Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
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]
Potassium leaks out of platelets after clotting has occurred. A high white cell count (greater than 120,000/microL) in people with chronic lymphocytic leukemia increases the fragility of red blood cells, thus causing pseudohyperkalemia during blood processing. This problem can be avoided by processing serum samples, because clot formation ...
The foods you eat impact your hydration levels, and high-sodium foods (like Mexican, hibachi grills, marinades, or pizza) require more water to counterbalance the higher amounts of sodium in your ...
A deficiency in potassium (hypokalemia) can lead to symptoms like fatigue, muscle weakness, and impaired cognitive function, including difficulty concentrating and memory problems. Guava Health ...
Hypoaldosteronism causes low sodium (hyponatremia), high potassium (hyperkalemia), and metabolic acidosis, a condition in which the body produces excess acid.These conditions are responsible for the symptoms of hypoaldosteronism, which include muscle weakness, nausea, palpitations, irregular heartbeat, and abnormal blood pressure.
Mild cases of metabolic alkalosis often cause no symptoms. Typical manifestations of moderate to severe metabolic alkalosis include abnormal sensations, neuromuscular irritability, tetany, abnormal heart rhythms (usually due to accompanying electrolyte abnormalities such as low levels of potassium in the blood), coma, seizures, and temporary waxing and waning confusion.
The condition is hypokalemic (manifests when potassium is low; not "causing hypokalemia") because a low extracellular potassium ion concentration will cause the muscle to repolarise to the resting potential more quickly, so even if calcium conductance does occur it cannot be sustained. It becomes more difficult to reach the calcium threshold at ...
