Head injury can damage your pituitary gland, even just a mild concussion. BBC radio's 'Inside Health' suggested there are 500k to 1m people who have pituitary damage without knowing it in the UK today. That's up to one in every sixty of the UK's population. The symptoms will be familiar to most people on this website, I'm sure: weight gain, depression, fatigue, intolerance of heat or cold, infertility, loss of sex drive. This makes me wonder - where are those missing million? Could they be here, on this website?
Am I cynical in thinking that people are 'allowed' to have thyroid deficiency because it's relatively cheap to treat, but that deficiencies in the other pituitary hormones - adrenal deficiency, growth hormone deficiency, sex hormone deficiency - are something the NHS doesn't want to find? It's obvious that most people who post are not getting effective treatment - could it be because they are only being treated for the thyroid part of their illness, and not getting the other hormones they need? If you've ever had a head injury, or cranial radiation, or a stroke, or autoimmune disease - even if these events were many years ago - you could have hypopituitarism and I do urge you to get checked out.
