Hi
My daughter is being investigated for high prolactin levels. Latest bloods were
FSH (Roche E170) 5
FreeT 4(RocheE170) 12.1 LOW
LH (Roche E170) 11
Prolactin (RocheE170) 778 HIGH (has been as high as 1300)
TSH(RocheE170) 1.5
Symptom: extreme fatigue, low mood, rapid moods swings, menstrual cycle has changed from 28 days to 35-40 days.
Current diagnosis’ : Tourette’s, FND (functional neurological disorder), depression
Current medication: fluoxetine 20mg
Strong family history of thyroid problems - paternal nan, aunt and female cousin, maternal nan and great aunt
I’m aware that fluoxetine can increase prolactin but with her other bloods and symptoms is that a red herring.
Any advice on what could be the cause and what I should be talking to her consultant about (further investigations/treatment etc) please?
Thank you

High prolactin extremely common with autoimmune thyroid disease
For full Thyroid evaluation she needs TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis
In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
