Since your mom is age 53, she would have already transitioned to the last pillar of her bazi. Could you please include her birthtime to accurately decode her bazi?
Due to this year being a Yang Water Dragon, I suspect she's having stomach issues.
Also, do include the house floorplan and mark the bedroom which she's sleeping in. I suspect she could be sleeping where the #5 or #2 star lands there which is the sickness star. Please include the exact direction (to the degrees) of your house. Measure this by standing at the front door and face outside your house. I'm trying to get the flying star reading here.
