Thank you for taking the time to answer. Hubby has now been to doctor and looks likely he may be suffering from gastritis. Potentially linked to stress and with alcohol and high fat/spicy foods as as trigger f or symptoms. More tests next week then hopefully medication to help.
Beer ingredients like preservatives, sulfur dioxide as well as histamine could be the trigger. The epithelial lining is a protective covering of the stomach. Intake of too much alcohol damages this lining resulting in inflammation. This triggers stomach pain and cramps. The damage to this lining also causes medical complications.
If you can relate it to alcohol and it isn't a part of your lifestyle it's probably better to just avoid it. If he has problems with his stomach and digestion maybe you could try some probiotics, like yogurt with active cultures. Some people have the good bacteria wiped out of their system by a round of antibiotics and have trouble getting their normal gut flora back to normal. Some don't have the Antibiotics for a reason, they just don't have a good ratio of good flora to bad. If you have a health food store nearby, they usually have some probiotic supplements around, but don't buy the least expensive as they usually are devoid of active bacteria.
Hope it helps!
