Most people don’t think about their kidneys until something goes wrong. One of the most common kidney conditions is kidney stones, and while they often begin silently, they can quickly cause severe pain and serious complications if left untreated.
The good news is that your body usually gives you warning signs before the condition becomes more serious. Recognizing these symptoms early can help you receive prompt treatment, reduce pain, and protect your kidney health.
Here are seven kidney stone symptoms you should never ignore.
1. Severe Pain in Your Back, Side, or Lower Abdomen
The most recognizable symptom of a kidney stone is sudden, intense pain that starts in the back or side, usually below the ribs. As the stone moves through the urinary tract, the pain may travel toward the lower abdomen or groin. Many people describe kidney stone pain as one of the most severe types of pain they have ever experienced. It often comes in waves and may change in intensity.
2. Blood in Your Urine
If your urine appears pink, red, or brown, it may indicate blood caused by a kidney stone irritating the urinary tract. Sometimes the blood is visible to the naked eye, while in other cases it is detected only through laboratory testing. Either way, blood in the urine should never be ignored.
3. Pain or Burning During Urination
As a kidney stone moves closer to the bladder, passing urine may become painful. A burning sensation while urinating can also occur with urinary tract infections, making medical evaluation important to determine the exact cause.
4. Frequent Urge to Urinate
Do you suddenly feel like you need to urinate every few minutes? Kidney stones can irritate the urinary tract, creating a constant urge to urinate—even when only a small amount of urine is passed.
5. Cloudy or Foul-Smelling Urine
Healthy urine is usually clear and has only a mild odor. Cloudy urine or urine with a strong, unpleasant smell may suggest an infection, which sometimes develops alongside kidney stones. This combination requires prompt medical attention.
6. Nausea and Vomiting
Kidney stone pain doesn’t affect only the urinary system. Because the kidneys and digestive system share nerve pathways, severe kidney pain can trigger nausea and vomiting. Many patients experience these symptoms during painful episodes.
7. Fever and Chills
This is one symptom you should never ignore. If kidney stone symptoms are accompanied by fever, chills, or shaking, it may indicate a urinary tract infection that has spread to the kidneys. This situation can become a medical emergency and requires immediate treatment.
Why Do Kidney Stones Form?
Kidney stones develop when minerals and salts in the urine become concentrated and form crystals.
Common risk factors include:
- Not drinking enough water
- High salt intake
- Diets rich in animal protein
- Obesity
- Family history of kidney stones
- Diabetes
- Recurrent urinary tract infections
- Certain metabolic disorders
Staying well hydrated and maintaining a balanced diet can significantly reduce your risk.
How Are Kidney Stones Diagnosed?
Your doctor may recommend one or more of the following tests:
- Urine examination
- Blood tests
- Ultrasound (USG KUB)
- CT Scan
- X-ray (when appropriate)
These investigations help determine the size, location, and type of kidney stone, allowing doctors to choose the most appropriate treatment.
Treatment Options
Treatment depends on the size and location of the stone.
Small Stones
Small kidney stones often pass naturally with:
- Drinking plenty of water
- Pain-relieving medications
- Medicines that help relax the urinary tract
Larger Stones
Larger stones may require specialized treatment, including:
- Shock Wave Lithotripsy (ESWL)
- Ureteroscopy (URS)
- Percutaneous Nephrolithotomy (PCNL)
- Laser-assisted stone removal in selected cases
Your urologist will recommend the best treatment based on your condition.
Tips to Help Prevent Kidney Stones
Simple lifestyle changes can lower your risk:
- Drink 2.5–3 liters of water daily (unless your doctor advises otherwise).
- Reduce excess salt in your diet.
- Eat a balanced diet rich in fruits and vegetables.
- Maintain a healthy weight.
- Avoid excessive sugary drinks.
- Follow your doctor’s advice if you’ve had kidney stones before.
When Should You See a Doctor?
Seek medical care immediately if you experience:
- Severe or unbearable pain
- Blood in your urine
- Fever or chills
- Persistent vomiting
- Difficulty passing urine
- Pain that does not improve
Early diagnosis can prevent complications such as kidney infection or urinary blockage.
