It starts as a dull ache in the lower back. Then the pain intensifies — suddenly, sharply, moving from the back around the side and down toward the abdomen. For anyone who has experienced it, kidney stone pain is one of the most intense and memorable physical experiences of their life.
Pakistan has one of the highest rates of kidney stone disease in South Asia. Urologists in Islamabad and other major cities report that kidney stones are among the most common reasons patients present at urology clinics — and the numbers are growing year on year.
The extraordinary thing about kidney stones is that in the majority of cases, they are preventable. And the single most effective, most evidence-backed preventive measure costs almost nothing and requires no prescription, no special diet, and no medical procedure.
It is simply drinking enough of the right water every single day.
What Are Kidney Stones and Why Does Pakistan Have So Many?
Kidney stones are hard deposits of minerals and salts that form inside the kidneys when urine becomes too concentrated. When the concentration of certain minerals — primarily calcium oxalate, uric acid, struvite, or cystine — exceeds the kidney’s ability to keep them dissolved, they crystallise and gradually form stones.
Pakistan’s high kidney stone prevalence is driven by several factors that are specific to the country’s climate, diet, and lifestyle:
Climate and dehydration: Pakistan’s hot climate, particularly in summer, causes significant daily fluid loss through sweat. Many Pakistanis consistently drink less water than their bodies need in these conditions — leading to chronically concentrated urine that creates ideal stone-forming conditions.
Diet: Pakistani cuisine is rich in spinach, tomatoes, nuts, and meat — all high in oxalates and purines that contribute to stone formation. Combined with high salt intake, which increases calcium excretion in urine, the dietary risk is significant.
Vitamin D: Pakistan has high rates of both vitamin D deficiency and vitamin D supplementation — both extremes can affect calcium metabolism and stone risk.
Awareness gap: Many Pakistanis do not connect their water intake with kidney health until after their first stone — by which point the habit has already caused damage.
The Science of Water and Kidney Stone Prevention
The relationship between water intake and kidney stone prevention is one of the best-established findings in urology. Multiple large-scale studies conducted over decades consistently show the same thing: people who drink more water have substantially lower rates of kidney stones.
The mechanism is simple. When you drink enough water, urine volume increases and becomes more dilute. Minerals that would otherwise concentrate and crystallise are kept dissolved and flushed out of the kidneys before they can form stones.
A landmark study in the New England Journal of Medicine found that increasing daily water intake to produce at least 2 litres of urine per day reduced the rate of kidney stone recurrence by 50% compared to a control group. This is a more significant protective effect than most pharmaceutical interventions available for kidney stones.
For Pakistani adults who regularly drink less than 2 litres of water per day during summer — which represents a large proportion of the population — simply drinking the recommended amount of water consistently is the most powerful kidney stone prevention available.
The Counterintuitive Truth About Calcium and Kidney Stones
Here is something that surprises many patients when their doctor explains it: drinking calcium-rich water does not increase kidney stone risk. In fact, the opposite is true.
The most common type of kidney stone — calcium oxalate stones, which account for approximately 80% of all kidney stones — forms when oxalate from food is absorbed into the bloodstream and eventually concentrated in urine.
Calcium in drinking water and food binds to oxalate in the digestive system before it can be absorbed into the blood. This binding happens in the gut — preventing oxalate from entering the bloodstream and eventually the kidneys where it would otherwise form stones.
Research consistently shows that people who consume adequate dietary calcium — including from drinking water — have lower rates of calcium oxalate kidney stones than people with low calcium intake. The old medical advice to reduce calcium intake for kidney stone prevention has been reversed by the evidence — adequate calcium intake is now recognised as protective.
This makes calcium-containing mineral water directly beneficial for kidney stone prevention — the calcium content helps neutralise the oxalate from Pakistani dietary staples like spinach, daal, and tomatoes before it can reach the kidneys.
How Much Water Do You Need to Prevent Kidney Stones in Pakistan?
Pakistani urologists generally recommend producing at least 2 to 2.5 litres of urine per day as a kidney stone prevention target. Since a significant proportion of fluid intake is lost through sweat, breathing, and metabolic processes, achieving this urine output requires drinking considerably more.
In Pakistan’s climate:
Winter months: 2.5 to 3 litres of water per day Summer months: 3.5 to 4 litres per day If working outdoors in heat: 4 to 5 litres per day
A practical self-monitoring method: check your urine colour. Pale yellow or nearly clear urine indicates good hydration. Dark yellow or amber means you need to drink more. This simple daily check takes 2 seconds and gives you immediate feedback on whether your water intake is adequate.
Why Mineral Water Is Particularly Beneficial for Kidney Stone Prevention
Not all water is equally effective for kidney stone prevention. Here is what the research shows about different water types:
Plain filtered or distilled water: Provides hydration volume but no minerals. Missing the calcium that protects against oxalate absorption.
Bicarbonate-rich mineral water: Particularly beneficial for uric acid stone prevention. Bicarbonates alkalinise urine, which helps dissolve uric acid crystals before they form stones. Dew Drops Fresh contains 80 mg/l of bicarbonates — a significant protective level.
Calcium-containing mineral water: As explained above, the calcium content directly protects against calcium oxalate stone formation by binding oxalate in the gut.
Magnesium-containing mineral water: Magnesium inhibits the crystallisation of calcium oxalate in urine, providing an additional layer of protection.
Dew Drops Fresh mineral water contains all three of these protective components — calcium, bicarbonates, and magnesium — making it a better daily water choice for kidney stone prevention than plain filtered water.
Practical Daily Habits for Kidney Stone Prevention in Pakistan
Beyond simply drinking more water, these habits specifically target kidney stone risk:
Drink water before bed: Urine is most concentrated during sleep when you are not drinking. A glass of water before sleeping reduces this nighttime concentration risk.
Drink water first thing in the morning: After 7 to 8 hours without fluid, morning urine is the most concentrated of the day. Drinking 2 glasses of water immediately after waking dilutes this concentration quickly.
Limit salt: High salt intake directly increases calcium excretion in urine, raising stone risk. Reducing added salt — particularly in cooking — has a measurable impact on stone formation risk.
Reduce high-oxalate foods or pair them with calcium: Spinach, nuts, chocolate, and tea are high in oxalate. Pairing these foods with calcium — either from dairy or from calcium-containing mineral water — helps bind the oxalate in the gut rather than letting it enter the bloodstream.
Stay hydrated through Ramadan: The combination of fasting and heat during summer Ramadan months creates significant kidney stone risk. Drinking the full recommended water intake between iftar and sehri — prioritising mineral water — is particularly important for anyone with a history of kidney stones.
