Broadcaster Hector Ó hEochagáin revealed on RTÉ Radio 1 that he underwent frightening brain surgery in July to remove a small pituitary tumour, a condition he had monitored for 15 years. Medics in Galway operated because the 6mm TSH-secreting adenoma was altering his daily body functions and vital hormones.
What We Know About Hector Ó hEochagáin’s Surgery
- The TG4 presenter and podcaster had a 6mm TSH-secreting adenoma removed from his pituitary gland by Galway medics in July, after monitoring the growth for 15 years.
- The rare condition, affecting one in two to three million people, was previously managed with injections before it began altering critical daily hormones.
- Ó hEochagáin kept the diagnosis private, sharing it only with his wife and family until first discussing it on The Tommy, Hector and Laurita podcast.
Fifteen Years of Monitoring and a Sudden Change
The condition first entered Ó hEochagáin’s life a decade and a half ago, leading him into the world of endocrinology and specialized medical care. For years, the presenter managed the TSH-secreting adenoma with regular injections.
The situation shifted over the summer when the 6mm growth began affecting his physical regulation. As EVOKE reported, the television star noted that the tumour started “acting the maggot, doing certain things to the body” and altering essential hormones. Because his specific adenoma affects only one in every two to three million people, his medical journey even included participation in a study in Cambridge, UK, according to EVOKE.
The Reality of a First Operation
Facing his first-ever general anaesthetic and operating theatre experience proved daunting for the author and broadcaster. The procedure required specialists to enter through the nose and drill through to the skull to reach the pituitary gland, which he described to The Irish Times as being the size of a grape, with the tumour resting on the back like a piece of sweetcorn.

The pituitary gland governs fundamental human processes, running the thyroid, regulating heart rate and metabolism, and controlling bones and blood. With the surgery successfully completed in July, Ó hEochagáin spent a couple of months recovering quietly in Galway. He later shared the news on The Tommy, Hector and Laurita podcast alongside co-hosts Tommy Tiernan and Laurita Blewitt, subsequently opening up further on RTÉ Radio 1’s Brendan O’Connor Show.
Public Response and Recovery in Galway
The decision to speak publicly about the operation brought an immediate wave of connection with listeners facing similar medical hurdles. According to The Journal, the presenter received messages from across Ireland, the United States, and Australia from individuals whose family members had undergone identical pituitary procedures.
Reflecting on the experience from his home in Galway, Ó hEochagáin emphasized a renewed appreciation for everyday moments, urging people to disconnect from mobile phones, share conversations, and enjoy local football matches. The procedure behind him, the broadcaster returned to public life alongside the launch of his latest book, Irish words for every occasion.
