Kidney stones – Symptoms & causes

July 8, 2026

Few conditions are as memorable or as painful as passing a kidney stone. I've had many patients describe kidney stone pain as one of the most intense forms of pain they've ever experienced. Yet long before a stone causes severe discomfort, the body may provide subtle clues that something isn't quite right.

As a Naturopathic Doctor practicing in Ontario for nearly 20 years, I view kidney stones as more than an isolated event. They are often a sign that changes have occurred in the body's chemistry, hydration status, metabolism, or urinary system. Understanding why a stone formed can be just as important as managing the episode itself. 

Whether you've experienced kidney stones before or are concerned about your risk, understanding the symptoms of kidney stones and the factors that contribute to their development can help you make informed decisions about your health.

What Are Kidney Stones?

Kidney stones are hard deposits of minerals and salts that form within the kidneys. Normally, minerals dissolved in the urine remain in balance and pass out of the body without difficulty. However, when certain substances become highly concentrated, crystals can begin to form. Over time, these crystals may combine and grow into stones of varying sizes. Some kidney stones remain small and pass unnoticed, while others become large enough to block part of the urinary tract, leading to significant pain and other symptoms.

 

What Causes Kidney Stones?

One of the most common questions patients ask is: What causes kidney stones?

There is rarely a single explanation. Several factors may increase the likelihood of stone formation, including:

  • Inadequate fluid intake
  • Family history of kidney stones
  • Diet and nutritional factors
  • Certain metabolic conditions
  • Obesity
  • Diabetes
  • Recurrent urinary tract infections
  • Some medications
  • Digestive disorders that affect nutrient absorption
  • Certain medical conditions that alter mineral balance

These kidney stone causes often interact with one another rather than occurring independently.

What Causes Kidney Stones in Women?

Many women wonder whether there are unique risk factors for developing kidney stones.

What causes kidney stones in women? Although the basic process of stone formation is similar for everyone, several factors may increase risk in women, including:

  • Hormonal changes throughout life
  • Pregnancy-related changes in urinary function
  • Recurrent urinary tract infections
  • Certain metabolic conditions
  • Family history
  • Dietary and hydration patterns

While kidney stones have traditionally been more common in men, the number of women affected has increased over recent decades.

 

What Are the Symptoms of Kidney Stones?

The symptoms of kidney stones depend largely on the size and location of the stone. Small stones may pass without causing noticeable symptoms. Larger stones or stones that obstruct urine flow often require a urine test to help identify the underlying cause and guide appropriate treatment.

Common kidney stone symptoms include:

  • Severe pain in the side or back
  • Pain that moves toward the lower abdomen or groin
  • Blood in the urine
  • Frequent urination
  • Burning during urination
  • Nausea
  • Vomiting
  • Difficulty finding a comfortable position
  • Cloudy or foul-smelling urine
  • Fever or chills if an infection is present

The intensity of symptoms often changes as the stone moves through the urinary tract.

What Do Kidney Stones Feel Like?

One of the defining features of kidney stone pain is that it often comes in waves. Rather than remaining constant, the pain may intensify and ease repeatedly as the muscles surrounding the ureter contract.

Patients commonly describe the pain as:

  • Sharp
  • Cramping
  • Severe
  • Stabbing
  • Colicky
  • One of the worst pains they've experienced

The pain usually begins in the back or side before radiating toward the lower abdomen or groin. Because kidney stone pain can resemble appendicitis, gallbladder disease, ovarian conditions, or gastrointestinal problems, proper medical evaluation is important.

 

Signs of Kidney Stones That Shouldn't Be Ignored

Some signs of kidney stones require prompt medical assessment.

Seek urgent medical attention if kidney stone symptoms occur alongside:

  • Fever
  • Chills
  • Persistent vomiting
  • Inability to pass urine
  • Severe uncontrolled pain
  • Significant blood in the urine
  • Symptoms affecting only one functioning kidney

These may indicate infection or urinary obstruction requiring immediate care

Kidney Stones Symptoms in Women

Although the underlying condition is the same, kidney stones symptoms in women may occasionally be mistaken for other conditions involving the reproductive or digestive systems.

