I've been on 100 mcg levothyroxine now for 8 months gradually increased to this dose my symptoms have started after 2 years to finally calm down less tired less brain fog more energy. However my breasts have nearly doubled in size my dr just laughed when i mentioned this I have put on weight as most people do with this horrible disease but just wondering if this has happened to any else I've gone form a c cup to a ff I hate it 😞could it be the levothyroxine is to strong and causing to much hormone ??? I'd be grateful to know if it has happened to anyone else 😀

    Hello Lyndsey:

    My name is Shelly and I am a nurse in the USA and I have Hashimoto's Thyroid disease.

    In some people LEVO can cause estrogen to go up in the body and also it can change your metabolism so you feel hungry.

    If you have higher levels of estrogen in you the breasts will get bigger. Also the body as we gain weight can store fat there.  Most of the breast is made up of adipose (FAT) tissue, and it can swell like when you are pregnant.

    I would decrease the dose by 25% and see if it helps.  You may want to change to a small dose of LEVO and some T3 Liothyronine (cytomel), so that may be an option.

    Yes, in short the female hormones can get raised while on Thyroid medication. 

    I hope this helps.  Any other questions just ask.

    Shelly

    Hi Lyndsey, Yes, happened to me too and  Shelley thanks for explaining it - I thought it might be breast cancer! Phew, that's a big stressor off my shoulders.

      Hello LAH:

      Breast cancer is silent and causes an orange peel or dimple look on the breast and a nodule that is hard.  It also makes RBC'S (red blood cells) go down and sodium goes down in the blood.

      All of us should get yearly mammogram's.  I do.  Also breast cancer is normally or can be linked to a family gene known as BRCA gene.

      Most of the breast is adipose tissue in a pretty package.  LOL.

      XO, Shelly
