Mild adrenal hyperplasia requires only dynamic review if there is no significant function; if there is significant function, surgery needs to be given to treat it. Adrenal hyperplasia is relatively common in clinical practice, and the need for treatment after hyperplasia depends on whether the hyperplastic tissue has hyperfunctional manifestations, such as whether it manifests as Cushing’s syndrome, primary aldosteronism, and pheochromocytoma. Cushing’s syndrome can cause full-moon face, buffalo back, and elevated blood sugar; primary aldosteronism can cause elevated blood pressure with hypokalemia; and pheochromocytoma can cause elevated blood pressure and increased heart rate. Therefore, if mild adrenal hyperplasia is accompanied by the above-mentioned concomitant diseases, it is necessary to give surgical treatment at this time; if there is no concomitant disease, it is only necessary to review dynamically.
