Underactive Thyroid Not Linked to Memory Problems

Posted 30 Dec 2013 by Drugs.com

MONDAY, Dec. 30, 2013 – Hypothyroidism, a condition that causes low or no thyroid hormone production, is not linked to mild dementia or impaired brain function, a new study suggests. Although more research is needed, the scientists said their findings add to mounting evidence that the thyroid gland disorder is not tied to the memory and thinking problems known as "mild cognitive impairment." Some prior evidence has suggested that changes in the body's endocrine system, including thyroid function, might be linked to Alzheimer's disease and other forms of dementia, said researchers led by Dr. Ajay Parsaik, of the University of Texas Medical School in Houston. Mild cognitive impairment, in particular, is thought to be an early warning sign of the memory-robbing disorder Alzheimer's disease, the study authors said in a university news release. In conducting the study, Parsaik's team ... Read more

Thyroid Levels of Older Hospital Patients May Be Linked to Survival

Posted 30 Oct 2013 by Drugs.com

WEDNESDAY, Oct. 30 – Older hospital patients who have low thyroid hormone levels may face higher odds of dying, according to a new study. The thyroid, a gland in the neck, produces hormones that regulate the body's temperature, oxygen consumption and metabolism. The gland produces two hormones – triiodothyronine (T3) and thyroxine (T4) – that travel through the blood to spur activity in various tissues. The findings were to be published in the December issue of the Journal of Clinical Endocrinology & Metabolism. "When older individuals have low levels of thyroid hormones, particularly T3, it reflects that the body is weak and more susceptible to the harmful effects of disease," study author Dr. Pedro Iglesias, of Hospital Ramon y Cajal in Madrid, said in a journal news release. "As a result, older individuals who have a reduced ability to synthesize T3 hormones have a higher rate of ... Read more

Underactive Thyroid and Heart Failure a Bad Combination: Study

Posted 22 May 2013 by Drugs.com

WEDNESDAY, May 22 – People with heart failure are more likely to experience poorer health from having a thyroid gland that is even mildly underactive, according to a new study. And among black patients, the researchers found an increased risk of death linked to the condition, which is known as hypothyroidism. "This study is the first to show that African-Americans who have hypothyroidism face a greater risk of death than patients of other racial and ethnic groups," Dr. Connie Rhee, of Brigham and Women's Hospital in Boston, said in a news release from the Endocrine Society. "This elevated risk exists despite the fact that hypothyroidism is less common in the African-American population compared to other groups." "More research is needed to confirm these findings and to determine the underlying reasons why hypothyroidism has a differential impact on people of different races and ... Read more

People With Type 1 Diabetes at Risk of Thyroid Disease

Posted 15 Mar 2013 by Drugs.com

FRIDAY, March 15 – People who have type 1 diabetes are more likely than others to develop an autoimmune thyroid condition. Though estimates vary, the rate of thyroid disease – either under- or overactive thyroid – may be as high as 30 percent in people with type 1 diabetes, according to Dr. Betul Hatipoglu, an endocrinologist with the Cleveland Clinic in Ohio. And the odds are especially high for women, whether they have diabetes or not, she said, noting that women are eight times more likely than men to develop thyroid disease. "I tell my patients thyroid disease and type 1 diabetes are sister diseases, like branches of a tree," she said. "Each is different, but the root is the same. And, that root is autoimmunity, where the immune system is attacking your own healthy endocrine parts." Hatipoglu also noted that autoimmune diseases often run in families. A grandparent may have had ... Read more

N.Y. Woman Balances Thyroid Disease and Diabetes

Posted 15 Mar 2013 by Drugs.com

FRIDAY, March 15 – Jet Landis was only 4 years old when she was diagnosed with type 1 diabetes in 1992. Even though she was so young, she can still recall the extreme thirst she felt because of diabetes. Landis was lucky, though, because her mother was a nurse and recognized the signs of type 1 diabetes before her condition became life-threatening. Still, the diagnosis was a difficult one because it meant that, while still a preschooler, Landis had to begin taking daily insulin injections to replace the insulin her body was no longer making. Multiple daily injections of insulin remain part of Landis's routine. Now in her early 20s, she manages her diabetes with the help of a continuous glucose monitor to measure blood glucose levels. The device, which is inserted under her skin, has to be changed about once a week. She also has to poke her fingers to do a standard blood sugar test to ... Read more

