What If We Had It All Wrong?!
I shared this recently on socials but for those of us that don't hang around that 'hood I am sharing again here because it is just too important. While we're busy updating our knowledge regarding reproductive health for women (soooo many huge headlines of...
Health is in the Eye of the Beholder
Just last week the sickest patient I've encountered this year (& for perhaps some time) asked me, if I ever see really sick people. This 60 something-year-old farmer has a great sense of humour, so I immediately thought he was joking but as soon as I looked up...

More Histamine Intolerance? Really?! 🤐
I can barely bring myself to write the word given how overused it has been of late 🤐🙄😯😕🙃 But I gotta say something! If we have found ourselves currently in a place where every second (or indeed single!) patient has a 'histamine issue' then I am afraid that it is we,...

Ever Met A Set Of Thyroid Results You Didn’t Like?
