Why Are Children Getting Kidney Stones? Uro-Oncologist Explains Causes, Warning Signs and Prevention
Kidney stones are often associated with adults, but they can also affect children. While kidney stones are less common in children than in adults, doctors are increasingly seeing cases linked to dietary habits, inadequate fluid intake, family history and certain medical conditions.
For parents, recognising the warning signs early is important because kidney stones can cause significant pain and, in some cases, lead to urinary complications.
What Causes Kidney Stones in Children?
Kidney stones form when certain minerals and salts in urine become concentrated and crystallise. Several factors can increase the risk in children.
1. Not Drinking Enough Water
One of the most important risk factors is inadequate hydration. When children do not drink enough fluids, their urine becomes more concentrated, making it easier for crystals to form.
Children who are physically active, play outdoors for long periods or live in hot and humid conditions may need additional fluids to stay adequately hydrated.
2. High-Salt and Processed Foods
A diet high in salt can increase the amount of calcium released into the urine, potentially contributing to stone formation. Frequent consumption of packaged snacks, instant foods, processed meals and salty fast foods may therefore increase the risk.
3. Too Many Sugary Drinks
Regular consumption of sugar-sweetened beverages may also contribute to an unhealthy dietary pattern associated with kidney stone risk. Encouraging children to choose water instead of sugary drinks can support overall urinary and metabolic health.
4. Family History
Children with a family history of kidney stones may have a higher risk of developing them. Certain inherited conditions can also make the body more likely to produce particular types of stones.
5. Certain Medical Conditions
Some metabolic and urinary disorders can increase the likelihood of stone formation. Recurrent urinary infections, abnormalities of the urinary tract and conditions that affect the way the kidneys process minerals may also play a role.
6. Obesity and Sedentary Lifestyle
Increasing childhood obesity has also been linked with a higher risk of kidney stones. A balanced diet, regular physical activity and adequate hydration can help reduce several risk factors.
What Warning Signs Should Parents Watch For?
Kidney stones do not always cause obvious symptoms in children. Depending on the stone’s size and location, symptoms may vary.
Parents should watch for:
- Severe or recurring pain in the back, side or lower abdomen
- Pain that may move toward the groin
- Pain or burning while urinating
- Blood in the urine
- Frequent or urgent urination
- Nausea or vomiting
- Fever or chills, particularly if accompanied by urinary symptoms
- Cloudy or foul-smelling urine
- Difficulty passing urine
- Unexplained irritability or crying, particularly in younger children
In some children, abdominal pain may be mistaken for a stomach problem. Persistent or unexplained pain should therefore not be ignored.
When Should Parents Seek Medical Attention?
A child with severe pain, blood in the urine, vomiting, difficulty passing urine or fever should be evaluated by a healthcare professional promptly.
Fever associated with urinary symptoms can be particularly concerning because an infection occurring alongside an obstructing stone may require urgent treatment.
How Are Kidney Stones Diagnosed in Children?
Doctors may begin with the child’s symptoms, medical history and family history. Urine and blood tests can help identify infection or abnormalities associated with stone formation.
Imaging may also be recommended. Ultrasound is commonly used to evaluate the urinary system in children, while additional imaging may be considered depending on the clinical situation.
If a child repeatedly develops stones, doctors may investigate whether an underlying metabolic or inherited condition is contributing to the problem.
Can Kidney Stones Be Prevented?
Prevention largely depends on the underlying cause, but healthy habits can make a significant difference.
Parents can encourage children to:
- Drink enough water throughout the day
- Avoid excessive salty and highly processed foods
- Limit sugary beverages
- Eat a balanced diet containing fruits and vegetables
- Maintain a healthy weight
- Stay physically active
- Follow medical advice if they have previously developed kidney stones
Children who have had a kidney stone may need personalised dietary or medical advice based on the type of stone and the results of their evaluation.
The Bottom Line
Kidney stones can occur in children, and lifestyle factors such as inadequate hydration and a high-salt diet may contribute to the problem. Family history and certain medical or metabolic conditions can also increase the risk.
Parents should pay attention to recurring abdominal or back pain, painful urination, blood in the urine, vomiting or fever. Early medical evaluation can help identify the cause, treat the stone and reduce the chances of recurrence.
