Oftentimes, people who begin to experience severe low back and abdominal pain might be suffering from what are known in the medical profession as renal calculi. In laymen's terms, these are called kidney stones. And the question "How fast can a kidney stone form?" is one of a host of queries almost every calculi sufferer eventually asks. To get the answer, there are a few things that should be understood.
To begin with, a kidney stone can form in either one of the pair of kidneys most humans are born with – one on the left flank, or dorsal aspect near the lower back, and the other on the right. The kidneys themselves are responsible for filtering out waste products and water from the bloodstream. All of these products, and the water that goes with them, ends up as urine to be excreted from our bodies as waste.
According to medical statistics, something like 15 percent of all Americans will experience at least one instance of kidney stone development in their lifetime. In this regard, they're a relatively common medical problem, though the pain they can cause can be quite significant in some cases. Kidney stones can end up forming in the kidney due to a number of factors, dehydration being one of them.
There are numerous different shapes and sizes of these stones. Some may be black or gold in color, though most are brown or yellow. And their individual size can range from a tiny speck all the way up golf ball-sized in extreme cases. Additionally, the rougher in texture they are, the more pain the usually cause. Some stones are absolutely smooth, but that's fairly rare.
As to how fast a kidney stone can form, medical opinion holds that the issue of renal calculi is dependent on a host of risk factors and behaviors in a person. Some may form literally overnight, though they are generally minuscule in size, and some may take months to form until they become palpably pain inducing. Generally, the first indication a patient will have of a renal calculi is when low back pain begins, and then increases in intensity.
