Low Blood Iron Levels Might Contribute to Long COVID

Long COVID might be triggered by low iron levels in the blood from the person’s initial infection, a new study claims.

It’s remained a mystery why an estimated three out of 10 people infected with COVID go on to suffer lingering symptoms like fatigue, shortness of breath, muscle aches and “brain fog” problems with memory and concentration.

In this study, researchers tracked ...

Space Travel Takes Toll on Astronauts' Blood, Bone

When astronauts travel to space, the experience depletes their red blood cells and bone, according to a new study.

Fortunately, it appears their bodies can eventually replenish them after they've returned to Earth, thanks to fat stored in the bone marrow.

“We found that astronauts had significantly less fat in their bone marrow about a month after returning to Earth,” said seni...

Forty Percent of U.S. Girls, Young Women Are Iron Deficient

Nearly 4 out of 10 girls and young women aren't getting enough iron and they may have their periods to blame, a new U.S. study shows.

Menstrual bleeding, especially when heavy, is a major risk factor for iron deficiency and iron-deficiency anemia, the researchers explained.

There are health consequences associated with being low in iron, noted study author

  • Low-Dose Aspirin Could Raise Anemia Risks in Older Adults

    Taking daily low-dose aspirin increases the risk of anemia in the elderly, a new clinical trial suggests.

    Not only does it raise anemia risk by more than 20% in people 70 or older, it is also associated with a decline in blood iron levels, researchers report.

    “This finding about anemia and aspirin is noteworthy because, in many older people, anemia has other consequences such as f...

    Four Signs That a Young Adult Might Have Colon Cancer

    Four symptoms could provide early warning of colon cancer in younger adults.

    Being aware of these red flags could lead to earlier detection and diagnosis for those under age 50, said researchers at Washington University School of Medicine in St. Louis.

    The telltale symptoms are abdominal pain, rectal bleeding, diarrhea and iron deficiency anemia.

    The death rate from colon canc...

    Formula Feeding Raises Odds for Anemia in Very 'Preemie' Babies

    Babies born prematurely who are fed formula may need iron supplementation like their breastfed counterparts, new research suggests.

    “Just because a baby is on iron-rich formula, we should not assume all of their iron needs are being met, since iron from the formula may not have the same absorption as iron from breast milk,” said researcher Grace Power. She is a third-year medical stu...

    Repeat Blood Donation Won't Harm Your Health

    Frequent blood donors don't need to worry about iron deficiency harming their health, new research shows.

    Even though about 35% of donors can become iron deficient after repeated blood donations, researchers have found that this produces no harmful effects on either the quality of donated blood or the well-b...

    IV Anemia Meds Can Sometimes Trigger Severe Allergy

    The chances of a severe allergic reaction being triggered by intravenous (IV) iron formulations for anemia are higher with some than others, but all pose a low risk, a new study says.

    Researchers compared five IV formulations commonly used to treat iron deficiencies among older patients w...

    Astronauts at Risk of 'Space Anemia'

    Astronauts can develop a condition called space anemia because their bodies destroy more red blood cells than normal when in space, a groundbreaking study shows.

    Assessments of 14 astronauts over six months between space missions found that 54% more blood cells were destroyed while they were in space than when they were on Earth, according to findings published Jan. 14 in

  • Changing Diets Mean More Americans Are Anemic Now

    Growing numbers of Americans aren't getting enough iron in their diets most likely due to changes in farming practices and a shift away from red meat, researchers report.

    The upshot: Rates of iron-deficiency anemia are on the rise.

    "Iron deficiency remains a major public health issue even in a developed country such as the United States," Dr. Ian Griffin and Dr. Marta Rogido wr...

    Even a Little Lead in Drinking Water Can Harm People With Kidney Disease

    No amount of lead in drinking water is safe for people with kidney disease, a new study warns.

    Low levels of lead in drinking water are widespread in the United States. These findings suggest that U.S. Environmental Protection Agency (EPA) rules on allowable lead levels in drinking water pose a risk to the 30 million to 40 million Americans with kidney disease.

    "While drinking water...

    Heart Anatomy May Put Blacks at Higher Stroke Risk

    Black Americans face a heightened risk of stroke, and a new study suggests that abnormalities in the heart's upper chambers play a role.

    Experts said the findings, published Nov. 25 in the journal Neurology, point to an under-recognized factor in Black Americans' stroke risk.

    It has long been known that in the United States, Black adults are particularly hard-hit by ischemi...

    AHA News: Election Stress Didn't End on Election Day

    The good news is that after a long, heated, divisive campaign, the polls have closed, and the pre-election stress is over.

    The bad news is that now it's time for post-election stress, and the accompanying health risks are still here.

    "People often get very invested in the results of an election," said Barry Jacobs, a clinical psychologist and author in Philadelphia. "If that result ...

    Teens Can Donate Blood, But May Need Iron Supplements After

    Teens who donate blood are at significant risk for long-term iron deficiency, a new study warns.

    The concern comes as 16- to 18-year-olds have emerged as one of the fastest-growing groups of blood donors nationwide. But this study of nearly 31,000 teens who gave blood more than once between 2016 and 2018 found that roughly one in 10 were already iron-deficient when they donated for t...

    Anemia During Pregnancy Tied to Higher Odds for Autism, ADHD in Kids

    Women who suffer from anemia early in pregnancy are at risk for having a child with autism, attention-deficit/hyperactivity disorder (ADHD) and intellectual disabilities, a study by Swedish researchers suggests.

    The study couldn't prove cause and effect, but "a diagnosis of anemia earlier in pregnancy might represent a more severe and long-lasting nutrition deficiency for the fetus," ...

    Anemia Linked to Higher Odds for Dementia in Seniors

    Even mild anemia -- low levels of hemoglobin in the blood -- may raise a person's odds for Alzheimer's disease and other types of dementia, a new study finds.

    The same Dutch research also found a correlation between heightened dementia risk and high blood levels of hemoglobin.

    "With around 10% of people over age 65 having anemia in the Americas and Europe, and up to 45...

    Are You Running Short on Iron?

    Could you -- or your teenage daughter -- have an iron deficiency and not know it? If you're getting enough sleep, but still feel tired, running low on iron could be the problem.

    Iron is our most common nutrient shortfall. A serious deficiency can lead to anemia. That's when you have fewer red blood cells than normal or when those cells don't have enough hemoglobin, a protein that carr...

    Blood Donation by Teen Girls May Raise Anemia Risk

    Giving blood can be a way to help your community, but teenaged girls face special risks when donating, a new study shows.

    Specifically, they face a higher chance of developing iron deficiency and anemia, so they require additional measures to protect them, the researchers said.

    Blood donation is largely a safe procedure, but the blood loss that happens during menstruation ev...
