Thyroid Causes Weight Gain: Key Reasons Explained

Thyroid disorders, especially hypothyroidism, are a common cause of unexplained weight gain due to their impact on metabolism and overall body function. When the thyroid gland produces insufficient hormones, the body’s metabolic rate slows down, leading to fewer calories burned and increased fat storage. This condition can also cause fatigue, reduced physical activity, fluid retention, and changes in appetite, all of which contribute to gradual weight gain. In many cases, the weight increase is modest and may be linked to water retention rather than excess fat. Other symptoms like sluggishness, dry skin, and hormonal imbalance may also appear alongside weight changes. Early diagnosis through blood tests and proper medical treatment can help restore hormone balance and manage weight effectively.
