We have analysed both the charts of yours and that of your mother's. As a matter of policy we do not comment on other astrologers' comments.
As per the chart analysis, no such indications can be seen with respect to your mother. The current time till July 2022 calls for a little care on the health front which could be something quite minor and you can rest assured, that your mother would be hale and hearty.
If the requirement is felt, please have a professional medical check up, otherwise be happy and cheer up.
