Hyperthyroidism and hypothyroidism are endocrine disorders that alter the normal metabolic rate. Hyperthyroidism is due to oversecretion of the thyroid hormones(thyroxine,triiodothyronine) and causes glucose to be burned by the body at an increased rate. People with hyperthyroidism tend to lose body weight,have increased hunger, show protrusion of the eyeballs(exophthalmia), be irritable, and suffer from tachyarrythmias. These people may complain of nervousness, bowel changes, and a fast heart beat.
Hypothyroidism (undersecretion of thyroid hormones) causes a slow metabolic rate with resultant weight gain, goiter, apathy, and bradycardia. These people may complain of feeling tired all the time and sluggishness.
Both conditions are readily treatable with proper diagnosis. They are also genetically passed from generation to generation.
