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]
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
Potassium deficiency: Mild low potassium does not typically cause symptoms. [27] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [21] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [21] [27]
Low GABA levels can lead to heightened stress, manifesting as overwhelming feelings, disorganization, excessive worrying, and insomnia due to racing thoughts. This deficiency is associated with ...
The Chvostek sign (/ ˈ k v ɒ s t ɪ k /) is a clinical sign that someone may have a low blood calcium level (a decreased serum calcium, called hypocalcemia).The Chvostek sign is the abnormal twitching of muscles that are activated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII).

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.
A new study suggests potassium supplementation after cardiac surgery is only needed if a patient has low potassium levels. This lower threshold could help decrease the risk of side effects and ...
This type of damage can typically be observed via a muscle biopsy. Not even anabolic steroids can repair this type of muscular damage. [citation needed] Life span is expected to be normal, [12] but attacks can drop potassium to levels low enough to cause life-threatening breathing problems or heart arrhythmia. Patients often report muscle pain ...
