Prevalence Of Hypothyroidism In Adults: An Epidemiological Study In Eight Cities Of India PMC

hypothyroid statistics

Estrogen, considered the primary female hormone, is thought to play a role. Presence and type of HT were defined by elevated TSH and subnormal/low FT4 levels identified using the NHANES variables LBDTSH1S and LBXT4F, respectively. Covariables, such as patient demographic characteristics, insurance status, and self-reported comorbidities, were indexed using the NHANES variable codes listed in Table 1.

While associations can be observed regarding comorbidities with treated or untreated HT, temporality cannot be determined as related to development of HT. Likewise, using cross-sectional data does not allow for retesting for overt HT or subclinical HT, which is important for confirming a diagnosis of HT. NHANES data that contain the thyroid panel, while ideal in estimating US prevalence of treated and untreated HT, are somewhat dated. Current cycles of NHANES do not collect thyroid panels, and it is unknown this page if these panels will be collected in subsequent cycles. Likewise, data obtained from patient surveys rely on patient perspectives and memory and are, as a result, subject to recall bias, which could affect survey outcomes [31]. Moreover, data regarding thyroid function tests prior to the start of replacement therapy was not available, thus it is possible that patients with normal TSH/FT4 levels but prescribed therapy are included in and may inflate the estimation of the prevalence of overt HT.

A hypothyroidism diagnosis can’t be based on symptoms alone because many of its symptoms are the same as those of other diseases.1 That’s why your doctor may use several thyroid blood tests and imaging tests to confirm the diagnosis and find its cause. Radioactive iodine, a common treatment for hyperthyroidism, gradually destroys thyroid cells. If you receive radioactive iodine treatment, you probably will eventually develop hypothyroidism. Doctors also treat people who have head or neck cancers with external radiation therapy, which can also damage the thyroid if it is included in the treatment. Rarely, severe untreated hypothyroidism may lead to myxedema coma, an extreme form of hypothyroidism in which the body’s functions slow to a life-threatening point. Hypothyroidism, also called underactive thyroid, is when the thyroid gland doesn’t make enough thyroid hormones to meet your body’s needs.

These values are marked declines from those first reported in 2000 (18.3% and 22.2%, respectively), most likely due to advancements in therapies (ie, statins) [22, 23]. It is important to note that over half of patients diagnosed with hyperlipidemia are receiving treatment [23, 24]. In any person, a healthcare this page provider will take a medical history and conduct a physical exam if hypothyroidism is suspected. Because the symptoms of hypothyroidism are often vague and overlap with other diseases, diagnosis requires blood tests to measure thyroid stimulating hormone (TSH) and other thyroid hormones such as T3 and T4.

Endocrine Society is a global community of physicians and scientists dedicated to accelerating scientific breakthroughs and improving patient health and well being. Hashimoto’s disease appears to be more common in White Americans and less common in Black Americans, Asian Americans, and Pacific Islanders. We would like to thank Andrea Bothwell and Marion Barnett who drafted an outline and early version of this manuscript on behalf of Springer Healthcare. Hypothyroidism also appears to be more prevalent in white people than in black or Hispanic people [29 32]. Hypothyroidism is more prevalent in women with small stature at birth and low body mass index in childhood. If you are pregnant, you need more iodine because the baby gets iodine from your diet.

Commonly used medications such as proton pump inhibitors also have a negative impact on levothyroxine absorption. Maintaining a consistent formulation or brand of levothyroxine is essential.[11] There can be slight variations in the dose of the generic formulations, which can have a clinical impact in a small sub-set of very sensitive hypothyroid patients. Clinical trials and other types of clinical studies are part of medical more hints research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future. When surgeons remove part of the thyroid, the remaining part may produce normal amounts of thyroid hormone. People with long-term untreated and severe hypothyroidism may experience a rare condition known as myxedema coma.
