The 4 types of Kidney stones and their common symptoms

Defined as hard and small mineral deposits that develop inside your kidney, kidney stones are made up of acid salts and minerals. The causes of this disease are not well-defined, although risk factors include drinking very little amounts of water and having a diet rich in sodium, protein and oxalate (chocolate and green leafy foods for example). However, knowing the type of kidney stone you suffer from can help ascertain the cause.

Here are the common types of Kidney stones.

Struvite stones

This type of kidney stone is usually a response to certain kind of infection, such as a urinary tract infection for example. Characterised by rapid growth and a large size, struvite stones can develop without any warning signs.

Calcium stones

These are the most common type and are caused by a diet rich in oxalate. Risk factors for calcium stones include a diet consisting of plenty of nuts, chocolates and certain fruits and vegetables; metabolic disorders, high doses of vitamin d and intestinal bypass surgery, all of which can increase the amounts of calcium or oxalate in your urine, indicating the development of kidney stones.

Cystine stones

Those individuals with a hereditary disorder that causes their kidneys to produce certain amino acids (cystinuria to be precise) in excess are most likely to get cystine stones.
