  2. Syndrome of inappropriate antidiuretic hormone secretion

    en.wikipedia.org/wiki/Syndrome_of_inappropriate...

    In severe or acute hypoosmolar hyponatremia, swelling of brain cells causes various neurological abnormalities, which in severe or acute cases can result in convulsions, coma, and death. The symptoms of chronic syndrome of inappropriate antidiuresis are more vague, and may include cognitive impairment , gait abnormalities , or osteoporosis .

  3. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    Severity of symptoms is directly correlated with severity of hyponatremia and rapidness of onset. [3] General symptoms include loss of appetite, nausea, vomiting, confusion, agitation, and weakness. [14] [3] More concerning symptoms involve the central nervous system and include seizures, coma, and death due to brain herniation.

    More severe hyponatremia (levels less than 120 mEq/L), particularly if it develops rapidly (defined as occurring over less than 48 hours), can cause confusion, seizures and even lead to death ...

  5. Hyponatremia - Wikipedia

    en.wikipedia.org/wiki/Hyponatremia

    The causes of and treatments for hyponatremia can only be understood by having a grasp of the size of the body fluid compartments and subcompartments and their regulation; how under normal circumstances the body is able to maintain the sodium concentration within a narrow range (homeostasis of body fluid osmolality); conditions can cause that ...

  6. Hypotonic hyponatremia - Wikipedia

    en.wikipedia.org/wiki/Hypotonic_hyponatremia

    Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used. [2] When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.

    Symptoms of hypoventilation and breathing malfunctions typically present after the rapid weight gain. Some patients may initially develop obstructive sleep apnea, which is common in obese children. [3] Obstructive sleep apnea is the most common form of sleep apnea, and causes breathing to abruptly stop and begin again during sleep.

  8. Congenital adrenal hyperplasia due to 21-hydroxylase deficiency

    en.wikipedia.org/wiki/Congenital_adrenal...

    Aldosterone insufficiency in salt-wasting CAH results in significant loss of sodium in the urine. Urinary sodium concentrations may exceed 50 mEq/L. Due to the loss of salt at that rate, the infant is unable to maintain proper blood volume and begins to suffer from dehydration due to hyponatremia by the end of the first week of life.

  9. Pituitary apoplexy - Wikipedia

    en.wikipedia.org/wiki/Pituitary_apoplexy

    Hyponatremia, an unusually low level of sodium in the blood that may cause confusion and seizures, is found in 40% of cases. This may be caused by low cortisol levels or by inappropriate release of antidiuretic hormone (ADH) from the posterior pituitary. [1]
