Hashimoto’s Thyroiditis: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate Hashimoto’s thyroiditis:

Patients with Hashimoto’s thyroiditis are symptom-free for a long time. Initially, symptoms of hyperthyroidism (overactive thyroid) are occasionally prominent. The so-called “Hashitoxicosis” is an initial phase in which mild hyperthyroidism usually occurs, which then gradually changes to chronic hypothyroidism (underactive thyroid).

Leading symptoms

Basal metabolic rate

  • Drop in body temperature → feeling cold, cold intolerance/cold hypersensitivity.
  • Decreased sweating
  • Doughy, cool-dry skin especially on the face and hands and feet
  • Dull shaggy hair / dry, brittle hair.
  • Dry, brittle nails
  • Weight gain (with poor appetite).

Cardial (cardiovascular)

  • Bradycardia – pulse slowing (< 60 beats/minute) [HMV ↓, cyanosis]

Gastrointestinal (gastrointestinal tract).

  • Constipation (constipation)

Nervous system and psyche

  • Depression
  • Fatigue, listlessness, weakness (increased need for sleep).
  • Muscle weakness
  • Decreased visual reflexes

Further

  • Hypercholesterolemia (lipid metabolism disorder; too high cholesterol in the blood).
  • Hypertriglyceridemia (lipid metabolism disorder; excessive triglyceride levels in the blood).
  • Myxedema – pasty (puffy; bloated) skin showing non-push-in, doughy edema (swelling) that is not position-dependent; facial and peripheral; occurring primarily on the lower legs
  • Peripheral edema – swelling of the legs due to water retention.
  • Rough and deep voice due to vocal fold edema.
  • Cervical (“belonging to the throat”) pressure sensation occasionally; cervical pain (< 5%).

Associated symptoms

  • Anemia (anemia)
  • Alopecia diffusa (diffuse hair loss)
  • Dyspnea (shortness of breath)
  • Dysphonia (hoarse voice)
  • Hypacusis (hearing loss)
  • Hypertension (high blood pressure)
  • Hyporeflexia (lowered intensity of one or more reflexes).
  • Hypoventilation (restricted pulmonary ventilation) and respiratory insufficiency/disruption of external (mechanical) breathing denotes, resulting in inadequate ventilation of the alveoli (myxedema coma; hypothyroid coma).
  • Carpal tunnel syndrome – nerve compression syndrome on the hand.
  • Lack of concentration
  • Menorrhagia – increased and prolonged menstruation.
  • Myopathy of the skeletal muscles (Ck and myoblobin ↑).
  • Oligo- or amenorrhea – infrequent to no menstrual bleeding.
  • Muscle cramps, stiffness
  • Paresthesias (sensory disturbances)
  • Pericardial effusion (pericardial effusion)
  • Right, left ventricular dilatation (permanent expansion of the ventricle) with possible hydropericardium/accumulation of serous fluid in the pericardium [ECG: low voltage of P- and T-wave and QRS complex].
  • Goiter (enlargement of the thyroid gland).
  • Hearing loss
  • Increased incidence of abortions (miscarriages).
  • Decreased libido (sex drive).
  • Confusion
  • Cerebellar ataxia (disorders of movement coordination (ataxia) triggered by pathological changes in the cerebellum).
