Learn Thyroid Gland Anatomy Hormones Problems, Symptoms and Treatment |

The thyroid is a butterfly-shaped endocrine gland located in the Thyroid Gland Anatomy Hormones Problems neck it is wrapped around the trachea just below the thyroid cartilage the Adam's apple the two major hormones of the thyroid or triiodothyronine t3 and thyroxine t4 the numbers Thyroid Gland Anatomy Hormones Problems three and four indicate the number of iodine atoms present in a molecule of each hormone t3 and t4 are collectively Thyroid Gland Anatomy Hormones Problems referred to as thyroid hormones thyroid hormone Thyroid Gland Anatomy Hormones Problems secretion is under control of thyroid stimulating hormone TSH from the anterior pituitary TSH in turn is induced by thyrotropin-releasing hormone Thyroid Gland Anatomy Hormones Problems T or H produced by the hypothalamus the amount of circulating thyroid hormones is regulated by a negative feedback loop when their levels are Thyroid Gland Anatomy Hormones Problems too high they suppress the production of TSH and t rh consequently inhibiting their own production thyroid hormones act to Thyroid Gland Anatomy Hormones Problems increase the body's metabolic rate they stimulate appetite Thyroid Gland Anatomy Hormones Problems digestion breakdown of nutrients and absorption Thyroid Gland Anatomy Hormones Problems they also increase oxygen consumption raise the Thyroid Gland Anatomy Hormones Problems breathing rate heart rate and contraction strength as a result Thyroid Gland Anatomy Hormones Problems the body's heat production is increased thyroid hormone Thyroid Gland Anatomy Hormones Problems secretion usually rises in winter months to keep the body warm.


There are two major groups of thyroid problems Thyroid Gland Anatomy Hormones Problems hypothyroidism when the thyroid does Thyroid Gland Anatomy Hormones Problems not produce enough hormones resulting in a low Thyroid Gland Anatomy Hormones Problems metabolic rate combined with slow respiratory and cardiovascular Thyroid Gland Anatomy Hormones Problems activities common symptoms include fatigue Thyroid Gland Anatomy Hormones Problems weight gain despite poor appetite cold intolerance slow heart rate heavy menstrual bleeding and constipation iodine deficiency and Thyroid Gland Anatomy Hormones Problems Hashimoto's thyroiditis are the most common causes Hashimoto's thyroiditis is an autoimmune disease in which the thyroid gland is gradually destroyed by Thyroid Gland Anatomy Hormones Problems the body's own immune system hypothyroidism Thyroid Gland Anatomy Hormones Problems especially when caused by iodine deficiency may lead to Thyroid Gland Anatomy Hormones Problems swelling of the thyroid gland known as goiter in an Thyroid Gland Anatomy Hormones Problems attempt to fix the low levels of thyroid hormones the Thyroid Gland Anatomy Hormones Problems pituitary produces more TSH to further stimulate Thyroid Gland Anatomy Hormones Problems the thyroid gland the thyroid while unable to make hormones.

Without iodine response to TSH by growing in size Thyroid Gland Anatomy Hormones Problems hypothyroidism is managed with thyroxine hormone replacement hyperthyroidism when the thyroid gland produces too much Thyroid Gland Anatomy Hormones Problems hormones resulting in a too active metabolism Thyroid Gland Anatomy Hormones Problems together with respiratory and cardiovascular rates that Thyroid Gland Anatomy Hormones Problems are higher than necessary common symptoms include Thyroid Gland Anatomy Hormones Problems irritability insomnia weight loss despite good appetite Thyroid Gland Anatomy Hormones Problems heat intolerance heart racing and diarrhea hyperthyroidism Thyroid Gland Anatomy Hormones Problems is most commonly caused by Graves disease another autoimmune disorder characterized by presence of an antibody called thyroid stimulating Thyroid Gland Anatomy Hormones Problems immunoglobulin TSI TSI similar to TSH stimulates the thyroid gland to produce hormones unlike TSH however TSI is not Thyroid Gland Anatomy Hormones Problems regulated by negative feedback mechanisms leading to Thyroid Gland Anatomy Hormones Problems uncontrolled production of thyroid hormones TSI also Thyroid Gland Anatomy Hormones Problems stimulates the thyroid gland to grow which may lead to formation Thyroid Gland Anatomy Hormones Problems of a goiter hyperthyroidism may be managed with drugs Thyroid Gland Anatomy Hormones Problems that suppress thyroid function radioactive iodine that selectively destroys the thyroid gland or surgery that removes part of the gland.

