A team from New York Presbyterian hospital is conducting a study about a recent increase in cases involving both excess sweating and kidney stones. Before the team draws a conclusion about the cases, what would the team need?

A. medications that are specifically designed to treat the sickness

B. machines that are built to process blood and reduce symptoms until patients are healthy again

C. data that profile the various patients who report these symptoms

D. proof that the excess sweating is related to the excessive kidney stones

The loss of water via sweating can result in less production of urine. The more one sweat, the less one urinate, this permits the stone-causing substances to settle and bond in the urinary tract and in kidneys.

On the other hand, when a stone moves from the kidneys into the ureter, it can result in an obstruction in the flow of urine, upsurging swelling and pressure inside the kidney and result in the symptoms of kidney stones. The associated signs can involve nausea, sweating, and vomiting.

Thus, the correct answer would be option D, that a proof that the excess sweating is associated with the excessive kidney stones.
