Correcting The Estrogen Dominance

What Causes a Goiter? Iodine Deficiency & Thyroid Nodules Dr.Berg

After the thyroid gland has normalized, we can continue the progesterone and Vitamin E to help correct the underlying estrogen dominance.

Youre helping to protect your thyroid and prevent the future development of goiters and nodules too.

And keep in mind that regulating estrogen also applies to the prevention of goiters and nodules too.

You can never be too safe with your thyroid health.

If you have a goiter or thyroid nodules, then you can use these same steps that we use to help our clients too.

How Is Thyroid Cancer Managed Or Treated

Treatments for thyroid cancer depend on the tumor size and whether the cancer has spread. Treatments include:

  • Surgery: Surgery is the most common treatment for thyroid cancer. Depending on the tumors size and location, your surgeon may remove part of the thyroid gland or all of the gland . Your surgeon also removes any nearby lymph nodes where cancer cells have spread.
  • Radioiodine therapy: With radioiodine therapy, you swallow a pill or liquid containing a higher dose of radioactive iodine than whats used in a diagnostic radioiodine scan. The radioiodine shrinks and destroys the diseased thyroid gland along with cancer cells. Dont be alarmed this treatment is very safe. Your thyroid gland absorbs almost all of the radioiodine. The rest of your body has minimal radiation exposure.
  • Radiation therapy: Radiation kills cancer cells and stops them from growing. External radiation therapy uses a machine to deliver strong beams of energy directly to the tumor site. Internal radiation therapy involves placing radioactive seeds in or around the tumor.
  • Chemotherapy: Intravenous or oral chemotherapy drugs kill cancer cells and stops cancer growth. Very few patients diagnosed with thyroid cancer will ever need chemotherapy.
  • Hormone therapy: This treatment blocks the release of hormones that can cause cancer to spread or come back.

What Are The Different Types Of Goiter

Thyroid goiters refer to enlargement or swelling of, as well as growths on, the thyroid gland. These swellings can be broken into different types based on the cause of and the shape. The main types are simple endemic, simple sporadic, toxic, myxedema, congenital, and thyroid cancer. These swellings typically develop as either a diffuse goiter with uniform thyroid gland enlargement or as a nodular goiter with asymmetric lumps forming on the thyroid. Most of these are small and are only discovered through a physical exam, but if an enlarged thyroid gland is left untreated, it can swell and protrude from the neck.

A non-cancerous enlargement of the thyroid gland is called a simple goiter and can form as a diffuse or as a nodular goiter. Simple goiters come in two sub-types, endemic and sporadic. An endemic goiter, also sometimes referred to as a colloid goiter, is cause by an iodine-deficient diet. Iodine is used in the production of thyroid hormone and when there is a dearth of iodine, the thyroid gland becomes enlarged to off-set the decreased production of thyroid hormone. Sporadic thyroid enlargement, also known as nontoxic goiters, are caused by certain drugs, regularly consuming anti-thyroid substances, genetics, or the cause can be unknown.

What Is The Thyroid Gland

Your thyroid gland is one of many glands that make up your endocrine system. Endocrine glands release hormones that control different bodily functions.

The pituitary gland in your brain controls your thyroid gland and other endocrine glands. It releases thyroid-stimulating hormone . As the name suggests, TSH stimulates your thyroid gland to produce thyroid hormone.

Your thyroid needs iodine, a mineral, to make these hormones. Iodine-rich foods include cod, tuna, dairy products, whole-grain bread and iodized salt.

Summary Of Thyroid Vs Goiter

A Comprehensive Guide To Goitrogens and Hashimoto
  • The thyroid is an endocrine gland that is found in the neck region.
  • A goiter is an unusual swelling of the thyroid due to some disease process or a deficiency of iodine in the diet.
  • The activity of the thyroid gland is naturally controlled by hormones produced by the hypothalamus and the pituitary gland.
  • The size of a goiter can be controlled by various medical interventions such as surgery or by using radioactive iodine.

Thyroid Goiter: When Is A Radioiodine Scan Ordered

If you have a thyroid goiter and your blood tests also demonstrate that your thyroid hormone level is too high , this is the only instance that a radioiodine scan is indicated. In these cases, the thyroid stimulating hormone will be very low and in cases of Grave’s disease, the thyroid stimulating immunoglobulin will be very high. The thyroid goiter patient may or may not have recognized symptoms of their hyperthyroidism.

