**Seattle, WA -** A recent photograph of astronaut Sunita Williams, who has been stranded on the International Space Station (ISS) for over five months, has raised concerns about her health. Dr. Vinay Gupta, a pulmonologist and Seattle-based expert, notes that Williams appears “gaunt” after 152 days in space, significantly exceeding her planned eight-day mission.
Williams’s extended stay stems from a malfunction with Boeing’s Starliner spacecraft, stranding her on the ISS since June 6th. Dr. Gupta points to Williams’s “sunken cheeks” as a potential sign of weight loss, a common challenge for astronauts due to the intense calorie demands of life in space.
The lack of gravity and the need to perform even basic activities in a pressurized cabin significantly increase calorie expenditure, leading to a calorie deficit for astronauts. Additionally, NASA studies have shown that women astronauts face higher metabolic demands and blood plasma loss than their male counterparts, potentially compounding Williams’s physical strain.
Prolonged exposure to microgravity also poses a risk of muscle loss, particularly for women astronauts. Although Williams has access to high-calorie foods like cold cuts and pizza, the lack of dietary balance makes it difficult to combat muscle loss effectively. Furthermore, the lower oxygen levels on the ISS force the body to work harder, increasing metabolic strain and calorie needs.
Dr. Gupta emphasizes that even trained astronauts like Williams face health risks during prolonged space missions. “The human body can only adjust so much,” he says, urging close monitoring of Williams’s health throughout her extended stay on the ISS.
