If a heart attack survivor also has an underactive thyroid, treating them with supplemental thyroid hormone probably won't help, new research shows.
The study found that use of the hormonal drug, called levothyroxine, didn't improve heart muscle function in heart attack patients diagnosed with "subclinical hypothyroidism" -- an underactive thyroid.
When something as routine as grocery shopping might lead to a deadly COVID-19 infection, stress is inevitable -- and that extra tension can make it harder for people with diabetes to manage their disease.
The reason? The stress hormone cortisol is linked to higher blood sugar levels, according to a new study.
Under stress, the body releases cortisol, which leads to an inc...
Doctors at one Ohio hospital system have discovered yet another possible consequence of the COVID-19 pandemic: More cases of "broken heart syndrome."
The condition -- which doctors call stress cardiomyopathy -- appears similar to a heart attack, with symptoms such as chest pain and breathlessness. But its cause is different: Experts believe it reflects a temporary weakness in the hear...
Women have more Alzheimer's disease-related changes in the brain than men, and this may be linked to hormonal disruptions at menopause, researchers say.
"About two-thirds of people living with Alzheimer's are women, and the general thinking has been it's because women tend to live longer," said study author Lisa Mosconi of Weill Cornell Medicine in New York City.
Genetics may explain why some women gain weight when using a popular method of birth control, researchers say.
"For years, women have said that birth control causes them to gain weight but many doctors failed to take them seriously," said lead study author Dr. Aaron Lazorwitz. He's assistant professor of obstetrics/gynecology and family planning at the University of Colorado School of...
Many people with high blood pressure may have an unrecognized hormonal condition driving their numbers up, a new study suggests.
The condition, called primary aldosteronism, arises when the adrenal glands overproduce the hormone aldosterone. That causes the body to retain sodium and lose potassium, spurring a spike in blood pressure.
A testosterone-lowering drug can reduce male pedophiles' risk of sexually abusing children, according to a new Swedish study.
The drug, called degarelix, is used to treat prostate cancer and turns off production of testosterone. It's given by injection every three months and can lower testosterone levels within hours, according to researchers.
MONDAY, May 4, 2020 (HealthDay News) -- The medication Synthroid (levothyroxine) is often used to treat a condition called subclinical hypothyroidism, but a new study suggests the treatment might be a waste of time.
For the study, researchers followed 638 people aged 65 and older with subclinical hypothyroidism, also known as mild thyroid failure. About half of the patients were give...
People sometimes refer to menopause as "the change of life," but many women are surprised that one of the things that changes is their skin, an expert says.
"Although fluctuating hormones during menopause can result in a number of skin changes, these don't need to be disruptive to daily life," said New York City dermatologist Dr. Diane Berson. "With the right care, women can continue ...
When pregnant women use cosmetics containing parabens, their children may have a greater likelihood of becoming overweight, a new study suggests.
Parabens are chemicals that have long been used as a preservative in cosmetics and body care products. A number of studies have suggested that parabens mimic estrogens in the body and may disrupt the normal function of hormones.
High levels of the sex hormone testosterone may trigger different health problems in men and women, a new study reveals.
In women, testosterone may increase the risk for type 2 diabetes, while in men it lowers that risk. But high levels of testosterone increase the risk for breast and endometrial cancer in women and prostate cancer in men, the researchers reported.
Many women use birth control pills or other hormone-based contraceptives to enjoy sex without fear of an unplanned pregnancy. But could they kill your mojo?
There has been some concern that a woman's sex drive can drop after starting a new form of hormone-based birth control. Sex drive studies involving the pill, the patch and hormone-releasing intrauterine devices (IUDs) have been m...
If you're a young adult, start thinking about your bone health, an expert advises.
Most people reach peak bone mass -- the strongest bones they'll ever have -- between 25 and 30 years of age, according to Dr. Philip Bosha, a physician with Penn State Sports Medicine in State College, Pa.
"To some extent, genetics determines the peak, but lifestyle influences, such as diet an...
Researchers are exploring fertility preservation in transgender women. And while they say there are no guarantees, they report it's possible to start producing sperm after stopping drugs that suppress maleness.
In a new case report, researchers found one of two patients produced sperm after discontinuing her puberty-halting medication. However, the other patient wasn't able to produc...
New British research is bolstering the theory that elevated levels of sex hormones in the uterus could play a role in autism risk.
Prior studies had already implicated higher uterine concentrations of male sex hormones -- androgens -- in increasing the odds for an autism spectrum disorder, noted a team led by Simon Baron-Cohen. He directs the Autism Research Center at the University o...
SATURDAY, May 4, 2019 (HealthDay News) -- Buyer beware: When it comes to testosterone supplements, men should know a new study finds there is precious little evidence to support claims they will boost testosterone levels, sex drive, strength and overall energy.
To come to this conclusion, the researchers first broke down 50 testosterone supplements into th...
Polycystic ovary syndrome is a common cause of infertility and type 2 diabetes, but little is known about its origins. Now, new research suggests a gene involved in male hormone production plays a big role in the disorder's development.
"We're starting to make headway on what causes PCOS [polycystic ovary syndrome]. It's very frustrating for patients because it's poorly understood," ...
For women with hormone-driven breast cancer, adding radiation to hormone therapy might keep their cancer from coming back for up to a decade, a new study finds.
Breast cancer didn't come back in the same breast for 97.5% of women who had radiation therapy plus hormone therapy compared to just over 92% of women who had hormone therapy alone, the researchers said.
A new study suggests that the fewer menstrual periods a woman has in her lifetime, the higher her risk of dementia -- though the reasons, for now, are unclear.
The study was based on close to 16,000 women. It found that those who started having periods at age 16 or later were more likely to develop dementia than women who started menstruating at a more typical age.
When couples experience recurrent pregnancy loss, it's natural for them to want to know why. Now, a new study suggests that sperm DNA damage could be a factor.
Recurrent pregnancy loss is defined as the consecutive loss of three or more pregnancies before 20 weeks' gestation. It affects up to 2 percent of couples and, in many cases, it is difficult to ident...
Hormonal treatment can help control prostate cancer but may increase a man's risk of depression, a new study by Danish researchers suggests.
Male hormones, such as testosterone, are known to fuel the growth of prostate tumors. So doctors use drugs to reduce hormone production. But that can bring on tough side effects, such as incontinence or impotence.
Having a twin brother could put a woman at a lasting disadvantage, and exposure to his testosterone before birth may play a role, a new study suggests.
Researchers analyzed data on 13,800 twin births in Norway between 1967 and 1978. Compared to women with a twin sister, those with a twin brother were 15 percent less likely to finish high school and nearly 4 percent less likely to com...
High testosterone levels can drastically increase a man's risk of heart failure and stroke-causing blood clots, a new study reports.
Men with a genetic predisposition to high testosterone levels have a nearly eightfold increased risk of heart failure and twice the risk of thromboembolism (blood clots that can block veins or arteries leading to the brain or lungs), researchers found.
Young children with autism are more than twice as likely to have sleep problems than typical kids or those with other developmental delays, a new study reports.
Several factors profoundly affect the sleep of 2- to 5-year-olds with autism spectrum disorder (ASD), said lead researcher Dr. Ann Reynolds. They are more likely to resist their bedtime, have trouble getting to sleep, suffer f...
The hormone prolactin -- most commonly associated with breastfeeding -- may play a role in reducing the risk of type 2 diabetes, a new study suggests.
Researchers found that women with the highest levels of the hormone, though still in the normal range, had a 27 percent reduced risk of developing type 2 diabetes compared to those with the lowest levels in the normal range.
