Fatigue
Fatigue in MS is not just an ordinary tiredness, like you
might get at the end of a hard day's work. It can be described as a feeling of
mental or physical exhaustion. And one
of the annoying things is that despite how much you sleep, you wake up feeling
as tired as you did when you went to sleep.
It is also described as an overwhelming sense of tiredness
with no obvious cause, you may feel extremely tired after very little activity,
your limbs might feel heavy, and it becomes harder to grasp things or to write.
And other symptoms might get worse alongside the fatigue, like like
difficulties with balance, vision or concentration.
Fatigue affects people in different ways, and it may change
from week to week, day to day, or hour to hour.
All kinds of activities can be affected by fatigue: from
going to work, to going to the pub, cooking a meal or playing with your
children. Balancing these activities can become a daily issue when you have got
limited reserves of energy.
Because it is hidden, people with
MS may find that those around them don't understand fatigue and its impact.
Why does fatigue
occur in MS?
The cause of fatigue in MS
remains unknown. However, the likely causes are a structural abnormality in the
brain caused by demyelination and axonal loss, a product of the immune activity
in the brain itself, problems of hormone production from the pituitary gland in
the brain, or due to problems with control of the heart or chemical changes in
the muscles.
