An adrenal test taken a few months ago indicated moderately low cortisol output throughout the day, however my symptoms have been relatively bad. I wake up groggy and tired, get hypoglycemic reactions after a high protein breakfast, cannot exercise, I have rapidly gained weight and my cognition is impaired. Recently I took a 5mg dose of Cortef in the morning. I reacted badly, and it definitely aggravated a lot of my adrenal fatigue symptoms. I noticed the effect almost immediately. I upped the dose to 10mg with no success. It also makes me bloated and very sleepy, and induces blurry vision, head pressure, breathing difficulties etc. I'm not sure if these are symptoms of adversely high cortisol. Does my body need more cortisol? I'm scared to increase the dose and experience more adverse, debilitating symptoms. I'm self-navigating and it's puzzling why my adrenals are not responding to cortisol therapy. I've attempted different natural treatments from vitamin B5, vitamin c, glandulars and licorice root with no success.
