What happens to children with nephrotic syndrome when they grow up is related to the type of pathology and complications. If the type of pathology is good and there are no complications, there may be no significant effect on the child when he/she grows up, on the contrary, severe cases may develop renal failure at an early stage and may need lifelong dialysis treatment. The exact prognosis varies from person to person. Childhood nephrotic syndrome is a common renal disease in children, which is a group of clinical syndromes caused by a variety of reasons of increased permeability of glomerular basement membrane and loss of large amounts of plasma proteins from the urine, and the prognosis of this disease needs to be based on its clinicopathologic staging. Generally speaking, the most common subtype in children is microscopic lesion type, also known as lipoid nephropathy, which may have a relatively good prognosis after standardized treatment. However, some baby phenotypes may have a relatively poor prognosis and can progress to the stage of renal failure in a short period of time and may require lifelong dialysis treatment. If your child suffers from nephrotic syndrome, it is recommended to consult a doctor in time, under the guidance of the doctor, complete the relevant examinations, clarify the type of pathology, and at the same time clarify whether there are complications, and then follow the doctor’s instructions to be targeted treatment.
