It is a psychological condition in which the subject engages in recurrent binge eating followed by an intentional purging. This purging is done in order to compensate for the excessive intake of the food and to prevent weight gain. Purging typically takes the form of: vomiting inappropriate use of laxatives, enemas, diuretics or other medication excessive exercising fasting Description DSM-IV criteria The following six criteria should be met for a patient to be diagnosed with bulimia[1] [2]: The patient feels incapable of controlling the urge to binge, even during the binge itself, and consumes a larger amount of food than a person would normally consume at one sitting. The patient purges him or herself of the recent intake, resorting to vomiting, laxatives, diuretics, exercising, etc. The patient engages in such behavior at least twice per week for three months. The patient is focused upon body image and desperate desire to appear thin. The patient does not meet the diagnostic criteria for anorexia nervosa. (Some anorexics may demonstrate bulimic behaviours in their illness: binge-eating and purging themselves of food on a regular or infrequent basis at certain times during the course of their disease. Alternativamente, some individuals might switch from having anorexia to having bulimia. The mortality rate for anorexics who practice bulimic behaviors is twice that of anorexics who do not. [3]) The patient is of normal weight or overweight. Please note that, en general, diagnostic criteria are considered a guide. A legitimate clinical diagnosis can be made when the majority of the criteria are met. Patterns of bulimic cycles The frequency of bulimic cycles will vary from person to person. Some will suffer from an episode every few months while others who are more severely ill may binge and purge several times a day. Some people may vomit automatically after they have eaten any food. Others will eat socially but may be bulimic in private. Some people do not regard their illness as a problem, while others despise and fear the vicious and uncontrollable cycle they are in [4].  Subtypes of bulimia The specific subtypes differ in the way the bulimic relieves themself of the binge. Purging type - The purging type uses self-induced vomiting, laxatives, diuretics, enemas, or ipecac, as a mean of rapidly extricating the contents for their body. This type generally is more commonly found, and can use one or more of the above methods on a regular basis [5].  Non-Purging Type - This type of bulimic is very rarely found (only approximately 6%-8%), as it is a less effective means of ridding the body of such a large number of calories. This type of bulimic engages in excessive exercise or fasting following a binge in order to counteract the large amount of calories previously ingested. This is frequently observed in purging type bulimics as well, however this method is not their primary form of weight control following a binge [6].  Consequences of bulimia nervosa Malnutrition Dehydration Electrolyte imbalance Hyponatremia Vitamin and mineral deficiencies Teeth erosion and cavities, gum disease Sialadenosis (salivary gland swelling) Potential for gastric rupture during periods of bingeing Esophageal reflux Irritation, inflamación, and possible rupture of the esophagus Laxative dependence Peptic ulcers and pancreatitis Emetic toxicity due to ipecac abuse Swelling of the face and cheeks Callused or bruised fingers Dry or brittle skin, hair, and nails, or hair loss Lanugo Edema Muscle atrophy Decreased/increased bowel activity Digestive problems that may be triggered, including Celiac, Crohn's Disease Low blood pressure, hypotension Orthostatic hypotension High blood pressure, hypertension Iron deficiency, anemia Hormonal imbalances Hyperactivity Depression Insomnia Amenorrhea Infertility Polycystic Ovary Syndrome High risk pregnancy, miscarriage, still-born babies Diabetes Elevated blood sugar or hyperglycemia Ketoacidosis Osteoporosis Arthritis Weakness and fatigue Chronic Fatigue Syndrome Cancer of the throat or voice box Liver failure Kidney infection and failure Heart failure, heart arrhythmia, angina Seizure Paralysis Potentially death caused by heart attack or heart failure; lung collapse; internal bleeding, Golpe, kidney failure, liver failure; pancreatitis, gastric rupture, perforated ulcer, depression and suicide.
