One often hears statements such as eighty percent of the questions can be answered by twenty percent of the answers, or other similar statements, indicating that a small set of answers are enough to answer most of the questions in a particular topical area. To investigate this statement, a set of 630 questions, which were sent to an on-line service, were analyzed. All the questions were about eating disorders and obesity. The conclusion is that the statement, which was investigated, was not true. There was a large variation of different questions, and even though some questions did appear more than once, it was much less than eighty percent of all questions. The chapter offers insight into different types of questions posted on-line in the area of eating disorders. From the study follows that to provide satisfactory answers to a large part of the questions, it is necessary to have humans answering the questions.

To get an overview of which are the most common questions, which people ask about eating disorders, this study is based on an analysis of 630 questions, which were sent to an on-line question area, where people with different psychological problems could send their questions and get free answers by an expert psychologist. 630 questions will of course not cover every question anyone may ask about eating disorders, but it will probably give a good basis for a main organisation of such a book or web site.
Eating disorders are a common set of psychiatric disorders, where a person eats too little (anorexia nervosa), too much (binge eating disorder) or too much combined with compensatory activities like purging and fasting (bulimia nervosa). In the worst cases, these disorders can lead to death, but more commonly causes unhappiness and unhealthy eating. There are no reliable statistics on the incidence of eating disorders, because most people suffer in secrecy and do not come into contact with health care providers. Some studies indicate that between 10 and 35% of young women suffer from bulimia nervosa, severe anorexia nervosa was in another study found for about 1% of teenage girls. 70% of people suffering from eating disorders are women (Beat, 2007). Web4Health is a web site originally developed with support from the European Community (Web4Health, 2011). It contains about one thousand informational texts about different psychological problems. The site is meant to answer questions about psychology, psychiatry and psychological questions. Most of the texts are available in German, English and French, some of them also in Greek, Italian, Finnish and Polish. The Web site was first opened in 2004. It has about 600 000 visitors a month.
On the web site is an area where people can send in questions and get personally tailored answers by a human expert. This service is presently available in German and Swedish, but was until April 2008 also available in English. This study is based on a collection of 12622 such questions in Swedish and English. German questions were not used for this study. Of these 12622 questions, 630 or 5% were found to relate to the area of eating disorders and therefore selected. This selection of 630 questions is the basis for this chapter.
These 630 questions were first roughly categorized into four categories: Anorexia nervosa, bulimia nervosa, binge eating/overweight and other/unspecified eating disorder. However, many questions did not fit very well in these four category groups, and they were then assigned to the group which was closest to their problem. According to this rough classification, the questions had the distribution shown in Table 1.
