How do you get a suppressed or minus TSH

[dylansmum]

Just read a post on here, stating that a suppressed or minus TSH is a good place to be with

underactive thyroid. How do you achieve this?x

Dylansmum, by increasing dose of thyroid meds. It isn't good to target a TSH level, one should only take as much medication as is required to relieve symptoms. Most people will feel well with TSH just above or below 1.0 but some will need it lower, or even suppressed to feel well. Others are more comfortable with TSH 1-2 and will feel overmedicated with it lower.

Just for clarity, there is no such thing as a negative TSH. Not quite sure why there are references to minus TSH results but they might be to do with how results are presented. For example, very low TSH could be reported as <0.04 but people are misinterpreting the "less than symbol" <. Or it could say TSH - 0.03 where it is really a hyphen.

dylansmum... In theory, the TSH (thyroid stimlating hormone) number will measure how much or how often the body is 'asking' for more thyroid hormone. It is very common for folks who take NDT especially to have a very, very low TSH number. When the body's needs for thyroid are being met by thyroid supplementation, it follows that it won't be 'asking' for more thyroid hormone.

I hope there is a special corner of hell reserved for whomever invented the TSH test. In years past, before it's invention, doctors routinely prescribed and treated underactive thyroid by symptoms.... how one felt, heart rate and body temps.
