Expert Answer:

A hormone   is a chemical released by a cell, a gland, or an organ in one part of the body that affects cells in other parts of the organism.
 Hyperthyroidism:-
Graves's disease, considered an autoimmune disease, shows elevated metabolic rate, excessive perspiration, rapid, irregular heartbeat, nervousness and weight loss
exophthalmos: protrusion of the eyeballs caused by edematous tissue behind the eyes

Hypothyroidism:-

cretinism (infantile hypothyroidism) - shows stunted growth, thickened facial features, abnormal bone development and mental retardation,
myxedema - low metabolic rate, lethargy, weight gain, increase in body fluids
goiter - abnormal growth of the thyroid gland


Hyperinsulinism:-

hypoglycemia - resulting in lack of glucose delivery to the brain causing disorientation, unconsciousness and even death (usually the result of an overdose of insulin)

Hypoinsulinism:-

Type I Diabetes (insulin - dependent diabetes mellitus)- elevated glucose levels in the blood and urine. Over time diabetics experience vascular and neural problems. Secondarily, poor circulation may lead to gangrene, blindness, kidney damage and impotence.
Type II Diabetes - while occurring later in life, the conditions and problems that accompany Type I diabetes occur here as well. There are many hormones which have different functions like this.
