This reaction manifests itself by the body's increased production of adrenaline. The body's rapid production of adrenal hormones increases metabolism of proteins, fats, and carbohydrates. The body's muscles tense, and heartbeat and respiration's increase. An individual having the attack is swallowed by the fear of disaster or death. At such times it is impossible to think rationally, and the more one tries, the more difficult it is to become realistic.
Anxiety actually consumes the individual.
Chest pain, dizziness, trembling, chills, nausea, and a distorted perception of time can accompany this disorder. After a few days, these stressors can cause generalized aches, which include muscle spasms, and pain, depression, nightmares, and early waking. Other sensations that may occur include digestive disturbances, which may include the urgency to urinate, and defecate. The unrealistic feelings of tension, and inability to relax consume ones thoughts. Therefore the stressed body is more vulnerable to free radical damage.
