Understanding Hypothyroidism vs Hyperthyroidism & Therapy

The Miley Clinic24 Jan, 2026Other

Hypothyroidism vs hyperthyroidism involves underactive versus overactive thyroid function. Hypothyroidism causes fatigue, weight gain, and cold intolerance due to low hormone levels, while hyperthyroidism leads to weight loss, anxiety, and heat sensitivity from excess hormones. Thyroid replacement therapy effectively treats hypothyroidism by supplementing levothyroxine to restore normal levels, whereas hyperthyroidism often requires antithyroid drugs, beta-blockers, or other interventions.
