Electrolyte Imbalance in Infants

Overview

Electrolyte Imbalance in Infants

Electrolytes are minerals (sodium, potassium, calcium) dissolved in the fluids of our body. They play a critical role in maintaining water balance, transmitting nerve impulses, and muscle function. An infant's body, with its rapid metabolism and limited reserves, is extremely sensitive to any fluctuations in electrolyte balance.

Why is imbalance easy to develop in infants?

Most often, electrolyte imbalance is a direct result of conditions that cause significant fluid loss:

  • Gastroenteritis: With vomiting and diarrhea the child loses not only water but also a huge amount of sodium and potassium.
  • High fever: With fever fluid and salts are lost through sweat and rapid breathing.
  • Improper rehydration: Trying to give the child large amounts of plain water during illness without replenishing salts can "dilute" the blood and lead to a dangerous drop in sodium levels.

Symptoms and Consequences

The symptoms of imbalance are nonspecific and often masquerade as symptoms of the underlying illness. They include lethargy, irritability, muscle weakness, and in severe cases—arrhythmia and seizures. That is why, in conditions accompanied by fluid loss, it is crucial to use specialized oral rehydration solutions. Read about the general mechanisms in the article "Electrolyte Imbalance".
