Hello --
There are a number of potential connections between chronic
constipation and intolerance for alcohol. I guess the real challenge is finding the underlying cause of the
constipation, which is chronic, although much improved.
The connection between this and the intolerance for alcohol could be either secondary (
constipation alters the metabolism of ingested substances and could cause your live to be forced to accept more alcohol per serving than normal) or it could be a shared connection with the underlying cause. Then again it may be coincidental. I doubt this, however, even though most causes of chronic
constipation are fairly benign (changes in diet, exercise routine, too-low fiber diet, dehydration, taking certain supplements -- iron and magnesium come to mind -- and especially taking narcotic painkillers). Others are more troublesome (nerve problems in the GI tract causing gastroparesis, irritable bowel syndrome,
diabetes or
hypothyroidism, either of which should have been ruled out by now).
Diabetes, in particular, can cause both gastric paralysis and intolerance for alcohol.
While it's impossible to determine the relationship -- and causes -- from here, the combination of factors do warrant further study, perhaps by a GI specialist.
I hope this is helpful. Good luck to you and please follow up with us here as needed.
