There are several potential causes of metabolic alkalosis in children, including:
Vomiting: Loss of gastric acid can lead to a significant reduction in hydrogen ions, causing alkalosis. Diuretic Use: Certain diuretics promote renal excretion of hydrogen ions and potassium, leading to alkalosis. Congenital Adrenal Hyperplasia: This condition can alter the balance of electrolytes, potentially causing metabolic alkalosis. Chloride Deficiency: Low chloride levels can impair the kidneys' ability to excrete bicarbonate, contributing to alkalosis. Cystic Fibrosis: Excessive loss of chloride in sweat can also lead to metabolic alkalosis.
