Astronaut Sunita Williams’ significant weight loss after 155 days in space has raised health concerns. NASA officials are closely monitoring her condition as she struggles to maintain her weight in a challenging microgravity environment.

Sunita Williams's extended stay on the International Space Station has led to alarming weight loss, prompting NASA to prioritise her health.

Williams, who has been on the ISS since June, has experienced weight loss during her extended mission, prompting NASA to ramp up nutritional support efforts. Initially scheduled for an eight-day mission, Williams, 59, and her fellow astronaut Barry Wilmore were stranded due to technical issues with the Boeing Starliner.

NASA doctors started working with Williams about a month ago to help her pack on the pounds — even before the viral images caused global concern about her health, a source said.
