Thyroid scanning is used to determine how active the thyroid is in manufacturing thyroid hormone. This can determine whether inflammation of the thyroid gland (thyroiditis) is present. It can also detect the presence and degree of overactivity of the gland (hyperthyroidism) or, conversely, it can determine the presence and degree of underactivity of the gland (hypothyroidism).

What Foods Are Bad for the Thyroid?
The thyroid gland is a shield-shaped gland located in your neck. It secretes the hormones T3 and T4 that control the metabolism of every cell in the body. Foods that are bad for the thyroid gland include foods from the cabbage family, soy, fried foods, wheat, foods high in caffeine, sugar, fluoride and iodine.
Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the rate of thyroid hormone production is controlled by the brain by the pituitary gland. Hypothyroidism is a very common condition and the symptoms of hypothyroidism are often subtle, but may include, constipation, memory loss, hair loss, and depression. There are a variety of causes of hypothyroidism, and treatment depends on the cause.
Thyroid Disorders Symptoms and Signs
Thyroid diseases and disorders are caused because the body either makes too much or too little thyroid hormones, which are necessary for vital functions of the body. Thyroid disease and disorder symptoms and signs depend on the type of the thyroid problem. Examples include heat or cold intolerance, sweating, weight loss or gain, palpitations, fatigue, dry skin, constipation, brittle hair, joint aches and pains, heart palpitations, edema, feeling bloated, puffiness in the face, reduced menstrual flow, changes in the frequency of bowel movements and habits, high cholesterol, hoarseness, brittle hair, difficulty swallowing, shortness of breath, a visible lump or swelling in the neck, tremors, memory problems, depression, nervousness, agitation, irritability, or poor concentration. Thyroid problems are more common in women.
There are several types of thyroid disorders including hypothyroidism, hyperthyroidism, goiters, thyroid nodules, and thyroid cancer. Symptoms vary by condition. Diagnosis is made with blood tests, scans, ultrasound, or biopsy. Treatments depend on the disorder and can include medication or surgery.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding. Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Symptoms of 12 Serious Diseases and Health Problems
Learn how to recognize early warning signs and symptoms of serious diseases and health problems, for example, chronic cough, headache, chest pain, nausea, stool color or consistency changes, heartburn, skin moles, anxiety, nightmares, suicidal thoughts, hallucinations, delusions, lightheadedness, night sweats, eye problems, confusion, depression, severe pelvic or abdominal pain, unusual vaginal discharge, and nipple changes. The symptoms and signs of serious health problems can be caused by strokes, heart attacks, cancers, reproductive problems in females (for example, cancers, fibroids, endometriosis, ovarian cysts, and sexually transmitted diseases or STDs), breast problems (for example, breast cancer and non-cancer related diseases), lung diseases (for example, chronic obstructive pulmonary disease or COPD, lung cancer, emphysema, and asthma), stomach or digestive diseases (for example, cancers, gallbladder, liver, and pancreatic diseases, ulcerative colitis, or Crohn's disease), bladder problems (for example, urinary incontinence, and kidney infections), skin cancer, muscle and joint problems, emotional problems or mental illness (for example, postpartum depression, major depression, post-traumatic stress disorder (PTSD), mania, and schizophrenia), and headache disorders (for example, migraines, or "the worst headache of your life), and eating disorders and weight problems (for example, anorexia or bulimia).
There are four major types of thyroid cancer: papillary, follicular, medullary, and anaplastic thyroid cancer. Tumors on the thyroid are referred to as thyroid nodules. Symptoms of thyroid cancer include swollen lymph nodes, pain in the throat, difficulty swallowing, hoarseness, and a lump near the Adam's apple. Treatment usually involves chemotherapy, surgery, radioactive iodine, hormone treatment or external radiation and depends upon the type of thyroid cancer, the patient's age, the tumor size, and whether the cancer has metastasized.
Hypothyroidism During Pregnancy
Hypothyroidism during pregnancy can be treated with synthetic thyroid hormones to maintain the proper thyroid hormone balance. Hypothyroidism symptoms and signs include fatigue, weight gain, lethargy, and constipation. Treatment of hypothyroidism in pregnant women is important because inadequate levels of thyroid hormones may affect the fetus and child during growth and development.
Graves' disease is an autoimmune disease that affects the thyroid. Some of the symptoms of Graves' disease include hand tremors, rapid heartbeat, trouble sleeping, enlarged thyroid, thinning of the skin or fine brittle hair. Causes of Graves' disease are thought to be multifactorial such as genes, gender, stress, and infection. Treatment for Graves' disease is generally medication.
Thyroid nodules are the most common endocrine problem in the United States. The term thyroid nodule refers to any abnormal growth that forms a lump in the thyroid gland. The vast majority of thyroid nodules are benign.
Hashimoto's thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune disorder causing inflammation of the thyroid gland. Hashimoto's thyroiditis is a type of hypothyroidism, and is the most common cause of hypothyroidism in the US. Symptoms of Hashimoto's thyroiditis may include dry skin, fatigue, weight gain, feeling cold, excessive sleepiness, dry skin, dry coarse hair, difficulty swallowing, a lump in the front of the throat, muscle cramps, mood changes, vague aches and pains, problems concentrating, leg swelling, constipation, and depression. There is no cure for Hashimoto’s thyroiditis. Diet changes, natural supplements, vitamins, or other natural products will not treat Hashimoto’s thyroiditis. Treatment for the autoimmune disorder is with thyroid hormone replacement therapy, which will be necessary for the rest of the person’s life.
The thyroid gland is a butterfly-shaped gland located in the front of the neck. The thyroid gland produces important thyroid hormones, which are produced by the pituitary gland. There are six types of thyroid problems. Home remedies, medications, surgery, lifestyle changes, and surgery.

