Kidney stones are hard mineral and salt deposits that form inside the kidneys. These crystalline structures develop when there is an imbalance in the urine’s composition—either too much of certain minerals or too little fluid. Kidney Stones Treatment in Dubai is sought after due to the rising number of people affected by this painful condition.
The Role of Diet in Kidney Stone Development
High Oxalate Foods and Their Impact
What adults consume daily plays a pivotal role in the formation of kidney stones. Diets rich in oxalate—commonly found in foods like spinach, beets, nuts, and chocolate—can increase the risk. When consumed in large amounts, oxalate binds with calcium in the urine, forming crystals that may grow into stones.
Animal Protein Consumption
Red meats and other animal-based proteins like poultry, fish, and eggs can lead to higher uric acid levels in the body. Uric acid stones can form when levels rise significantly, especially in individuals who do not hydrate enough or maintain a balanced diet.

Digestive Disorders and Absorption Problems
Conditions such as Crohn’s disease, ulcerative colitis, or those requiring gastric bypass surgery can affect nutrient absorption. These digestive issues may lead to increased calcium or oxalate absorption, altering urine composition and encouraging the formation of stones.
Recurrent Urinary Tract Infections (UTIs)
Frequent UTIs are associated with struvite stones, which form due to certain bacterial infections that make urine less acidic. Women are especially vulnerable to these types of stones due to anatomical differences and recurring infections.
Sedentary Lifestyle and Lack of Physical Activity
A sedentary lifestyle can contribute to bone loss, which increases calcium levels in the urine. Additionally, reduced physical activity may also be associated with slower metabolism and reduced kidney function, which are contributing factors to stone formation.
Obesity and Metabolic Changes
Being overweight or obese can alter urine acidity and composition, increasing the risk of stones. People with obesity often experience higher levels of uric acid and lower urine pH, both of which are conducive to stone development.
Genetic and Hereditary Factors
Family History of Kidney Stones
Genetics play a key role in many adult kidney stone cases. If a close relative has suffered from kidney stones, the likelihood of developing them increases. This is because genetic traits can influence how a person metabolizes minerals or handles fluid balance.
Inherited Disorders Affecting Urine Chemistry
Some people inherit rare conditions like cystinuria, which causes the kidneys to excrete too much of the amino acid cystine. Excess cystine in the urine forms stones that are hard to dissolve and may recur frequently if not managed.
Types of Kidney Stones in Adults
Calcium Oxalate Stones
These are the most common type and result from high levels of calcium and oxalate in the urine. They form in acidic environments and are usually dense and hard.
Uric Acid Stones
Often found in adults with diets rich in purines (found in red meats and seafood), these stones develop in persistently acidic urine. They are more common in men than women.
Struvite Stones
Linked to infections, these stones grow quickly and can become quite large. They are more frequent in women due to the higher incidence of UTIs.
Cystine Stones
These are rare but typically occur in people with a hereditary disorder that causes cystine to leak into the urine. They can recur often and are difficult to manage without ongoing treatment.
Conclusion
Kidney stones in adults are caused by a combination of dietary habits, lifestyle choices, medical conditions, and genetic factors. Understanding what contributes to their formation is the first step toward prevention and better management. While the pain and discomfort associated with kidney stones can be intense, recognizing early warning signs and making targeted lifestyle changes can reduce their occurrence. Kidney Stones Treatment provides various solutions that align with modern healthcare trends and personalized care strategies.
