Hypothyroidism vs. Hyperthyroidism - 1133 Words

Hypo/Hyperthyroidism Both hypo and hyperthyroidism are a result of a disease in caused by malfunction of the thyroid gland located in the neck as represented by the image below left. The causes of chronic hypothyroidism are fairly distinct. Around the world in third-world and developing countries, iodine deficiency is the most common cause of hypothyroidism. This used to be true as well for developed countries, but today this is a less common cause as iodine usually finds its way into our diets without too much trouble. In modern-day developed countries, hypothyroidism is mainly a result of Hashimotos thyroiditis, a birth defect which lacks a thyroid gland or a deficiency of hormones from either the hypothalamus or the pituitary gland.†¦show more content†¦Hyperthyroidism is caused by an excess of thyroxine (T4) or triiodothyronine (T3), or both. This excess is a result of a malfunction of the thyroid gland as indicated by the picture below. There are many different symptoms of hyperthyroidism, some of the most common being major weight loss despite having a insatiable appetite, anxiety, heat intolerance, fatigue, weakness, hyperactivity, irritability, apathy, depression, and sweating. In addition, many experience shortness of breath, loss of balance, nausea, vomiting, osteoporosis, and diarrhea. However, those who undergo hyperthyroidism later in life may not experience most of these symptoms at all and instead only feel constantly fatigued and considerable weight loss. Nonetheless, neurological symptoms may occur in addition to the physical manifestations. These neurological symptoms include tremor, chorea (ticks), myopathy (muscle weakness), and temporary but periodic paralysis. There are a variety of ways to treat hyperthyroidism, depending on the age of the patient, the size of their thyroid gland, and their general health. The most common treatments include beta-blockers, which do not actually cure hyperthyroidism but mask some of the symptoms such as tremors, anxiet y and so on. This, however, is not advised for those with heart or lung problems. Another possible treatment for this disease is radioactive iodine, or RAI. RAI therapy is the most common treatment for hyperthyroidismShow MoreRelatedHyperthyroidism: Graves Disease and Thyroid Hormone Level977 Words   |  4 Pagesthe correct amount -- not too little and not too much.
