Hi ladies, I'm 5ft6 and have reached my lowest weight ever: 46kg. I'm not dieting or anythin and I had some blood tests which didnt show any health problems. Has anyone got any tips for putting on weight please?! Emily

This helps you

Underweight is the condition in which the weight of a person is not proportionate to his height and sex.I think you need this treatment

these type of natural treatments are very beneficial and also have no side effect.

Hmm...

Hi, I think just eat a fully balanced diet, maybe get some eating tips from the doctors? I don't really Know seeing as I try to loose weight, and i'm only 15, but maybe it's what you're eating already thats affecting your weight, like if you drink certain types of drinks of eat certain types of food, so like change something you usually have for something completly different and just try many diferent things, hope it works.
