It is estimated that between 1 percent and 4 percent of adults have moderate to severe hypothyroidism, and 10 percent to 12 percent have mild or subclinical hypothyroidism.
Symptoms of hypothyroidism (underactive thyroid) include: fatigue, weakness, cold hands and feet, low body temperature, dry sparse hair, dry skin, weight gain despite loss of appetite, poor memory, low sex drive, slow pulse, low blood pressure, and menstrual irregularities, to name a few. Symptoms of hyperthyroidism (overactive thyroid) include: weight loss, increased appetite, restlessness, nervousness, irritability, overactivity, increased heart rate, heart palpitations, increased sweating, tremors, shakiness, double vision, and protrusion of eyes.
Evidence supports that certain cases of thyroid disorders may result from the malfunction of nerves in the brain and spinal cord that control the thyroid's production of thyroid hormone. Whether too little or too much thyroid hormone is produced, the abnormal level can be due to a malfunction between the brain, pituitary, spinal cord, and thyroid, as a result of spinal subluxations (spinal distortions that irritate nerves). Chiropractors help restore normal nerve function and communication, thereby allowing your body to work normally and naturally.
