Signs and symptoms of Hyperthyroidism may include:
- fast heart rate (100-120 beats per minute or higher)
- slightly elevated blood pressure
- nervousness or irritability
- increased perspiration
- muscle weakness (especially in the shoulders, hips, and thighs)
- trembling hands
- weight loss, in spite of a good appetite
- hair loss
- fingernails partially separated from finger-tips (onycholysis)
- swollen fingertips (achropachy or clubbing)
- retracted (pulled back) upper eyelids
- skin changes
- increased frequency of bowel movements
- goiter (an abnormal swelling in the neck caused by an enlarged thyroid gland)
- in women, decreased menstrual flow and less frequent menstrual flow
- in men, slight swelling of the breasts
- in Graves’ disease: thick or swollen skin over the shin bones (pretibial myxedema); eyes that seem to be popping out of their socket (exophthalmos).
Most of these conditions will return to normal after the hyperthyroidism is treated. Certain others may be treated separately.
