Symptom #6: Muscle Weakness
About 70% of patients with hyperthyroidism may develop weakness in the proximal muscles. Proximal muscle weakness only affects muscles that are closest to the trunk of the body such as the upper arms and hips.
With treatment and physiotherapy, muscle strength can return to full capacity usually within two months. It is also known as thyrotoxic myopathy. Besides muscle weakness, there is breakdown of muscle tissue and fatigue. Physical activity can often become increasingly difficult.
