Development of new sensitivities
The development of new sensitivities which were not present before the illness or have worsened since is a common occurrence in ME/CFS. Early studies of Long COVID found that some patients developed new allergies including anaphylaxis, and worsening of existing allergies was also found.
Symptom recognition[edit | edit source]
- The International Consensus Criteria lists sensitivities to food, medications, odors or chemicals as an optional criteria for diagnosis, under the section C. Immune, gastro-intestinal and genitourinary Impairments.
- 2018, The Centers for Disease Control and Prevention note ME/CFS patients can have "allergies and sensitivities to foods, odors, chemicals, or noise."
Types of sensitivities[edit | edit source]
Prevalence[edit | edit source]
- In a 2001 Belgian study, 48.5% of patients meeting the Fukuda criteria and 54.8% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported new sensitivities to food or drugs.

anaphylaxis "an often severe and sometimes fatal systemic reaction in a susceptible individual upon exposure to a specific antigen (such as wasp venom or penicillin) after previous sensitization". Typically causes breathing problems, fainting or loss of consciousness, fast heartbeat, itching, and hives. (Learn more: www.nhs.uk)
