Standard hemoglobin screening may miss iron deficiency that could affect maternal health and newborn blood outcomes, including HDFN.

A recent mouse study suggests that low-oxygen conditions, such as being at high altitudes, could cause red blood cells to absorb excess blood glucose, potentially helping to protect against diabetes.

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue.

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid ...

Diabetes is less common among people living at high altitudes, where oxygen levels are low, than at sea level, and researchers who have discovered why that happens say the reason may lead to new ...

Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level.

SAN FRANCISCO—February 19, 2026—Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But ...

In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking ...

Red blood cells may hold the secret to fighting diabetes—by soaking up sugar when oxygen runs low. People who live high in the mountains have long been observed to develop diabetes less often than ...
