Gitelman syndrome; Other names: Primary renal tubular hypokalemic hypomagnesemia with hypocalciuria: A model of transport mechanisms in the distal convoluted tubule.Sodium chloride (NaCl) enters the cell via the apical thiazide-sensitive NCC and leaves the cell through the basolateral Cl − channel (ClC-Kb), and the Na + /K +-ATPase.
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]
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]
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. [4] [5] [6]
Hypokalemic periodic paralysis is a condition that causes episodes of extreme muscle weakness typically beginning in childhood or adolescence. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Attacks cause severe weakness or paralysis that usually lasts from hours to days.
The signs and symptoms of refeeding syndrome can vary based on the severity of electrolyte disturbances, including weakness, arrhythmias, and respiratory difficulty. Hypophosphatemia, a key feature of refeeding syndrome, may lead to muscle weakness, heart failure, and impaired diaphragmatic function, while hypokalemia and hypomagnesemia can ...
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 ...
In the hospital setting this can commonly occur from nasogastric suction tubes. Severe vomiting also causes loss of potassium (hypokalemia) and sodium (hyponatremia). The kidneys compensate for these losses by retaining sodium in the collecting ducts at the expense of hydrogen ions (sparing sodium/potassium pumps to prevent further loss of ...
