Everything You Should Know About Kidney Stones 

Kidney stones or nephrolithiasis is a common health problem in the United States. Read on to find out what kidney stones are, why they appear, how to prevent them, and how to treat them. 

What are kidney stones?

A kidney stone is a solid mass of tiny crystals that forms in one or both of your kidneys when the levels of certain minerals in your urine are high. Another name for it is nephrolithiasis.

Kidney stones can have different sizes, colors, and shapes. They can be as small as a grain of sand or as large as a golf ball.1

The best way to prevent kidney stones is to stay hydrated – drink at least 2 to 3 liters of fluids per day. You should also avoid eating too much salt.2

Also, depending on the type of kidney stones you have, your doctor may suggest you cut down on some foods or give you medicines to prevent future kidney stones.2

How do you treat kidney stones?

Your physician will suggest a treatment based on the stone’s location, size, and type. As we discussed, small stones may not require treatment. Your doctor will probably recommend that you drink plenty of water and try to eliminate it on your own.3

Larger stones may block your urinary tract and cause a lot of pain. Other possible symptoms are bleeding, nausea, and dehydration. In this case, kidney stones can be removed through:3

After these procedures, some care will still be needed, so following your doctor's recommendations is vital.3
