Adrenal nodules do not need attention in diet. Adrenal nodules are usually nonfunctional nodules. Abdominal CT and lung CT showed nodules in bilateral adrenal glands or unilateral adrenal glands. Without hypertension, hypokalemia and hypercortisolism, Cushing's syndrome often suggests that adrenal nodules are nonfunctional. At this time, the diet is normal and the exercise is normal. However, if the patient's adrenal nodules are functional, such as hypercortisolism, this situation is rare, but it is true that if Cushing's syndrome occurs, the diet should be low in salt and fat because of hypertension and hyperglycemia. If adrenal nodules secrete low potassium due to the increase of total aldosterone level and blood pressure rises, then vegetables and potassium-rich foods should be eaten in moderation, but attention to this functional nodule in diet is related to its symptoms.