BPA Exposure Impacts Pregnant Women's Thyroids, Study Suggests

Posted 4 Oct 2012 by Drugs.com

THURSDAY, Oct. 4 – New research finds that BPA – a chemical widely used in the manufacture of hard plastics, cans and even store receipts – is associated with lower levels of thyroid hormone in both pregnant women and their newborn boys. At this point, the implications of the findings to human health are unclear, although abnormal thyroid hormone levels have been associated with changes in thinking skills, behavior and growth, according to the research, which was published online Oct. 4 in Environmental Health Perspectives. This is the first study to show an association between BPA (or bisphenol A) and thyroid hormone in pregnant women, according to the study's lead author, Kim Harley, an adjunct associate professor of public health at the University of California, Berkeley. Almost all – 95 percent – of women of reproductive age have enough BPA in their urine to be detectable. BPA ... Read more

Soy Formula May Harm Babies With Underactive Thyroid: Report

Posted 21 Aug 2012 by Drugs.com

TUESDAY, Aug. 21 – Babies born with congenital hypothyroidism – a condition that causes low or no thyroid hormone production – shouldn't be given soy formula, new research indicates. Soy can interfere with the absorption of levothyroxine, the medication that replaces the missing thyroid hormone. If babies and toddlers don't get enough replacement thyroid medication, their brains can't develop properly, experts note. Two case studies that highlight the importance of this issue are detailed by doctors from the University of California, San Diego, in the September issue of the journal Pediatrics. "Soy products interfere with levothyroxine absorption and endanger infants and young children with congenital hypothyroidism who are at risk for developmental and growth delay," wrote the authors of the case studies. "When a child is hypothyroid at birth, it's really a medical emergency," said ... Read more

Thyroid Treatment Guidelines for Pregnant Women Revised

Posted 14 Aug 2012 by Drugs.com

TUESDAY, Aug. 14 – Thyroid hormone is critical for normal fetal brain development, and hormonal problems among pregnant women must be properly managed, according to the Endocrine Society, which just revised its guidelines on treating thyroid-related medical issues before, during and after pregnancy. Too much or not enough thyroid hormone can harm both women and their unborn babies, the experts said. The treatment guidelines update the 2007 version. "Pregnancy may affect the course of thyroid diseases and, conversely, thyroid diseases may affect the course of pregnancy," said lead study author Dr. Leslie de Groot, a research professor at the University of Rhode Island, in a society news release. "Pregnant women may be under the care of multiple health care professionals, including obstetricians, nurse midwives, family practitioners and endocrinologists, making the development of ...

Screening Moms-to-Be for Thyroid Trouble May Not Help Offspring

Posted 8 Feb 2012 by Drugs.com

WEDNESDAY, Feb. 8 – Screening and treating expectant moms for thyroid problems at the end of the first trimester doesn't improve children's IQs at age 3, a new study finds. Thyroid hormones are crucial for the development of a baby's brain and nervous system, and until the middle of the second trimester, those hormones come from the mother. Since a malfunctioning thyroid in the mother has been associated with mental impairments in her child, researchers reasoned that if they screened for maternal thyroid disease in pregnancy and treated any problems found, they might be able to improve function in the offspring. Treatment includes supplementary thyroid hormone medications such as levothyroxine. However, this large study found that the intervention did not seem to help. "This trial failed to show any beneficial effect on cognitive [mental] function in 3-year-old children whose mothers ... Read more

Buyer, Beware of Over-the-Counter Thyroid Supplements: Study

Posted 4 Nov 2011 by Drugs.com

FRIDAY, Nov. 4 – Over-the-counter "thyroid support" supplements commonly used for weight loss and to fight fatigue are mostly ineffective and may pose a health threat, a new study warns. The supplements contain widely varying amounts of two kinds of thyroid hormones – triiodothyronine (T3) and thyroxine (T4) – apparently derived largely from chopped up animal thyroid glands, according to senior investigator Dr. Victor Bernet, an endocrinologist at the Mayo Clinic in Florida. These two hormones are regulated by the U.S. Food and Drug Administration and intended for use only in prescription drugs because they can cause serious health problems, including increased heart rate, heart irregularities and palpitations, nervousness and diarrhea, he explained. The researchers analyzed 10 commercially available OTC thyroid supplements and found that nine contained T3 and five of them would ... Read more

