Rapid Weight Loss and Gain Caused Female Hair Loss?

(female) I have been on Topamax 200mg twice a day for over a year now, I have also been taking Ritalin 20mg twice a day for the same lenght of time, and taking Xanax 2mg three times a day and Baclofen 20mg three times a day for about six months. I have also had a problem with anorexia and Bulimia for quite a number of years now and been up and down on my weight from about 72 pounds to around 145 to being stable at around 90 pounds for quite awhile now. I am a strick vegetarian and am now taking 65mg of iron twice a day and drinking a protien drink every morning. But for about the last four months my hair has been falling out all over the place, it falls out when I shower,in my sleep, when I run my fingers through it, blow dry it, brush it, on my clothes, ect..I am taking all the vitimans I can think to take but it just keeps falling out…and I had stopped taking my medications to see if that was the problem but it hasn’t helped. Could you please advise any helpful information on what I can do to stop the hair loss and get it to regrow, your help would be greatly appreciated.

You have “been there and done that” with things that are known to cause hair loss, including the medications, severe changes in diet with weight loss, and dietary problems that could lead to a variety of vitamin deficiencies (too many to list here). These stem from your weight problems. Looking over your list, I would not know where to start. I think that you should find a good doctor that you trust and can form a bond with, and then tackle your hair loss problem as a matter of focused attention. This is not something for internet medicine. I wish I could offer more, but I’m limited to what I can do through text on a screen.
