A complex variety of factors influence the development of anorexia. Reasons for developing anorexia can be different for each person and may include genetics, past trauma, other mental health conditions such as anxiety and depression. People at the highest risk of developing anorexia include females in their teenage and young adult years, although men and older women are also at risk 1 , 2.
No single test can identify the disorder, as many factors need to be considered to make a formal diagnosis. Purging is a common characteristic of anorexia. Purging behaviors include self-induced vomiting and the over use of certain medications like laxatives or diuretics.
It can also include the use of enemas. Using large amounts of laxatives is another form of purging. These medications are taken in an attempt to decrease food absorption and speed up the emptying of the stomach and intestines. Similarly, diuretics are often used to increase urination and reduce body water as a means to lower body weight. Purging can lead to many serious health complications 4.
Purging is the practice of self-induced vomiting or the use of certain medications to reduce calories, avoid food absorption and lose weight. Constant worry about food and the close monitoring of calorie intake are common characteristics of anorexia. People with anorexia might record every food item they consume, including water. Sometimes, they even memorize the calorie content of foods. Worry over gaining weight contributes to obsessions with food.
Those with anorexia may decrease their calorie intake dramatically and practice extreme diets. Some may eliminate certain foods or entire food groups from, such as carbohydrates or fats, from their diet. If someone restricts food intake for a long period, it can lead to severe malnutrition and nutrient deficiencies , which can alter mood and increase obsessive behavior about food 5 , 6. Decreased food intake can also affect appetite-regulating hormones, like insulin and leptin.
This can lead to other health problems such as bone-mass loss, as well as reproductive, mental and growth issues 7 , 8. Excessive concern about food is a hallmark of anorexia. Practices may include logging food intake and eliminating certain food groups due to the belief that those foods may increase weight. People who are diagnosed with anorexia often have symptoms of other conditions as well, including depression, anxiety, hyperactivity, perfectionism and impulsivity 9. These symptoms can cause those with anorexia to not find pleasure in activities that are usually enjoyable for others 9 [15].
Extreme self-control is also common in anorexia. This characteristic is manifested by restricting food intake to achieve weight loss 10 , Also, individuals with anorexia might become highly sensitive to criticism, failure and mistakes But despite one's best intentions, when the moment for decision comes, that chocolate lava cake is often too enticing and self-control vanishes.
This behavior is normal because hunger increases the intensity of food rewards. Yet, individuals with anorexia nervosa AN , despite their state of starvation, are able to ignore such food-related rewards. A new study by Dr. Christina Wierenga, Dr. Walter Kaye, and colleagues, published in the current issue of Biological Psychiatry, sheds new light on the brain mechanisms that may contribute to the disturbed eating patterns of anorexia.
They examined reward responding in relation to metabolic state hungry or satiated in 23 women recovered from AN and 17 healthy women without eating disorder histories e. Women with active AN weren't studied to reduce potential confounds related to starvation.
The healthy women, when in a state of hunger, showed increased activity in the part of the brain that motivates the seeking of reward, but the women recovered from AN did not. The recovered women also exhibited increased activation of cognitive control circuitry regardless of metabolic state. Use precise geolocation data. Select personalised content.
