Introduction
Hypothyroidism is defined by a reduction in the release of the main thyroid hormones, Thyroxine (T4) and Triiodothyronine (T3). These hormones are essential in the homeostatic maintenance in the area of metabolic function (PetMD, 2017). This condition is not life-threatening and is usually very inexpensive to treat (WebMD, 2017). While there are many causes for hypothyroidism, the common causes include shrinking of the thyroid gland, tumors or cancer of the thyroid, congenital disease, iodine deficiency, and sometimes even an autoimmune issue where the body attacks its own thyroid. The risk for this disease appears to increase when the animal is spayed or neutered for currently unknown reasons (WebMD 2016). This condition is most

The most common symptoms include unexplainable weight gain, lethargy, and inattentiveness. If the dog has been experiencing long term, unmanaged hypothyroidism then it may also demonstrate skin thickening, dry and dull hair, frequent skin infections, and cold intolerance (Andrews, 2008). Some rare symptoms may include head tilting, seizures, and infertility. If a canine exhibiting a combination of these symptoms is presented to a veterinarian, testing may be performed in order to obtain a diagnosis. A physical exam and blood panel are crucial to eliminate possible issues not pertaining to the thyroid. Some vets may be able to make a diagnosis based on these results, but often times an endocrine panel will need to be performed to test the T3 and T4 levels in order to make an accurate hypothyroidism diagnosis. Some veterinarians will diagnose the dog with this condition is it matches at least 3 symptoms and demonstrates no obvious signs of abnormalities in the physical exam and blood work in order to save the owner money (PetMD, 2017). According to Dr. Dodds, T4 should 1.60-3.80µg/dL T3 should be 35-70ng/dL in a healthy dog. In a study done by Daminet and Paradis in 2000, hypothyridic dogs had T4 levels as low as 0.26µg/dL. Due to the late manifestation of this condition, often times dogs do not exhibit any symptoms until around 4 years of age. Dogs with genetic …show more content…
As more is studied about the thyroid gland, it has become clear that iodine helps in its function and a diet lacking in it may be a significant cause of the thyroid gland malfunctioning and not producing enough hormones. Ensuring a dog’s diet contains adequate amounts of iodine will keep its thyroid active. Tyrosine intake must also be closely monitored. Since obesity is a symptom of hypothyroidism, it is important to control weight gain by switching the dog to a low calorie, low carbohydrate food (Andrews, 2017). It is important to consult a veterinarian when wanting to use a natural thyroid support product due to the fact that if these are used with the medication, it may actually cause the disease to progress instead of stopping it (Mercola,
According to The National Institute of Diabetes and Digestive and Kidney Diseases, diagnosis of Hashimoto’s thyroiditis begins with a physical exam and medical history. A goiter, nodules, or growths may be found during a physical exam, and symptoms may suggest hypothyroidism. Health care providers will then perform blood tests to confirm the diagnosis. Diagnostic blood tests may include the TSH, which, if above normal lab values, means a patient has hypothyroidism. Blood tests also include T4, which is the amount of thyroid hormone in the blood. In hypothyroidism, the blood lab values are lower than normal. The anti-thyroid antibody tests look for presence of thyroid autoantibodies. Most people with Hashimoto’s disease have these antibodies; however, hypothyroidism isn’t always caused
The author Azeez Farooki MD in “Hypothyroidism: What You Should Know about Your Treatment”, focused on the drug levothyroxine which replaces the thyroid hormone that is not being produced in the body of people with hypothyroidism. Hypothyroidism is very common and it affects more than 27 million people and mostly women and elderly. Levothyroxine is a synthetic medication and some people that take it have a more difficult time tolerating it or absorbing it the traditional way. The doctor might be able to prescribe a more natural “pure” levothyroxine formula to those people. The symptoms of hypothyroidism are very similar to many other diseases which sometimes can be overlooked and people become undiagnosed. It’s important to keep great communication with the doctor to have success in treatment. The treatment is usually a lifelong situation and the doctor
The history of hypothyroidism dates way back to the 1800s; seeing the symptoms in patients, even before the disease was able to be diagnosed. Later realizing that many of the cases of cretinism, later called hypothyroidism, were largely associated with the lack in function of the thyroid. Today, also realizing that there is not only internal factors that influence hypothyroidism but also external factors that can contribute. Hypothyroidism can present itself in many different ways from no symptoms at all to organ failure, in a severe enough case. Discovering and treating hypothyroidism with medication or alternative, if the patient chooses, can be very simple after confirming diagnosis with lab results. An optimistic prognosis is usually given to patients diagnosed with hypothyroidism.
The main treatment for hypothyroidism is synthetic thyroid hormone in pill form to replace what’s missing. Depending on the reason for the slow thyroid, adding more iodine to the diet and generally eating a healthy diet can help.
In dogs, “the two most common causes of primary hypothyroidism include lymphocytic thyroiditis and idiopathic atrophy of the thyroid gland” (Kahn 2010). Lymphocytic
The patient’s primary problem is hyperthyroidism with thyrotoxicosis with is also known as thyroid storm, which is the hyperactivity of the thyroid gland which increases the release of thyroid hormones. The pathophysiology of hyperthyroidism is when a person develops antibodies to TSH receptors which then in return it stimulates a release of T3, T4 or both which leads to thyrotoxicosis. Thyrotoxicosis is a hyper metabolism of T3, T4 or both in circulation. It is reflected in the patients clinical presentation by the significant physical findings
Hypothyroidism is a disease that affects the Thyroid Gland located in the lower part of the neck, is wrap around trachea . The Thyroid Gland looks like a butterfly, the two wings are the lobes and the middle part is called Isthmus. Hypothyroidism is disease where a person's thyroid gland does not produce enough hormones. The thyroid hormones are very important, it affects your growth, development and other cellular process. Having hypothyroidism can bring many problems to your body.
