The document discusses goiter, which is an enlargement of the thyroid gland caused by a lack of iodine. It can be caused by Graves' disease, Hashimoto's disease, or thyroid cancer. Without enough iodine, the thyroid is unable to produce thyroid hormones. Goiter affects the body's homeostasis by preventing the production of thyroid hormones. Common symptoms include a swollen throat and difficulty swallowing or breathing. Treatment options include medication like levothyroxine to replace thyroid hormones, surgery, or radioactive iodine. Consuming iodized salt can help prevent goiter.

thyroid glands grow larger than normal from the lack of iodine Goiter 1
Cause of Disease Lack of Iodine Graves’ disease (over active goiter) Hashimoto's disease (under active goiter) Thyroid cancer Pregnancy Inflammation 2
How Does the Organ Normally Work? 3 3) With the help of other hormones in the body T4 will turn into T3 which is an active hormone. The pituitary releases TSH into the thyroid gland. 2) If the thyroid has the right amount of minerals it will release an inactive hormone T4
How Does the Disease Affect Homeostasis? 4 3 Causing the precursors to the hormone to build up. Causing a Goiter. Without Iodine T4 cannot be released.
Characteristics of Disease A tight feeling in your throat Coughing Difficulty swallowing Difficulty breathing Dizziness Hoarseness Visible Swelling 9
Who is Affected? 15.8% of the world population 10.1% in the Americas 59.9% in Europe 3–7% in the U.S. 54 countries had iodine deficiency 29 countries had excessive iodine intake 43 countries achieved most iodine intake Woman are more affected then men 8
Diagnosis Testing Hormone Test Antibody Test Ultrasound Thyroid Scan Biopsy 5
Prognosis Goiters are not the cause of death but the lack of T4 hormone hurts the heart causing death. 6
Treatment&Prevention Observation Medications- Levothyroxine Helps simulate hormones in pituitary glands Surgery Radioactive iodine Taken orally Destroys Thyroid cells Taking a healthy amount of iodine helps prevent goiters Can be taken through iodized salt 7 10 By Minneford
