Can Females Get Kidney Stones?

Yes—females absolutely can get kidney stones. In fact, the number of women who develop them has risen over the past several decades, and some research suggests the gap between men and women is narrowing. Kidney stones are not a “male” problem, and anyone who has ever passed one will tell you the pain does not check your gender first.

Here is the part that surprises many people. For years, kidney stones were roughly two to three times more common in men. That pattern is shifting. Studies looking at emergency department visits and stone diagnoses have found rising rates in women, particularly younger women. Doctors are not entirely sure why, but diet, obesity, and possibly differences in how women are evaluated and diagnosed all seem to play a role.

Can Females Get Kidney Stones?

Females get kidney stones at nearly the same rate as males in some age groups. A kidney stone is a hard, crystal-like mass that forms in the kidney when certain substances in urine become concentrated enough to clump together. The most common type is calcium oxalate, followed by calcium phosphate, uric acid, struvite, and cystine stones.

Nothing about being female protects the kidneys from this process. If anything, some female-specific factors can raise risk. Urinary tract infections, which are more common in women, are linked to struvite stones. Pregnancy changes how the urinary tract works and can make stone formation more likely. And some women develop stones after menopause, when shifts in estrogen and other hormones may affect how the body handles calcium and other minerals.

The takeaway is simple. If you have flank pain, blood in your urine, or pain that comes in waves and radiates toward the groin, a kidney stone belongs on the list of possible causes regardless of your sex.

Why Are Kidney Stones Becoming More Common in Women?

Stone rates are rising in women, and no single factor explains it. Researchers point to several overlapping changes in how people live and eat.

Obesity is one of the strongest links. Higher body weight is associated with changes in urine chemistry that favor stone formation, including higher levels of calcium, oxalate, and uric acid in urine. As obesity rates have climbed in women, so have stone rates.

Diet matters too. Diets high in sodium, added sugar, and processed foods—and low in water—create the conditions stones need. Sodium increases calcium in the urine, and calcium in the urine is a building block for the most common stones.

There is also a practical angle. Women may be more likely than men to seek care for symptoms, which means more stones get diagnosed and counted. That does not mean the rise is only about detection, but it is part of the picture and worth acknowledging honestly.

What Causes Kidney Stones in Women?

The causes are the same basic chemistry in everyone, but a few factors hit women harder or more often.

• Urinary tract infections. Women get UTIs more frequently than men. Certain bacteria produce an enzyme that makes urine less acidic and can lead to struvite stones, which grow fast and can become large.
• Pregnancy. Pregnancy slows the flow of urine and causes the ureters to widen, which can set the stage for stones. Stones during pregnancy are uncommon but not rare, and they need careful management.
• Low fluid intake. Not drinking enough water is one of the most common and most fixable causes in anyone.
• Diet high in sodium and oxalate. Spinach, rhubarb, nuts, and chocolate are high-oxalate foods. They are not “bad,” but in people prone to stones, they can matter.
• Family history and genetics. A parent or sibling with stones raises your risk.
• Certain medical conditions. Gout, diabetes, high blood pressure, and some intestinal diseases raise risk.
• Some medications and supplements. High-dose vitamin C, certain diuretics, and some other drugs can increase stone risk in some people.

One point worth stating plainly: for most people, eating calcium-rich foods does not cause stones. In fact, getting calcium from food alongside meals can lower oxalate absorption and may reduce stone risk. The old advice to cut dairy to prevent stones has largely been reversed.

What Are the Symptoms of Kidney Stones?

Symptoms are the same in women and men. The classic one is severe pain in the side or back, often just below the ribs, that comes in waves. It may radiate toward the lower belly or groin as the stone moves.

Other common signs include:

• Blood in the urine, which may look pink, red, or brown
• Pain or burning when urinating
• Needing to urinate often or urgently
• Nausea and vomiting
• Cloudy or foul-smelling urine, which can point to infection

Some stones cause no symptoms at all and are found by accident on imaging done for another reason. Others pass without much drama. It varies widely by stone size and location.

Get medical care right away if you have severe pain you cannot control, fever, chills, or vomiting. A stone plus a fever can mean a serious infection behind the blockage, and that is a medical emergency.

How Are Kidney Stones Diagnosed and Treated?

Diagnosis usually starts with a urine test to look for blood and signs of infection, plus blood tests to check kidney function and mineral levels. Imaging confirms the stone. A non-contrast CT scan is the most accurate test and is widely used, though ultrasound is often preferred in pregnancy and in some other situations to avoid radiation.

Treatment depends on the size of the stone and how much trouble it is causing.

Small stones often pass on their own. Doctors may recommend drinking plenty of water and using pain relief. Some patients are given a medication that relaxes the ureter to help a stone move along, though this does not work for every stone or every person.

Larger stones, or stones that block urine flow or cause infection, usually need a procedure. Options include shock wave lithotripsy, which uses sound waves to break the stone into smaller pieces, and ureteroscopy, in which a thin scope is passed through the urinary tract to remove or break up the stone. A procedure called percutaneous nephrolithotomy is used for very large stones.

For women who are pregnant, treatment decisions are more careful. The goal is to manage pain and infection while protecting both mother and baby, and the approach is tailored case by case.

How Can Women Lower Their Risk of Kidney Stones?

Prevention comes down to urine chemistry, and a few habits move the needle for most people.

Drink more water. This is the single most effective step for most people who form stones. The goal is to produce enough urine that it stays pale and dilute. Some clinicians advise aiming for roughly 2 to 2.5 liters of urine output per day, but the right amount varies by person, climate, and activity level, so ask your doctor what fits you.

Watch your sodium. Cutting salt lowers calcium in the urine. Most of the sodium in a typical American diet comes from processed and restaurant food, not the salt shaker.

Get calcium from food, not from cutting it out. Pairing calcium-rich foods with meals can help bind oxalate in the gut before it reaches the kidneys.

Limit high-oxalate foods only if your doctor advises it. For most stone formers, restricting oxalate across the board is not necessary and can make eating harder than it needs to be.

Go easy on high-dose vitamin C supplements. Very high doses can raise oxalate in the urine in some people.

Eat less animal protein if you form uric acid stones. Large amounts of meat can raise uric acid and lower a protective substance in urine called citrate.

If you keep forming stones, ask about a 24-hour urine test. It measures the specific substances in your urine and can guide a more targeted plan. This is common clinical practice and can be genuinely useful, though how much it changes outcomes varies from person to person.

Do Women Get Different Types of Stones Than Men?

Broadly, the types overlap, but the mix differs somewhat. Calcium oxalate stones are the most common in both sexes. Women tend to have a higher share of calcium phosphate and struvite stones compared with men, and struvite is closely tied to urinary tract infections.

Uric acid stones are more common in men and in people with gout, obesity, or a diet heavy in animal protein. Cystine stones are rare in everyone and stem from an inherited condition.

Knowing your stone type matters because it changes prevention. A struvite stone points toward infection control. A uric acid stone points toward diet and sometimes medication to raise urine pH. A calcium oxalate stone points toward fluid, sodium, and oxalate balance. If you have passed a stone, ask your doctor to analyze it.
