In contrast to hypothyroidism, an overactive thyroid is known as hyperthyroidism. Increased thyroid production results in a hastening of your metabolism and other bodily functions. As the amount of thyroid hormone in the form of both T4 and T3 increases, the body becomes hyperactive causing patients to suffer from jitteriness, aggressive and ineffective nutrient consumption, and dangerous energy crashes.
Contributing factors of hyperthyroidism include thyroid nodules, thyroiditis, Plummer’s disease, over-conversion of T4 to T3, liver dysfunction, nutrient deficiencies, heavy metal toxicity, and others. The most common cause of hyperthyroidism is an autoimmune condition known as Graves’ disease.
As thyroid activity continues to increase, the body can suffer from a variety of different symptoms, including:
• Anxiety and/or panic attacks
• Inability to gain weight
• Sudden weight loss
• Excessive sweating
• Irregular or total loss of menstruation
• Insomnia
• Heart palpitations
• Shortness of breath
• Easily triggered reflexes or jumpiness
• Fluctuating highs and lows in energy level