Can Thyroid Cause Burning Mouth Syndrome?
Yes, thyroid disease may cause burning mouth syndrome. Burning mouth syndrome is a severe, painful condition characterized by burning sensations in the tongue, lips, palate (roof of the mouth), gums, inside of the cheeks, and the back of the mouth or throat. The feeling is often described as a scalding or tingling sensation.
Thyroiditis is the inflammation of the thyroid gland. The inflamed thyroid gland can release an excess of thyroid hormones into the blood stream, resulting in a temporary hyperthyroid state. Some forms of thyroiditis can be diagnosed based on tenderness and enlargement of the thyroid gland. A thyroid scan sometimes is used in making the diagnosis. Thyroiditis can also be diagnosed with a biopsy of the thyroid gland.
Hyperparathyroidism is a disorder of the parathyroid glands. There are two types of hyperparathyroidism, primary and secondary. When the parathyroid glands produce too much hormone, hyperparathyroidism is the resulting condition. Most cases of hyperparathyroidism have no evident cause. Signs and symptoms of hyperparathyroidism include fatigue, weakness, depression, loss of appetite, nausea, vomiting, constipation, or confusion. Increased calcium and phosphorous excretion may cause kidney stones. The main treatment of hyperparathyroidism is surgery (parathyroidectomy).

In hypoparathyroidism, the parathyroid gland does not produce enough parathyroid hormone. Causes of hypoparathyroidism include injury to the parathyroid glands, autoimmune disorder association, or may be present ab birth. Symptoms of hypoparathyroidism include: tingling fingers, toes, and lips, brittle nails, dry, coarse skin, dry hair; memory loss, headaches, severe muscle cramps, cataracts, malformed teeth, and convulsions. Treatment of hypoparathyroidism is to restore the calcium and phosphorus to normal levels in the body.
What Are the Warning Signs of Thyroid Cancer?
Thyroid cancer arises from the cells of the thyroid gland. The thyroid is a butterfly-shaped gland located in the front of the neck, just below Adam's apple. Warning signs of thyroid cancer include a lump in the neck, trouble swallowing, trouble breathing, voice changes, cough, weight loss, and palpitations.
What Are the Complications of Thyroid Problems?
The thyroid is a small, butterfly-shaped gland located at the anterior (front) aspect of the neck. Thyroid hormones regulate metabolism, body temperature, heartbeat and the digestive system. Hypothyroidism occurs when the thyroid gland is unable to produce sufficient levels of thyroid hormones. Hyperthyroidism occurs when the thyroid gland produces excess levels of thyroid hormones. Thyroid problems can begin at any age and women are more affected than men. The clinical presentation and complications of hypothyroidism and hyperthyroidism are different.

The thyroid gland is a small butterfly-shaped gland located in the front of the neck. Hypothyroidism is a medical condition in which the thyroid gland becomes underactive.
What Causes Hypothyroidism?
Hypothyroidism results when the thyroid gland fails to produce enough hormones. Hypothyroidism may be due to a number of factors.
What Effect Does Hypothyroidism Have on the Body?
Hypothyroidism is a condition where low levels of thyroid hormones affect various body parts. The thyroid gland is a small butterfly-shaped endocrine gland (a gland that secretes a substance called a hormone into the bloodstream). It is normally located in the front of the neck. It produces the thyroid hormones, which are released into the blood and then carried to various tissues in the body.
What Happens When You Have Hyperparathyroidism?
If you have hyperparathyroidism, it means that one or more of the parathyroid glands are overactive, resulting in the overproduction of the parathyroid hormone (PTH). Parathyroid hormones in excess can lead to an increase in the calcium levels in the blood (hypercalcemia).
