What are the symptoms of chronic renal failure in children?

Generally, children with chronic renal failure may experience symptoms such as edema, hypertension, anemia, electrolyte imbalance, and delayed growth and development. A detailed analysis is as follows:

1. Edema

Due to reduced kidney function, the child's body cannot normally excrete water, leading to fluid retention and the formation of edema. The child may develop generalized or localized swelling, especially around the eyelids, face, and lower limbs.

2. Hypertension

Chronic renal failure causes decreased excretion of sodium and water by the kidneys, leading to sodium and water retention and increased blood volume, which results in persistently elevated blood pressure in the child. This may be accompanied by symptoms such as headache and dizziness.

3. Anemia

With chronic renal failure, the kidneys produce less erythropoietin, leading to insufficient red blood cell production and resulting in anemia. The child may appear pale, with pale lips and nails, and may also experience symptoms such as fatigue and dizziness.

4. Electrolyte Imbalance

With chronic renal failure, the kidneys' ability to excrete and regulate electrolytes is impaired, leading to disturbances in electrolyte balance. The child may develop symptoms such as hypocalcemia, hyperphosphatemia, and hyperkalemia.

5. Delayed Growth and Development

Chronic renal failure leads to the accumulation of metabolic waste and toxins in the child's body, negatively affecting growth and development. The child may experience slow increases in height and weight, and intellectual development may also be affected.

Maintaining healthy lifestyle habits in daily life, avoiding excessive intake of high-salt, high-sugar, and high-fat foods, and increasing consumption of foods rich in vitamins and fiber, such as vegetables and fruits, can help maintain good health.
