Can a healthy, anorexic woman (5'1'', 75 lbs, never exercises) be forced to have a feeding tube?

Hi, If an anorexic is a female who's 5' 1'' tall, 75 lbs and never exercises, can someone place a 5150 hold on her or put her in a hospital or treatment center against her will? I hope that's impossible. If she doesn't eat or drink a supplement drink in a hospital or treatment center, can she be forced to have a feeding tube? I hope not. If she is only tube fed, how many calories does she receive daily from the feeding tube? I hope it's less that 800 calories. Can she just receive nutrition from an I.V drip if she doesn't eat or drink a supplement drink in a hospital or treatment center? She is an anorexic who's 5' 1'' tall, 75 lbs and never exercises. Also, she never eats more than 340 calories a day, but she drinks 4 cans of soda a day (not diet soda), and she doesn't have any health problems. Are there any free, no cost hospitals or eating disorder treatment centers in north GA? I hope not. If there are, could you give me their names and contact info? Sincerely, Chris
