For people with a history of an eating disorder, reading about bingeing and purging may be a trigger for them. People can binge on any type of food, although typically high-fat and high-carbohydrate foods are used, both because of their "forbidden" nature, particularly to those who are concerned about their body weight, and because of the concern they cause when eaten.
Common binge foods include:. There are several different types of purging that people use to attempt to remove the excessive food they have eaten. The most commonly recognized form of purging is self-induced vomiting where the person will stimulate the gag reflex by putting their fingers down their throat to induce vomiting or they will drink salty water or another substance to induce vomiting. Exposure of the teeth to the stomach acid in vomit can also cause irreparable damage and tooth decay.
Another type of purging is self-induced diarrhea. This is typically achieved by using laxatives to clear out the lower part of the digestive system. Diarrhea is also harmful to the digestive system, causing dehydration and malabsorption of vitamins, and over time, risking constipation if laxatives are over-used. A less well-recognized form of purging is excessive exercise. Exercise is typically considered to be a healthy behavior, particularly among people who are overweight or obese, so exercise is rarely discouraged until harm results from it.
Exercising enough to burn off the calories of a binge can take hours per day, resulting in time being taken away from other activities. People who are not taking in enough nutrients through a balanced diet to support the demands on the body of excessive exercise may become malnourished.
And without carefully managing your fluid and mineral intake through the exercise process, you can risk dehydration or hyponatremia. Purging with exercise can also be fueled by the use of stimulant drugs , such as meth and other amphetamines, cocaine , ecstasy or caffeine.
These drugs can give temporary bursts of energy, increase physical and mental alertness and increase the ability to exercise for prolonged periods of time. Typically, these drugs have a rebound effect, resulting in exhaustion after they wear off. Bingeing and purging are not, in themselves, eating disorders , although individually and in combination, they can be symptoms of an eating disorder such as binge eating disorder or bulimia nervosa.

The Effects of Bulimia on Your Body. Exercise Bulimia: Symptoms, Treatments, and More. Medically reviewed by University of Illinois. What is bulimia? Common results of bulimia are swollen eyes and cheeks, caused by pressure as you lean over to make yourself sick.
Vomiting may also cause your salivary glands to swell and the tissues of your mouth and tongue to become dry, red and sore. I actually gained about a stone, and for someone whose mental illness was resulting from a desire to lose weight, this was difficult to stomach.

Katie Couric reveals she battled bulimia Rose replaced bulimia as a stress-coping mechanism with more healthful approaches, such as yoga, mindfulness and writing, she said.
In , she wrote about her experiences with bulimia in the Huffington Post. Though Rose no longer makes herself sick, she said, bulimia remains an ongoing battle. Without her new stress-coping tools in place, there could be a risk of relapsing. Making healthy food choices can be difficult for patients with bulimia; the other study published this week suggests that their brains respond differently to food rewards.
Bulimia's big unanswered question. The study involved 26 women with a history of bulimia and 22 women with no eating disorders, who had their brains scanned in MRI machines while they were given sugar water either after fasting for 16 hours or after eating a breakfast of bagels and cream cheese. The researchers then analyzed the brain images to determine differences in how the women responded to the water's sweet taste when hungry or full.
The researchers found that the brains of women with no history of bulimia showed significantly more activity in the left putamen and amygdala when they were given sugar water after fasting, versus after they were fed.
Those parts of the brain are associated with evaluating rewards, such as how rewarding a taste is, said Alice Ely, a clinical psychologist at Christiana Care Health System in Delaware and lead author of the study.
As for the women with a history of bulimia, there was no such difference, and their left amygdalas had greater activity when fed compared with the other women -- which may hold clues to the binge-eating aspects of bulimia, the study suggests. Ely, who was involved in the study while at the University of California, San Diego, likened the findings to grocery shopping. Artist's sketches convey struggles of eating disorder.
We tend to buy more highly palatable foods," Ely said. You don't get pulled and motivated in a big way by a reward," she said. Limitations of the study include its small sample size, due to the high cost of brain imaging, and the fact that all of the participants with a history of bulimia were recovered or remitted from the disorder, Ely said. Additionally, "we looked specifically at sweet taste, and we know that highly palpable foods come in many forms," such as high-fat types, too.
Still, no one knows whether bulimia causes such changes in the brain or whether such differences in the brain are associated with susceptibility to bulimia, Ely said. Join the conversation. Walter Kaye, who led the study, hopes that that question could be answered as more research is conducted specifically on the brains of bulimics in the future.
Clearly, stress and negative mood states are related to this.
