Kidney Stones: Symptoms, Causes, Diagnosis, Treatment, and Prevention

What Are Kidney Stones?

Kidney stones are hard, pebble-like pieces that form in your kidneys. They develop when minerals and salts in your urine stick together. Because these stones can block the flow of urine, they may cause pain and other problems. Many people experience kidney stones at least once in their lives. According to the Centers for Disease Control and Prevention (CDC), kidney stones are a common health issue worldwide.

Common Symptoms of Kidney Stones

Kidney stone symptoms can vary. Sometimes, small stones cause no signs at all. However, larger stones may lead to noticeable problems. For example, you might feel severe pain or discomfort. Watch for these common signs of kidney stones:

Sharp pain in your back, side, or lower belly

Pain that comes and goes in waves

Pain while urinating

Pink, red, or brown urine (blood in urine)

Cloudy or foul-smelling urine

Feeling the need to urinate often

Urinating in small amounts

Nausea or vomiting

Fever and chills, if infection is present

Because these symptoms can also signal other health issues, it is important to pay attention to your body. If you notice any of these signs, you should seek medical advice.

Causes and Risk Factors

Kidney stones form when your urine contains more crystal-forming substances than your body can dilute. These substances include calcium, oxalate, and uric acid. Over time, they can clump together and create stones. Several factors can increase your risk:

Not drinking enough water

Eating a diet high in salt, sugar, or protein

Being overweight or obese

Having a family history of kidney stones

Certain medical conditions, such as diabetes or urinary tract infections

Some medications and supplements

Although anyone can get kidney stones, adults between ages 30 and 60 are most at risk. Men are also more likely to develop stones than women.

How Kidney Stones Are Diagnosed

Doctors use several methods to diagnose kidney stones. First, they will ask about your symptoms and medical history. Next, they may order tests to confirm the diagnosis. Common tests include:

Urine tests to check for blood or crystals

Blood tests to measure minerals and kidney function

Imaging tests, such as ultrasound or CT scans, to locate stones

Because early diagnosis helps prevent complications, it is important to see a doctor if you suspect kidney stones.

Treatment Options for Kidney Stones

Treatment for kidney stones depends on the size and type of stone. In many cases, small stones pass on their own with extra fluids and pain relief. However, larger stones may need medical help. Here are common kidney stone treatment options:

Drinking plenty of water to help flush out the stone

Pain relievers to manage discomfort

Medications to relax the urinary tract and help pass the stone

Shock wave therapy (lithotripsy) to break up larger stones

Ureteroscopy, where a thin tube removes or breaks up the stone

Surgery, in rare cases, for very large or stubborn stones

Because each case is different, your doctor will recommend the best treatment for you. If you are looking for kidney stone treatment options in your area, ask your healthcare provider for local resources.

Prevention Tips and Lifestyle Guidance

Although kidney stones can be painful, you can take steps to lower your risk. Simple changes in your daily habits may help prevent stones from forming. Try these tips:

Drink at least 8 to 10 glasses of water each day

Limit salt, sugar, and animal protein in your diet

Eat more fruits and vegetables

Stay at a healthy weight

Follow your doctor’s advice about supplements and medications

Because prevention is easier than treatment, make these habits part of your routine. For more ideas on how to prevent kidney stones, talk to your healthcare provider.

When to See a Doctor

Sometimes, kidney stones can cause serious problems. You should see a doctor right away if you:

Have severe pain that will not go away

Notice blood in your urine

Have trouble urinating

Develop a fever or chills

Feel sick to your stomach or vomit

Because early treatment can prevent complications, do not wait to get help if you have these symptoms.
