Ms Wanza had an operation to enlarge her breasts and later developed complications.
She sought medical attention at Nairobi Hospital on Wednesday and died on Thursday.
The Kenya Medical Practitioners and Dentists Board has named the clinic where a woman had a breast enlargement operation that later resulted in her death.
KMPD Board chief executive Daniel Yumbya identified Surgeoderm Healthcare in Nairobi as the clinic where Ms June Wanza had a cosmetic operation that turned fatal last week.
Mr Yumbya said the board had written to the clinic's management asking for an explanation into the events leading up to her eventual hospitalisation and death at the Nairobi Hospital.
They have also requested for a report from the Nairobi Hospital.
"After we receive the report from Nairobi we will consider the next course of action," said Mr Yumbya.
The clinic, situated along Theta Lane in Nairobi’s Kilimani area, has slick online advertisements detailing a range of cosmetic procedures offered including breast enlargement and reduction, leg shaping or augmentation, hair loss treatments and plastic or reconstructive surgery.
Ms Wanza had an operation to enlarge her breasts and later developed complications. She sought medical attention at Nairobi Hospital on Wednesday and died on Thursday.
With her blood pressure running low, doctors worked to save her after realising that her intestines had been cut or punctured during a botched procedure to enlarge her breasts.
“Her intestines were cut during the cosmetic operation, making all the waste leak and spread within her stomach, which is an infection known as sepsis," a family member said Wednesday.
