Overview
The thyroid is a tiny, butterfly-shaped gland discovered at
the base of your neck just below Adam’s apple. It’s a bit of an intricate
network of glands called the endocrine system. The endocrine system is
accountable for coordinating many of your body’s activities. The thyroid gland creates hormones that regulate your body’s metabolism.
Various disorders can occur when your thyroid produces too
much hormone (hyperthyroidism) or not enough (hypothyroidism).
Four typical disorders of the thyroid are Hashimoto’s
thyroiditis, Graves’ disease, goiter, and thyroid nodules.
Hyperthyroidism
In hyperthyroidism, the thyroid gland is overactive. It
gives too much of its hormone. Hyperthyroidism affects approximately 1 percent
of women. It’s small common in men.
Graves’ disease is the common cause of hyperthyroidism,
affecting about 70 percent of people with an overactive thyroid. Nodules toward
the thyroid a disease called toxic nodular goiter or multinodular goiter can
further create the gland to overproduce its hormones.
Excessive thyroid hormone creation manages to symptoms such
as:
•
restlessness
•
nervousness
• racing
heart
•
irritability
• increased
sweating
• shaking
• anxiety
• trouble sleeping
• thin skin
• brittle
hair and nails
• muscle
weakness
• weight
loss
• bulging
eyes (in Graves’ disease)
Hyperthyroidism diagnosis and treatment
A blood test means levels of thyroid hormone (thyroxine, or
T4) and thyroid-stimulating hormone (TSH) in your blood. The pituitary gland
discharges TSH to excite the thyroid to produce its hormones. High thyroxine
and low TSH levels symbolize that your thyroid gland is overactive.
Your doctor might likewise give you radioactive iodine by
mouth or as an injection, and then estimate how much of it your thyroid gland
takes up. Your thyroid demands iodine to create its hormones. Bringing in a lot
of radioactive iodine is a sign that your thyroid is overactive. The low level
of radioactivity settles quickly and isn’t critical for most people.
Strategies for hyperthyroidism damage the thyroid gland or
block it from producing its hormones.
•Ant thyroid drugs such as methimazole (Tapazole) stop the thyroid from
producing its hormones.
•A healthy
dose of radioactive iodine decays the thyroid gland. You take it as a pill by
mouth. As your thyroid gland demands iodine, it additionally pulls in the
radioactive iodine, which damages the gland.
•Surgery
can be implemented to remove your thyroid gland.
If you own radioactive iodine treatment or surgery that
damages your thyroid gland, you will develop hypothyroidism and require to take
thyroid hormone daily.
Hypothyroidism
Hypothyroidism is the reverse of hyperthyroidism. The
thyroid gland is underactive, and it can’t provide enough of its hormones.
Hypothyroidism is usually created by Hashimoto’s
thyroiditis, surgery to eliminate the thyroid gland or damage from radiation
treatment. In the United States, it moves around 4.6 percent of people 12 years
old and older. Most circumstances of hypothyroidism are mild.
Too inadequate thyroid hormone production begins to symptoms
such as:
• fatigue
• dry skin
• increased
sensitivity to cold
• memory
problems
•
constipation
•
depression
• weight
gain
• weakness
• slow
heart rate
• coma
Hypothyroidism diagnosis and treatment
Your doctor will conduct blood tests to gauge your TSH and
thyroid hormone levels. A raised TSH level and low thyroxine level could
indicate that your thyroid is underactive. These levels could additionally
indicate that your pituitary gland is delivering more TSH to try to excite the
thyroid gland to make its hormone.
The principal treatment for hypothyroidism is to exercise
thyroid hormone pills. It’s essential to get the dose right because taking too
much thyroid hormone can produce symptoms of hyperthyroidism.
Hashimoto’s thyroiditis
Hashimoto’s thyroiditis is likewise known as chronic
lymphocytic thyroiditis. It’s the common cause of hypothyroidism in the United
States, moving about 14 million Americans. It can happen at any age, but it’s
several common in middle-aged women. The disease happens when the body’s immune
system mistakenly hits and slowly destroys the thyroid gland and its capacity
to produce hormones.
Some people with moderate cases of Hashimoto’s thyroiditis
may have no obvious symptoms. The disease can live stable for years, and
symptoms are often subtle. They’re additionally not specific, which means they
simulate symptoms of many other conditions. Symptoms include:
• fatigue
• depression
•
constipation
• mild
weight gain
• dry skin
• dry,
thinning hair
• pale,
puffy face
• heavy and
irregular menstruation
•
intolerance to cold
• enlarged
thyroid, or goiter
Hashimoto’s diagnosis and treatment
Examining the level of TSH is often the first step when
choosing for any type of thyroid disorder. Your doctor might require a blood
test to check for elevated levels of TSH as well as low levels of thyroid
hormone (T3 or T4) if you’re encountering some of the above symptoms.
