Anxiety is a symptom of many medical disorders

Q: I have been told by doctors that my anxiety is all in my head. But I have read that sometimes anxiety can be caused by something else. What are some conditions that can cause anxiety?

A: Anxiety is an emotion in which a person generally experiences tension, and worrisome thoughts. It may be accompanied by physical changes such as an increase in respiratory and heart rates, an elevation in the blood pressure and tremors. Additional symptoms can include muscle tension, headaches, abdominal cramps, nausea, and diarrhoea.

During stressful times it is quite natural to become anxious. However, some individuals may feel anxious day in and day out, for no apparent reason. Such persons are often deemed to be suffering from generalized anxiety disorder when such anxiety persists for six months or more.

In the case of secondary anxiety, the anxiety experienced is not the primary issue, rather it is secondary to another or an underlying medical disorder.

Secondary causes of anxiety need to be considered if any of the following is present:

  • It is recent onset
  • It came on suddenly
  • There is no family history of anxiety or mental disorders
  • There is no identifiable reason for one to be anxious
  • You are more tired and or drowsy than normal
  • There is accompanying disorientation or loss of memory
  • The level of anxiety is very variable
  • The onset of your symptoms began in later life
  • You recently stated a new medication (even supplements)
  • You have other comorbidities
  • There are abnormalities on your physical examination.

Below are listed some of the secondary causes of anxiety:
