Five Reasons for the Muscles Weakness

Today we want to speak about the causes of the unexplained muscle weakness.

Cause #1 Inactive Lifestyle

 It’s not surprising that if you don’t use your muscles for an extended period of time, they lose their ability to work hard. It happens because the fibers (within the muscles) are partially replaced with fat cells. Yes, all left fibers are still active, but there aren’t enough of them, and they can’t contract effectively. As a result, you get your muscles wasting – they become more floppy and less chunky. Some things which are easy to do with the usual state of muscles will be much harder to repeat when the muscles have lost their fit.

Cause #2 Aging

Our muscles are in their best form in our 20s and 30s; unfortunately, no one can avoid aging and its natural consequences. Muscles lose its strength and bulk and become weaker. It is not surprisable that the older we become, the more time it takes to recover from muscle and tendon injuries.

Cause #3 Infections

Most cases of the temporary muscle fatigue are caused by the infections and illnesses. Depending on the severeness of the muscle inflammation, the weakness can last a quite a while and even result in chronic fatigue syndrome. This syndrome can also be a result of any disease with generalized temperature and muscle inflammation, such as:


  1.    Influenza (flu)
  2.    Epstein-Barr virus (glandular fever)
  3.    HIV
  4.    Lyme disease
  5.    Hepatitis C
  6.    Tuberculosis (TB)
  7.    Malaria
  8.    Syphilis
  9.    Polio
