Overview
History and Symptoms
Silent thyroiditis features a small goiter without tenderness and, like the other types of resolving thyroiditis, tends to have a phase of hyperthyroidism followed by a phase of hypothyroidism then a return to euthyroidism.[1] The time span of each phase is not concrete, but the hypo- phase usually lasts 2-3 months.
The symptoms are those of hyperthyroidism and hypothyroidism during these phases.
The earliest symptoms result from an overactive thyroid gland (hyperthyroidism). These symptoms may last for 3 months or fewer. Later symptoms may be of an underactive thyroid (including fatigue and cold intolerance) until the thyroid recovers.
Symptoms are usually mild and may include:
- Fatigue
- Frequent bowel movements
- Heat intolerance
- Increased appetite
- Increased sweating
- Irregular menstrual periods
- Irritability
- Muscle cramps
- Nervousness, restlessness
- Palpitations
- Weakness
- Weight loss