Some women experience:

  • Lower abdominal pain
  • Pelvic discomfort
  • Groin pain
  • Pain that resembles menstrual cramps
  • Urinary urgency
  • Painful urination

Because these symptoms overlap with urinary tract infections, ovarian cysts, or gynecological conditions, a thorough assessment is often needed to determine the underlying cause. Recognizing kidney stone symptoms in women early can help ensure timely diagnosis and appropriate medical evaluation.

Understanding Why Kidney Stones Develop

One kidney stone doesn't necessarily mean another will occur. For many individuals, a stone represents an opportunity to better understand their overall kidney health.

Stone formation may reflect changes involving:

  • Hydration
  • Urine concentration
  • Mineral metabolism
  • Digestive health
  • Kidney function
  • Hormonal influences
  • Metabolic health

Looking beyond the stone itself often provides valuable insight into why it formed.


The Naturopathic Approach to Kidney Health

As licensed primary care health professionals in Ontario, Naturopathic Doctors are trained to assess common medical conditions, perform physical examinations, recommend appropriate laboratory investigations where indicated, and recognize situations requiring medical referral or collaborative care. When someone experiences kidney stones, our focus extends beyond simply confirming the diagnosis.

We also ask an important question: Why did this kidney stone develop?

A comprehensive assessment considers hydration habits, nutrition, metabolic health, kidney function, digestive health, medications, family history, cardiovascular risk factors, and other contributors that may influence stone formation.  By identifying the underlying factors contributing to stone development, we can help patients better understand both their kidney health and their overall health.

 

When Should You Seek Medical Evaluation?

Although very small kidney stones may pass naturally, some situations require prompt medical assessment. 

You should seek medical evaluation if you experience:

  • Severe kidney stone pain
  • Persistent vomiting
  • Fever or chills
  • Blood in the urine
  • Difficulty passing urine
  • Recurrent kidney stone symptoms
  • Symptoms lasting more than a short period

Early evaluation helps identify complications and determine the most appropriate next steps.

What is the main cause of kidney stones?

The main cause is concentrated urine, often from not drinking enough fluids. This allows minerals such as calcium, oxalate, and uric acid to crystallize and form stones.

What are five symptoms of kidney stones?

Common symptoms include severe side or back pain, blood in the urine, painful urination, frequent urination, and nausea or vomiting. Cloudy or foul-smelling urine may also occur.

What are 10 foods that can contribute to kidney stones?

Risk depends on the stone type, but foods commonly limited include spinach, rhubarb, beets, nuts, chocolate, wheat bran, processed meats, salty snacks, fast food, and excessive red meat. Do not eliminate dietary calcium without medical advice, as normal calcium intake may help prevent calcium-oxalate stones.

What are the first signs of kidney disease?

Early kidney disease often causes no noticeable symptoms and may only be detected through blood and urine tests. As it progresses, signs can include swelling, fatigue, changes in urination, nausea, itching, or difficulty concentrating.

How can you flush kidney stones quickly?

There is no guaranteed way to flush a kidney stone quickly. Small stones may pass with adequate fluids and doctor-recommended pain relief, while medication such as an alpha-blocker may sometimes help; larger or obstructing stones may require a procedure.


The Bottom Line

Kidney stones are a common condition that can cause significant pain, but they also provide important clues about your overall health. Recognizing the signs of kidney stones, understanding the symptoms of kidney stones, and identifying possible kidney stone causes are important first steps toward protecting long-term kidney health. As a Naturopathic Doctor with nearly two decades of experience providing primary care in Ontario, I believe one of the most valuable parts of healthcare is helping patients understand why health conditions develop—not simply recognizing that they exist.  If you've experienced kidney stone symptoms, recurrent stones, or have concerns about your kidney health, a comprehensive assessment can help identify contributing factors, support informed healthcare decisions, and provide a clearer picture of your overall health.
