Ulrika has always been on the thin side. I think she mentioned she is a stone under her normal weight. She does look gaunt.
I am sure she has just been drinking from a Gaviscon bottle, she may have an ulcer, or even something as simple as a nervous stomache.
She runs around after a toddler, and her daughter suffers ill health. She does not have to be ill to be thin. Stress and keeping busy can do it.
