Risk Factors, Signs, and Symptoms of a Thyroid Condition By Mary Shomon | Reviewed by a board-certified physician Updated May 17, 2017 Print The thyroid, a butterfly-shaped gland located in your neck, is your master gland of metabolism. When your thyroid doesn't function it can affect every aspect of your health, especially your weight, brain chemistry (contributing or leading to depression and anxiety), energy levels, and heart health.It's estimated that as many as 59 million Americans have a thyroid problem, but the majority don't know it yet. For those of you who have been diagnosed, it sometimes seems like your thyroid symptoms—including those of an underactive thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism)—are as hard to pin down as the thyroid diagnosis itself. For those of you who are currently undiagnosed, it's important to know that untreated thyroid problems can increase your risk of obesity, heart disease, infertility, and a host of other symptoms and health problems.

But recognizing them is important, and taking action to get a proper diagnosis and thorough treatment is essential.Risk Factors for Thyroid Disease and Thyroid ConditionsSome of the key risk factors for thyroid disease include:Gender: Women face a greater risk of thyroid disease than menAge: Thyroid disease is more common as we get older, especially after 50 (but it can affect people of any age)Having a personal or family history of thyroid diseaseSurgery to remove all or part of the thyroid Radioactive iodine ablation (RAI) treatmentCurrently pregnant or in the first year after childbirthBeing a current or former smokerRecent exposure to iodine in a medical procedureTaking iodine from herbs or supplementsLiving in an area that is iodine-deficientVarious medical treatments and medicationsOverconsumption of raw foods in the goitrogen family, such as Brussels sprouts, spinach, and soyTrauma or surgery to the neckRadiation exposure, via medical treatments or nuclear accidentsIt’s important for you to know that having a personal or family history of any autoimmune disease raises your risk for thyroid disease. If you or any of your family members have an autoimmune disease, including Hashimoto's thyroiditis and Graves' disease, you should be vigilant about watching for thyroid symptoms.Some of the other well-known autoimmune conditions include rheumatoid arthritis, lupus, inflammatory bowel disease, multiple sclerosis, psoriasis, vitiligo, type 1 diabetes, Addison's disease, Cushing's syndrome, Raynaud's syndrome, Sjogren's syndrome, and alopecia.

Some of the neck-related symptoms that can point to hypothyroidism, Hashimoto’s disease, hyperthyroidism, Graves’ disease, various types of thyroiditis, and thyroid cancer include:An enlarged neckPalpable enlargement in the thyroid gland itself (goiter)A visible or palpable lump or lumps in your neckFeeling of a lump in your throat when swallowingA sore throatPain or tenderness in the neckYour neck or throat feels sensitive, and ties, scarves, or turtlenecks don’t feel comfortableEvidence of increased blood flow to the thyroid, detected by stethoscopeHypothyroidism/Hashimoto's Disease/Underactive Thyroid Signs and SymptomsClinical Signs of HypothyroidismIn addition to the neck symptoms identified above, there are some observable clinical signs of Hashimoto's disease and hypothyroidism that can be measured, detected, or identified in a clinical examination or testing with your practitioner.

Some cases of thyroiditis have no symptoms at all. There are also situations where the thyroiditis is either slowing down or speeding up the thyroid, so the symptom patterns fit into those of hypothyroidism or hyperthyroidism as described above.Some unique symptoms that are found in certain types of thyroiditis include the following:Enlargement of the thyroid (goiter)Pain, tenderness, or soreness in the neck or throat areaDifficulty swallowingFeverEnlarged lymph nodes near the thyroid.Hoarseness in your voiceA form of thyroiditis known as acute infectious thyroiditis is characterized by more significant symptoms, including:The rapid onset of neck pain and tenderness, usually only one side of the neckThe onset of pain is accompanied by fever, chills and other symptoms of infectionAn enlargement or mass in your neck area; it may be "movable" to your touch Multinodular Goiter Signs and SymptomsMultinodular goiter involves multiple nodules, as well as enlargement of the thyroid gland. Symptoms can include:a swollen, tender, tight, or full feeling in the neck or throatpain or pressure in the neckhoarseness or coughingdifficulty swallowing or breathingheart palpitationsinsomniafatigueThyroid Cancer Signs and SymptomsThyroid cancer, especially early in its development, may not cause any symptoms at all. But as a thyroid cancer grows and develops, it's more likely to cause localized symptoms in your neck and throat. Some of the symptoms that may point to thyroid cancer include the following:A lump or nodule in the neck, especially in the front of the neck in the area of the Adam's apple (Note: Sometimes the lump or nodule may grow quickly.)Enlargement of the neckEnlarged or swollen lymph nodes in the neckChanges to your voice, including hoarseness, scratchiness, and difficulty speakingDifficulty swallowing or a choking feelingDifficulty breathingPain in your neck or throat, including pain from the neck to the earsSensitivity in the neck; discomfort with neckties, turtlenecks, scarves, necklacesA persistent or chronic cough not due to allergies or illnessAsymmetry in your neck; one side may be larger than the other A Word From VerywellOne of the challenges in thyroid diagnosis is that your thyroid symptoms overlap with and are common to many other issues. This can lead to being misdiagnosed with another condition—maybe your symptoms are said to be "normal for just having had a baby,” for example—without a thorough investigation, diagnosis, and treatment of your thyroid. In some cases, without a thorough evaluation of your thyroid, you may even be diagnosed with a mental health condition like depression or panic disorder.A special situation can also be a challenge. The symptoms of Hashimoto's disease usually parallel the hypothyroidism that is a result of the disease. Occasionally, however, while the thyroid is failing, it can have periods where it sputters into life and even becomes temporarily overactive. This is known as Hashitoxicosis. Symptoms can be confusing, cycling over a period of days or weeks between hypothyroidism and hyperthyroidism symptoms.One important tip: Make sure that you bring a checklist of your risks and symptoms with you to the doctor. If you have a practitioner who—despite your potential thyroid symptoms—refuses to even do a clinical examination and blood test, or acknowledge that these symptoms may warrant further treatment, you may need to find a new doctor.Also be aware that certain health conditions may cause, be caused by, or are more common in thyroid patients. If you have any of these conditions, you should also be on the watch for potential thyroid symptoms and have your thyroid periodically evaluated. These conditions include celiac disease; fibromyalgia; chronic fatigue syndrome; Lyme disease; carpal tunnel syndrome; tarsal tunnel syndrome; tendonitis; plantar fasciitis; hypercholesterolemia (high cholesterol) especially when unresponsive to medication; infertility; recurrent miscarriage; frozen shoulder; and hemochromatosis.Sources:Bahn, R., Burch, H, Cooper, D, et al.
