Consistently low cortisol can point toward adrenal insufficiency (Addison's disease or a pituitary problem) and cause fatigue, low blood pressure, and weight loss. Because levels vary so much throughout the day and in response to stress, single results are often followed up with more specific dynamic testing (like an ACTH stimulation test) when a disorder is suspected.
