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.

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)
