Before asking for a hormone panel, there are other labs worth talking about!
One of the biggest misconceptions I hear is that we can simply check a āhormone panelā and it will answer all of your questions.
And unfortunately itās just not that simple!
During perimenopause, estrogen and FSH can fluctuate significantly, which means a single snapshot may be completely ānormalā even when youāre experiencing very real symptoms.
For many womenāespecially over 45 with typical symptomsāperimenopause is primarily a clinical diagnosis based on your age, symptoms and menstrual history.
But hereās what I DONāT want us to do:
Assume every new symptom in your 30s or 40s is automatically perimenopause.
Because several other things can look VERY similar.
Depending on your symptoms and history, I may consider:
𩸠CBC + ferritin/iron studies ā anemia or iron deficiency, especially with heavier periods
š¦ TSH ± free T4 ā thyroid dysfunction can cause fatigue, weight changes, palpitations and menstrual changes
š§ Vitamin B12 ā particularly with fatigue, brain fog, numbness/tingling or risk factors for deficiency
š¬ A1C ± fasting glucose ā screening for prediabetes/diabetes when appropriate
š¤°š¼ Pregnancy test ā yep! If pregnancy is possible, a late or missed period isnāt automatically perimenopause
āļø Vitamin D ā sometimes appropriate depending on symptoms, risk factors and medical history
And this does NOT mean every woman needs every one of these tests.
The point is to have a better conversation than simply:
āCan you check all my hormones?ā
Instead, try:
āIām having new symptoms that I think could be perimenopause. Could we talk about whether anything else needs to be ruled out?ā
šš¼ THAT is a conversation worth having.
And remember: you donāt need an abnormal hormone level to prove that your symptoms are real or deserve treatment.
SAVE this for your next appointmentāand send it to the friend whoās been saying, āI swear something has changed, but all my labs are normal.ā š¤
