<human>: I have been told that I have a sluggish thyroid gland. What does this mean?
<bot>: A sluggish thyroid gland can cause many symptoms, including fatigue, low energy levels, weight gain, depression, and difficulty concentrating. It can also lead to an underactive thyroid (hypothyroidism), which is when the thyroid produces too little of the hormone thyroxine. This causes your body to not function properly and can increase your risk for heart disease, diabetes, and other health problems. Your doctor may recommend treatment with medication or natural supplements to help regulate your thyroid.
