What are the classic symptoms associated with hypervitaminosis D?

Hypervitaminosis D occurs when there is an excessive accumulation of vitamin D in the body, leading to increased levels of calcium in the blood (hypercalcemia). This condition can produce a variety of symptoms, primarily related to elevated calcium levels.

The classic symptoms associated with hypervitaminosis D include hypercalcemia, which can lead to marked distress. One of the symptoms often seen is polyuria, which is the increased production of urine that occurs as the body tries to excrete excess calcium. Additionally, psych disturbances, such as confusion, lethargy, or more severe alterations in mental status, can also occur due to the effects of high calcium levels on the central nervous system.

Other options contain symptoms that are either too vague or not strongly associated with hypervitaminosis D. For instance, while abdominal pain, diarrhea, and nausea may occur (as related to high calcium), they are not as classic or specific as the symptoms of hypercalcemia and its effects on urine output and mental status. Similarly, fatigue and muscle pain might be encountered but are not as distinctly indicative of hypervitaminosis D.

In summary, the hallmark symptoms of hypervitaminosis D are specifically tied to the physiological impact of high calcium levels, leading
