How does thyroid dysfunction affect metabolism?

Thyroid hormones, especially T3 and T4, play a vital role in regulating metabolism. When thyroid function is impaired, it can cause significant metabolic changes. In hypothyroidism, lower hormone levels slow down metabolism, leading to weight gain, fatigue, and cold intolerance. Conversely, hyperthyroidism speeds up metabolism, causing weight loss, nervousness, and heat intolerance. A thyroid function test (TFT) helps assess hormone levels, and treatment can help restore normal metabolic function. Proper thyroid management is crucial for maintaining a balanced metabolism and overall well-being.
