As someone who was diagnosed with a ‘borderline underactive thyroid’, I always wince at the phrase.


The photo on the left below is from 2015, when I was incredibly ill from ‘only borderline hypothyroidism’, as the doctor kept telling me. You can clearly see that I was not well. I was pale, had huge bags under my eyes and a puffy face.

The photo on the right is two years later, on thyroid hormone replacement.

They refused to treat me for my failing thyroid gland, being destroyed by my own immune system, and dismissed my concerns of feeling overwhelmingly fatigued, weak and unfit. At the end of the day on which this photo was taken, after walking around Edinburgh, I collapsed at the hotel, passing out from pure exhaustion. It took a good hour or so for me to come back around. It was really frightening.

A week later, the doctor eventually agreed to trial me on thyroid hormone replacement and agreed I had autoimmune hypothyroidism now worthy of treatment. Because he let it get that bad. My TSH level still remained ‘borderline’ or ‘subclinical’ yet my symptoms were not ‘borderline’ at all!

‘Borderline’ or ‘Subclinical’ hypothyroidism is a term I am really not keen on, personally. To me, your thyroid hormone levels are either optimal or not.

If they’re not optimal they can cause symptoms and affect your quality of life, so ‘borderline’ levels are no excuse to not treat someone. They are no excuse to withhold crucial medication or imply someone is a hypochondriac. Every person is individual, so we should be treated as such and this includes those with ‘only borderline’ results who have mounting, debilitating symptoms.

Some people will and do feel awful with ‘only borderline’ hypothyroidism.

I lost years of my life to thyroid symptoms ruling it, due to doctors dismissing me because they went on inaccurate testing and outdated, wide ranges, above my symptoms (many patients lose many years) until it was so late for me that the medication they did eventually give me made no difference whatsoever. My body was in too poor a state to make use of the T4-only Levothyroxine. I eventually figured out I needed an NDT medication which did help.

As of January 2022, the NICE Guidance states to only consider thyroid hormone replacement medication if TSH is greater than 10 on two separate blood tests, at least 3 months apart. [1]

My TSH was at a 9, with thyroid peroxidase antibodies raging on at >1300 and symptoms debilitating every part of my life. I was barely remaining in work, I was bed bound most days by the fatigue and I had next to no quality of life. I can’t believe we are still going by such a wide range and ignoring the importance of Free T3, Free T4 and thyroid antibodies too.

If your doctor has said you are borderline or subclinically hypothyroid and is withholding treatment, despite your quality of life suffering, I am sorry.

Please consider seeing another doctor who will pay more attention to your symptoms and not just TSH alone.

You should also have a retest of any borderline/subclinical TSH, Free T3 or Free T4 readings to see if they have gotten better or worse. They can occasionally get better, but for many, they get progressively worse. If you wish to order these yourself, please find a link for those in the UK here and a worldwide link here.

Achieving optimal thyroid levels are crucial when recovering your health from poor thyroid function. ‘In range’ is often not enough to remove symptoms. Please see more information on optimal thyroid levels here.

  1. I was left untreated for years due to not being bad enough for treatment, one night I had a sivare migraine took painkillers it done nothing. Since being on medication they dont get to crawling around the house bad weight has started moving up and down going to keep increasing dose till everything works for me.

  2. I found out recently in 2009 my doctor knew I was hypothyroid but did nothing about it. Nothing was done until 2013 after I had my first child and my levels went mad. I just wish I’d looked into it all more when I first got my symptoms. Even now I am still fighting to get my optimal mess and start to feel better. Your blog helps me so much. Thank you for your great work xx

    1. I’m so sorry to hear that you were left for so many years without proper treatment and attention. It’s never too late to start researching and correcting your levels though. Thank you for your lovely comment x
