In recent years, the incidence of kidney stones in children has been on the rise, which has attracted widespread attention. Kidney stones not only bring pain to children, but may also affect their growth and development. So, why do children get kidney stones? This article will conduct a detailed analysis from aspects such as diet, living habits, genetic factors, etc., and provide structured data to help parents better understand this issue.
1. Dietary factors

Diet is one of the main causes of kidney stones in children. The following are common diet-related factors:
| factors | Description |
|---|---|
| High salt diet | Excessive salt intake increases the excretion of calcium in the urine and promotes stone formation. |
| high protein diet | Excessive intake of animal protein will increase the excretion of uric acid and oxalic acid, which can easily lead to the formation of stones. |
| low water intake | Insufficient drinking water leads to concentrated urine, and minerals are easily deposited to form stones. |
| high sugar drinks | Sugary drinks increase concentrations of calcium, oxalic acid, and uric acid in the urine. |
2. Living habits
Bad lifestyle habits may also increase a child's risk of kidney stones:
| habit | influence |
|---|---|
| lack of exercise | Sitting for long periods of time can cause urine retention and increase the risk of stones. |
| Hold in urine | Holding urine for a long time can easily lead to concentrated urine and mineral deposition. |
| Excessive calcium supplementation | Blind calcium supplementation may lead to excessive urinary calcium and the formation of stones. |
3. Genetic and disease factors
Some childhood kidney stones are related to genetics or disease:
| factors | Description |
|---|---|
| family history | Children with a family history of kidney stones are at higher risk. |
| Metabolic abnormalities | Metabolic diseases such as hypercalciuria and cystinuria can easily lead to stones. |
| Urinary tract malformations | Congenital structural abnormalities of the urinary tract may lead to urine retention and stone formation. |
4. Preventive measures
For the above reasons, parents can take the following measures to prevent kidney stones in children:
| measures | Specific methods |
|---|---|
| Eat properly | Control the intake of salt, sugar, and protein, eat more fruits and vegetables, and supplement with appropriate amounts of calcium. |
| Drink plenty of water | The recommended daily water intake is 3%-5% of body weight (such as 1-1.5L per day for a 30kg child). |
| Proper exercise | Ensure at least 1 hour of outdoor activity every day to promote metabolism. |
| Regular physical examination | Especially for children with a family history, it is recommended to have routine urine and B-ultrasound examinations every year. |
5. Recent hot topics
According to the hot topics on the Internet in the past 10 days, children’s health issues have attracted much attention:
| hot topics | Related content |
|---|---|
