Hashimoto's Thyroiditis

Evidence-based clinical insights and management strategies by Dr. Ibrar Ahmad.

📌

Key Facts

Hashimoto's disease is an autoimmune disorder that can cause hypothyroidism, or underactive thyroid. It is the most common cause of hypothyroidism in developed countries.

🧬

Pathophysiology

The immune system creates antibodies (Anti-TPO and Anti-Tg) that attack the thyroid gland. This leads to chronic lymphocytic infiltration and progressive destruction of thyroid follicles, eventually resulting in hormone deficiency.

Symptoms & Clinical Features

Slow onset of hypothyroidism symptoms (fatigue, weight gain, cold intolerance).
Enlargement of the thyroid (goiter) which may feel firm or "rubbery".
Difficulty swallowing if the goiter is large.

Diagnosis

High TSH and low Free T4 indicate hypothyroidism. The presence of Thyroid Peroxidase (TPO) antibodies and Antithyroglobulin antibodies confirms Hashimoto's as the underlying cause.

📊

Diagnostic Pathway

1
Initial Screening

Symptom review and baseline hormonal blood tests.

2
Confirmatory Testing

Advanced diagnostic protocols (e.g., OGTT, MRI, Suppression tests).

3
Personalized Plan

Tailored treatment strategy based on clinical results.

Treatment & Management

The primary treatment is thyroid hormone replacement therapy with Levothyroxine. Regular monitoring is required to adjust the dose as the autoimmune destruction of the gland progresses over time.
