When you talk about your thyroid, most people know that it is a gland located somewhere in our throats. You may also know that it is a gland that secretes a hormone that is quite powerful. You may also be aware that some people have certain thyroid disorders for which they need regular medication. However, you may not know that over 42 million people suffer from thyroid-related diseases in India. Doctors and scientists suggest that this number will only increase in the coming years. The thyroid needs to be taken care of and treated in time; otherwise, a person could develop thyroid cancer and other diseases that could lead to death.

Keeping all of this in mind, let us look into thyroid and its causes and effects.

What is Thyroid?

A tiny gland called the thyroid can be found close to the base of your neck, which wraps itself around the trachea. It has two wing-like structures that go around the sides of your throat and is fashioned resembling a butterfly with a small centre. Your body has glands that help produce and release compounds that assist in various physical processes. Your thyroid creates hormones that aid in handling several essential bodily operations.

The two thyroid chambers on either side of the glands are connected by an extremely thin region of tissue called the isthmus. The thyroid uses iodine for the production of essential hormones. The most important hormone that is created by the gland is called thyroxine, which is also popularly known as T4. A small amount of the T4 produced in the gland is metabolised to triiodothyronine (T3), the most potent hormone, before being transported via the circulatory system to the body's organs and tissues.

A brain-based feedback process controls the thyroid gland's operation. Thyrotropin-releasing hormone (TRH), produced by the brain's hypothalamus if thyroid hormone concentrations are low, prompts the pituitary gland, which is situated at the underside of the brain, to create the thyroid-stimulating hormone (TSH). TSH enables the thyroid to make more T4.

Since the pituitary glands and hypothalamus regulate the thyroid gland, diseases of these organs can also impair thyroid function and result in thyroid difficulties.

Types of Thyroid

Unless a person knows what kind of thyroid they suffer from, it becomes impossible to treat it. And as already determined above, if thyroid is not diagnosed in time and treated efficiently, it can cause many problems for the patient. The treatment and care you receive for your thyroid-related problems will depend on the kind of thyroid you have. In general parlance, there are two basic types of thyroid. These are called hypothyroidism and hyperthyroidism.

  • Hypothyroidism- The thyroid gland's inability to produce enough thyroid hormone leads to hypothyroidism. It may be brought on by thyroid, pituitary glands, or brain issues.

  • Hyperthyroidism- In contrast to hypothyroidism, hyperthyroidism refers to the overproduction of thyroid hormones. Hyperthyroid disease symptoms frequently involve a slower metabolism. A patient might not notice any hyperthyroidism symptoms if the case is very mild. There are three basic types of hyperthyroidism that a person may suffer from. They are Graves Disease, Thyroiditis and Toxic nodular goitre.

In more severe cases, your thyroid may become:

  • Goitre- Notwithstanding the reason, swelling of your thyroid is generally referred to as a goitre. A goitre itself is not a particular illness. Hypothyroidism, hyperthyroidism, or regular thyroid function can all be linked to a goitre.

  • Thyroid Cancer- Adult women are much more likely to develop thyroid cancer than men or children. About two-thirds of instances affect adults under 55. Based on the particular cell form that has developed into a tumour, there are various types of thyroid cancer. When detected promptly, thyroid cancer often has a favourable prognosis and actual survival.

Now that you have a general idea of thyroid and its various types, let us look into hyperthyroidism and its causes a little more deeply.

Hyperthyroidism Causes

Knowing your hyperthyroidism causes can help you understand your disease better. Understanding the disease helps you take care of yourself and your needs better. It also aids you in helping your doctor in making a diagnosis. Here is what you need to know about hyperthyroidism causes.

Several circumstances can bring on hyperthyroidism. The most typical hyperthyroidism cause is the autoimmune illness Graves' disease. In Graves' disease, the thyroid gland is invaded by antibodies produced by your immune system, which causes an excessive amount of hormone to be released.

Women experience Graves' illness more frequently than males do. According to a 2011 scientific overview, environmental factors also impact whether someone may develop Graves, but genetics still play a significant influence. Graves' illness isn't caused by a solitary gene deficiency but by tiny mutations in several genes. For your doctor to accurately assess your risk factors, you should let them know if any members of your family have been given a hyperthyroidism diagnosis.

Other causes of hyperthyroidism, outside Graves' disease, include:

  • Thyroid Nodules- Nodules in the thyroid gland known as thyroid nodules are lumps or cellular growths. Your body may absorb more hormones from them than it requires. However, there are very few cases where these nodules are malignant.

