Our kidneys filter all manner of impurities from our blood, helping to keep it clean and healthy. Some of these include certain minerals that we no longer need, and these are filtered out of our blood and into our urine. As this process is happening, urine is being created in our kidneys before it is then passed onto our bladder.

This is not usually a problem as the liquid, containing the minerals, easily makes its way to the bladder. If these minerals are present in higher than usual concentrations, however, then they can begin to crystalize, forming solid lumps. When this happens they are known as kidneys stones. They are usually harmless, but they can be very uncomfortable.

1. Calcium Stones

In the majority of cases, kidney stones will be made largely from calcium. These can be broken down further into two different types, which are calcium oxalate stones and calcium phosphate stones. Both of these tend to form in different ways.

Oxalate is made in our livers, while it is also present in many of the foods that we eat. Certain factors can cause the levels of oxalate rise in some people, and this can result in calcium oxalate stones forming. Calcium phosphate stones tend to be found in people who have certain medical conditions that affect the pH balance of the blood.
