Children who take steroid drugs for nephrotic syndrome do not suffer bone loss

Childhood nephrotic syndrome, which affects 3 out of 100,000 children, is the most common chronic kidney disease in children. Although it does not impair kidney function, it weakens the body's ability to remove water and salt from the blood, and causes swelling in the belly, legs, and around the eyes.