During the thyroid scan, the patient will be given a small amount of radioactive iodine in a pill and a special imaging camera is utilized to determine how much iodine is taken up by the thyroid gland and if the thyroid goiter takes up iodine throughout the thyroid gland or whether there is a single “hot” area in the thyroid , relative to the remainder of the thyroid gland . If a thyroid nodule has less iodine uptake than the rest of the thyroid gland, then the thyroid nodule is called a “cold nodule”. In patients with multinodular goiter, frequently several of the nodules of the thyroid will be cystic and filled with fluid. These cystic areas of a multinodular goiter are expected to take up less iodine than the rest of the gland and appear “cold”.

Hot nodules are almost always non-cancerous but the preferred management of hot nodules is frequently surgery since it is a clear, safe and 100% effective therapy for the hyperthyroidism.

Toxic Nodular Or Multinodular Goiter

This type of goiter forms one or more small nodules as it enlarges. The nodules produce their own thyroid hormone, causing hyperthyroidism. It generally forms as an extension of a simple goiter.

You may be at risk for a goiter if you:

  • Have a family history of thyroid cancer, nodules, and other problems that affect the thyroid.
  • Dont get enough iodine in your diet.
  • Have a condition that decreases the iodine in your body.
  • Are female. Women have a higher risk for goiter than men.

Your doctor will check for neck for swelling. Theyll also order a number of diagnostic tests that include these below:

Deterrence And Patient Education

A sufficient daily intake of iodine is needed to prevent goiter. The recommended daily intake of iodine is 90 µg/day for children aged 2;to 5 years, 120 µg/day for children aged 6;to 9 years, and 150 µg/day for children from 10 years of age, adolescents, and adults. In pregnancy, the RDI is 250 µg/day and for lactating women, an extra 50 µg/day is recommended to provide sufficient iodine in breast milk.

Avoiding goitrogens and radiation exposure are other ways one could prevent goiter.

What Do You Do When Your Child Has A Thyroid Nodule

What are some of the risks of having a goiter?

The first step if your child has a thyroid nodule is to get an ultrasound. This will help your healthcare provider assess the quality of your childs nodule and determine if additional workup is needed. In some cases a repeat ultrasound is needed, and in some cases a biopsy. This all depends on what it looks like on the ultrasound. Some nodules require labs to look at how the thyroid is functioning.

Goiter Causes Symptoms And Treatment

A goiter is an enlarged thyroid gland. The thyroid is the gland in front of the neck just below the area of the Adams apple. This butterfly-shaped gland plays a critical role in regulating the metabolic processes of the body by producing thyroid hormone. Heart rate, blood pressure, growth, and breathing are examples of the many processes that depend upon thyroid hormone from the thyroid gland. When the gland becomes enlarged due to diseases or tumors, the gland is referred to as a goiter.

A goiter can develop as a result of numerous different conditions. It can be associated with over-function of the thyroid gland or with under-function of the gland . Also, some goiters are associated with normal levels of thyroid hormones. Both inflammation and tumors can cause thyroid enlargement. Sometimes, the entire gland may be enlarged in a symmetrical pattern, while in other goiters,;nodules, or enlargement may develop in one part of the gland only.

When a goiter becomes very large, it can sometimes cause symptoms because it presses on adjacent structures such as the esophagus and trachea. Symptoms that can occur related to a large goiter include;problems with swallowing, shortness of breath,;hoarseness, and stridor .

Some of the conditions that can cause a goiter include:

What Questions Should I Ask My Doctor

Thyroid Nodules: What Are Thyroid Nodules?

If you have thyroid cancer, you may want to ask your healthcare provider:

  • Why did I get thyroid cancer?
  • What type of thyroid cancer do I have?
  • Has the cancer spread outside of the thyroid gland?
  • What is the best treatment for this type of thyroid cancer?
  • What are the treatment risks and side effects?
  • Will I need thyroid replacement hormone therapy?
  • Is my family at risk for developing this type of thyroid cancer? If so, should we get genetic tests?
  • Can I get thyroid cancer again?
  • Am I at risk for other types of cancer?
  • What type of follow-up care do I need after treatment?
  • Should I look out for signs of complications?

A note from Cleveland Clinic

Receiving a cancer diagnosis is unsettling, regardless of the type. Fortunately, most thyroid cancers respond extremely well to treatment. Your healthcare provider can discuss the best treatment option for the type of thyroid cancer you have. After treatment, you may need to take synthetic thyroid hormones for life. These hormones support vital body functions. They usually dont cause any significant side effects, but youll have regular checkups to monitor your health.

