Her flatmates advised her to call an ambulance, but the student insisted several times it was not unusual for her to feel that way and that her symptoms would pass.
One of her housemates left her phone on 'loud' so Miss Houston could call in the night if she felt worse, Leeds Coroner's court was told.
The other student went to check on her sick housemate in the morning, but said she did not see her in her bedroom.

Miss Houston apparently texted her friend later in the day, but she was discovered at 4.30pm by two of her flatmates, lying between her bed and the wardrobe at their home in Hyde Park, Leeds, the court heard.
Paramedics were called and pronounced her dead at the scene at around 5.15pm on Tuesday, September 25.
A post-mortem examination carried out by Dr Lisa Barker, a consultant histopathologist at St James’s Hospital in Leeds, could not determine the cause of death.
Coroner David Hinchliff said: 'As things stand at the moment, we do not have any medical history.
'No cause of death is available at this stage and additional tests will need to be made to assist in finding the cause of death.'
'An adjournment will be made for that purpose and for further enquiries to be made.'

A cremation order was made and an interim death certificate was issued to allow a funeral to take place while the court awaits toxicology and other results.

A Leeds University spokesperson said: 'We were sorry to learn of the death of one of our students.