Hypothyroidism patient, needs good care and should take thyroid hormone medicine correctly. The victim need to see the doctor at least once per year, so that the doctor can check the victims condition closely and the doctor may adjust the treatment if need be. If the medicine has side effects, the doctor should be informed in order to have regular blood tests of finding whether the correct amount of thyroid hormone is being received. If left untreated and taking poor nutrition, hypothyroidism can lead to
Before understanding what hypothyroidism is it helps to know what the thyroid is and how it works. The thyroid is a gland in the lower front of the lower front of the neck just below the Adams apple. Think of it as the bodies thermostat. It impacts many parts of the body the muscles, bones, skin, heart, brain, liver, kidneys, digestive tract, and more. Millions of people have hypothyroidism and many or undiagnosed. Both women and men can develop hypothyroidism, but it is more common among women. In fact, women are five times more likely than men to suffer from hypothyroidism. Hypothyroidism is a lifelong condition that can occur at any age. Your body gives you signals that something is wrong the way your body normal feels. This tells you the you need to go to see a doctor to explain your symptoms with him or her. This will give you a better or closer look to see what is causing this issue or change that you notice in your body. You will probably have to have test done to assist them in diagnosing your issue.
The thyroid is a butterfly shaped gland that is located in the front of your neck. This glands purpose is to act as the control center for your body and secrete hormones that help sustain the organs. Two conditions that can affect the thyroid to become overactive or underactive are called hyperthyroidism and hypothyroidism. The main difference between hyperthyroidism and hypothyroidism is the thyroid’s hormone production. Hyperthyroidism is a disorder where your thyroid gland creates too much of the hormone thyroxine and this is known as throtoxicosis. Thyroxine is the primary hormone secreted into the bloodstream and is vital in heart and digestive functions, regulating metabolic rate, and maintaining bone, just to name a few. Hyperthyroidism
There are diseases in which an animal’s body does not function properly. Companion animals whose body produce excess amounts of thyroxin (T3 & T4), a thyroid hormone from the thyroid gland, is diagnosed with Hyperthyroidism, also called thyrotoxicosis. This disease is not recognized in livestock like in companion pets. Felines who are adult age are the companion animal designated to contract this disease. Canine’s thyroid composition can handle and dispose of any excessive hormone surplus, so hyperthyroidism symptoms only occur when a tumor is present. Each species of animal has its own anatomical thyroid gland. In general, non-cancerous adenomas are known to enlarge thyroid glands, whereas thyroid adenocarcinomas also enlarge the gland, but
The 19th and 20th century brought great medical understanding to the thyroid gland. The thyroid was once though to lubricate the larynx; but during this time doctors began to understand the importance of the thyroid (Hamdy). According to the American thyroid association, Thomas Warton named the thyroid in 1656; due to a resemblance the gland had with a Greek shield. It wasn’t until 1850 the first case of hypothyroidism was finally described. Hypothyroidism is a condition in which the thyroid gland production of the thyroid hormone is abnormally low. The purpose of the thyroid hormone, which is secreted by the thyroid, is to maintain the metabolism throughout the body.
Binding of TSH to thyroid gland receptors leads to release of thyroid hormones, when there are elevated levels of these hormones there is a reaction that occurs to the hypothalamus that signals it to decrease TRH secretion and therefore synthesis of TSH begins (Lee 2015). Iodine is required for the synthesis of thyroid hormone. “Inorganic iodide is transported into the gland by an iodide transporter, convert to iodine, bound to thyroglobulin by the enzyme thyroid peroxidase, all which is a process known as Organification” (Lee 2015). The outcome of the Organification process is the formation of MIT and DIT which help with the formation of T-3 and T-4 hormones, which is then kept with the thyroglobulin in the thyroids follicular lumen. Any disturbance of the regulated mechanism can arise in the pituitary, thyroid or periphery glands and can result in an increase in the transcription in cellular proteins which causes a rise in basal metabolic
During an exam, a person’s doctor may try to detect a slight tremor in your fingers when they're extended, overactive reflexes, eye changes and warm, moist skin. Your doctor will also examine your thyroid gland as you swallow to see if it's enlarged, bumpy or tender and check your pulse to see if it's rapid. (Mayo Clinic, 2015). “A diagnosis can be confirmed with blood tests that measure the levels of thyroxine and TSH in your blood. High levels of thyroxine and low or nonexistent amounts of TSH indicate an overactive thyroid. The amount of TSH is important because it's the hormone that signals your thyroid gland to produce more thyroxine. These tests are particularly necessary for older adults, who may not have classic symptoms of hyperthyroidism.” (Mayo Clinic, 2015, pg. 2) “Your doctor may also want to obtain a picture of your thyroid (a thyroid scan). The scan will find out if your entire thyroid gland is overactive or whether you have a toxic nodular goiter or thyroiditis (thyroid inflammation). A test that measures the ability of the gland to collect iodine (a thyroid uptake) may be done at the same time.” (ATA, 2018, pg. 1) Hyperthyroidism can be treated by antithyroid drugs, radioactive iodine, surgery, or beta
Iodine supplements for hypothyroid as well enhance iodine caused thyroid problems. Generally, you need to consume food full of vitamin B, Iron, Antioxidants and get away from Soy, alcohol and also tobacco.
