Kidney Stones in Women: Signs, Prevention & Your Action Plan

Kidney stones are more common than many women realize. While they have historically been more frequent in men, rates in women have been steadily rising. Understanding the signs, causes, prevention strategies, and when to act can make a significant difference in your health and comfort.

This guide explains kidney stones in clear, practical terms—without minimizing the seriousness of the condition.

What Are Kidney Stones?

Kidney stones are hard deposits made of minerals and salts that form inside the kidneys. They develop when urine becomes concentrated, allowing minerals such as calcium, oxalate, or uric acid to crystallize and stick together.

Stones can range in size from a grain of sand to a golf ball. Small stones may pass on their own. Larger ones can block the urinary tract and cause significant pain or complications.

Why Kidney Stones Matter for Women

Women may experience kidney stones differently than men. Hormonal factors, pregnancy, urinary tract infections (UTIs), and certain metabolic conditions can influence risk.

In women, kidney stones can sometimes be mistaken for:

• Urinary tract infections
• Pelvic pain
• Menstrual cramps
• Ovarian cyst pain
• Gastrointestinal problems

Because symptoms can overlap, proper evaluation is important.

Common Signs and Symptoms of Kidney Stones

Symptoms often begin suddenly and can range from mild to severe.

Most common signs:

• Sharp pain in the back or side (often below the ribs)
• Pain that moves to the lower abdomen or groin
• Pain that comes in waves and varies in intensity
• Burning or pain during urination
• Frequent urge to urinate
• Pink, red, or brown urine (blood in urine)
• Cloudy or foul-smelling urine
• Nausea and vomiting

Warning signs that require urgent medical care:

• Fever and chills (may indicate infection)
• Severe, unrelenting pain
• Difficulty passing urine
• Vomiting that prevents you from keeping fluids down

A kidney stone combined with infection can become life-threatening if untreated. If you experience fever and severe pain together, seek immediate medical care.

What Causes Kidney Stones in Women?

Kidney stones form when there is an imbalance in substances in the urine. Several factors increase risk:

1. Dehydration

Not drinking enough fluids is one of the biggest risk factors. Concentrated urine allows crystals to form more easily.

2. Diet

Diets high in:

• Sodium (salt)
• Animal protein
• Oxalate-rich foods (like spinach, nuts, chocolate)

can increase risk in susceptible individuals.

3. Obesity

Higher body weight is associated with increased risk of kidney stones.

4. Hormonal Changes

Hormonal shifts during pregnancy or menopause may affect stone formation.

5. Recurrent UTIs

Certain infections can lead to struvite stones, which are more common in women.

6. Family History

If close relatives have had kidney stones, your risk increases.

7. Medical Conditions

Conditions like hyperparathyroidism, gout, diabetes, and digestive disorders can increase risk.

How Are Kidney Stones Diagnosed?

If kidney stones are suspected, a doctor may recommend:

• Urine testing (to check for blood, crystals, infection)
• Blood tests (to assess kidney function and mineral levels)
• Imaging tests such as CT scan or ultrasound
• Stone analysis (if passed)

If you're experiencing symptoms and want to better understand whether they could be related to kidney stones, a free AI-powered assessment for Nephrolithiasis (Kidney Stones) can help you identify what might be happening before your appointment.

This does not replace medical care, but it can help you prepare for a conversation with your doctor.

Treatment Options for Kidney Stones

Treatment depends on the size, type, and location of the stone.

Small Stones (Often Managed at Home)

• Drinking plenty of water
• Pain relievers (as prescribed)
• Medications to relax the ureter and help pass the stone

Most small stones pass within a few days to a few weeks.

Larger Stones (May Require Medical Intervention)

If a stone is too large or causes complications, treatments may include:

• Shock wave lithotripsy (breaks stones into smaller pieces)
• Ureteroscopy (removal with a small scope)
• Percutaneous nephrolithotomy (surgical removal for very large stones)

Your doctor will recommend the safest and most effective option based on your specific case.

Prevention: Your Action Plan

If you've had one kidney stone, your risk of another increases. The good news is that prevention is often possible.

1. Drink More Fluids

This is the single most important step.

• Aim for enough fluids to produce clear or pale yellow urine.
• Most women need about 2–3 liters of fluid daily (unless otherwise directed by a doctor).
• Spread fluids throughout the day.

2. Reduce Sodium Intake

High salt intake increases calcium in urine.

• Limit processed foods.
• Avoid adding extra salt at the table.
• Aim for less than 2,300 mg of sodium per day (or lower if advised).

3. Maintain Normal Calcium Intake

This surprises many women: do not drastically reduce calcium unless advised by your doctor.

Dietary calcium can actually help prevent certain kidney stones by binding oxalate in the gut.

4. Moderate Animal Protein

Large amounts of red meat, poultry, and seafood can increase uric acid levels.

• Choose balanced portions.
• Incorporate plant-based protein sources when possible.

5. Manage Weight

Healthy weight management lowers risk and improves overall kidney health.

6. Address Recurrent UTIs Promptly

Because infection-related stones are more common in women, treating urinary tract infections early is important.

Special Considerations: Kidney Stones During Pregnancy

Kidney stones during pregnancy are uncommon but possible. Symptoms can mimic labor pain or UTIs.

If you are pregnant and experience:

• Severe side pain
• Fever
• Painful urination
• Blood in urine

Seek immediate medical evaluation. Early treatment protects both mother and baby.

When to Speak to a Doctor

You should speak to a doctor if you:

• Have severe or recurring pain
• Notice blood in your urine
• Develop fever or chills
• Have persistent nausea or vomiting
• Have a history of kidney stones and new symptoms
• Have only one kidney
• Are pregnant and experiencing symptoms

Even if symptoms feel manageable, proper diagnosis helps prevent complications and recurrence.

Kidney stones can sometimes cause kidney damage, infection, or obstruction if untreated. Do not ignore severe symptoms.

The Bottom Line

Kidney stones in women are increasingly common—but they are manageable and often preventable.

Key takeaways:

• Stay well hydrated.
• Watch sodium intake.
• Maintain balanced nutrition.
• Seek medical evaluation for concerning symptoms.
• Don't ignore severe pain or fever.

While kidney stones can be extremely painful, most cases are treatable, and many are preventable with practical lifestyle adjustments.

If you're unsure whether your symptoms could be kidney stones, consider using a free online symptom checker for Nephrolithiasis (Kidney Stones) to help clarify your symptoms before speaking to a qualified healthcare professional.

Most importantly, if you think your condition could be serious or life-threatening, seek medical care immediately. Your kidneys are vital organs—protecting them is worth prompt attention and informed action.
