In a statement based on a coroner’s report, and released by Dr Okoye’s personal assistant, it said her “sudden death” was caused by a subarachnoid haemorrhage.
According to the NHS, this is an uncommon type of stroke caused by bleeding in the space between the brain and thin tissues that surround the brain.
The condition was caused by an aneurysm and “can happen for no apparent reason”, the statement read.
A family spokesperson said: “We are devastated, and our hearts are broken that her beautiful, full life has been cut so short.
“As a family, our priority right now is to take care of her young daughter and continue her legacy and keep her memory alive. A private celebration of her life will be held in the coming weeks.”
Dr Okoye ran two London dental practices and had her own range of dental products.
According to an online profile of Dr Okoye, she qualified at Guy’s Hospital in London and was an expert in cosmetic dentistry.
She was an honorary clinician at St George’s Hospital in London and clinical director of London Smiling Dental Group.
