Low estrogen or thyroid?

My wife has symptoms that could be low estrogen or a thyroid issue. Her symptoms are thinning hair, fatigue,fast heart rate from time to time and tired most times. We just had a baby and she is nursing however, she’s had the symptoms before we got pregnant. Can her doctor check the thyroid and estrogen levels even while she is nursing the baby? I was told that the labs can come back abnormal because she is nursing.
I forgot to mention her thyroid levels always come back normal.


  • I would ask your wife’s doctor for a thyroid test, but it is important to know that many people with borderline hypothyroidism are symptomatic but have blood tests may show thyroid hormone levels (T3 and T4) that are slightly low or even within the normal range, or just a slightly elevated TSH.

    Thinning hair is very common after giving birth hair since during pregnancy hair goes into a resting phases and about 6 months after birth that hair that normally would have been shed throughout the 9 month pregnancy is shed in a short period so it feels like you are losing a lot of hair. Your wife’s other symptoms seem fairly normal for a new mother, however since you mentioned that these symptoms were present before the pregnancy I would make an appointment with your doctor just to be sure.

    The majority of people with hypothyroidism have Hashimoto’s disease, which is an autoimmune condition that causes destruction of the thyroid gland over time. As this destruction progresses, the thyroid gland becomes less and less able to produce enough hormones to meet metabolic needs. This is reflected in an increase in thyroid-stimulating hormone (TSH). The thyroid gland produces two hormones, triiodothyronine (T3) and thyroixine (T4).

    Common symptoms of hypothyroidism include fatigue, weight gain, dry hair/skin, brittle nails, easy bruising, cold intolerance, constipation, low libido, headache, joint aching, and slow heart rate.

    If you have mild or borderline hypothyroidism, which is quite common, then taking supplements that help support the body’s production of thyroid hormone may be helpful. Guggul is a supplement that increases production of thyroid hormone (T3). Many nutrients are required to produce thyroid hormone such as vitamins C, E, A and the B-vitamins. Selenium is required for the conversion of T4 to T3. Ashwaganda is an herbal product that also helps boost thyroid function.

    For many people with moderate to severe hypothyroidism thyroid hormone medication is often required. There are several different types of thyroid medications such as the synthetic forms of thyroid hormone (Synthroid and Eltroxin), which provide the body with T4. There is also Cytomel, which provides the body with active T3 however it needs to be taken three times daily. Lastly there is natural thyroid hormone, which can be made at a compounding pharmacy.

    Sounds like a thyroid issue, surely her doctor would be a better choice to answer this question than random strangers.
