I'm a breastfeeding mum to a 1 year old. I had a total thyroidectomy over ten years ago and have been on a surpressive dose of levothyroxine since. Since breastfeeding I have been feeling hyperthyroid symptoms. Is there a link between reduced oestrogen levels in breastfeeding and the effect this has on thyroid hormone uptake? My blood levels haven't changed dramatically.
Any advice/experiences appreciated.
