Hypothyroidism Impact on Public Health
The thyroid organ, though small, impacts every cell in the body by providing metabolism regulation (endocrine web). This butterfly-shaped, endocrine organ located at the neck, secretes hormones to control the body’s metabolism - or the way the body uses energy that help the body with energy, manage heat, and help organs such as the heart and brain function properly (thyroid.org). When not functioning properly, thyroid dysfunctions occur disrupting the three points of control: the hypothalamus in the brain, the pituitary gland, and the thyroid gland. Common thyroid disorders include Hashimoto’s, Graves’ disease, thyroid disorders like hypothyroidism and hyperthyroidism, and nodules or goiters (health line).
The focus of this paper will be hypothyroidism. Hypothyroidism

T). When thyroid genes are acting as they are designed, they ramp up the mitochondria to work at optimal capacity. However, mitochondria the power plants of the cell, are unable to work in converting fat and oxygen into chemical energy, homeostasis is disrupted.
Because the body, namely the “brain, heart, liver, kidneys, pancreas, and skeletal muscle, demand a finely tuned capacity for energy and lots of it, these tissues possess more mitochondria” (parkridge). When the mitochondria are not properly functioning for these organs, cell damage can occur.
One needs to recognize the combination of physical signs (thinning hair, thick tongue, excess weight, etc.) and common symptoms (fatigue, difficulty concentrating, cold intolerance, etc.).
Additional Hashimoto’s
The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes its way to the bloodstream until it reaches the thyroid where it is then signaled to activate T3 and T4 production [1]. This mechanism is controlled by a negative feedback loop meaning that when there is a sufficient amount of thyroid hormones in the blood stream, this will signal back to stop production of thyroid stimulating hormones. Complications occur when the thyroid hormones keep increasing even though there is already a sufficient amount of T3 and T4 in the blood stream. This process of over expression of thryroid hormones is known as hyperthyroidism. Hyperthyroidism is a general term that includes any disease that has a consequence of an overabundance of thyroid hormones. Hyperthyroidism is a general term but there are many variant diseases that are in the hyperthyroidism category. These diseases include diffuse toxic goiter, Basedow’s disease, thyrotoxicosis, Parry’s and Graves’ disease.
Mitochondrion is defined as a spherical or rod-shaped organelle that is found within the cytoplasm of the eukaryotic cells, and they are responsible for the production of energy such as ATP, which is needed for cellular processes. Mitochondria is important to eukaryotic cells. They can reduce fatty acids and other lipids, and lengthening chains of fatty acids. The subunits of membrane bound hemeproteins are synthesized and assembled in the mitochondria. Mitochondria is capable of growing or rapidly producing independently within the cell. It has been found that mitochondria contains genetic apparatus for synthesizing enzymes and proteins.
The mitochondria produces food for the cell by converting energy the cell needs. The mitochondria and the nucleus are two organelles within a cell that have many of the same similarities. Both organelles are made of two membranes. These layers isolate within the organelle all things considered, yet have protein channels that permit things to go in and out. Both contain DNA material that conveys qualities that encode for proteins. Both have qualities that make ribosomes, the machines that read the guidelines in RNA to make
The organelle responsible for energy production in the cell is the mitochondria. Eukaryotic cells contain or have mitochondria. For the body to function all humans have mitochondria which makes living possible.
Because the mitochondria is like the motor because they both are the power house. Which they keep the cart or cell active or running. Wow Timmy you know a lot about cells already.
There are two pairs of parathyroid glands, one on each side of the thyroid. Hormones secreted from these glands regulate calcium levels in blood and bone metabolism. The thyroid gland is located in the lower, front part of the neck. Thyroid hormones also regulate metabolism, as well as bone growth and development in children. Additionally, they maintain normal blood pressure, heart rate, digestion, muscle tone, and reproductive glands. The release of these hormones are controlled by pituitary glands.
