Information on all the illnesses reported by veterans of the 1990-91 Gulf conflict while still serving is not held centrally, as the Ministry of Defence does not hold records of all medical conditions reported after an individual has left the services. The NHS is responsible for the health care of ex-service personnel but information on diagnoses does not differentiate Gulf veterans. For those Gulf veterans still serving, Defence Medical Services are responsible for providing treatment for all medical conditions. We do not, however, hold diagnostic information specific to the operations on which personnel were deployed.
