Prepare a brief written report of about 400 words, in which you include the following information. 2.1 Which endocrine gland secretes the hormone, that, by under- or over-secretion, causes the disorder? 2.2 Where in the human body is this endocrine gland located? 2.3 Define the endocrine disorder.2.4 Suggest possible causes of the disorder.2.5 Describe the effects of the disorder on the human body.2.6 What treatments are currently available for this disorder?

2.1 The endocrine gland that secretes the hormone causing the disorder is the thyroid gland.

2.2 The thyroid gland is located in the front of the neck, just below the Adam's apple.

2.3 The endocrine disorder associated with the thyroid gland is called hypothyroidism. It is characterized by an underactive thyroid gland, resulting in lower than normal levels of thyroid hormone in the body.

2.4 There are several possible causes of hypothyroidism. One common cause is an autoimmune disease called Hashimoto's thyroiditis, where the body's immune system attacks and damages the thyroid gland. Other causes include radiation therapy, surgical removal of the thyroid gland, certain medications, and problems with the pituitary gland or hypothalamus that control the thyroid gland's hormone production.

2.5 Hypothyroidism can have various effects on the human body. Some common symptoms include fatigue, weight gain, cold intolerance, dry skin, constipation, and changes in mood or depression. It can also lead to complications such as goiter (enlarged thyroid gland), heart problems, infertility, and developmental issues in children.

2.6 The treatment for hypothyroidism is usually lifelong hormone replacement therapy with synthetic thyroid hormone medication, typically levothyroxine. The medication is taken orally and helps to restore normal thyroid hormone levels in the body. The dosage is carefully adjusted based on the individual's specific needs and regular monitoring of thyroid hormone levels. With proper medication, most people with hypothyroidism can lead normal, healthy lives. Regular check-ups and adjustments to medication may be necessary to ensure optimal hormone levels and manage any potential complications.