When the hypothalamus secretes thyrotropin releasing hormone, which then stimulates the anterior pituitary gland to release thyroid-stimulating hormone. The thyroid-stimulating hormone stimulates the thyroid gland to release its hormones T3 and T4. The hormones regulate general body metabolism. An imbalance within the thyroid hormones may interfere with the following body functions: growth, maturation; carbohydrates, proteins, and lipid metabolism; thermoregulation; cardiovascular function; and reproduction. Thyroid disease is broken up into two opposite disorders such as: hypothyroidism and hyperthyroidism. This happens when your thyroid gland is not functioning
The doctors used to replace the thyroid hormone for the people who suffered from the hypothyroidism. They followed this procedure for several years. Hashimoto’s thyroiditis is the condition which we can observe in the thyroid diseases. This is the condition where we cannot observe any symptoms, by the way it’s very difficult to diagnose the disease. We can able to diagnose the disease by microscope examination. It is very difficult process and can’t perform all the time. This disease destroys thyroid gland. It is very difficult to regulate the condition, so doctors used to replace thyroid gland. They also used Cytomel or Synthroid instead of T3 and T4 for the treatment of thyroid disease. Cytomel, Synthroid, T3, and T4 are the main hormones which are used for thyroid treatment. Natural thyroid preparations include thyroid extracts which contain both T3 and T4, this are the first treatment which are available in the market. Several dosages were adjusted to solve this problem. They performed many clinical trials for the thyroid treatment. They observed the development of serum TSH and identification of peripheral deiodinase mediator conversion of T4 to T3. L-Thyroxine mono therapy treatment also used for the treatment of hypothyroidism, but after many clinical trials they came to know that this therapy has several side effects, so they did not used this
Hypothyroidism is caused by a lack of production of the metabolism-regulating hormone thyroxine by the animal’s thyroid gland. The thyroid gland is located in a dog or cat’s neck and is responsible for producing many of the hormones used in various chemical processes in the body, including the regulation of metabolism and other cellular processes. The thyroid’s output is usually dictated by signals from the “master gland,” the pituitary. But despite the signals received from the pituitary the thyroid, in an affected animal, cannot produce the desired amount of the hormone
The use of energy in animal cells follows the basic laws of thermodynamics. This implies that energy that the energy utilized in the biological systems cannot be created or destroyed. In addition, the process of conversion of energy from a given form to another is never 100 %, which means that part of the energy gets lost (Clark,
There are many enzyme-catalyzed reactions that occur in cells through control mechanisms, which keep humans in chemical balance. There are two systems that have a major responsibility for regulating body chemistry known as the endocrine system and nervous system. The endocrine system depends on chemical messengers that flow in the bloodstream known as hormones. Hormones travel to target cells, where they connect with receptors that initiate chemical changes within cells. The nervous system depends on neurotransmitters that are electrical impulses in nerve cells activated by its own chemical messengers. The nervous system counts on a much faster means of circulation. This cycle is what allows drugs to work so well, because they mimic the crucial role of hormones and neurotransmitters in the function of the human body.
Hormones are chemical messengers produced by glands and are distributed through the body from the bloodstream to affect different parts of the body based on which hormone fits with which receptor and target cells. Hypothalamus is a part of the brain responsible for the direct control of the endocrine system through the Pituitary Gland. The Pituitary Gland is a small lump of tissue connected to the hypothalamus surrounded by blood vessels which carry the released hormones throughout the body. Another gland in the endocrine system is the Thyroid gland, this regulates your metabolism (ability to break down food) by releasing thyroid hormones into the bloodstream. The pituitary gland and the hypothalamus control the thyroid by watching its hormone levels. If the hormone levels drop the hypothalamus secretes a hormone which alerts the pituitary gland and informs it to produce thyroid stimulating hormones, which allows the thyroid to produce more hormones. The endocrine system uses feedback mechanisms in order to control
Hyperthyroidism: Hyperthyroidism is a condition caused by overproduction of thyroid hormone. The common cause of hyperthyroidism includes, Graves’ disease, toxic adenoma and toxic multinodular goiter. Graves’ disease is the common cause of hyperthyroidism in the United States. Adrenergic symptoms such as palpitations, tachycardia, tremor, anxiety, jitteriness, heat intolerance, diaphoresis, stare, lid lag, and hyperdefecation are the most common manifestations of hyperthyroidism. Hypermetabolism causes weight loss despite an increased appetite. Neuromuscular symptoms includes, weakness of proximal muscles. Whereas psychiatric symptoms consists of anxiety, insomnia and
Everyone has one unique characteristic about them. Some are hobbies, others are weird Interests and even physical features can make a person special—in a good way. Being different is everyday life for all of us. Being excluded from certain things. Being looked upon as different due to one’s personal mind set and beliefs sets someone apart. Getting judged on your appearance and other traits, these are common behaviors in today’s world. However, it’s against the opinion of many who say humans should be judged by what’s on the inside rather than what’s on the outside. From race and religion to what kind of car you drive are all things that make people unique. One’s personal choices should not influence the way that others look upon you as a person. From race and religion to what kind of car you
Although hormones circulate throughout the body, each type of hormone influences only certain organs and tissues. Some hormones affect only one or two organs, whereas others have influence throughout the body. For example, thyroid-stimulating hormone, produced in the pituitary gland, affects only the thyroid gland. In contrast, thyroid hormone, produced in the thyroid gland, affects cells throughout the body and is involved in such important functions as regulating growth of cells, controlling the heart rate, and affecting the speed at which calories are burned.Insulin , secreted by the islet cells of the pancreas, affects the processing (metabolism) of glucose, protein, and fat throughout the body. Most hormones are proteins. Others are steroids, which are fatty substances derived from
