Two hormones are produced by the thyroid gland, T4 and T3. T3 is the more active hormone and controls most of the
body’s metabolism. When the thyroid is underactive (low T3) the body functions slow down. Some of the symptoms a
person could experience are weight gain, skin and hair become dry, fluid accumulates in the body, eyebrows thin along
the edges, intolerance to cold, and fatigue. Hyperthyroidism (high T3) can be just as damaging. Symptoms of an
overactive thyroid (high T3) include difficulty gaining weight, nervousness, fast pulse rate, easily flush, and intolerance to
high temperatures.