  • Thyroiditis: A swelling of the thyroid gland that may or may not be painful is known as thyroiditis. In many cases, thyroiditis occurs within a year of a woman giving birth to a baby, called postpartum thyroiditis. Your thyroid may not be able to recover from thyroiditis, which might result in hypothyroidism.

  • Excess Iodine Consumption: If you are someone who is consuming too much iodine, either through your food or prescription drugs, your thyroid may generate extra thyroid hormone. Your thyroid uses the mineral iodine to produce thyroid hormone. Hyperthyroidism may also result from getting IV iodinated contrast. Amiodarone, a drug with a high iodine content, can also result in hyperthyroidism.

  • Excess T4- If you have a large amount of T4 in your blood, it could lead to hyperthyroidism.

Barring these, there are some risk factors when it comes to hyperthyroidism. These risk factors include;

  • If someone in your family has had hyperthyroidism, it is possible that you too will have hyperthyroidism.

  • Pregnancy can sometimes stimulate hyperthyroidism in a mother.

  • Some diseases like diabetes and adrenal gland diseases can sometimes lead to the development of hyperthyroidism.

  • People over 55 are at a greater risk of developing hyperthyroidism.

  • Females are more likely to develop hyperthyroid disease than males.

  • If you are diagnosed with tumours in your ovaries or testes, you are at a greater risk of developing hyperthyroid syndrome.

Hyperthyroid Disease Symptoms

Knowing the symptoms of any disease is very important because, in many cases, understanding your disease's symptoms can help your doctor determine how to help you. Knowing your symptoms can also help you understand when to approach your doctor and get help. Since getting treatment before the disease progresses is important, knowing your symptoms is extremely important and helpful.

Some symptoms to be on the lookout for if you suspect you have hyperthyroid disease include;

  • Heart palpitations (pulse over 100 beats per minute)

  • Changes in menstrual patterns

  • Loss of weight, but an increase in appetite

  • Nausea

  • Sleep apnea

  • Anxiety

  • Tremors in the limbs

  • Exhaustion

  • Irritated Bowel Syndrome

  • Increased sweating and severe overheating

  • Trouble with vision

  • Change in the texture of skin and hair

  • Weakness in the muscles

  • Swelling in the neck

  • Bulging of the eyes

  • Light sensitivity

  • Sudden bouts of extreme irritability

Effects of Hyperthyroidism

Like any other disease, if hyperthyroidism does not receive the right care and treatment in time, it could develop into a more serious form of the disease. This is why understanding your disease and going to the doctor to get help at the right time are of paramount importance. It could sometimes even be the difference between life and death.

In some cases, when hyperthyroidism does not get the care required to stay under control, it could evolve into a more severe form of the disease. Some effects of hyperthyroidism, if left untreated or diagnosed at a later stage, include:

  • Osteoporosis - Your bones may become thin and brittle due to hyperthyroidism, which may result in osteoporosis. Bone health can be enhanced by consuming calcium and vitamin D medications post-treatment. Regular physical activity and getting enough exercise also assists prevent osteoporosis.

  • Complications During Pregnancy- This covers those who already have thyroid conditions and those with hyperthyroidism while pregnant. Both pregnant women and the foetus can suffer from high thyroid hormone levels. Preterm birth and miscarriage are risks that should be kept in mind. Frequent thyroid hormone checks can spot anomalies during pregnancy, and the physician may decide the right course of treatment.

  • Thyroid Storm- When the thyroid is left untreated, it can lead to a rare medical disorder known as a thyroid storm. Too excess thyroid hormones in your body cause it to go into overdrive. Thyroid storm is an amalgamation of symptoms that can be fatal, comprising fever, elevated blood pressure, and a rapid heartbeat.

  • Cancer - Thyroid carcinoma, a thyroid cancer, can develop in some hyperthyroid patients. According to medical professionals and researchers, thyroid cancer in people with hyperthyroidism is more "aggressive" and has a poorer prognosis compared to people with euthyroidism (healthy thyroid).

Now that we have seen the effects of hyperthyroidism let us learn how to diagnose the disease.

Hyperthyroidism Disease Diagnosis

When a doctor is making diagnoses related to hyperthyroidism, they will always begin by asking you about your medical history and the symptoms you are experiencing. In many cases, your doctor will have a fair idea about your case by hearing your symptoms alone. They might also look for physical signs related to hyperthyroidism, like swelling in the neck or bulging eyes, as well as the texture of your skin. Your doctor can also make a more successful diagnosis if you provide them with important information about your family's medical history, in this case, if anyone in your family has been suffering or has suffered from hyperthyroidism.

