“I have anorexia but it is not the type where I dislike eating, but the type where my body rejects food. My body is malnourished and cannot absorb nutrients because I throw up when I eat. It is so serious that I had to be warded in the ICU," explained Constance, who was known in the '90s for her roles in erotic movies. 

"My potassium level is also super low. It was only 1 [millimoles per litre of blood], while the normal range is between 4 to 6. I was given lots of intravenous drips and it has since risen to 2. But I still have to remain in the ICU. Don’t worry, I will be strong.”

Though she did not reveal how long she has been battling the eating disorder, she said that she decided to go public about her condition because “if I leave this world, I want my good friends and fans to know my health situation and not read the untruths in reports".

Fortunately, Constance’s condition improved and she was moved to a general ward two days later. Posting photos of her meals, which consisted mainly of porridge, the former actress said she was also eating again, but still had to remain in hospital for observation.

She also shared pics of her bruised arm, a result of the many blood tests she had to take, adding that she could not be discharged until her potassium levels were in the safe range.

Life after showbiz hasn't always been smooth for Constance. 

The former actress joined TVB after winning a radio competition in 1988 and made her TV debut in 1989 period drama Ode to Gallantry, which starred Tony Leung. She left the Hongkong broadcaster after three dramas and began working in Category III movies.

When she was furthering her career in Taiwan, she caught the eye of Taiwanese millionaire Wong Ren Zhong and reportedly became his 'god daughter'. Sadly, she found herself struggling financially after he passed away in 2004 and she was spotted working the night shift at a Hongkong fast food restaurant in 2014 to make ends meet.
