Top 14 Signs and Symptoms of Hypothyroidism

Do you have Hypothyroidism?

You may have Hypothyroidism even if your Thyroxine levels show normal. It is called:

  • Subclinical hypothyroidism: Normal Thyroxine and high TSH with no symptoms.
  • Grade 1 Hypothyroidism: Normal Thyroxine and TSH > upper limit of reference range (10mlU/L)
  • Grade 2 Hypothyroidism: Normal Thyroxine and TSH 10.1 – 20 mlU/L
  • Grade 3 Hypothyroidism: Normal Thyroxine and TSH > 20 mlU/L
  • Clinical or overt hypothyroidism: Low Thyroxine and high TSH
  • Primary Hypothyroidism is characterized by low thyroid hormone and high TSH blood levels.
  • Secondary Hypothyroidism is characterized by low thyroid hormone and low TSH levels.
  • Cellular Hypothyroidism is characterized by normal thyroid hormone, TSH levels and low functional thyroid activity (as defined by a low basal metabolic rate).

Signs and symptoms of Hypothyroidism

  1. Central nervous system: Depression, fatigue, forgetfulness, decreased concentration, memory deficit, slow thinking, cold intolerance, decreased sweating, ataxia (loss of full body movements), headaches.
  2. Muscloskeletal: Muscular weakness, cramps, myalgia (muscular pain), arthralgia (pain in joint)and delayed relaxation phase of reflexes.
  3. Cardiovascular: Bradycardia (abnormal heart rate), diastolic hypertension, high LDL, ascites (abdominal swelling), poor circulation (cold extremities), hyperhomocysteinemia.
  4. Haematological: Iron deficiency anaemia
  5. Respiratory: Shortness of breath
  6. Gastrointestinal: Anorexia, reduced appetite, constipation, sluggish bowel transit time associated with flatulence, or bloating.

  9. Genitourinary (Genital and urinary organs): impaired kidney function
  10. Female reproductive: low libido, infertility, irregular menstrual cycle, Menorrhagia (heavy bleeding at menstruation), galactorrhoea (excessive milk production), hyperprolactinaemia (high prolactin), fibrocystic breast disease (lumpiness in breasts)
  11. Male reproductive: Low libido, infertility, impotence, hyperprolactinaemia (high prolactin).
  12. Integumentary: Dry skin and mucous membranes (mouth, vagina, anus), coarse skin, brittle and coarse hair and nails, hair loss, thin and brittle nails.

Many studies show a strong link between thyroid dysfunction, infertility, miscarriages, premature delivery and stillbirths. Untreated hypothyroidism may cause miscarriages, infertility, premature delivery or stillbirths.
