Facioscapulohumeral muscular dystrophy (FSHD) is one of the most common inherited muscle conditions in adults. It causes muscles to become weaker over time, making everyday activities such as lifting the arms, climbing stairs and walking more difficult. Many people also experience pain, fatigue and a loss of independence. Although researchers know the genetic cause of FSHD, there are currently no treatments that can slow down or stop it.
Recent research suggests that muscle cells in people with FSHD may struggle to produce and use energy efficiently and to repair themselves after damage. This may contribute to the gradual loss of muscle strength.
The research team has found early evidence that metformin, a medicine that has been used to treat type 2 diabetes, may improve the growth and health of muscle cells, including cells from people with FSHD. This needs to be better understood to see if it could potentially be developed as a treatment for FSHD.
