What is the link between atheletes/models/etc and binge-eating disorders?

---

I read somewhere that atheletes and models- or any other professionals whose bodies are on "public display on a frequent basis"- notably struggle with binge-eating disorders where they rapidly and excessively consume foods at certain periods of time, usually due to depression, anxiety, boredom, etc.

It seems sort of odd to me that this is the case, considering atheletes and models are usually very slender.

What do you guys think are some of the links?
You are asking about two very different groups of people.

When it comes to elite level athletes, yes, there are certain sports where eating disorders are a big problem. It has less to do with "bodies on display" than with "if I lose 5 kg I'll shave 5 seconds off my time" or similar. You can, for example, look into ski jumping, where a minimum BMI has been set due to jumpers losing as much weight as they can - to unhealthy low lovels - to be able to fly further on their jumps.

Models are on public display, but they also have to maintain a certain body type as their role is a living hanger for the clothes. Unlike with (most) athletes, models can and do use illicit drugs to keep their weight down.

Now there will be binging and purging in both groups, but I do not know to what extent it exists.  (+ info)

What does getting bit by a tic and gaining weight have to do with eachother?

---

This girl said she got really big because she got bit by a tic and she got lyme disease, which caused her to gain weight.
I don't understand....I didn't think lyme disease made you fat. Do you just wake up one day and youre huge??
I know that for me, before I got sick 3 years ago, I used to walk 3 miles a day, work 25 hours a week at a job that rarely allowed me to sit and I had so much to do on days off, that I ate only small amounts as I was so busy. Now, in the condition I am in with chronic severe lyme, I can only walk 1/4 mile a day, I am disabled and cannot work and have had a series of secondary infections that has left me with no energy, a great deal of pain and fatigue and a very sedentary life. Lyme disease did not cause the weight gain. The symptoms of the disease changed my life so severely that my activity level is dramatically less...causing me to gain weight. I still try and push myself and watch my diet but I just don't have the activity level i once had.  (+ info)

How many personality disorders can a person have?

---

I am just curious,l how many personality disorders can one person have? Can someone have borderline, narcissistic, and paranoid personality disorders at the same time? Or more even?
I know some of them have qualities that relate somewhat but if the person meets the criteria entirely for more than one of them do doctors diagnose them with multiple disorders?

thanks!
A person will only be diagnosed with on personality disorder. If they have traits of several they will be diagnosed PD NOS or given a cluster diagnosis.
A person that has both Borderline and Narcissistic traits is most likely an anti-social PD.  (+ info)

What are some dermatological genital disorders?

---

I have oral and genital sores that test negatively for any STD's. I've read a little about Behcet's disease and am researching other genital skin disorders.
I just typed in my search bar "derrmatological genital disorders" and went to site #1 - Genital Skin Problems.Derrm.Net NZ. They have a whole list of genital disorders that you can click onto and they also show pictures. I looked at Behcet's disease and it stated that in the U.S. only about 1 in 20,000 get that disease and it also showed photos. Why don't you go to this site and look up each one. Maybe you can find out what you have. I hope this helps you. Good Luck!  (+ info)

What mental disorders are strictly genetic?

---

I have to do a research paper for school and i wanted to know what mental disorders are strictly genetic. I was going to do something like schizophrenia or bipolar. However as some of you may know, these disorders are highly debated whether they are genetic or acquired.
none that are 100% proven to be genetic, although there can be some genetic factors. Honestly, it's a mix of lots of things. Think about it: if evolution and natural selection did happen what would be the benefit in a genetic mental disorder?

here are some that are thought to have some genetic factors:
Depression
Postpartum depression
Schizophrenia
Dysthymia
Delusional disorder  (+ info)

How do people die from eating disorders?

---

Mainly anorexia nervosa and bulimia nervosa. I have been doing research on the two eating disorders and I would like to find out what others have to say or think about the two.
The pictures that I've seen are haunting me!
Usually anorexic people die from organ failure (kidneys, liver, etc.) because they are not sustaining enough in their diet to provide what the body needs. Lack of protein also can cause lack of concentration and other problems with the workings of the brain.  (+ info)
