A kidney stone refers to the formation of a hard mass that is composed of crystals that have got separated from the urine. These generally get accumulated within the urinary tract. Normally, urine contains certain chemicals, the function of which is to inhibit the accumulation of such crystals from developing.
However, in some people due to some irregularity these chemicals fail to function properly and hence, stones are resulted. If the crystals happen to be tiny, they will easily be passed out of the body through the urine. Thus, tiny crystals are not a cause of worry.
These chemicals reach the body through the daily food intake and are necessary for the strength of muscles and bones
Rarely, urinary tract infections are also found to cause stones. This type of infection stone is called a struvite. In some people, uric acid stones are also found to occur.
Kidney stones remain inside the body without causing any symptom for a long period. Most often, the first symptom of a kidney stone is severe abdominal pain. The friction caused as the stone moves within the urinary tract causes pain.
In some cases, the stones will be large enough to stop the flow of urine. Typically, a person feels a sharp and cramping pain in the back and lower abdominal sides towards the area of the kidney. Later, the pain advances to the groin. In some people, symptoms such as nausea and vomiting accompany the sharp pain.
In case of larger stones, the pain will get more intense as the muscular wall of the urinary tract will attempt squeezing the stone into the urinary bladder. Traces of blood appear in the urine as part of this ‘push and pull’ process. Burning sensation while passing urine is yet another symptom of kidney stone accumulation
