If the patient had an underactive thyroid gland (hypothyroidism) instead, what will their TSH and thyroid hormones levels look like? low TSH, high T3 and T4 high TSH , high T3 and T4 low TSH, low T3 and T4 high TSH, low T3 and T4

Step 1
The thyroid gland produces thyroid hormones, primarily triiodothyronine (T3) and thyroxine (T4), which regulate metabolism. The pituitary gland produces thyroid-stimulating hormone (TSH) to stimulate the thyroid gland to produce these hormones. Show more…

Based on what you know about negative feedback mechanisms in the endocrine system, which of the following lab results would indicate hypothyroidism due to primary thyroid disease (assuming that it was possible to get results for all three hormones)? low TSH high TSH low T4 high T4 low TRH (thyrotropin releasing hormone) high TRH (thyrotropin releasing hormone)

Keeping in mind the hormonal control of T3 and T4 secretion as well as some of the basic physiological functions of T3 and T4, classify the following statements at left as being characteristic of: Hypothyroidism Hyperthyroidism Symptoms include fatigue, changes in skin tone, hair, appetite, and mental function. Thyrotoxicosis is another name for this disease. Symptoms include heat intolerance and weight loss. Symptoms include cold intolerance and weight gain. Hashimoto's disease is one autoimmune cause of this condition. If untreated, myxedema, or puffiness of the face and other regions, can occur. Plasma T3 and T4 levels are chronically above normal. Symptoms include cold intolerance and weight gain. Treatment may include surgical removal of the thyroid gland or drugs that inhibit thyroid hormone synthesis. Results from damage to or loss of functional thyroid tissue. Symptoms often include increased nervous system activity such as anxiety, tremors, jumpiness, and increased heart rate. Symptoms include heat intolerance and weight loss. Plasma T3 and T4 levels are chronically below normal. Graves' disease is an autoimmune disease that is the most common cause. Iodine deficiency is one cause, which leads to elevated TRH, TSH, and a goiter. Can result from hormone-secreting tumors of the thyroid gland.

Fill out the chart below. Record whether the hormone levels are expected to be high, low, or either. For antibody/immunoglobulins and goiter, answer yes, no, or possible. (The antibodies and immunoglobulins in question are those specific to the thyroid disorder.) (2 points) Primary hypothyroidism (iodine deficiency) | Graves' disease | Hashimoto's Thyroiditis | TRH-secreting tumor | TSH-secreting tumor | TRH-suppressing tumor | TSH-suppressing tumor TRH levels TSH levels T3 and T4 levels Antibodies or immunoglobulins? Goiter? Is patient hyper- or hypothyroid? Use the chart below to record whether the hormone levels are expected to be high, low, or either. For antibody/immunoglobulin and goiter, answer yes, no, or possible. (2 points) Hypothyroidism | Hyperthyroidism TSH level T3 and T4 levels Antibodies or immunoglobulins? Goiter?
