Ramos was born in La Unión, a middle-class neighborhood in Montevideo,[1] the daughter of former footballer Luis Ramos, who played for the Uruguay national team at the 1966 FIFA World Cup in England and Elsa Arregui, an athlete and gym teacher.

Ramos had felt ill after walking the runway and subsequently collapsed unconscious on her way back to the dressing room.

In the wake of Ramos' death, the Madrid Fashion Week (held in September 2006) set a minimum BMI of 18 for all models.

[3] In December that year, Italian fashion designers banned size zero models from walking down their catwalks.

[citation needed] On February 13, 2007, Luisel's 18-year-old sister Eliana Ramos, also a model, died at her grandparents' home in Montevideo of an apparent heart attack,[5] believed to be related to malnutrition.
