Hi, I am new and feel a bit of a fraud. I have found your forum because have been desperately looking for help to work out what is happening to my body. I have been unwell for nearly a year and have a lot of symptoms of under active thyroid - weight gain, constipation, hair loss, tiredness, muscle pain, heavy periods, to name a few. However, having had several blood test, the only thing that has come back is that my calcium levels are low. My t4 is within normal parameters and because of this I cannot have a t3 test. Can anyone help on how to push for a t3 test or would this not be something I need? Also, does any of this seem familiar and how did you find out about your under active thyroid? Thank you for taking time to read this and I appreciate any help you can offer.
