How to address Low Thyroid Premenstrual Symptoms

Low Thyroid (Hypothyroid) Premenstrual Symptoms
If a woman has poor thyroid function, such as low grade hypothyroidism (“subclinical hypothyroidism”), then her PMS/PMDD symptoms will often be worse than if she had normal thyroid function. This is not to say that low thyroid function causes PMS/PMDD, but that the underlying PMS/PMDD symptoms will be worse in women with low thyroid function.
While an occasional correlation between PMS/PMDD and low thyroid function has been documented in the medical literature [1], the correlation has also been dismissed in the literature [2]. However, routine thyroid screening should not be ruled out, as hypothyroidism has occasionally been found to co-exist with dysmenorrhea [3].
But even though low thyroid function has not been proven to be a cause PMS / PMDD, it is definitely a hormonal dysfunction that must be tested in all women experiencing PMS/PMDD, based on a consensus of medical research [4-18] One researcher used the term “relative hypothyroidism” as a vulnerability trait (predisposition) to have premenstrual symptoms [12].
So the best answer to questions about low thyroid function and its relationship to PMS/PMDD is to have the thyroid hormones tested. When testing for thyroid function, it is important to measure the actual thyroid hormones (free T3 & free T4), and not just TSH. If there is low thyroid function, consider using ThyroMend™ to improve your thyroid health.
Even if thyroid hormone levels are “in the normal range”, there can still be poor thyroid hormone function that can determined based on analysis if symptoms and risk factors. The Hypothyroid Risk Questionnaire™ can be used to reveal likelihood of hypothyroidism. If there are many symptoms and risks, then the questionnaire can be used to decide if ThyroMend™ should be used – even if lab tests are “normal”.

Consider ThyroMend™ if you there are many symptoms of low thyroid function, which may include fatigue or tired; exhausted; difficulty doing everyday activities; everything takes longer to do; low body temperature; weight gain; cannot lose weight with diet & exercise; difficulty remembering; difficulty concentrating; slow or unclear thinking; difficulty learning something new; feeling depressed; feeling discouraged; moody & irritable; decreased motivation; low sex drive; decreased sexual activity; changes in sleep; outer eyebrow thinning; hair is coarse and dry; skin is coarse, dry or scaly; itchy skin; sensitive to cold, cold intolerance; cold hands & feet; decreased sweating; slow pulse; low blood pressure; dizziness or poor balance; feel lightheaded; less than 1 BM daily; constipation, straining ; fluid retention; puffy hands; puffy feet ; puffy face; bags under eyes; pasty, puffy or pale skin; yellow palms & soles; enlarged tongue; teeth imprints on tongue; thinning eyelashes; recurring infections; nasal congestion; hand & feet numbness; change in voice; joint stiffness & pain; muscle aches; muscle weakness; hearing problems; recurrent headaches.
