Why Thyroid Causes Weight Gain: Key Reasons Explained

Thyroid disorders can significantly impact body weight, especially when hormone levels become imbalanced. An underactive thyroid (hypothyroidism) slows metabolism, leading to weight gain, fatigue, and reduced energy levels. This weight gain is often linked to decreased calorie burning and fluid retention rather than excess fat alone. In some cases, increased appetite or hormonal imbalance may also contribute. Proper diagnosis through thyroid tests and timely treatment can help restore hormone balance and manage weight effectively. Understanding the connection between thyroid function and metabolism is essential for identifying unexplained weight gain and improving overall health outcomes
