Kidney stone prevention tips

Overview

Kidney stones are hard, pebble-like deposits that form inside your kidneys when certain substances in your urine become too concentrated. They can cause severe pain when they move through your urinary tract.

Yes, kidney stones affect about 1 in 10 people at some point in their lives, and rates are rising worldwide.

Anyone can get kidney stones, but they are most common in adults aged 30-60, especially men. People with a family history of stones, certain medical conditions, or who don't drink enough fluids are at higher risk.

Symptoms

Common symptoms

• Severe pain in the side or back, below the ribs, that may come in waves
• Pain that spreads to the lower belly or groin
• Pain on urination or a persistent need to urinate
• Pink, red, or brown urine (blood in urine)
• Nausea and vomiting

Symptoms in children

• Pain in the belly or side (children may not describe it clearly)
• Blood in their urine
• Frequent urinary tract infections
• Vomiting or fussiness

Symptoms in older adults

• Vague abdominal or back pain that might be mistaken for other conditions
• Confusion or lethargy if a stone causes a blockage or infection
• Less specific pain, sometimes just overall discomfort

Causes

Main causes

• Not drinking enough water, leading to concentrated urine
• High levels of calcium, oxalate, or uric acid in the urine
• Certain medical conditions like gout, inflammatory bowel disease, or repeated urinary tract infections

Risk factors

• Family or personal history of kidney stones
• Obesity or a diet high in salt, sugar, and animal protein
• Certain medications or supplements (always discuss with your doctor)
• Dehydration from living in hot climates, not drinking enough, or losing fluids through sweating or illness

When to see a doctor

See a doctor urgently if:

• If you have severe pain that doesn't go away or gets worse
• If you feel feverish or have chills along with stone symptoms
• If you cannot urinate at all

Book a routine appointment if:

• If you have mild, intermittent pain that you suspect might be from stones
• If you notice small amounts of blood in your urine
• After passing a stone, to have it analyzed and discuss prevention

Diagnosis

Doctors use a combination of your history, physical exam, and tests to diagnose kidney stones.

Tests that may be done

• Urine tests to check for blood, infection, and stone-forming substances
• Blood tests to assess kidney function and calcium or uric acid levels
• Imaging tests like CT scan, ultrasound, or X-ray to see the size, shape, and location of stones

What to expect at your appointment

Your doctor will ask about your symptoms and medical history. You may be asked to collect urine for 24 hours to measure how much stone-forming material you excrete. Imaging is quick and painless, though you may need to drink contrast dye.

Treatment

Treatment depends on the stone's size, location, and what it is made of. Small stones are often managed with fluids and pain relief, while larger stones may need medical procedures.

Self-care at home

• Drink 8-12 cups (2-3 liters) of water daily to help flush out small stones
• Take over-the-counter pain relievers as advised by your doctor or pharmacist
• Stay active and move around; gentle activity may help a stone pass

Medical treatments

Your doctor may prescribe medication to help relax the ureter (the tube from kidney to bladder) to ease stone passage. Other treatments include using sound waves to break stones (lithotripsy) or a scope to remove them. All options are discussed with your healthcare provider.

When is surgery considered?

Surgery may be needed if the stone is too large to pass, causes a blockage, leads to infection, or does not respond to other treatments. Modern techniques are minimally invasive and have short recovery times.

Living with this condition

After a stone passes or is treated, you can return to normal activities. The key is to adopt habits that prevent new stones.

Lifestyle tips

• Drink plenty of water throughout the day – enough to produce clear or light yellow urine
• Reduce salt intake (limit processed foods and added salt at the table)
• Eat a balanced diet with plenty of fruits and vegetables, but limit foods high in oxalate (like spinach, rhubarb, nuts) if your doctor advises

Diet and exercise

Aim for a diet rich in calcium from food (not supplements) because dietary calcium can actually help prevent stones. Avoid high-dose vitamin C supplements. Regular exercise and maintaining a healthy weight reduce your risk.

Mental health and emotional wellbeing

Dealing with recurring stones can be stressful and frustrating. It's normal to feel anxious about another episode. Talk to your doctor about a prevention plan to help you feel more in control.

Prevention

Yes, in most cases you can reduce your risk of forming new kidney stones with lifestyle changes. The most important step is drinking enough water to keep urine dilute. Your doctor can give personalized advice based on the type of stone you had.

Complications

If left untreated

• Obstruction of urine flow, leading to kidney swelling (hydronephrosis) and kidney damage
• Urinary tract infections that can spread to the kidney or blood (sepsis)
• Recurring stones that cause chronic pain and repeated treatments

Long-term outlook

With proper prevention, most people can avoid future kidney stones. Even if you do have a stone, modern treatments are highly effective and safe. Following your doctor's advice on diet and fluids can keep you stone-free for years.
