The main treatment for hypothyroidism is synthetic thyroid hormone in pill form to replace what’s missing. Depending on the reason for the slow thyroid, adding more iodine to the diet and generally eating a healthy diet can help.

It is used to decrease the thyroid hormone that is overproduced. Another medication that is used to decrease thyroid hormone is propylthiouracil, frequently known as PTU (Hopfer & Hazard, 2009). The mechanism of action is similar to methimazole by preventing the synthesis of thyroid hormone (Hopfer & Hazard, 2009). Both of these medications are used as a treatment alone, or used before radioactive iodine and surgical options (Hopfer & Hazard, 2009). Beta blockers can be used in conjunction with the antithyroid medication for controlling the increased heart rate, helping to prevent palpitations (Diseases and conditions,

Graves’ Disease is diagnosed based on a series of blood tests, in addition to displaying several symptoms. Laboratory work seeks to discover elevated levels of serum thyroxine (T4) and triiodothyronine (T3) associated with TSH [2]. T3 and T4 help control the body’s metabolism and are needed for normal growth of the developing brain. TSH or thyroid-stimulating hormone is necessary to check for thyroid gland problems and how significant the issue is. One can be diagnosed from a small risk case, in which it can be controlled by medication, to a big risk bringing thyroid cancer into consideration.

The patient’s diagnosis is primary overt hypothyroidism. The patient presents with certain features such as weight gain, weakness, excessively dry flaking skin, dry hair, sluggish movements, constipation, bradycardia, diminished deep tendon reflexes, and bilateral edematous hands, which is classical signs and symptoms for primary hypothyroidism. The patient laboratory test reveals she has an elevation in serum thyroid stimulating hormone level along with low serum free thyroxin and triiodthyronine levels, which indicates it is a dysfunction or abnormality in the thyroid gland as opposed to the pituitary gland or hypothalamus (Gaitonde; Lohano; Porth, 2015, p. 780; Ross, 2014).

Thyroid hormone deficiency in the body is risky to the malfunction of the vital organs. Alterations like lowering and slowing of the biological processes in the body are assumed by the illness. These variations may replicate those that come about with age. The symptoms associated with hypothyroidism may be difficult to describe especially in the old persons. Hypothyroidism can show different manifestations and signs, depending on the health condition, age and sex of the patient. Thus, for it to be treated appropriately, the nursing practitioner has to have the correct diagnosis (Garber, 2012). Since the disorder is more evident at old age, it is, therefore, vital for thyroid disorder among the aged to be a matter of discussion (Laurberg, 2005). Thus, this thesis aims at discussing the effects of hypothyroidism to a seventy years old male

The thyroid stimulating hormone receptors are G-protein linked and are found extracellularly in the thyroid glands. When activated, synthesis of hormonally active iodothyronines T3 (triiodothyronine) and T4 (thyroxine) begins (Park and Chatterjee, 2005). This process begins with iodide is transported into the thyroid gland by the sodium iodide symporter found in the membrane of thyroid follicular cells (Park and Chatterjee, 2005). The iodotyrosine residues monoiodotyrosine and diiodotyrosine are then formed through iodine organification where the iodide is oxidised using hydrogen peroxide and then bound to tyrosine in the thyroglobulin (Park and Chatterjee, 2005). The residues then bind together to form the hormonally active iodothyronines aforementioned (Park and Chatterjee, 2005). Many catalytic enzymes mediate this process and are needed to ensure proper thyroid hormone synthesis. Failure in any steps of the synthesis process leads dyshormonogenesis and could be the result of genetic defects. Adequate synthesis of active thyroid hormone is necessary for the regulation of many developmental processes (Richter, C. et al.,

Graves’ disease, also known as hyperthyroidism is an autoimmune disorder that occurs when antibodies overstimulate thyroid stimulating hormone (TSH). Hyperstimulation of TSH receptors leads to an increased amount of circulating triiodothyronine (T3) and thyroxine (T4). An increased production of T3 and T4 lead to an increased metabolic rate. This can lead to clinical manifestations of diaphoresis, heat intolerance, increased cardiac output, tachycardia, exophthalmos and weight loss. If untreated, hyperthyroidism can turn into a thyrotoxic crisis, triggered by stressful events. Thyrotoxic crisis exceeds the metabolic strains on the body. Clinical manifestations such as hyperthermia, tachycardia, and heart failure can lead to death within forty-eight

How does Graves’ disease treated? There are few options, it can be treated with antithyroid medications; methimazole (Tapazole) & propylthiouracil (PTU), radiation therapy (Radioactive iodine) and lastly surgical therapy. Patients that on antithyroid medications are typically utilized mixes of 1-thyroxine-the alleged piece and substitute regimen, which is connected with a decreased rate of iatrogenic hypothyroidism. Patients with Graves’ disease that became pregnant has a high risk of spontaneous abortion, premature birth and even fetal death, but can be lessened with the use of antithyroid drugs (propylthiouracil) (Momotani et

The main goal of the treatment is to control the over-production o thyroid hormones. The anti-thyroid medications, for instance, have methimazole and propylthiouracil (PTU), which blocks the production of hormones of the thyroid gland. However, there could be some side effects such as allergies and hyperthyroidism may return if the drug is not being used. Sometimes, radioactive iodine treatment is preferred by doctor because it provides a long-term solution, unlike the medications. According to Toft, “Radioactive iodine works by destroying thyroid tissue cells, thereby reducing your thyroid hormone levels.” RAI is usually given as a capsule or in a water-based solution, and the treatment may take months to be effective. The last type of treatment is the thyroidectomy, which is a surgery. The removal of the thyroid gland may be required for some patients that cannot take or tolerate the medications or when those medications have no effect in controlling the overproduction of T3 and T4. Although the total removal of the thyroid gland treats most of the patients, the surgery always results in hypothyroidism, which is a condition where the body lacks sufficient thyroid hormones. In this case, patients that undergo total thyroidectomy need to intake a daily

This approach is commonly recommended for the small groupof people who have such low degrees of thyrotoxicosis that ablative therapy with RAI,surgery, or risks of drug effects of antithyroid medications seem unnecessary. Thesepeople often do well with beta-blockers; however, they must be carefully monitoredsince thyrotoxicosis may worsen without warning. Also, the risks of worsening of osteo-porosis and chronic effects of excess thyroid hormone on the heart should be consid-ered. For these reasons, post-menopausal women with brittle bones (see Chapter 14)and people with irregular heart rhythms (see Chapter 25) are appropriately directedtowardRAI

There are two major thyroid hormones made by a healthy gland Triiodothyronine 3 and Thyroxine 4. Replacing one or both of these hormones can alleviate the symptoms caused by the absolute or relative lack of hormones as a consequence of Hashimoto's thyroiditis. The treatment of choice for Hashimoto's thyroiditis is typically synthetic Thyroxine 4 or thyroxine (levothyroxine). Brand names for this medication include Synthroid, Levothroid, and Levoxyl. The medication must be taken indefinitely, and successful treatment alleviates the symptoms and signs of hypothyroidism. Without medication, there is a very little chance the thyroid would be able to maintain hormone levels within the normal range, and symptoms and signs of hypothyroidism would occur or worsen.” (Robert Ferry Jr., MD

, approximately 500 cases have been reported ; in only 5-15% of cases, hyperthyroidism with low RAI uptake in the thyroid bed were found (3,10) . (1,11,13
