Has anyone had a similar experience?
Background: I’m hypothyroid (over 5 years now) and as a consequence of failing to properly convert T4 (increasing Levothyroxine dose > 220 mcg and increasing daily, failed to provide relief) and as local medical practice effectively refused endo referral and passed me on to a (very expensive!) private consultancy, I am now self-medicating using NDT, which has proved a success, restoring me to a `reasonable degree of health and “normal” energy levels.
Other than that, I’m fit and active, with no known health issues save those related to the thyroid condition.
Situation: Last summer I was on holiday with my family on the south coast. On a very hot, sunny day, I was swimming in the sea (at times fully immersed) for about 08-10 minutes, enjoying the water along with many other bathers. I began to get cold, so started to exit, back to the warm beach. As I began to return the 20 m or so to the beach, I increasingly struggled, as my energy just seemed to melt away, very, very rapidly, over just 1-2 minutes.
I ultimately needed help to get out of the water and back to my chair, and was visibly shivering intensely as my core body temperature seemingly plummeted...a paramedic could not get a reading! Because I did not recover fairly immediately, I was taken to A&E, where I warmed up to normal temperature en route. The doctors in A&E assessed me but came up with no firm conclusions save that my hypothyroidism was somehow a factor?
Question: My family are obviously concerned about the prospect of a recurrence, though I should add that we had spent two weeks basically living by the unheated swimming pool in a hotel in the Italian Lakes, only a few weeks prior, (we are all strong swimmers) with absolutely no similar health problems.
So, my question, can anyone relate to this experience and have you got any input as to its possible cause/remedy(ies)?
Thank you
