People can experience symptoms of intolerance when they encounter certain ingredients in alcoholic beverages. We publish material that is researched, cited, edited and reviewed by licensed medical professionals.

Hodgkin\u2019s lymphoma, ovarian cancer, breast cancer and other diseases can all cause a sudden onset of alcohol intolerance in those who never before experienced difficulty drinking. The sudden development of alcohol intolerance does not necessarily mean that a new disease is present. However, a person in this situation should still seek medical attention to ensure that a health problem has not recently developed.<\/p>\n