Mainstay Meds Often Cut Off Accidentally After Hospital Stay

Posted 23 Aug 2011 by Drugs.com

TUESDAY, Aug. 23 – Many patients who are hospitalized fail to receive their regular medications for chronic conditions during their stay and often fail to restart them when they're discharged, researchers say. Patients treated in the intensive care unit (ICU) are even less likely to resume their regular medication schedule after discharge, probably because there are so many "transitions of care" to different units within the hospital and so many different care teams involved, the study found. "Sometimes we do a pretty good job of taking care of people in the hospital, but we don't do a great job of making the transition back to the community," said Dr. Chaim Bell, lead author of a study published in the Aug. 24/31 issue of the Journal of the American Medical Association. "That can lead to whole host of problems." Unintended discontinuation of vital medications can lead to another ... Read more

Exposure to Common Chemicals May Affect Thyroid Function

Posted 14 Jul 2011 by Drugs.com

THURSDAY, July 14 – Chemicals called phthalates and bisphenol-A (BPA) that are found in solvents, plastics and numerous household products may alter levels of thyroid hormones in the body, according to a new study. Thyroid hormones play a role in many critical bodily functions, including reproduction and metabolism. Researchers from the University of Michigan School of Public Health used data from the U.S. National Health and Nutrition Examination Survey to compare thyroid levels and traces of phthalates and BPA in urine samples of 1,346 adults and 329 teenagers. Their findings confirmed previous research linking BPA – used in certain plastic water bottles and the linings of canned foods – with disruptions in thyroid hormone levels, they said. Overall, higher concentrations of the chemicals had an inverse impact on thyroid levels, said study lead author John Meeker, an assistant ... Read more

With the Thyroid, Too Much or Too Little Spark Trouble

Posted 11 Apr 2011 by Drugs.com

FRIDAY, April 8 – The human body's intricate framework of interconnected systems, which work together to maintain health and life, depend on one small, butterfly-shaped gland that weighs less than half an ounce. The thyroid gland, located in the front of the neck, releases hormones that regulate metabolism, directing the body to break down food into energy and then either use it immediately or store it for later use. "The thyroid gland is essential to life," said Dr. Peter A. Singer, a professor of endocrinology at the University of Southern California, a past president of the American Thyroid Association and a board member of the American Association of Clinical Endocrinologists. "If you didn't have a thyroid gland, you could not survive." When disease strikes the thyroid, this directly affects the body's metabolism by altering the amount of hormone produced by the gland. Too little ... Read more

Studies Evaluate Thyroid Treatment During Pregnancy

Posted 16 Jul 2010 by Drugs.com

FRIDAY, Sept. 25 – Thyroid problems in pregnant women can cause serious consequences in both mothers and children, says an expert familiar with ongoing research into treatments. An update on clinical trials was to be presented Friday at the annual meeting of the American Thyroid Association, in Palm Beach, Fla. "Detection and management of thyroid dysfunction during pregnancy is important for many reasons," Dr. Alex Stagnaro-Green, senior associate dean at the Touro University College of Medicine in New Jersey, said in a news release from the association. "For pregnant women with hypothyroidism, there is an increased risk for miscarriage, an increased preterm delivery, an increased risk for decreased IQ and visual motor defects for their offspring." Stagnaro-Green said that researchers at the U.S. National Institute of Child Health and Human Development are conducting a randomized ... Read more

Slightly Underactive Thyroid May Be a Plus

Posted 12 Jun 2009 by Drugs.com

FRIDAY, June 12 – Instead of being a medical problem in need of treatment, an underactive thyroid in old age might actually help you live longer, a new study says. Researchers tested the levels of thyroid stimulating hormone (TSH) in 236 Ashkenazi Jews, who were about 100 years old, and their children, most of whom were in their 70s. For comparison with people not related by blood, they tested the TSH levels of the children's spouses. The study found that the Ashkenazi centenarians had slightly elevated levels of TSH, which is a sign of mild hypothyroidism, or an underactive thyroid. The centenarian's children also had slightly elevated levels of TSH, compared with that of their spouses. The thyroid, a butterfly-shaped gland in the front of the neck, helps regulate metabolism. Though researchers aren't sure why, a slightly slower metabolism might promote longevity. "This is sort of a ... Read more