Hashimoto’s thyroiditis is an autoimmune disease, so the blood test would
further show abnormal antibodies that strength be attacking the thyroid.
There’s no recognized cure for Hashimoto’s thyroiditis.
Hormone-replacing medication is usually used to raise thyroid hormone levels or
lower TSH levels. It can further assist relieve the symptoms of the disease.
Surgery might be needed to remove part or all of the thyroid gland in rare advanced
causes of Hashimoto’s. The disease is normally detected at an early stage and
continues stable for years because it progresses slowly.
When there’s a tremendous level of thyroid hormone in your
bloodstream, your body’s systems further up and cause symptoms that are
familiar to hyperthyroidism. These include:
• anxiety
•
irritability
• fatigue
• hand
tremors
• increased
or irregular heartbeat
• excessive
sweating
•
difficulty sleeping
• diarrhea
or frequent bowel movements
• altered
menstrual cycle
• goiter
• bulging
eyes and vision problems
Goiter
Goiter is a noncancerous increase of the thyroid gland. The
various common problem of goiter worldwide is an iodine deficiency in the diet.
Researchers speculate that goiter afflicts 200 million of the 800 million
people who are iodine-deficient worldwide.
Goiter can strike anyone at any age, particularly in areas
of the world where foods rich in iodine are in low supply. However, goiters are
also common after the age of 40 and in women, who are also prone to have
thyroid disorders. Other risk agents include family medical history, certain
medication practices, pregnancy, and radiation exposure.
Their strength was not any symptoms if the goiter isn’t
severe. The goiter may make one or more of the following symptoms if it becomes
large enough, depending on the size:
• swelling
or tightness in your neck
• problems
breathing or swallowing
• coughing
or wheezing
•
hoarseness of voice
Goiter diagnosis and treatment
Your doctor will know your neck area and have you swallow
through a routine physical exam. Blood tests will expose the levels of thyroid
hormone, TSH, and antibodies in your bloodstream. This command diagnoses
thyroid diseases that are normally a matter of goiter. An ultrasound of the
thyroid can check for increasing or nodules.
Goiter is normally treated simply when it becomes severe
enough to cause symptoms. You can practice small doses of iodine if the goiter
is the result of iodine deficiency. Radioactive iodine can withdraw the thyroid
gland. Surgery will transfer all or part of the gland. The treatments normally
overlap because goiter is often a symptom of hyperthyroidism.
Goiters are usually associated with extremely treatable
thyroid disorders, such as Graves’ disease. Although goiters aren’t normally a
cause for concern, they can create serious complications if they’re left
untreated. These difficulties can involve difficulty breathing and swallowing.
Thyroid nodules
Thyroid nodules hold bumps that develop on or in the thyroid
gland. About 1 percent of men and 5 percent of women being in iodine-sufficient
countries have thyroid nodules that are kind enough to feel. About 50 percent
of people will have bulges that are too tiny to feel.
The problems aren’t always known but can incorporate iodine
deficiency and Hashimoto’s thyroiditis. The nodules can be solid or
fluid-filled.
Most are benign, but they can additionally be cancerous in a
small percentage of cases. As among other thyroid-related problems, nodules are
more prevalent in women than men, and the risk in both sexes increases with
age.
Most thyroid buds don’t cause any symptoms. However, if they
become large enough, they can create swelling in your neck and lead to
breathing and swallowing difficulties, pain, and goiter.
Some nodules create thyroid hormones, causing abnormally
high levels in the bloodstream. When this occurs, symptoms are similar to those
of hyperthyroidism and can include:
• high
pulse rate
•
nervousness
• increased
appetite
• tremors
• weight
loss
• clammy
skin
On the other hand, symptoms will be related to
hypothyroidism if the nodules are connected with Hashimoto’s disease. This
includes:
• fatigue
• weight
gain
• hair loss
• dry skin
• cold
intolerance
Thyroid nodules diagnosis and treatment
Most nodules are discovered during a normal physical exam.
They can also be detected during an ultrasound, CT scan, or MRI. Once a nodule
is detected, other methods of a TSH test including a thyroid scan can check for
hyperthyroidism or hypothyroidism. A fine-needle aspiration biopsy is used to
take an example of cells from the nodule and determine whether the nodule is
cancerous.

Gracious thyroid nodules aren’t life-threatening and
normally don’t need treatment. Typically, nothing is done to eliminate the
nodule if it doesn’t change over time. Your doctor may do different biopsies
and recommend radioactive iodine to shrink the buds if it grows.
Thyroid cancer changes less than 4 percent of the
population. The treatment your doctor prescribes will vary depending on the
type of tumor. Raising the thyroid through surgery is usually the treatment of
choice. Radiation therapy is seldom used with or without surgery. Chemotherapy
is usually needed if cancer spreads to other parts of the body.
