Bilateral adrenal tumors have not been studied for a definite cause and may be related to genetic and endocrine disorders. Most adrenal tumors are benign tumors, and a few are malignant. According to the presence or absence of endocrine function, they are divided into functional adrenal tumors and non-functional adrenal tumors. There is no clear cause for this disease, which may be related to genetics and endocrine disorders. Since the adrenal glands have the function of secreting hydrocorticotropic hormone, glucocorticoid hormone, catecholamine hormone, etc., functional adrenal tumors may lead to water and sodium retention and symptoms such as edema and hypertension. Pheochromocytoma secretes a large amount of catecholamine hormones, leading to panic attacks, hypertension and other symptoms; non-functional adrenal tumors generally only appear when the tumor is large, resulting in lumbar discomfort. It is recommended to actively seek medical advice and follow the doctor’s instructions for examination and treatment.
