Understanding Kidney Stones: Causes, Symptoms, and Effective Treatment Options

What Are Kidney Stones?

Kidney stones are hard deposits that form inside your kidneys. They are made from minerals and salts. Often, these stones can cause pain as they move through your urinary tract. Because kidney stones are common, many people want to know how to prevent and treat them. According to the CDC, kidney stones affect about 1 in 11 people in the United States.

Causes of Kidney Stones

There are several reasons why kidney stones form. Sometimes, your urine contains more minerals than your body can dissolve. As a result, these minerals stick together and form stones. Other times, not drinking enough water can make your urine too concentrated. This also increases the risk of stones. Here are some common causes:

Not drinking enough water

Eating a diet high in salt, sugar, or protein

Obesity or being overweight

Family history of kidney stones

Certain medical conditions, like diabetes or infections

Some medicines can also increase your risk

Because causes can vary, it is important to know your risk factors.

Symptoms of Kidney Stones

Kidney stone symptoms can be mild or severe. Sometimes, you may not notice any signs until the stone moves. However, when symptoms appear, they can be very painful. Common symptoms include:

Sharp pain in your back, side, or lower belly

Pain while urinating

Blood in your urine (it may look pink or red)

Frequent urge to urinate

Cloudy or foul-smelling urine

Nausea or vomiting

Fever and chills, if there is an infection

Because these symptoms can also mean other problems, it is wise to see a doctor if you notice them.

How Kidney Stones Are Diagnosed

Doctors use several tests to diagnose kidney stones. First, they may ask about your symptoms and medical history. Next, they may check your urine and blood for signs of stones. In addition, imaging tests help find the size and location of the stone. Common tests include:

Urine tests to check for minerals and blood

Blood tests to look for high levels of calcium or uric acid

CT scans or X-rays to see the stone inside your body

Ultrasound, which uses sound waves to find stones

Because early diagnosis helps prevent problems, do not wait if you have symptoms.

Treatment Options for Kidney Stones

Treatment for kidney stones depends on the size and type of stone. Sometimes, small stones pass on their own. In these cases, drinking plenty of water and taking pain medicine may be enough. However, larger stones may need more help. Treatment options include:

Drinking extra fluids to help pass the stone

Pain relievers to manage discomfort

Medicines to relax the muscles in your urinary tract

Shock wave therapy to break up stones (called lithotripsy)

Ureteroscopy, where a thin tube removes or breaks the stone

Surgery, in rare cases, for very large stones

Because each case is different, your doctor will choose the best treatment for you.

Prevention Tips for Kidney Stones

Preventing kidney stones is possible with some simple steps. While not all stones can be avoided, these tips can lower your risk:

Drink at least 8 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 if you have a history of stones

Take medicines as prescribed to prevent stones

Because prevention is easier than treatment, start these habits early.

When to See a Doctor

Sometimes, kidney stones can cause serious problems. Therefore, you should see a doctor if you have:

Severe pain that will not go away

Blood in your urine

Fever, chills, or signs of infection

Trouble passing urine

Nausea or vomiting that does not stop

Because quick treatment can prevent complications, do not delay seeking help.
