Can A Woman Have Kidney Stones?

Yes. Women get kidney stones, and they get them for many of the same reasons men do. In fact, the gap between men and women has been narrowing for decades, and some research suggests the number of women diagnosed with kidney stones has been rising. Anyone who has ever passed one knows the pain does not check your gender at the door.

The short answer is simple: kidney stones are a human problem, not a male one. Roughly 1 in 11 people in the United States will have a kidney stone at some point, and women make up a large share of that group. The more useful question is why women get them, how the symptoms can look different, and what actually helps.

How Common Are Kidney Stones in Women?

Kidney stones are common in women. Historically, men were diagnosed with stones more often than women, but that gap has shrunk. Some studies suggest the rate in women has climbed while the rate in men has stayed fairly steady, though researchers are still working out exactly why.

One factor that gets discussed is body weight. Higher body mass index is linked to a higher risk of stones in both sexes, and rising obesity rates may play a role in the shifting numbers. Diet also matters. So does hydration.

What is clear is that a woman with a kidney stone is not an unusual case. Emergency departments see them regularly. The condition is well studied and well understood, even if the experience of passing a stone is miserable.

Why Do Women Get Kidney Stones?

Kidney stones form when certain minerals and salts in urine become concentrated enough to crystallize. The most common type by far is calcium oxalate. Others include calcium phosphate, uric acid, struvite, and cystine stones, though cystine stones are rare.

Several things raise the odds of forming a stone:

• Not drinking enough water. Concentrated urine gives minerals a chance to clump together.
• Diet high in sodium. Extra salt pushes more calcium into the urine.
• Low calcium intake. This surprises people. Eating too little calcium can actually raise oxalate absorption and increase stone risk.
• Obesity and weight gain. Linked to higher risk in both women and men.
• Certain medical conditions. Including gout, some bowel diseases, and repeated urinary tract infections.
• Some medications and supplements. Including high-dose vitamin C and certain diuretics.
• Family history. Stones tend to run in families.

Women also have some risk factors that are specific to them. Pregnancy raises the risk of stones, partly because of changes in urine chemistry and because a growing uterus can make it harder for urine to drain from the kidney. A history of urinary tract infections is another factor, since some infections can set the stage for struvite stones.

Menopause may also matter. Estrogen appears to influence how the kidneys handle calcium and other minerals, and lower estrogen after menopause has been linked to changes in urine chemistry that could favor stone formation. The research here is still developing, so it is fair to say the picture is not fully settled.

Do Kidney Stone Symptoms Differ in Women?

The core symptoms are largely the same in women and men. The classic sign is severe, cramping pain that starts in the back or side and moves toward the lower abdomen and groin as the stone travels down the ureter. The pain often comes in waves.

Other common symptoms include:

• Blood in the urine, which may look pink, red, or brown
• Nausea and vomiting
• Pain or burning when urinating
• A constant urge to urinate
• Urinating small amounts frequently

There is one place where women’s experience can differ: women are more likely to have urinary tract infections, and a UTI can produce some overlapping symptoms like burning and frequent urination. That overlap can make it harder to tell what is going on. A stone can also block urine flow and lead to an infection behind it, which is a serious situation.

If a woman has fever, chills, or severe pain along with urinary symptoms, that combination needs medical attention quickly. An infected, blocked kidney is a medical emergency, not something to wait out at home.

How Are Kidney Stones Diagnosed in Women?

Diagnosis usually starts with a medical history and a physical exam. A doctor will ask about the pain, how it started, and whether there is any blood in the urine. A urine test can check for blood, infection, and crystals.

Imaging confirms the diagnosis. A non-contrast CT scan of the abdomen and pelvis is the most accurate test and can show the size and location of a stone. Ultrasound is often used instead, especially in pregnant women, because it avoids radiation. Ultrasound is less sensitive for small stones in the ureter, so it may miss some.

Blood tests can check kidney function and look for underlying conditions like high calcium or gout.

If a stone is passed, some doctors ask the patient to collect it so it can be analyzed. Knowing the stone’s composition helps guide prevention. This step is often skipped, but it can be useful, especially for people who form stones repeatedly.

How Are Kidney Stones Treated?

Treatment depends on the size and location of the stone and on the severity of symptoms. Many small stones pass on their own with fluids and pain control. Doctors often recommend drinking enough water to produce a good amount of urine, and using pain relievers as needed.

For stones that are too large to pass, or that cause severe pain, blockage, or infection, procedures may be needed:

• Extracorporeal shock wave lithotripsy (ESWL). Sound waves break the stone into smaller pieces that can pass in urine.
• Ureteroscopy. A thin scope is passed through the urinary tract to find and remove or break up the stone.
• Percutaneous nephrolithotomy. A surgical procedure for large or complex stones.

Which option is best depends on the stone and the patient. A doctor will weigh factors like stone size, location, and whether there is any infection. There is no single “right” choice for everyone.

One point worth knowing: a medication called tamsulosin is sometimes used to help small stones pass. The evidence on how well it works is mixed, and it is not a guaranteed shortcut. Some clinicians recommend it, some do not.

What Can Women Do to Lower Their Risk?

Prevention is where the real leverage is. The single most important step is drinking enough water. Staying well hydrated keeps urine dilute, which makes it harder for minerals to crystallize.

Diet changes matter too. Reducing sodium helps because salt drives calcium into the urine. Getting enough calcium from food, rather than cutting it out, is generally recommended for most stone formers. Oxalate-rich foods like spinach, rhubarb, and nuts do not need to be avoided entirely by everyone, but people who form calcium oxalate stones may be advised to moderate them.

Other steps that may help:

• Limiting animal protein, which can raise uric acid and lower citrate in urine
• Eating enough fruits and vegetables, which can raise urine citrate, a natural stone inhibitor
• Maintaining a healthy body weight
• Talking to a doctor before taking high-dose vitamin C or calcium supplements

For women who form stones repeatedly, a doctor may prescribe medications. Thiazide diuretics can reduce calcium in the urine. Allopurinol can lower uric acid. Potassium citrate can raise urine citrate. These are not first-line for everyone, and they are typically used after a stone analysis and metabolic workup.

Pregnant women with stones need special care. Treatment options are more limited because of the fetus, and the approach is usually coordinated between obstetrics and urology. No clinical guidelines exist for every scenario in pregnancy, so decisions are made case by case.

When Should a Woman See a Doctor?

Anyone with symptoms that could be a kidney stone should get medical attention. That includes severe flank or back pain, blood in the urine, or pain that comes in waves. Do not try to tough it out.

Go to the emergency department right away if there is fever, chills, vomiting that will not stop, or pain so severe it cannot be controlled at home. These can signal an infection or a complete blockage, both of which need urgent treatment.

Women sometimes delay care because they assume the pain is something else, like a UTI or menstrual cramps. That delay can be costly. If the pain is severe and one-sided, get it checked.
