Signs of a Under-Functioning Thyroid

Hypothyroidism, characterized by low thyroid hormone (T4) levels and elevated thyroid stimulating hormone (TSH) levels, is more prevalent in women and can significantly impact fertility and pregnancy. Subclinical hypothyroidism, where TSH is elevated but T4 remains normal, may manifest without noticeable symptoms.

Some common signs and symptoms that your thyroid may not be under-functioning include:

  • Menstrual irregularities and bleeding problems
  • Constipation
  • Cold intolerance
  • Carpal tunnel syndrome
  • Decreased exercise tolerance
  • Fatigue
  • Depressed mood
  • Mental slowness
  • Poor memory
  • Water retention
  • Swelling around the eyes
  • Slowed reflexes
  • Hypertension
  • Anemia
  • Elevated cholesterol
  • Cystic ovaries
  • Infertility or miscarriage


Hypothyroidism is typically diagnosed through routine blood work, and the primary treatment consists of synthetic T4 medication administered daily. While this conventional approach is effective for many individuals, some may still experience symptoms despite normal blood test results. In such cases, alternative therapeutic approaches may be explored, involving natural or synthetic hormone combinations tailored to the individual. These treatments may be complemented by herbal medicines, vitamin and mineral supplements, and lifestyle modifications to achieve optimal results. The selection of the most suitable therapy is determined after identifying the root cause of the thyroid dysfunction.

There are several common factors that can lead to thyroid dysfunction, including:

  • Autoimmune thyroiditis or Hashimoto’s thyroiditis
  • Iodine deficiency
  • Poor conversion of T4 to T3
  • Increased levels of thyroid binding globulin (TBG)
  • Thyroid surgery, ablation, or radiation treatment

For prospective patients seeking to transition from prescription Synthroid to natural Desiccated Thyroid or Sustained-release T3, this can be effectively managed under my guidance in prescribing thyroid hormones.

This personalized approach aims to restore optimal wellness by addressing bothersome symptoms, regulating menstrual cycles, improving fertility, and preventing pregnancy loss.
