Symptoms of anxiety

We will follow this by looking at examples of anxiety disorders.

Physical symptoms of anxiety

When we feel stressed, chemicals are released from a part of the brain called the hypothalamus. These trigger more chemicals from another part of the brain called the pituitary glands, which in turn triggers cortisol to be released from the adrenal glands, located on top of the kidneys. This is known as the hypothalamus – pituitary – adrenal axis or HPAA for short.

The cortisol that is released is responsible for many of the anxiety symptoms commonly experienced, otherwise known as the ‘fight or flight’ response. Whilst this is a normal response to a perceived threat, with anxiety disorders, the ‘fight or flight’ response is overactive. It happens even when there is no real danger.

• Dizziness and feeling lightheaded
• Hot and cold flushes
• Stomach complaints, nausea and vomiting
• Headaches
• Difficulties sleeping
• Easily fatigued
• Loss of appetite
