Yes, men can also suffer from Hypothyroidism.
In my case, my thyroid gland was damaged by medication for a non-related disease and it was a known risk.
The first thing to understand about TSH is that the 'range' is a reference range.
Each of us has our own much smaller range that is optimal somewhere within the reference range.
The blood labs use of 'normal' for any result that it within the reference range is misleading and incorrect.
In the real world of patient experience, most of us need a TSH of no greater than around 1 or 1.5 to overcome symptoms.
However, this is only part of the story.
Symptoms are not caused by high or low TSH and may not even be caused by high or low FT4 levels.
Hypothyroid symptoms are cause by insufficient absorption of T3 at a tissue level.
You can have 'in-range' TSH and 'in-range' FT4 and still have hypo symptoms if there is insufficient T3 absorption.
This insufficient T3 absorption at a tissue level can be the result of poor T4 to T3 conversion, and/or a deficiency that reduces T3 absorption.
T4 to T3 conversion can be checked by including FT3 (Free T3) in a blood test.
Unfortunately, there are no tests for measuring T3 absorption at a tissue level, which is why blood tests do not provide all of the information that is needed to diagnose and treat hypothyroidism.
It is also why symptoms should not be ignored or blamed on other so-called 'diseases' such as chronic fatigue syndrome or fibromyalgia, both of which appear to have been invented to explain why people still had hypothyroid symptoms with a 'normal' TSH and/or monotherapy with Levothyroxine.
Poor conversion and poor absorption are mainly caused by vitamin and mineral deficiencies.
Here again, we come back to the misinterpretation of blood test reference ranges.
With Thyroid hormones, vitamins and minerals (and many other things, no doubt), each of us will normally have our own optimum range somewhere within the reference ranges. In the case of vitamins and minerals, it seems that we need to have levels around the middle of the ranges in order to have good conversion and absorption.
Another issue is poor absorption of the replacement hormone medication in the gut, so the replacement hormone does not even make it in to the blood stream, because absorption is being blocked.
This can be caused by not leaving enough time (1 hour, typically) between taking the replacement hormone medication and the consumption of anything other than water.
It can also be caused by some types of medication that are contra-indicated with replacement thyroid hormones and inhibit absorption.
Doctors who believe that TSH and FT4 are the only things that they need to know in order to diagnose and treat hypothyroidism have been brainwashed by the official guidelines.
Unfortunately, these guidelines are inadequate, inaccurate, misleading and only cover about 1/3 of the issues that can be significant.
You can find that specialists in other medical disciplines, such as cardiology and nephrology, recognise the significance of T3 while Endocrinologists and GPs who have been brainwashed by the guidelines, are dismissive of the importance and significance of T3.
It requires a lot of patience and negotiating skills for us patients to overcome this and may patients find that reverting to self-medication is often the only solution to achieve a feeling of well-being.
