Boonna Muangcode, 67, originally from Mukdaharn province in north-eastern Thailand, was last seen wearing a blue nightgown. Her feet were bare.
Her son-in-law, Mr Soonthorn, said Ms Boonna went to talk to a neighbour before she disappeared. It was suspected she might have gotten lost in the woods behind her house.
The police and her neighbours have been looking but have found no trace.
“She has a problem with her memory,” Mr Soonthorn said. “But she has never lost her way back home before. We are quite worried because she speaks only the Isarn dialect, so can’t communicate with people in Phuket.”
Ms Boonna also suffers from gout in her legs, which makes it hard for her to walk.
If you have any information about the whereabouts of Ms Boonna please contact Mr Soonthorn 083 141 0247 or 081 739 0469.
