To analyse your mother/father's health from their birth charts would be prudent. It is not clear as to whose birth details are shared. We presume the birth chart details shared are that of yours.

As per your chart, we can say that your parents health would be normal and would also get stabilised gradually. The current ongoing time is volatile and would demand better professional medical care, which you would be already taking care of.

Their health should get recovered gradually in during the year 2023.

Best Wishes.
