A couple finally got their first child 11 years into their marriage, but the new mother slipped into a coma after giving birth to her premature baby daughter.
The 36-year-old woman had suddenly fallen ill last Tuesday (July 18) and developed a fever.
Her 32-year-old brother told reporters she thought it was a common flu, but went to see a gynaecologist.
However, her conditions did not improve after that.
The man said his sister felt nauseous on Tuesday and vomited many times.
She visited a gynaecologist who discovered her blood pressure was abnormally high, while the foetus's heartbeat was slower than usual.
She was immediately conveyed to KK Women's and Children's Hospital, reported Lianhe Wanbao.
He said: "The doctors told my sister that they had to do a C-section immediately to remove the baby or both she and the baby would be in danger."
According to him, the baby was born prematurely and weighed only 800g. She is still warded in the Neonatal Intensive Care Unit (NICU). Fortunately, her conditions have stabilised.
However, the same could not be said for the baby's mother, who was found to have a bacteria infection, which led to a liver failure.
The brother said: "On the day when she gave birth, she was still talking with us, but suddenly became so quiet that evening. She fell into a coma the following evening."
He also revealed that although his sister had suffered from Hepatitis B, she was very healthy before her pregnancy.
The sudden deterioration of her health came as a shock to the whole family, he said.
As she now needs a liver transplant in order to stay alive, the family has become worried about finding a suitable donor and the medical costs, said her brother.
