Many women have problems with low energy and fatigue. Although there are many reasons to have fatigue, low thyroid function is often the cause. It’s important to discuss your symptoms with your physician, and to have complete thyroid function testing done. Having test results that are in the “normal” range does not necessarily mean that your thyroid is functioning “optimally”. Many physicians prescribe thyroid medication only if the test results are clearly outside the “normal” range. Thyroid disease, though, can be very subtle, and some women have symptoms of low thyroid function if their test results are at the lower end of the “normal” range. In addition to fatigue, low thyroid function can also cause weight gain, inability to lose weight, hair loss, brittle nails, menstrual cycle irregularity, and infertility. These symptoms must be taken into consideration when determining whether thyroid medication is appropriate for you.
In addition to low thyroid function, there are other causes of fatigue such as a low vitamin D level, anemia (low blood count), and a low ferritin level. Many women have vitamin D deficiency unless they take a vitamin D supplement daily. Anemia often results from heavy menstrual periods if the iron that is lost every month by bleeding is not replenished by an iron-rich diet or an iron supplement.
