Symptoms of Anxiety. Symptoms of Anxiety: Introduction. The symptoms of anxiety are due to the body's reaction to stress called the fright, fight or flight response. This reaction developed in early human evolution as a means to increase alertness and readiness to react to dangerous stressors, such as the threat of a man-eating predator.
But if all three opinions concur, you can feel confident that stress, including anxiety-caused stress, is the cause of this symptom and not some other medical or biological problem. Causes relating to anxiety include: Hyper- and hypoventilation - taking in too much or too little oxygen. Hyper and hypoventilation can change the CO2 levels in the blood, which can cause a myriad of anxiety-like symptoms, such as dizziness. An active stress response - behaving in an apprehensive manner activates the stress response.
