Adrenal hyperplasia may be dangerous because it can cause conditions such as primary aldosteronism and congenital adrenocortical hyperplasia. In addition, certain adrenal hyperplasia may not cause abnormal hormone secretion, so it is not dangerous, but it needs to be reviewed regularly. 1. Primary aldosteronism: primary aldosteronism is caused by adrenal hyperplasia, which will lead to high blood pressure with severe hypokalemia, and can be treated with oral spironolactone, eplerenone and other medicines under the guidance of doctors, and surgical removal is feasible when necessary. 2. Congenital adrenocortical hyperplasia: it is an autosomal recessive hereditary disease, and the clinical manifestations depend on different enzyme defects and the degree of defects. If the enzyme is completely deficient, the corresponding hormone secretion is absolutely insufficient, and untimely treatment may lead to death. 3. If there is only adrenal hyperplasia, but without a series of symptoms such as high blood pressure and low blood potassium, treatment is usually not needed. However, regular review is required. Therefore, patients with adrenal hyperplasia should go to regular hospitals in time for standardized treatment under the guidance of doctors.
