Little-Known Signs Your Thyroid Is Out of Whack

29. Unexplained Muscle Atrophy or Weakness

Beyond general muscle and joint pain, a significant red flag for thyroid dysfunction is unexplained muscle atrophy or weakness. In severe cases of hypothyroidism, a lack of thyroid hormones can slow down the repair and maintenance of muscle tissue, leading to a gradual loss of muscle mass. For those with hyperthyroidism, the body's accelerated metabolism can cause muscles to break down at an increased rate, resulting in overall weakness and a difficulty with strength-based activities. If you are losing muscle mass without explanation, it is a sign that your metabolic engine may be running too slow or too fast.

30. Increased Thirst and Frequent Urination

If you find yourself constantly thirsty and needing to urinate more often than usual, it could be a sign of a hyperactive thyroid. The body's metabolism is in overdrive, which can lead to increased fluid intake and output. Conversely, hypothyroidism can cause a decreased sense of thirst and less frequent urination. These changes, though often dismissed, are a clear indication that your body is struggling to maintain fluid balance and that your thyroid is impacting your metabolic functions.
