  2. Tumor lysis syndrome - Wikipedia

    en.wikipedia.org/wiki/Tumor_lysis_syndrome

    Potassium is mainly an intracellular ion. High turnover of tumor cells leads to spill of potassium into the blood. Symptoms usually do not manifest until levels are high (> 6.5 mmol/L) [normal 3.5–5.0 mmol/L] and they include [8] palpitations, cardiac conduction abnormalities, and arrhythmias (can be fatal) muscle weakness or paralysis

  3. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    These electrolytes must be replaced to keep the electrolyte concentrations of the body fluids constant. Hyponatremia, or low sodium, is the most commonly seen type of electrolyte imbalance. [12] [13] Treatment of electrolyte imbalance depends on the specific electrolyte involved and whether the levels are too high or too low. [3]

  4. Hyperphosphatemia - Wikipedia

    en.wikipedia.org/wiki/Hyperphosphatemia

    Hyperphosphatemia is an electrolyte disorder in which there is an elevated level of phosphate in the blood. [1] Most people have no symptoms while others develop calcium deposits in the soft tissue. [1] The disorder is often accompanied by low calcium blood levels, which can result in muscle spasms. [1]

  5. Magnesium deficiency - Wikipedia

    en.wikipedia.org/wiki/Magnesium_deficiency

    Deficiency of magnesium can cause tiredness, generalized weakness, muscle cramps, abnormal heart rhythms, increased irritability of the nervous system with tremors, paresthesias, palpitations, low potassium levels in the blood, hypoparathyroidism which might result in low calcium levels in the blood, chondrocalcinosis, spasticity and tetany, migraines, epileptic seizures, [7] basal ganglia ...

  6. Thyrotoxic periodic paralysis - Wikipedia

    en.wikipedia.org/wiki/Thyrotoxic_periodic_paralysis

    Hypokalemia (a decreased potassium level in the blood) is usually present during attacks. The condition may be life-threatening if weakness of the breathing muscles leads to respiratory failure, or if the low potassium levels lead to abnormal heart rhythms. [1] [2] If untreated, it is typically recurrent in nature. [1]

  7. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

  8. Paraneoplastic syndrome - Wikipedia

    en.wikipedia.org/wiki/Paraneoplastic_syndrome

    Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.

  9. Fluid balance - Wikipedia

    en.wikipedia.org/wiki/Fluid_balance

    Potassium is secreted into the tubule in exchange for the sodium, which is reabsorbed. The activated renin–angiotensin system stimulates the zona glomerulosa of the adrenal cortex which in turn secretes the hormone aldosterone. This hormone stimulates the reabsorption of sodium ions from distal tubules and collecting ducts. Water in the ...