Keeping all of this in mind, your doctor may ask you to undergo a few tests, including;

  • Free T4, T4 and T3 level tests- These examinations evaluate your blood's level of thyroid hormones (T4 and T3).

  • TSH (thyroid stimulating hormone) Level Assessment- TSH is a hormone produced by the pituitary gland that prompts the thyroid to generate hormones. Your pituitary gland reacts to elevated thyroid hormone amounts by producing less TSH. TSH levels that are excessively low can be a warning sign of hyperthyroidism.

  • Ultrasound of the Thyroid- The thyroid gland's overall size and any tumours present can be determined using ultrasound technology. The solidity or cystic nature of a mass can also be determined by doctors using ultrasounds.

  • MRI or CT scans- If a pituitary tumour is present, a Computed tomography (CT) or MRI can demonstrate this.

  • RAIU Test- The Radioactive Iodine Uptake test measures how much radiotracer your thyroid receives through oral administration of a modest, safe dosage. Your doctor will use a gamma sensor to examine your neck after a set period to determine the quantity of radioactive iodine the thyroid has collected, often between 6 and 24 hours. If your thyroid has absorbed a significant amount of radioactive iodine, it indicates that your thyroid is making excessive thyroxine. If so, you most certainly have thyroid nodules or Graves' disease.

  • Thyroid scan- This process is an expansion of the RAIU in which you will lie on a bed with your neck inclined back, and a special camera (a gamma camera) will take numerous photos of your thyroid in addition to monitoring the radioactivity accumulated by your thyroid. Due to the radioactive particles, your thyroid may seem completely "bright" on the screen or only in some areas. Your doctor may use a thyroid scan to check for thyroid lumps or nodules, inflammation, swelling, goitre, or thyroid cancer.

Hyperthyroidism Treatment

If you are wondering what hyperthyroidism treatment path your doctor will take to control your symptoms, there are several paths to choose from. Your doctor will draw a treatment plan based on the severity of your case and your symptoms.

Some hyperthyroidism treatment plans include;

  • Medication- Propylthiouracil (PTU) and methimazole (Tapazole) prevent your thyroid from producing an excess of hormones. These medications will usually reduce your discomfort in a few days or weeks, but you may need to continue taking the medicines for approximately 18 months to reduce the likelihood of a resurgence of symptoms substantially. Because of its milder side effects, methimazole is more frequently recommended. Allergic responses like redness or itching are examples of side effects of the drugs. Up to 3% of persons taking antithyroid drugs may experience allergic reactions.

  • Radioactive Iodine- Your hyperactive thyroid cells assimilate radioactive iodine, which is an oral medication. Over a few weeks, the radioactive iodine destroys these cells, shrinks your thyroid, and lowers your thyroid hormone levels. In most cases, this results in the thyroid being permanently destroyed, curing hyperthyroidism. This drug uses a different dosage of radiation than the RAIU test and scan needed to make a diagnosis. To keep their hormone levels balanced, most patients who undergo this procedure must consume thyroid hormone medications for the remainder of their lives.

  • Surgery- Your doctor might extract the whole or a portion of your thyroid if medicines aren't a viable solution for you. The term for this surgery is a thyroidectomy. To avoid difficulties, you may be required to take antithyroid medications before surgery. You can then develop hypothyroidism and require a hormone supplement. You might require medicines to maintain the calcium concentrations in your bloodstream where they ought to be if your doctor is also removing your parathyroid glands.

  • Use of Beta Blockers- These medications prevent the body from being affected by thyroid hormones. They do not alter the hormone levels in your bloodstream, but they might help manage hyperthyroidism-related symptoms such as rapid pulse, anxiety, and instability. Long-term management of hyperthyroidism typically involves combining this medication with another approach rather than using it alone.

Hyperthyroid Syndrome Prevention

There are no sure ways to guarantee that something will or will not prevent the onset of hyperthyroidism in a person. However, you can take a few preventive methods that may help you in the long run. These preventive methods include;

  • Regular screening for thyroid

  • Quit smoking

  • Get checked for celiac disease

  • Ask for a thyroid collar when getting an X-ray

  • Check your neck for swelling

  • Know the symptoms of hyperthyroidism and go to your doctor immediately if you notice any symptoms
