Eating disorders and diabetes? Need answers please...?

I am curious to find out if eating disorders, such as bulimia or anorexia, or even crash dieting alot, can cause problems such as diabetes. I know that they have many undesireable side effects. I have a great friend who I know has been struggling with weight issues and has been using laxatives, diuretics, and some weight loss pills for a year or so now. I know she's thrown up after many many meals. sometimes everything she eats in a day (on a drunken depressed binge one day she spilled it to me). Now she's been having problems losing wieght, been having stomach problems and lethargy, and she has been having many many episodes of low blood sugar, and every now and then high blood sugar. Someone said she could have screwd up her kidneys or something and caused type II diabetes or something like it. Is this possible? I worry about her. Any advice on any of this could really help me to get her to understand how sick she really could be....

You should try to get her into therapy so she can get over the eating disorder. That should be your biggest concern.

Eating disorders could probably affect diabetes, I'm not really sure. I have heard of "diabulimia", which is when type 1 diabetics don't take insulin to lose weight, but that wouldn't be the problem here.

The only thing you can really do is make sure she gets the appropriate help! Good luck.

i think she should see a doctor . if she is having stomach cramps and low and high blood sugar levals as these are sighs of diabetes

Kidney problem do not cuase diabetes; however, diabetes can lead to kidney problem.
Anorexia can lead to metabolic problem. Hypoglycemia (low blood sugar would be one of them), but not causing diabetes.
Diabetes type II is due to cell receptor to insulin to take up glucose.
Bulimia can lead to electrolyte imbalance and lead to alkalosis. Ph affects the brain.
Ketoacidosis may be related to diabetes type I, alcohol, hyperglycemia in DM II, and dehydration and can cause lethargy and commatose among other things when the body is deprived of glucose and have to use fat. Fat byproduct is ketone body which is acidodic. Compensation of acidocis is through rapid and labored breathing to excrete co2 (kussmaul's breathing).
laxatives, dueretics, and weight loss pills often cause fluid loss. This also upsets the electrolytes and lead to electrical conduction of the brain neurons, heart, muscles, and others. It can also lead to dehydration.
Treat the cause, do not treat the symptoms alone.
Your friend has to go to ER so they can do a blood draw to determine the type of pH and BMP to measure electrolytes. Very sad. :(
