10 Underactive Thyroid Symptoms
Reviewed: Dr. Gromatzky
Symptom #7: Weakness
With an underactive thyroid gland, metabolism is generally very slow, and this can cause the body to switch to an alternative energy source. One of these alternatives is catabolism. Catabolism is a process where the body begins to break down muscle and other tissues for the energy that it needs.
With the muscles gradually being broken down for energy, they gradually become weaker. Not only can this lead to a loss in energy, but it can also cause the muscles to ache and it can become quite painful. The lost muscle can be regained when the underlying condition is successfully treated.
