kidney stone travel health tips

Overview

A kidney stone is a hard, pebble-like piece that can form in one or both kidneys. It is made from minerals and salts in your urine. Stones can be tiny or quite large. They can cause pain when they move or block the flow of urine.

Yes, kidney stones are fairly common. They can happen to anyone, but they are most often seen in adults between 30 and 60 years old.

Kidney stones can affect people of all ages. Men are slightly more likely to get them than women. People who don't drink enough fluids, have a family history of stones, or have certain medical conditions are at higher risk. Traveling to warm climates can raise the risk because you may sweat more and drink less water.

Symptoms

Common symptoms

• Severe pain in your side or back, below the ribs
• Pain that spreads to your lower belly or groin
• Pain or burning when you urinate
• Pink, red, or brown urine
• Cloudy or strong-smelling urine
• Feeling sick to your stomach or vomiting
• Needing to urinate more often than usual
• Fever and chills (if there is also an infection)

Symptoms in children

• Tummy (belly) pain that is hard to explain
• Fussiness or crying more than usual
• Vomiting
• Blood in the urine
• Painful urination
• Fever without a clear cause

Symptoms in older adults

• Pain in the side or back that may be less severe than in younger people
• New confusion or unusual sleepiness
• Fever or chills
• Pain or difficulty urinating
• Blood in the urine

Causes

Main causes

• Not drinking enough water, especially when you sweat more (like in hot climates or during long flights)
• Urine that is too concentrated and high in minerals like calcium, oxalate, or uric acid
• Eating a diet that is very high in salt or sugar
• Certain medical conditions that change how your body handles minerals
• A family history of kidney stones

Risk factors

• Dehydration from not drinking enough fluids — the most common trigger, especially when traveling
• Living in or visiting a hot, dry climate
• Eating foods high in oxalate (like spinach, rhubarb, and almonds) without balanced calcium
• Being overweight or having obesity
• Having diabetes, gout, or high blood pressure
• Some digestive diseases or surgeries that affect how you absorb food
• Taking certain medicines (talk to your doctor about your risk)

When to see a doctor

See a doctor urgently if:

• Any symptom in the emergency list above
• Severe pain that comes on suddenly and doesn't go away
• Fever or chills with kidney pain
• Being unable to urinate
• Symptoms while you are far from medical help — get to care as soon as possible

Book a routine appointment if:

• You have had a kidney stone before and want to prevent more
• You have regular urinary symptoms that worry you
• You are not sure if your symptoms could be a stone

Diagnosis

A doctor will ask about your symptoms, do a physical exam, and order tests to look for a stone. They may use imaging to see the stone and check if it is blocking urine flow.

Tests that may be done

• Urine test to look for blood or signs of infection
• Blood test to check kidney function and look for minerals that cause stones
• CT scan or ultrasound to find the stone and measure its size
• Stone analysis — if you catch the stone, the lab can tell you what it is made of

What to expect at your appointment

You may be asked to drink extra fluids and pass urine through a strainer to catch the stone. The doctor may give you advice on pain relief (ask your pharmacist for a suitable product). If a stone is large, you may need to see a specialist for further treatment.

Treatment

Treatment for a kidney stone depends on its size, where it is, and how much pain it causes. Many stones are small enough to pass naturally. Larger stones may need procedures to break them up or remove them.

Self-care at home

• Drink plenty of water every day — keep a bottle with you and refill it often, especially when traveling
• Ask your pharmacist or doctor which over-the-counter pain reliever is safe for you
• Take a warm bath or place a warm, damp cloth on your side or back to help ease discomfort
• Move around gently — walking may help a stone pass
• Strain your urine with a fine mesh or clean cloth to catch the stone so it can be tested
• If you are away from home, find the nearest clinic or emergency service and note their address and phone number

Medical treatments

Doctors may prescribe medicines that help relax the urinary tract and make it easier for a stone to pass. For larger stones, treatments include shock wave therapy (sound waves used to break the stone into smaller pieces), a procedure using a thin scope to remove the stone, or surgery. Your doctor will explain which approach is right for you. No specific drug names or doses are given here — always follow your doctor's advice.

When is surgery considered?

Surgery or a procedure is usually needed when a stone is too large to pass, blocks the flow of urine, causes repeated infections, or triggers severe pain that cannot be controlled.

Living with this condition

If you have kidney stones or have had them before, planning ahead makes traveling easier. Carry a refillable water bottle, avoid long periods without drinking, and pack any medicines you take. It also helps to know the signs of a blockage or infection and to have a plan for getting medical help quickly when you are away from home.

Lifestyle tips

• Drink enough fluid to keep your urine pale yellow — aim smaller, frequent sips rather than waiting until you're thirsty
• On long flights or road trips, take breaks to stretch and use the restroom
• In hot climates, increase your water intake and limit drinks that can dehydrate you, like coffee and alcohol
• Avoid crash diets and very high-salt foods
• Talk to your doctor before any big trip if you are prone to stones

Diet and exercise

Eat a balanced diet with plenty of vegetables, fruits, and whole grains. If your doctor or dietitian advises it, limit foods high in oxalate and reduce salt. Get regular exercise, but avoid becoming dehydrated — for example, taking exercise classes or hiking in hot weather. Carry water with you during any physical activity.

Mental health and emotional wellbeing

Living with kidney stones can be stressful, and worrying about an attack during travel can cause anxiety. It may help to talk to your doctor about your concerns, plan an emergency contact, or speak with a counselor if you feel overwhelmed. You can also reach out to a support group — online or in person — to connect with others who understand.

Prevention

In most cases, yes. Drinking enough water and making some diet changes can reduce your risk of developing new kidney stones. Your doctor may do tests to find the cause and give you a personal prevention plan — this is especially useful if you travel often.

Vaccines

Not applicable

Screening programmes

Not a routine screening test, but if you have had kidney stones, your doctor may recommend repeat imaging or urine tests to watch for new stones.

Complications

If left untreated

• A stone blocking the flow of urine can cause a buildup of pressure and damage your kidney
• An infected stone can lead to a severe kidney infection
• A blocked urinary tract can cause sudden, severe pain that is hard to control
• Long-term blockage can lead to permanent kidney damage or kidney failure

Long-term outlook

With the right care, most people with kidney stones recover well. Many stones pass on their own, and medical procedures are highly effective for larger stones. By staying hydrated and following your doctor's advice, you can lower your risk of future stones and continue to enjoy an active life, including travel.
