Alcohol intolerance may occur in ME/CFS. It usually develops after the onset of the illness, where the patient was previously able to tolerate alcohol. It may form part of a wider range of allergies and sensitivities that can develop during the course of the illness.
Recovery from CFS/ME is often accompanied by the return of alcohol tolerance.
A 2019 study with Stanford ME/CFS Initiative reported that 66% of subjects meeting the 1994 Fukuda CFS criteria were less able to tolerate alcohol compared to their pre-illness state. This finding replicates those in a 2004 study of patients fulfilling UK criteria for chronic fatigue syndrome referred to a specialist clinic: two-thirds reduced alcohol intake. The most common reasons were increased tiredness after drinking (67%), increased nausea (33%), exacerbated hangovers (23%) and sleep disturbance (24%).
Prevalence[edit | edit source]
- 1995, Katrina Berne, PhD, reported an estimated prevalence of 45-75% for alcohol intolerance (although she notes that this symptom may be underreported and therefore more prevalent than indicated).
- 2001, In a Belgian study, 59.5% of patients meeting the Fukuda criteria and 63.7% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported alcohol intolerance.
- A 2019 study with Stanford ME/CFS Initiative reported that 66% of subjects meeting the Fukuda 1994 CFS criteria were less able to tolerate alcohol compared to their pre-illness state.

Possible causes[edit | edit source]
- Channelopathy has been proposed as a mechanism of the illness which would explain intolerance to alcohol and other drugs.
- Gut fermentation problems
- Alcohol is a depressant of the central nervous system, which tends to be hyper-reactive in people with ME/CFS
- Alcohol is toxic for the liver, and many people with ME/CFS have suboptimal liver function
- Alcohol can interfere with the methylation cycle
- Alcohol is a vasodilator - this will exacerbate vascular symptoms such as neurally mediated hypotension or POTS
Potential treatments[edit | edit source]
If a patient presents with alcohol intolerance, alcohol should be avoided, including that in mouthwashes and herbal tinctures.

chronic fatigue syndrome (CFS) - A controversial term, invented by the U.S. Centers for Disease Control, that generally refers to a collection of symptoms as “fatigue”. There have been multiple attempts to come up with a set of diagnostic criteria to define this term, but few of those diagnostic criteria are currently in use. Previous attempts to define this term include the Fukuda criteria and the Oxford criteria. Some view the term as a useful diagnostic category for people with long-term fatigue of unexplained origin. Others view the term as a derogatory term borne out of animus towards patients. Some view the term as a synonym of myalgic encephalomyelitis, while others view myalgic encephalomyelitis as a distinct disease.
somatic symptom disorder - A psychiatric term to describe an alleged condition whereby a person's thoughts somehow cause physical symptoms. The actual existence of such a condition is highly controversial, due to a lack of scientific evidence. It is related to other psychiatric terms, such as "psychosomatic", "neurasthenia", and "hysteria". Older terms include "somatization", "somatoform disorder", and "conversion disorder". Such terms refer to a scientifically-unsupported theory that claims that a wide range of physical symptoms can be created by the human mind, a theory which has been criticized as "mind over matter" parapsychology, a pseudoscience. Although "Somatic Symptom Disorder" is the term used by DSM-5, the term "Bodily Distress Disorder" has been proposed for ICD-11. (Learn more: www.psychologytoday.com)
