Patients with hyperlipidemia should visit the endocrinology department, as hyperlipidemia is a manifestation of lipid metabolism disorder and is classified as a metabolic disease. Therefore, it falls under the purview of the endocrinology department. Moreover, hyperlipidemia is typically divided into secondary and primary types. Many cases of secondary hyperlipidemia are associated with endocrine disorders such as diabetes, hypothyroidism, Cushing's syndrome, and polycystic ovary syndrome, which are primary diseases of the endocrine system that can lead to lipid abnormalities. Therefore, patients with hyperlipidemia should seek treatment in endocrinology to identify the underlying causes of the condition.
