Listening to Dr Kelly Brogan on the Thyroid Sessions back in 2014 was the first realisation that my thyroid may be a piece of my postpartum psychosis puzzle. Dr Kelly discussed the triangle of psychiatric symptoms, gluten intolerance and thyroid dysfunction and this was the first time I heard a medical doctor discuss postpartum psychosis directly. Women with first episode postpartum psychosis were 19% positive for thyroid antibodies and within 9 months 67% had a higher risk to develop autoimmune hypothyroidism (1). Dr Kelly discussed how postpartum thyroid symptoms can be easily attributed to being a new mum, such as lead limbs, feeling fatigued, super forgetful, mentally disorganised which at 9 months postpartum could be symptoms of Hashimoto’s disease or postpartum thyroiditis. Postpartum issues lead straight to psychiatry, no acknowledgement of the female hormones, not even a test for thyroid function. Dr Kelly says that psychiatric symptoms are usually endocrine related: thyroid or adrenal or blood sugar regulation with insulin or leptin or your sex hormones progesterone or oestrogen. Also, zinc, selenium, magnesium and iodine are key nutrients in thyroid function. To find out more about these psychiatric pretenders I recommend reading A Mind of Your Own.
Typically when you go to your General Practitioner, the thyroid test is limited to blood test TSH, which is a pituitary hormone measure, an indirect measure of thyroid function. To get the full picture of your thyroid free thyroid levels T3 and T4, reverse T3 and thyroid autoantibodies. My GP was reluctant to do further tests as my TSH came back ‘normal’ until I showed him a copy of the research paper (1). Remember there is not one size fits all, you may have symptoms even being in the ‘normal’ range.
The Thyroid Secret is on now and I am looking forward to tuning in to Episode 7: Motherhood Interrupted to discover more about the role of thyroid in the postpartum period (starts on Wednesday 8 March 10am Sydney time).
PS: My test results including my thyroid antibodies came back all good and my GP has noted on my file to check and monitor my thyroid function if and when I fall pregnant.
