What is hypothyroidism?

Hypothyroidism, besides called underactive thyroid, is when the thyroid gland doesn't brand enough thyroid hormones to meet your torso'due south needs. The thyroid is a modest, butterfly-shaped gland in the front of your neck. Thyroid hormones control the way your torso uses energy, so they affect virtually every organ in your body, even the way your eye beats. Without enough thyroid hormones, many of your trunk's functions slow down.

The thyroid is a small gland in your cervix that makes thyroid hormones.

How common is hypothyroidism?

Nearly 5 out of 100 Americans ages 12 years and older have hypothyroidism, although virtually cases are balmy or have few obvious symptoms.¹

Who is more than likely to develop hypothyroidism?

Women are much more than likely than men to develop hypothyroidism. The disease is as well more common among people older than age 60.¹

You are more likely to have hypothyroidism if you

• had a thyroid problem before, such as a goiter
• had surgery or radioactive iodine to correct a thyroid problem
• received radiations treatment to the thyroid, neck, or chest
• have a family unit history of thyroid disease
• were pregnant in the past vi months
• accept Turner syndrome, a genetic disorder that affects women

Your thyroid is too more than likely to be underactive if you take other health bug, including

• Celiac disease
• Sjögren'due south syndrome, a illness that causes dry eyes and mouth
• pernicious anemia, a condition caused past a vitamin B12 deficiency
• type 1 or type two diabetes
• rheumatoid arthritis, an autoimmune disease that affects the joints
• lupus, a chronic autoimmune inflammatory condition

Is hypothyroidism during pregnancy a trouble?

Left untreated, hypothyroidism during pregnancy tin bear on both mother and infant. Even so, thyroid medicines can help prevent issues and are safe to accept during pregnancy. Many women taking thyroid hormone medicine need a higher dose during pregnancy, so contact your doc right abroad if you lot find out you're pregnant.

What are the complications of hypothyroidism?

Hypothyroidism tin contribute to high cholesterol. If y'all have loftier cholesterol, yous should go tested for hypothyroidism. Rarely, severe untreated hypothyroidism may pb to myxedema coma, an farthermost form of hypothyroidism in which the body'due south functions tiresome to a life-threatening point. Myxedema coma requires immediate medical treatment.

What are the symptoms of hypothyroidism?

Hypothyroidism has many symptoms that tin can vary from person to person. Some mutual symptoms of hypothyroidism include

• fatigue
• weight gain
• problem tolerating common cold
• joint and muscle hurting
• dry out pare or dry, thinning pilus
• heavy or irregular menstrual periods or fertility problems
• slowed heart rate
• depression

Dry, thinning hair is 1 of many symptoms that might betoken hypothyroidism.

Because hypothyroidism develops slowly, yous may non notice symptoms of the disease for months or fifty-fifty years.

Many of these symptoms, especially fatigue and weight gain, are mutual and do not necessarily mean yous have a thyroid problem.

What causes hypothyroidism?

Hypothyroidism has several causes, including

• Hashimoto'due south affliction
• thyroiditis, or inflammation of the thyroid
• congenital hypothyroidism, or hypothyroidism that is present at birth
• surgical removal of part or all of the thyroid
• radiation handling of the thyroid
• some medicines

Less ofttimes, hypothyroidism is caused by besides much or likewise little iodine in the diet or by disorders of the pituitary gland or hypothalamus.¹ Iodine deficiency, however, is extremely rare in the United States.

Hashimoto's disease

Hashimoto'southward disease, an autoimmune disorder, is the most mutual cause of hypothyroidism. With this disease, your immune arrangement attacks the thyroid. The thyroid becomes inflamed and can't brand enough thyroid hormones.

Thyroiditis

Thyroiditis, an inflammation of your thyroid, causes stored thyroid hormone to leak out of your thyroid gland. At first, the leakage increases your blood'southward hormone levels, leading to thyrotoxicosis, a condition in which thyroid hormone levels are likewise loftier. The thyrotoxicosis may terminal for many months. After that, your thyroid may become underactive and, over time, the condition may become permanent, requiring thyroid hormone replacement.

