Ok Everybody I am not discouraged just disappointed.
I had my WI this morning and I always weigh at home before I go, in the same clothes and shoes every time. At home I had lost 2.4 pounds but at weigh in I had only lost 1.8 pounds, (not that 1.8 pounds is not good). When I got home I weighed again and sure enough I had lost 2.4 pounds. Well, I sat through the whole meeting wondering what had happened. Then one of the ladies said she was very upset and that she had gained 2 pounds and she knew it should be a loss. Then the leader said that Jim one of our guy members had lost 19 pounds this morning when he stepped on the scale... of course, they had him re-weigh and he had actually
(?or not?) lost 4.2 pounds. Then the leader said that they were having trouble with the computers this morning. I think that the scale is wrong today. I wonder how many other people there felt like I did. SO to make a long story short... I am not believeing that I only lost 1.8 pounds because my scales always matched theirs before. But on the good and upside of that next week should be a bigger loss if I play catch up with this weeks weigh in not registering correct.
What are thyroid hormones?
Thyroid hormones are produced by the thyroid gland. This gland is located in the lower part of the neck, below the Adam's apple. The gland wraps around the windpipe (trachea) and has a shape that is similar to a butterfly - formed by two wings (lobes) and attached by a middle part (isthmus).
The thyroid gland uses iodine (mostly available from the diet in foods such as seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3), which account for 99.9% and 0.1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted into T3 - the active hormone that affects the metabolism of cells.
Thyroid hormone regulation- the chain of command
The thyroid itself is regulated by another gland that is located in the brain, called the pituitary. In turn, the pituitary is regulated in part by the thyroid (via a "feedback" effect of thyroid hormone on the pituitary gland) and by another gland called the hypothalamus. The hypothalamus releases a hormone called thyrotropin releasing hormone (TRH), which sends a signal to the pituitary to release thyroid stimulating hormone (TSH). In turn, TSH sends a signal to the thyroid to release thyroid hormones. If a disruption occurs at any of these levels, a defect in thyroid hormone production may result in a deficiency of thyroid hormone (hypothyroidism).
Goiters and Nodules.
Goiter is an enlargement of the thyroid gland. When all of the thyroid tissue is enlarged, called a diffuse goiter, the cause may be manifold, including Graves' or Hashimoto's disease, congenital goiter, and iodine deficiency in those areas of the world where iodine intake is particularly low. Goiter is therefore a reflection of a disease process and may occur with or without thyroid dysfunction. Once the cause of goiter is determined, specific treatment can be prescribed.
Goiter is frequently caused by lumps or nodules in the thyroid, which may be cysts, inflammation, or benign or malignant tumors. The physician can feel single or multiple nodules in 4 to 7 percent of the adult population in the United States. Nodules are found at a much higher frequency by applying ultrasound
(sonography) or computerized tomography
to the thyroid area. Similar to other thyroid diseases, most patients are female. Current estimates are that the annual incidence of thyroid nodules discovered by examination is about 0.1 percent of the adult population. However, the annual incidence of thyroid cancer is about 0.004 percent. Therefore, only about one in twenty newly discovered thyroid nodules are likely to be malignant.
Upon discovery of a thyroid nodules(s), the physician's main concern should be to determine whether the nodule is benign or malignant. The cornerstone for this determination is the fine-needle aspiration biopsy
, a procedure in which a very fine needle is inserted directly through the skin into the nodule and, with gentle suction, cells from the nodule are aspirated, placed on glass slides, stained, and evaluated by microscopy. The biopsy, done with or without direct visualization by sonography
, is a simple, safe, and relatively painless office procedure. The sensitivity for detection of thyroid cancer is about 85 percent and the specificty is about 92 percent. Cytology results in a diagnosis in 85 percent of samples, with 75 percent being benign, 5 percent being malignant and 20 percent suspicious for malignancy
. The remaining samples are nondiagnostic or unsatisfactory samples. The experience of the operator and cytologist has a large influence on these results.
Have a great day and keep
