Side effects can include gastrointestinal discomfort, including nausea and vomiting, diarrhea, and bleeding of the digestive tract. [medical citation needed]Overdoses cause hyperkalemia, which can lead to paresthesia, cardiac conduction blocks, fibrillation, arrhythmias, and sclerosis.
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 ]
Potassium-sparing diuretics act to prevent sodium reabsorption in the collecting tubule by either binding ENaCs (amiloride, triamterene) or by inhibiting aldosterone receptors (spironolactone, eplerenone). This prevents excessive excretion of K + in urine and decreased retention of water, preventing hypokalemia. [10]
Hypokalemic periodic paralysis (hypoKPP), also known as familial hypokalemic periodic paralysis (FHPP), [1] is a rare, autosomal dominant channelopathy characterized by muscle weakness or paralysis when there is a fall in potassium levels in the blood (hypokalemia).
Common symptoms include hypertension, hypokalemia, metabolic alkalosis, and low plasma renin activity. [ 1 ] DOC excess syndrome is an excessive secretion of 21-hydroxyprogesterone also called 11-Deoxycorticosterone from adrenal glands and may cause mineralocorticoid hypertension.
Correction with oral bicarbonate may exacerbate urinary potassium losses and precipitate hypokalemia. [13] As with dRTA, reversal of the chronic acidosis should reverse bone demineralization. [14] Thiazide diuretics can also be used as a treatment by making use of contraction alkalosis caused by them. [citation needed]
Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. This category formerly consisted solely of polystyrene sulfonate, a polyanionic resin attached to a cation, administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels).
The low-renin hypertension is often accompanied by hypokalemia due to urinary potassium wasting and metabolic alkalosis. These features of mineralocorticoid excess are the major clinical clues distinguishing the more complete 17α-hydroxylase deficiency from the 17,20-lyase deficiency, which only affects the sex hormones.
