Many people notice a significant weight loss as they go through stressful situations. This is the influence of corticotropin, a hormone produced by a tiny gland in the brain when you undergo a stressful situation. Corticotropin urges adrenal glands to produce epinephrine, commonly referred to as adrenalin, which evokes agitated state and suppresses appetite just as well.
19. Addison’s disease (adrenal insufficiency)
Lack of cortisol, a hormone associated with stress, can be just as bad as its excess. Patients with adrenal insufficiency, also known as Addison’s disease, suffer from nausea, dizziness and become exposed to plenty of infections. Rapid weight loss is one of the earliest signs of adrenal insufficiency. Another characteristic symptom is darkened skin, especially in knee and elbow areas.
