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]
Some patients also take potassium-sparing diuretics such as spironolactone to help maintain potassium levels. [11] Paralysis attacks can be managed by drinking one of various potassium salts dissolved in water (debate exists over which, if any one in particular, is best used, but potassium chloride and bicarbonate are common).
A complete metabolic panel (CMP) or basic metabolic panel (BMP) can be used to evaluate serum electrolyte levels. Electrolyte measurement and aldosterone levels can be done via urine. [16] The pathognomonic clinical markers include low serum levels of potassium, sodium, chloride, and magnesium in the blood as a result of urinary excretion. [19]
Some guidelines recommend a bolus (initial large dose) of insulin of 0.1 units of insulin per kilogram of body weight. This can be administered immediately after the potassium level is known to be higher than 3.3 mmol/L; if the level is any lower, administering insulin could lead to a dangerously low potassium level (see below).

Bartter syndrome (BS) is a rare inherited disease characterised by a defect in the thick ascending limb of the loop of Henle, which results in low potassium levels (hypokalemia), [2] increased blood pH , and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic.
Hyponatraemia (low sodium level in the blood) and hypokalaemia (low potassium levels)—these are both common in those taking diuretics, often used for the treatment of ascites; furthermore alkalosis (decreased acid level), hypoxia (insufficient oxygen levels), dehydration: Drugs and medications
In rare cases, people taking escitalopram may be advised to take a benzodiazepine along with the medication for the first few weeks, as benzodiazepines can help reduce the early adverse effects of ...
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 ...
