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 fat...

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.

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 student ...

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...

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 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
