Miko had to end her last stream early due to health reasons. She seemed in bad shape.

What we know so far:
>Has to visit hospital every 3-6 months
>Has been hospitalized several times
>Mentioned that it is unrelated to COVID-19
>When she went on a 3 month break Cover made a statement in which they mentioned the illness is of chronic nature
>Mentioned in a tweet that she has a congenital illness
>Recently had a medical check-up at the hospital which took 3 days
>Said results were bad due to lifestyle
>Mentioned in today's tweet that she couldn't continue her stream due to anemia


Various chronic diseases are very sensitive to lifestyle. Any MDs here that can narrow it down? Any rrats?
