There are early studies (cell, animal and human) that indicate the following may be slightly more common in individuals with SMA:
- Problems of the pancreas (which can include diabetes)
- High levels of leptin (a hormone which regulates appetite and body weight by reducing feelings of hunger)
- Problems with muscle mitochondria (parts of a cell which produce energy)
It is recommended that everyone with SMA should have the levels of sugar in their blood checked, particularly when unwell.