Three types of thyroiditis can cause thyrotoxicosis followed by hypothyroidism.^two

• Subacute thyroiditis involves a painfully inflamed and enlarged thyroid.
• Postpartum thyroiditis develops after a woman gives nativity.
• Silent thyroiditis is painless, even though your thyroid may be enlarged. Experts think it is probably an autoimmune condition.

Built hypothyroidism

Some babies are born with a thyroid that is not fully developed or does not work properly. If untreated, congenital hypothyroidism tin lead to intellectual disability and growth failure—when a babe doesn't grow as expected. Early treatment can prevent these problems. That's why nigh newborns in the Usa are tested for hypothyroidism.

Surgical removal of part or all of the thyroid

When surgeons remove part of the thyroid, the remaining part may produce normal amounts of thyroid hormone. But some people who have this surgery may develop hypothyroidism. Removing the entire thyroid always results in hypothyroidism.

Surgeons may remove part or all of the thyroid as a handling for

• hyperthyroidism
• a big goiter
• thyroid nodules, which are noncancerous tumors or lumps in the thyroid that tin produce likewise much thyroid hormone
• pocket-size thyroid cancers

Radiation treatment of the thyroid

Radioactive iodine, a common treatment for hyperthyroidism, gradually destroys thyroid cells. If y'all receive radioactive iodine treatment, yous probably will eventually develop hypothyroidism. Doctors also treat people who have head or neck cancers with external radiation therapy, which tin also impairment the thyroid if information technology is included in the treatment.

Medicines

Some medicines can interfere with thyroid hormone production and pb to hypothyroidism, including sure

• heart medicines
• bipolar disorder medicines
• cancer medicines

Several recently developed cancer medicines, in particular, can either bear upon the thyroid directly or affect information technology indirectly by damaging the pituitary gland.

How practice doctors diagnose hypothyroidism?

Your dr. will take your medical history and perform a physical exam. A hypothyroidism diagnosis can't be based on symptoms alone because many of its symptoms are the aforementioned every bit those of other diseases.¹ That'south why your doctor may utilize several thyroid blood tests and imaging tests to ostend the diagnosis and find its cause.

Because hypothyroidism can cause fertility problems, women who have trouble getting pregnant often get tested for thyroid problems.

A claret test might ostend a diagnosis of hypothyroidism.

How do doctors treat hypothyroidism?

Hypothyroidism is treated by replacing the hormones that your ain thyroid can no longer make. You volition take levothyroxine, a thyroid hormone medicine identical to a hormone a salubrious thyroid makes.³ Normally prescribed in pill class, this medicine is also available equally a liquid and every bit a soft gel capsule. These newer formulas may help people with digestive problems to absorb the thyroid hormone. Your dr. may recommend taking the medicine in the morning before eating.

Your dr. volition give you lot a blood exam well-nigh six to 8 weeks after yous brainstorm taking the medicine, adjusting your dose if needed. Each time your dose is adjusted, you lot'll have another claret test. Once you've reached a dose that's working for you, your doctor will probably echo the claret examination in half dozen months and and so once a year.

Your hypothyroidism most probable can be completely controlled with thyroid hormone medicine, as long as yous have the recommended dose as instructed. Never terminate taking your medicine without talking with your doctor starting time. Taking too much thyroid hormone medicine can cause serious problems, such as atrial fibrillation or osteoporosis.ⁱ

How does eating, diet, and diet affect hypothyroidism?

What are clinical trials for hypothyroidism?

Clinical trials—and other types of clinical studies—are part of medical research and involve people like y'all. When y'all volunteer to accept part in a clinical report, you help doctors and researchers learn more most disease and improve wellness intendance for people in the future.

Researchers are studying many aspects of hypothyroidism, such as

• understanding how the disease progresses, its clinical presentation, and genetics
• investigating how effective and condom levothyroxine is for people with chronic kidney disease

Detect out if clinical studies are correct for you.

Scout a video of NIDDK Director Dr. Griffin P. Rodgers explaining the importance of participating in clinical trials.

What clinical studies for hypothyroidism are looking for participants?

Yous can view a filtered listing of clinical studies on hypothyroidism that are open up and recruiting at www.ClinicalTrials.gov. You tin can expand or narrow the list to include clinical studies from industry, universities, and individuals; however, the National Institutes of Wellness does not review these studies and cannot ensure they are rubber.
