A common complication of kidney stones is which of the following?

Nausea is a common complication associated with kidney stones primarily due to the intense pain and discomfort that can occur during a kidney stone episode. The presence of kidney stones can cause obstruction in the urinary tract, leading to increased pressure in the kidneys, which in turn can trigger nausea. This response is often related to the body’s efforts to cope with the pain and the stress associated with the condition.

The connection between pain and nausea is well-documented, as the body’s autonomic nervous system can influence feelings of nausea during episodes of severe pain. In addition to the physical pain, psychological factors such as anxiety about the condition can also contribute to feelings of nausea.

Other complications like dehydration can occur with kidney stones, but they are not typically classified as a direct complication arising from the presence of the stones themselves. Similarly, while vomiting and fatigue can occur, they are often secondary responses to pain or the body's overall reaction to the stress of having kidney stones. Nausea is more directly linked as a common result of the discomfort caused by the stones.
