Medical Exam and Height


I know a woman who's 4'7 feet tall (140 cm) and she's worried about going to the medical exam at the consulate because she's worried the doctors might disqualify her because of her height. Her height technically puts her in the dwarf category but she doesn't look like one because she's proportionate. She has never received medical treatment for her height such as growth hormone injections or limb lengthening surgery.

Does anyone know if a short height like that is seen as likely to make her a public health charge or disqualify her as handicapped?

Answers appreciated.