We're gonna see a few facts on thyroid nodules Thyroid Gland Anatomy Hormones Problems what are tired nodules thyroid nodules are basically Thyroid Gland Anatomy Hormones Problems extra growth from the thyroid gland and how do you Thyroid Gland Anatomy Hormones Problems know if one has a thyroid nodule thyroid nodule sometimes Thyroid Gland Anatomy Hormones Problems comes to attention when patients feel their Thyroid Gland Anatomy Hormones Problems neck and they find something lumpy or bumpy Thyroid Gland Anatomy Hormones Problems in their neck second if your doctor is feeling your Thyroid Gland Anatomy Hormones Problems neck and they feel something abnormal in the regional thyroid gland it may come to attention in that way but more Thyroid Gland Anatomy Hormones Problems importantly in this day and age we're imaging tests like CT scans MRIs are being done.

You know for various indications Thyroid Gland Anatomy Hormones Problems maybe you went for a neck pain you got a CT scan or an MRI Thyroid Gland Anatomy Hormones Problems you went for a vascular dopper of your neck and Thyroid Gland Anatomy Hormones Problems these tests sometimes also pick up thyroid nodules Thyroid Gland Anatomy Hormones Problems in addition to their you know original testing and this is Thyroid Gland Anatomy Hormones Problems what we call as thyroid incidental nodules where you Thyroid Gland Anatomy Hormones Problems did the test for some other reason but then you found the Thyroid Gland Anatomy Hormones Problems thyroid had some non-diverse and this is one of the Thyroid Gland Anatomy Hormones Problems common reasons why patients are referred to an Thyroid Gland Anatomy Hormones Problems endocrinologist with the history of thyroid with a pickup Thyroid Gland Anatomy Hormones Problems of thyroid nodules how do you go about Thyroid Gland Anatomy Hormones Problems managing thyroid nodules in general ninety-five Thyroid Gland Anatomy Hormones Problems percent of thyroid nodules are benign they are not Thyroid Gland Anatomy Hormones Problems cancerous what about five percent of cases where the thyroid nodule can be cancerous does it affect the thyroid function.

In general not majority of thyroid nodules Thyroid Gland Anatomy Hormones Problems do not cause any changes to your thyroid functions what do we Thyroid Gland Anatomy Hormones Problems do as a first step in one somebody decides it or somebody knows that they have a thyroid nodule the first important step is to get a good Thyroid Gland Anatomy Hormones Problems quality ultrasound by an experienced sonographer a good Thyroid Gland Anatomy Hormones Problems quality ultrasound will tell us various characteristics Thyroid Gland Anatomy Hormones Problems of the non-dual that can describe in such a way that Thyroid Gland Anatomy Hormones Problems one can make a good impression out of it to decide if Thyroid Gland Anatomy Hormones Problems the non-dual is benign appearing where there is not it is Thyroid Gland Anatomy Hormones Problems not something that needs to be worried about or Thyroid Gland Anatomy Hormones Problems something that is more malignant appearing where it is Thyroid Gland Anatomy Hormones Problems something that needs to be worried about and further steps Thyroid Gland Anatomy Hormones Problems need to be taken after doing the ultrasound will be to decide on a Thyroid Gland Anatomy Hormones Problems fine needle aspiration psychology what does a fine needle aspiration cytology or a Fenny.

