Can anxiety cause physical symptoms?
Yes. Anxiety can affect your body as well as your thoughts and emotions, and sometimes the physical symptoms are the first thing somebody notices.
A racing or more noticeable heartbeat, dizziness, headaches, nausea, stomach problems, muscle tension, breathlessness, disrupted sleep and feeling unusually tired can all occur alongside anxiety.
Why does anxiety feel so physical?
When you feel anxious or threatened, your body’s stress response can become activated. This can affect your heart rate, breathing, muscles and digestive system, which is why anxiety can sometimes feel like something is physically wrong rather than simply feeling worried.
Those sensations can then create more anxiety. Feeling your heart racing, becoming dizzy or noticing tightness in your body may make you focus more closely on what you are feeling, particularly if you do not know why it is happening.
Many symptoms associated with anxiety can also have other causes. Heart palpitations, for example, can also be linked with exercise, lack of sleep, medication, caffeine and other factors. New, unexplained, persistent or concerning physical symptoms should therefore be discussed with an appropriate healthcare professional.
If anxiety itself has become persistent, is affecting your sleep, making everyday situations harder, interfering with relationships or work, or causing you to avoid things you would normally do, it may also be worth seeking mental health support.
At The Therapy Company, support for anxiety can include counselling, CBT and private psychiatry depending on what you are experiencing and the support that is appropriate.
Appointments are available in Preston, with online appointments available for suitable services.
