Proteinuria in Children

Proteinuria in Children – Symptoms, Prevention, and Reasons

Proteinuria in children, then the kidneys have very small blood vessels that filter water, salt, and waste products from the blood. These are known as spirals. They protect the proteins in the blood and promote the absorption of water into the tissues. An important function of proteins in the blood is to maintain body fluid levels.

Once these filters are broken, the protein can leak from the blood into the urine. This leads to Proteinuria, a disease associated with excessive amounts of protein in the urine in pediatric patients. Urinary Albuminuria or albumin are other names for Proteinuria. The extra protein in your baby’s urine is not visible. However, it can be associated with swelling of the ankles, feet, and eyelids.

What Is Proteinuria in Children?

Although Proteinuria is painless and generally harmless and can be caused by exercise, fever, or stress, it can also be a sign of latent kidney disease or a disease originating from another part of the baby’s body. Sometimes infections or chemicals damage the kidneys, which in turn affects kidney function. If there is an infection, the Proteinuria will be treated as the infection is treated. Urinary proteins can also be associated with type 1 and type 2 diabetes.

While your child is in the early stages of Proteinuria, your child will have no symptoms. As he progresses, there will be a significant amount of protein that will pass from the blood to the urine. It is then eliminated from the body. During this time, the following symptoms may occur, as large amounts of protein are excreted from the blood into the urine and then out of the body. The following signs and symptoms may occur which may indicate the development of kidney disease.

  • Difficulty breathing
  • Hypertension
  • Fatigue

Swelling (swelling), especially near the eyes, hands, feet, and then the navel. Urine that looks foamy or gaseous due to large portions of protein. For Proteinuria, prevention is not possible and this disease cannot be avoided. However, you can protect the health of your kidneys by drinking plenty of water every day, which will eliminate waste from your kidneys.

How Common Is Proteinuria in Children?

Doctors diagnosed 2 or 3 out of 100 children of any age with Proteinuria. In most cases, the Proteinuria is mild and harmless. About 1 in 100 children have persistent proteinuria, and this type of Proteinuria can be more severe.


Protein in the urine can be the result of mild health conditions or other medical conditions. Mild conditions may include:

  • Gravitational force
  • Lack of hydration
  • Aspirin treatment
  • Cold weather
  • Anxiety and stress
  • High body temperature
  • Protein is visible in the urine after intense exercise

Persistent Proteinuria May Indicate a Latent Disease Such as:

  • Nephrotic syndrome in childhood.
  • Glomerular disorders
  • Urinary tract infections
  • Immune system disorders such as Goodpasture’s syndrome or lupus
  • Heart diseases
  • Renal abnormality
  • Kidney cancer
  • Intravascular hemolysis (a condition in which red blood cells break down and hemoglobin is excreted into the bloodstream)
  • High levels of toxins
  • Acute renal failure
  • Hypertension

Signs and Symptoms:

Most children with Proteinuria have no symptoms. Normally you will not notice protein in the urine, but sometimes the urine looks sparkling. Proteinuria is painless. When the kidneys lose too much protein, it is called intermittent nephrotic proteinuria, which leads to nephrotic syndrome.

Babies often have swelling in the body, especially in the legs, feet, and face. Urine may be dark brown or red when there is a lot of blood, this is sometimes the case with Proteinuria. Children with asymptomatic proteinuria often have Orthostatic or transient types.

  • Repeated Urination
  • Muscle contractions (especially at night)
  • Foamy urine
  • Swollen eyelids, hands, and feet
  • Motion sickness
  • Loss of appetite

What Are the Possible Complications and Risk Factors for Proteinuria in Children?

Proteinuria Diagnosis

Some children may be at risk for Proteinuria due to the following factors.

  • Any heart disease
  • Hypercholesterolemia
  • Excess weight
  • High blood pressure
  • High cholesterol
  • Family history of chronic kidney disease
  • Problems with the urinary system or kidneys at birth

If your baby has high blood pressure and Proteinuria, he may have a stroke or heart attack. This increased pressure can lead to other chronic kidney diseases, including kidney failure.
Also, kidney problems and high blood cholesterol are not good symptoms because they can increase the baby’s risk of a heart attack.

Proteinuria Diagnosis:

Urine tests are done to determine the formation of protein in the baby’s urine. Since proteins can have a short shelf life in the urinary tract, urine samples from the early morning and those collected after this day can help with better understanding. Additionally, the following tests may be useful:

  • In the case of orthostatic proteinuria, the sample collected in then the morning will not contain proteins. If there are other symptoms, regular checks provide the value of a particular urinary protein.
  • Your pediatrician will also suggest a 24-hour urine collection to assess protein levels.
  • If your urine is high in protein, your pediatrician may suggest some tests for a better assessment. To check for obstructions or tumors, MRIs, CT scans, or imaging tests such as an ultrasound of the urinary tract and kidneys may be done.
  • Blood tests, glomerular filtration levels, and creatine levels can help determine kidney biopsy.

How Is Proteinuria Treated in Children?

Your baby does not need treatment:

  • Orthostatic proteinuria produces very little protein in then the kidneys during the day, especially after exercise or standing.
  • A soft protein that heals after the first urinalysis fever or urinary tract infections.

However, your child may need treatment:

  • Persistent proteinuria where proteinuria does not subside
  • Neurotic syndrome
  • Kidney damage is suspected

Sometimes a pediatrician will examine a baby’s urine after a few months to see if there is a reduction in the amount of protein in the urine. Thus, if the amount of protein in the urine does not change or the amount of protein is high, your doctor will refer you to a specialist nephrologist (nephrologist). A nephrologist can perform a kidney biopsy. . A way to solve the problem.

Regardless of the cause of the kidney problem, a few simple steps can be helpful for your baby. Reducing salt intake can reduce swelling. The drug can check for swelling (swelling) of the kidneys, which can cause the protein to enter the urine. Thus, it is very important to follow your doctor’s instructions, while it is also important to visit a doctor for regular check ups.

Prevention of Proteinuria:

Proteinuria can never be avoided or prevented. However, you can maintain good kidney health by drinking plenty of water every day and more fluids will clear than the waste from your kidneys. Lifestyle modifications and dietary changes are helpful if then the cause is high blood pressure, diabetes, or a kidney problem. Thus, it is also a good idea to consult a nephrologist regularly.
