Who might have alcohol intolerance?

Whether such therapy can be used in the long term remains to be determined. An individual’s normal ability to tolerate drinking may change over time and as their use of alcohol waxes and wanes. Allergies develop as a result of the immune system mistaking a harmless substance as a dangerous threat, resulting in an overly severe reaction.

A condition called alcohol-induced liver disease can develop in people who have had their gallbladders removed.

However, severe alcohol reactions are misdiagnosed as allergies in some cases when the cause is Hodgkin’s Lymphoma – lymph nodes cancer.
