Here’s why children and teens are experiencing what used to be mostly an adult-only problem.

When you think of kidney stones, you likely assume that this painful condition is something only adults have to deal with. But today, more kids and teens are experiencing this problem than ever before. Here’s some insight into what’s causing the rise in kidney stones in kids and teens and how we can better protect them from this condition.

What Are Kidney Stones?

Kidney stones are hard, pebble-like pieces that form in the kidneys. They’re made of minerals and salts, and when they grow large enough, they can cause a lot of pain. Symptoms include belly or back pain, blood in the urine and trouble peeing.

Why Are Kidney Stones Becoming More Common in Kids?

Experts have noticed that kidney stones are on the rise among children and teens. Here’s why:

  1. Dietary changes: Many kids today eat a lot of processed foods, which are often high in salt. Too much salt in the diet can lead to kidney stones. Sugary drinks like sodas and juices can also be a problem because they reduce water intake and increase the risk of stone formation.
  2. Dehydration: Kids aren’t drinking enough water. Whether it’s because they’re busy with school, sports or screen time, many children don’t hydrate enough. When the body doesn’t get enough water, urine becomes more concentrated, making it easier for stones to form.
  3. Health conditions: Certain medical conditions, such as obesity and some genetic disorders, can make kids more likely to develop kidney stones. These conditions can change how the body handles minerals, leading to kidney stone formation.

How Can You Protect Your Kids from Kidney Stones?

The good news is that kidney stones are often preventable. Here’s how parents and kids can work together to reduce the risk:

  1. Encourage drinking more water: The best way to prevent kidney stones is to drink plenty of water. Make it a habit to sip water throughout the day, especially during activities like sports.
  2. Limit salt and sugar intake: Cutting back on salty snacks and sugary drinks can go a long way. Swap chips and sodas for healthier options like fruits, vegetables and plain water or seltzer.
  3. Stay active: Regular exercise is important for overall health and can help prevent conditions like obesity, which are linked to kidney stones.
  4. Talk to a doctor: If your child has symptoms like severe belly pain or blood in their urine, it’s time to see a doctor. Early diagnosis and treatment of kidney stones can make a difference.

Although kidney stones in kids are becoming more common, they’re not inevitable. With healthier habits and a little awareness, families can help prevent this painful condition. Encourage your child to drink water, eat balanced meals and stay active. These small changes can lead to big health benefits—and fewer kidney stones.
