Hypothyroidism

Hypothyroidism is a systemic metabolic state resulting from insufficient thyroid hormone (thyroxine, T4; triiodothyronine, T3) synthesis, secretion, or tissue action. It leads to a generalized slowing of metabolic processes.

• Primary (Thyroid gland failure): Autoimmune thyroiditis (Hashimoto's disease - most common in iodine-sufficient regions), iatrogenic (radioiodine ablation, thyroidectomy), iodine deficiency or excess, medications (lithium, amiodarone, checkpoint inhibitors).
• Secondary/Tertiary (Central): Pituitary tumors, surgery, radiation, or hypothalamic dysfunction.

Decreased circulating levels of T4 and T3 impair cellular transcription of metabolic proteins. In Hashimoto's thyroiditis, CD4+ and CD8+ T-lymphocytes destroy thyroid follicular cells, leading to follicular atrophy, oncocytocytic changes (Hürthle cells), and fibrosis. The loss of negative feedback on the anterior pituitary stimulates increased thyroid-stimulating hormone (TSH) secretion.

• Prevalence: ~4.6% of the US population (mostly subclinical).
• Demographics: Females are affected 5 to 10 times more frequently than males. Incidence increases with age, peaking after 60 years.

• Female sex and age >60 years.
• Family history of thyroid or autoimmune diseases.
• Personal history of Type 1 Diabetes, Celiac disease, or rheumatoid arthritis.
• Prior head/neck radiation or thyroid surgery.

• Vitals: Bradycardia, diastolic hypertension, hypothermia.
• Inspection/Palpation: Coarse, dry, pale skin; brittle nails; thinning hair (lateral third of eyebrows); non-pitting edema; diffuse, firm goiter (Hashimoto's) or impalpable thyroid (atrophic).
• Neurological: Delayed relaxation phase of deep tendon reflexes (Woltman's sign).

Diagnosis relies on clinical assessment, serum TSH, and Free T

1. Thyroid ultrasound is used for structural anomalies. Differential diagnoses include clinical depression and nephrotic syndrome.

Thyroid Stimulating Hormone (TSH)

• Type: Blood Test


• Purpose: Primary screening tool for thyroid dysfunction.


• Expected Findings: Elevated (primary hypothyroidism) or low/normal (central hypothyroidism).


• Interpretation: High TSH with low Free T4 confirms primary hypothyroidism. Free Thyroxine (Free T4)


• Type: Blood Test


• Purpose: Assess active unbound hormone levels.


• Expected Findings: Low.


• Interpretation: Low Free T4 with high TSH establishes overt primary hypothyroidism. Anti-Thyroid Peroxidase (Anti-TPO) Antibodies


• Type: Blood Test


• Purpose: Evaluate for autoimmune etiology.


• Expected Findings: Elevated.


• Interpretation: Confirms Hashimoto's thyroiditis.

• Thyroid Ultrasound: Evaluates gland size, echogenicity (diffuse heterogeneity in autoimmune thyroiditis), and suspicious nodules.

• Major Depressive Disorder: Shares fatigue and cognitive slowing; distinguished by normal TSH and Free T

• Nephrotic Syndrome: Presents with generalized edema; distinguished by normal TSH, hypoalbuminemia, and massive proteinuria.

• Myxedema coma (highly fatal).
• Atherosclerotic cardiovascular disease (secondary to hyperlipidemia).
• Infertility and obstetric complications (preeclampsia, miscarriage).

Excellent. Overt primary hypothyroidism resolves entirely with lifelong daily levothyroxine therapy. Normal life expectancy is restored with adherence.

• Secondary prevention via routine neonatal TSH screening and monitoring high-risk adults.
