The Lourdes Medical Association was first formed in 1972, by a group of doctors who regularly went to Lourdes and felt a need for an organisation to provide support and encouragement. A letter suggesting the need for such a group was sent to all the Bishops of England, Wales and Scotland, with a variety of responses from the supportive to the dismissive. Undeterred, the first meeting was organised in 1975 and the the LMA, at that time an organisation only for doctors, was born. Initial founding members included Dr Laurie Burn, Dr. Bozena Laskiewicz, Dr Felicity Knight and Dr Pat Crosby. Dr Knight's brother Fr. Michael Knight, was for many years the chaplain to the group.
As a group they were determined to be influential as advocates of a good standard of care for those sick travelling to Lourdes, and the organisation flourished, with yearly meetings held in Birmingham. New committee members succeeded the founders, who almost all retained an active interest well after their retirement from clinical medicine and from pilgrimages. The 40th anniversary meeting was held in Glasgow in 2015, and was attended by a large number of past and current members.
The Lourdes Nursing Association was founded separately by nurses caring for the sick on pilgrimage, and the two organisations began to hold some joint meetings in the early 2010s. Modern medical care is increasingly delivered by a joint clinical team of doctors and nurses working together, and in recognition of this, in 2015 discussions began regarding a possible merger of the two organisations, The merger was agreed in 2016, and the British Lourdes Medical Association as it is known today, came into being.
