:
Drug Mechanisms [4] Drug Classification
Increase ADH secretion Antidepressants:Tricyclic antidepressants ( Amitryptiline,

Protriptyline, Desipramine),Selective serotonin reuptake inhibitors,

Monoamine oxidase inhibitors

Antipsychotic drugs: Phenothiazines (Thioridazine, Trifluoperazine),

Butyrophenones (Haloperidol)

Antiepileptic drugs: Carbamazepine, Oxcarbazepine, Sodium valproate

Anticancer agents: Vinca alkaloids (Vincristine, Vinblastine),

Platinum compounds (Cisplatin, Carboplatin)

Alkylating agents: Intravenous Cyclophosphamide, Melphalan, Ifosfamide

Miscellaneous: Methotrexate, Interferon, Levamisole, Pentostatin, Monoclonal antibodies, MDMA, Nicotine

Opiates

Increase ADH effect Antiepileptic drugs: Carbamazepine, Lamotrigine

Antidiabetic drugs: Chlorpropamide, Tolbutamide

Anticancer agents: Alkylating agents (Intravenous cyclophosphamide)

NSAIDS

Drugs affecting water and sodium homeostasis Diuretics: Thiazides, Indapamide, Amiloride, Loop diuretics
Reset omostat ‡ Antidepressants: Venlafaxine

Antiepileptic drugs: Carbamazepine

Vasopressin analogues Desmopressin, oxytocin, terlipressin, vasopressin

‡ Altered sensitivity to serum osmolality by the hypothalamic osmoreceptors
