Which condition does NOT relate to calcium deficiency?

Calcium deficiency is primarily associated with conditions that relate to the skeletal system and overall bone health. Rickets, for instance, is a disease characterized by weak or soft bones in children, directly linked to a lack of calcium and vitamin D. Poor teeth can also result from inadequate calcium, as calcium is crucial for maintaining tooth strength and structure.

Anemia, while it can be caused by several deficiencies, is mainly related to a lack of iron or vitamin B12 rather than calcium. This makes goiter, which is related to thyroid hormone production and often involves iodine deficiency, an unrelated condition to calcium levels in the body. As a result, the connection between calcium deficiency and goiter is absent, solidifying its position as the condition that does not relate to calcium deficiency.
