“normal” makes me angry
The ranges for thyroid hormones are insane. TSH often 0.5 - 5.5 does capture 95% of the statistical “normal” range, but that 95% also captures people with real thyroid problems. “Normal” does not mean healthy or optimal. Doctors make this mistake all of the time and also assume that only 5% of a population could have a problem. I have only see a single case where a doctor was reported to ask and be concerned with iodine - which is a dismal state of affairs.
TSH should be near 1.0
T3, fT3, T4, fT4 should be near midrange.
TSH never tells the whole story. Oral body temperatures do that.
fT3 should be tested as it is the only active thyroid hormone.
If fT3 is mid-range and body temperatures are low we need to suspect elevated rT3 blocking fT3 at T3 receptors.
Almost all doctors do not think this way. They are into disease management and if they cannot nail down a disease diagnostic code they really have no idea about what to do other than get you out of the office. Medical systems and insurance also work against health management or optimization as unnecessary medical treatment. If payers other than your self are not involved, you and a doctor can do anything. However, it is really on your shoulders to become knowledgeable and take matters into your own hands. You need to manage your own “health” care and being passive with doctors and/or accepting lab “normal” really is not in your interest.
Is this comforting? “The average increase in body weight in studies was less than 5 pounds (2,25 kg) over 2 years.”
Average increase… there are some who gain a lot of fat with these implants.
I suggest that you consider the merits of an IUD which will allow your hormones and libido to normalize.
Every woman is unique to some degree in her hormone levels, patterns and hormone complications. And women react quite differently, physically, mentally and sexually to birth control hormones. IUD’s do not create significant systemic hormones loads and thus are the least intrusive.
