Adrenalin Overproduction Symptoms

Do you now what are adrenalin overproduction symptoms? I understood tachycardia and increased blood pressure as well as weight loss and nervousness. So, what causes these conditions? I can find much information about it and I would like to know what are medical problems associated with adrenalin overproduction. Thank you in advance

Here is what I know. I know only that overproduction of adrenalin causes cancer of the adrenal gland. These types of cancers are rare but when they occur, these tumors may secrete excess amounts of cortisol. The symptoms you might experience are related to those hormones, for instance, an adrenocortical carcinoma, and produces symptoms similar to Cushing's syndrome: high blood pressure, weight gain, excess body hair, osteoporosis and diabetes.