See the simple needle test where the doctor Thyroid Gland Anatomy Hormones Problems who's performing the test actually puts a small needle Thyroid Gland Anatomy Hormones Problems into the non-dual and nothing nothing to be worried about Thyroid Gland Anatomy Hormones Problems this is a common procedure done this is the size of the Thyroid Gland Anatomy Hormones Problems needle that is used for these procedures are in fact smaller than the one that is used for a blood draw and it is usually done under ultrasound Thyroid Gland Anatomy Hormones Problems guidance so that one is acts actually sure Thyroid Gland Anatomy Hormones Problems that they have put needle in the right spot to aspirate the Thyroid Gland Anatomy Hormones Problems contents of the non-dual so they take a Thyroid Gland Anatomy Hormones Problems little sample out of the nodule and subject that sample Thyroid Gland Anatomy Hormones Problems material for the pathologist look at them Thyroid Gland Anatomy Hormones Problems under the microscope to decide what Thyroid Gland Anatomy Hormones Problems kind of non-dual it is it is good to have pathologist who Thyroid Gland Anatomy Hormones Problems has experience in seeing thyroid psychologies and they Thyroid Gland Anatomy Hormones Problems can you know describe not really their as a benign nodule Thyroid Gland Anatomy Hormones Problems where the nodule is something that is not cancerous or they may describe normal as a cancer it's not real or worrisome for cancer if it has Thyroid Gland Anatomy Hormones Problems features suggestive of cancer on the microscope in some cases even the best hands you may have reports which are indeterminate where it may not fit Thyroid Gland Anatomy Hormones Problems into the benign category nor it may fit into them in the legs in category with these reports you generally in a review back with your doctor.

The doctor then decides if you need to have a follow-up just a watchful observation with either repeat ultrasound or a repeat FNAC in six months to one year or if they're if the non-dual is worrisome one of ultrasound or the FNC report is malignant then they subject you to surgery are there any tablets or medicines for thyroid nodules unfortunately no previously there used to be a theory of giving excess Tyrod hormone to suppress the growth of the nodules unfortunate that as for that practice has fallen out of favor we don't use medicines to shrink nodules and in general the important message is that if you have a non-dual it has to be ascertained if it is a benign nodule or a cancerous non-dual to the cancer it's not doable the recommendation is to have surgery it's a benign nodule then you discuss with your doctor in terms of the benefits and risks follow-up long term with ultrasound and repeat FNAC if required.

Thyroid diseases can be divided into three major groups there is an excessive production of the thyroid hormone which is called hyperthyroidism there is decreased production of the thyroid hormone which is called hypothyroidism multiple nodules or generalized swelling of the thyroid gland is called a goiter hyperthyroidism means that the thyroid gland is producing excessive thyroid hormone it causes increased metabolism which consumes a lot of your energy it is the main reason why people having hyperthyroidism feel tired many people with hyperthyroidism are also nervous and stressed which makes them even more tired hyperthyroidism can be Treatise hyperthyroidism has many symptoms because all of the processes in the body work much faster.

Common complaints are feeling warm shortness of breath during exercise loss of strength menstrual problems weight loss increased heart rates diarrhea and psychological complaints like fear and irritability these symptoms usually do not all occur at the same time in some cases the thyroid gland might also be enlarged the most common cause of hyperthyroidism is Graves disease.

Feeling cold heart problems increased in weight depressed feelings hair loss and deeper voice and bowel problems one of the common causes of hypothyroidism is Hashimoto's disease in Hashimoto's disease there is an immune response of the body against the thyroid gland which causes decreased function of the thyroids hypothyroidism can result from treatment of hyperactive thyroids thyroid disorders can also be caused by changes in the structure or form of the thyroid in some cases the thyroid might be enlarged quiter is one of the most common thyroid problems when you have goiter the thyroid gland gets enlarged and there is visible swelling in the neck Kuta has several causes such as infection iodine deficiency benign or malignant disease a malignant disorder is extremely rare when you have goiter there can be a problem in swallowing or breathing before treating goiter the underlying cause must be determined thyroid problems can be diagnosed with blood tests and sometimes using a thyroid scan or a puncture other times thyroid swelling disappears even without treatments hypothyroidism can be treated with thyroid hormone pills depending on the cause
 hyperthyroidism can be treated with medication to reduce the production of thyroid hormone another option is treatment with radioactive iodine to stop the function of thyroid cells surgery can also treat hyperthyroidism gouta can be treated with surgery or with radioactive iodine do you have any symptoms which might indicate thyroid problems please consult your general practitioner for advice.
