Kidney Stones

Kidney Stone treatment in India - Why Do Kidney Stones Form?

Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. This short explains some of the common factors that can lead to their development.

How diet and hydration can play a part

What you eat and drink can influence your risk of forming kidney stones.

• Not enough water. Dehydration makes your urine more concentrated. This allows stone-forming minerals to build up and stick together.
• Too much salt. A high-sodium diet can increase the amount of calcium your kidneys must filter, which may raise the risk of stones forming.
• Certain foods. Diets high in animal protein or oxalate-rich foods like spinach and nuts can contribute to some types of kidney stones.

Underlying health and personal factors

Your general health and medical history can also affect your risk.

• Medical conditions. Digestive diseases, recurrent urinary tract infections, and certain metabolic disorders can increase the chance of developing stones.
• Family history. If a close family member has had kidney stones, you may be more likely to have them as well.
• Obesity. A high body mass index (BMI) is linked to changes in the acid levels of urine, which can lead to stone formation.
• Previous stones. If you have already had one or more kidney stones, you are at an increased risk of forming another.

The exact cause of kidney stones can be complex and depends on the individual. A specialist can determine your specific risk factors after a full evaluation, including a review of your medical reports and any recent imaging.
