Lilly Downs rolled out of bed in her new apartment and began setting up her morning’s IV fluids, which flow from a tube in her chest into her bloodstream to keep the 20-year-old hydrated.

Next, she crushed and dissolved pills so they could run through a separate tube into her intestines, which absorb the medicine better than her stomach.

The steps Lilly took that October morning are necessary because her stomach stopped working properly following her first bout with COVID-19 four years ago. But her routine also served another purpose: It was content she filmed for a video that she later posted on TikTok, where she has amassed nearly 470,000 followers.
