The answer

The diaphragm is a thin layer of muscle that sits between your chest and your tummy. It separates your lung cavity from your abdominal cavity.

A raised diaphragm is where the diaphragm is elevated. In this case, your husband has an elevated hemidiaphragm, which is where one half of the diaphragm is raised.

Your GP will be looking for the reasons why this has happened. It could be a problem with the diaphragm itself, or something going on above it or below it.

For example, a raised diaphragm could be caused by:

  • A lung infection
  • Part of one lung collapsing
  • A clot on the lung
  • Fibrosis of the lung – where the lung stiffens (often due to exposure to irritants like dust or an allergy).

Your GP may need to request further investigations or refer your husband to an appropriate specialist to determine a possible underlying cause and how this can best be managed.
