👉 Azotaemia is an electrolyte deficiency caused by a decrease in the concentration of sodium ions (Na+) and chloride ions (Cl-) in the blood. It occurs when there is a discrepancy between the amount of these ions in the body and their normal levels, leading to a condition where these ions are not able to properly transport their proper function across the cell membrane. This can lead to various symptoms such as muscle weakness, confusion, and even death if left untreated.
