Quoted message said:I have a brother in law who suffers from awful headaches.
He recently had a brain scan and there were no
abnormalities. His wife told me recently that he doesn't
drink anything other than coke or coffee. Is it possible
his body isn't getting enough fluids (water)?
Anybody got any ideas

There are all sorts of types of headaches. For people who
get headaches often they tend to be grouped as either
migraines, tension or cluster headaches.
Caffeine or caffeine withdrawal is known to be a precipitant
of migraines in some people, but that doesn't mean that will
definitely be the cause in your brother in law's case.
Caffeine based drinks probably don't hydrate the body well
since caffeine is a diuretic and causes increased urinary
output. So it could well be that your brother in law's fluid
intake is not optimum, but it would unlikely be a cause for
headaches if he is otherwise well, but could be.
I suggest you look up the features of tension, cluster and
migraine headaches to decide which sort (if any) your
brother in law falls into. Sometimes things can be done if
specific triggers/types are identified.