Goiter & Thyroid Nodules

Enlargement of the thyroid and lumps within it are both relatively common.;;They may be obvious to the naked eye;or;can;be found incidentally by imaging studies of the neck, such as a sonogram of the carotid arteries or a CT or MR of the spine.;Most goiters and thyroid nodules will not interfere with a person’s health.

How Do I Know If I Have Thyroid Nodules

Most thyroid nodules do not produce any symptoms. However, if you have several nodules, or large nodules, you may be able to see them. Although rare, nodules can press against other structures in the neck and cause symptoms, including:

Hyperfunctioning thyroid nodules can lead to overproduction of thyroid hormones, also known as hyperthyroidism. Symptoms of hyperthyroidism include:

  • Irritability/nervousness

What Causes Thyroid Nodules

The most common cause of a thyroid nodule in kids is actually a “pseudonodule” or “fake nodule.” This is when inflammation of the gland makes the thyroid swell in one place. This inflammation might look like a nodule, but there isn’t really any nodule at all.

The next most common type of thyroid nodule is a cyst, which usually happens when normal fluid pockets in the thyroid get bigger. These types of nodules are always benign , but may continue to grow over time.

Thyroid nodules that are due to growths are common in adults but less common in kids. Most thyroid nodules are benign and doctors don’t always know why they happen.

Kids and teens with Hashimoto’s thyroiditis have a higher risk of thyroid nodules. As with goiters, a lack of iodine can cause thyroid nodules.

What Does A Thyroid Fine Needle Aspiration Or Biopsy Entail

In some situations this is performed with local anesthesia in the clinic. Your child will be awake. In very young children the FNA is done in the operating room under general anesthesia. The pathologist will look at the tissue to determine what they thyroid nodule is composed of and if additional workup or surgery is needed. It often takes about one to two weeks to get the results.

How Is A Thyroid Biopsy Performed Are You Awake For A Thyroid Biopsy

Thyroid biopsy is a minimally invasive procedure and is often done in the office setting. Patients are awake for the procedure.

A thin needle is carefully inserted into the thyroid nodule. The needles we use are as small, or smaller, than the needles used to draw blood. Most of the time, we use ultrasound to locate the tip of the needle. The thyroid cells that become trapped inside the needle are analyzed under a microscope. At many of our sites, we examine the cells right away to ensure we have enough material for an accurate diagnosis. A single nodule may need several samples taken to have enough cells for examination. At UCLA, we always save an extra sample for molecular testing, if needed.

After the biopsy we place a small band-aid at the needle site.;

What Are Thyroid Nodules

Goiter

A thyroid nodule is an unusual growth of thyroid cells in the thyroid gland.

The thyroid is part of the endocrine system, which is made up of glands that secrete various hormones into the bloodstream. The thyroid is a butterfly-shaped organ that is located on the front of the neck, just under the Adam’s apple . The thyroid gland, which is made up of the right and left lobes connected to the isthmus , produces and releases thyroid hormones. Thyroid hormones control functions such as body temperature, digestion and heart functions.

Advantages Of Needle Aspiration Biopsy

  • The results of needle biopsy of the thyroid are close to 95% accurate for adequate biopsies.
  • Needle biopsy is a reliable method of obtaining tissue samples that can help diagnose whether a nodule is benign or malignant.
  • A needle biopsy is less invasive than open and closed surgical biopsies, both of which involve a larger incision in the skin and local or general anesthesia.
  • Generally, the procedure is not painful and the results are as accurate as when a tissue sample is removed surgically.
  • Recovery time is brief and patients can soon resume their usual activities.

What Are The Risks Of Removing The Thyroid Gland

Behind your childs thyroid gland runs the recurrent laryngeal nerves that help to move the vocal folds and the parathyroid glands which help regulate their bodys calcium levels.

Some of the major risk factors following the removal of the thyroid gland are:

  • A hoarse/breathy voice.
  • Low calcium levels.

After surgery your child will need to take a medication to supplement the thyroid function and in some cases a medication to keep calcium levels elevated.

Other risk factors include:

  • A scar on the neck.
  • Bleeding.
  • Fluid collection under the skin.
  • The need for future procedures such as removal of the lymph nodes from the neck.
