can anxiety cause dizziness
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.
