                                Hyperthyroidism Symptoms

Hyperthyroidism refers to an overactive thyroid, in which the thyroid gland produces excessive amounts of thyroid hormones (T3 & T4).

When the thyroid gland is overactive, it overstimulates metabolism and aggravates the effect of the sympathetic nervous system, causing the body’s processes to speed up.

Symptoms of hyperthyroidism include:
     -Nervousness or anxiety, irritability.
     -Heart palpitations, hand tremors.
     -Excessive sweating & heat intolerance, in which
     -The skin is continuously flushed, warm, soft, & moist, 
     -However, elderly patients may report dry skin with itching.
     -Tachycardia (fast heartbeat), Atrial fibrillation, and elevated systolic BP.
     -Hyperactivity, insomnia, increased metabolic rate, increased frequency of bowel 
      movements, and weight loss despite increased appetite.
     -Osteoporosis & fracture, fine, brittle hair, with hair loss, muscle aches & weakness, 
      fatigue, light or infrequent menstrual cycles & problems with fertility.

The course of the disease may be mild or may progress continuously if untreated, leading to:
  intense nervousness, 
        and eventually heart failure.
