Fast heartbeat, a condition called tachycardia.
Irregular heartbeat, also called arrhythmia.
Pounding of the heart, sometimes called heart palpitations.
Increased hunger.
Nervousness, anxiety and irritability.
Tremor, usually a small trembling in the hands and fingers.
Sweating.
Changes in menstrual cycles.
Increased sensitivity to heat.
Changes in bowel patterns, especially more-frequent bowel movements.
Enlarged thyroid gland, sometimes called a goiter, which may appear as a swelling at the base of the neck.
Tiredness.
Muscle weakness.
Sleep problems.
Warm, moist skin.
Thinning skin.
Fine, brittle hair.
