I recently read an article in a magazine regarding a new disorder termed "Diabulimia." Supposedly, this is a disorder displayed by women with type 1 diabetes in order to lose weight. The women with type 1 diabetes, who take insulin shots, compared these shots to "injectable fat" and therefore they skip their shots all together.

The reason why this topic is so surprising to me is because I am a type 1 diabetic and have been for almost 17 years and I have gained weight since beginning treatment. What happens to the body when this occurs? Also, if a person tries to treat the "diabulimia," will all the weight that was lost be gained right back when she begins to inject the shots again? What other method of losing weight would you suggest for someone like this? I would never risk my life in order to lose weight, but I would still like to learn about it because it is something I have never heard of. Thank you so much!

I have a one half inch lump inside the back of my leg two inches above my knee (there is no visible mark on the skin). It is not painful or bothersome in any way. An acupuncturist thinks it is a cyst. If it is, what kind might it be, what kind of treatment might I get, and how necessary is it?

1) I read the information on your website about knuckle cracking, and I was wondering if it applies to cracking backs and necks. I know that people often have their backs cracked by friends, etc. because it feels good and seems to relieve tension. Also, when my neck feels tight, I often turn it from side to side until it cracks and feels better. I've heard that chiropractors do some version of this, and call it "realignment." Is this safe? Is there a right or a wrong way to crack a back or neck? Is cracking your back/neck actually therapeutic in some way?

2) As a college student, I sometimes spend long hours reading books or looking at computer screens, and often my neck gets stiff. Like many of my joints that get stiff, sometimes I crack my neck, like I would crack my knees or fingers when they feel stiff. I often wind up doing this several times a day.

My question is, could I do irreparable damage to my spinal system if I continue using this method to soothe a stiff neck? Could I wind up a paraplegic if I continue to crack my neck? Leak spinal fluid, etc.?

1) I've heard that the symptoms for heart attack differ for men and women. Could you please send me info on these differences? Also could you give me some possible diagnosis for a feeling of heaviness in the chest?

2) Is it possible to have a heart attack without knowing you're having a heart attack?

Is sleeping on our left side in any way harmful for the heart (or anything else)? Some people tell me we shouldn't do it and others tell me it's actually better than sleeping on our right side. What's the truth?

Thanks!

I fell on my roller blades yesterday and skinned my knee. Now I'm watching my knee change and I am fascinated by the healing process. Could you explain to me just what is happening?

A couple of months ago I developed a hard, bony growth on my instep. I noticed that the top of my foot was hurting, and when I took my shoe off, there was a red lump the size of a quarter (it's not red all the time, just from rubbing against the shoe). A friend of mine who is a nurse said that it's probably a ganglion cyst and the best thing to do would be to, and I quote, "hit it with something really hard," like a dictionary, or a hammer. It should break up immediately, she told me. She hasn't seen it, by the way — this was over the phone.

I'm surprised that she thinks it's a cyst, because it's awfully hard — I would have just thought that it was a bone spur. What do you think? And is smacking a cyst with a dictionary really the way to go?
