Why exactly are they hyperactive when sympathetic stimulation typically inhibits peristalsis and GI activity in general?

Bump... anyone?

if anyone could shed some light on sympathomimetic vs anticholinergic, that would be much appreciated
The hyperactive bowel sounds does not makes sense to me, nor does the excess sweating in sympathomimetic considering this is Ach innervation too (despite being part of sympathetic system)

I think it's to do with the amphetamines also increasing serotonin levels which play a play in GI motility

there are two types of sweat glands - on innervated by acetylcholine at muscarinic receptors and one innervated by noradrenaline. both are under control of the sympathetic nervous system
