Your parents' health can be better analysed with their birth/natal charts and a generic view can only be provided based on your chart.
As per your chart, there may not be any major health issues with your parents. Your father's health will need to be taken care for any deviations. Your mother could have less energy in the body and would be healthy enough and she may not reveal her issues, if any, which you may require to keep in check.
Best Wishes.
