Electrolyte Imbalances - electrolyte are essential to the production of the body's "natural electicity" that ensures healthy teeth, joints and bones, nerve and muscle impulses, kidneys and heart, blood sugar levels and the delivery of oxygen to the cells.

Hyponatremia (related to "water-loading") - as stated above, electrolytes are essential to proper body functioning. Drinking too much water (more than eight, eight-ounce glasses in less than twelve hours), can cause Hyponatremia (not enough sodium in the blood), especially in someone already malnurished or dehydrated. Hyponatremia can cause fluid in the lungs, the brain to swell, nauseousness, vomiting, confusion and even death.

Refeeding Syndrome (related to treatment) - Starved or severely malnourished patients can undergo life-threatening fluid and electrolyte shifts following the initiation of agressive nutritional support therapies. This phenomenon is known as "refeeding syndrome" and can occur in patients receiving either enteral (tube feeding) or parenteral (intravenous feeding) nutritional support. To avoid the development of the refeeding syndrome, nutrition support in patients at risk should be increased slowly while assuring adequate amounts of vitamins and minerals. Organ function, fluid balance and serum electrolytes (especially phosphorus, potassium and magnesium) need to be monitored daily during the first week and less often thereafter.

Lanugo - (soft downy hair on face, back and arms). This is caused due to a protective mechanism built-in to the body to help keep a person warm during periods of starvation and malnutrition, and the hormonal imbalances that result.

Edema - swelling of the soft tissues as a result of excess water accumulation. It is most common in the legs and feet of Compulsive Overeaters and in the abdominal area of Anorexics and/or Bulimics (can be caused by Laxative and Diuretic use).

Muscle Atrophy - wasting away of muscle and decrease in muscle mass due to the body feeding off of itself.
Impaired Neuromuscular Function - due to vitamin and mineral deficiencies (specifically potassium), and malnutrition.

Paralysis - transient (or temporary) paralysis -- extreme weakness of muscles or not being able to move at all -- Caused by low levels of potassium, and/or the degeneration of nerve cells, in the spinal cord or in the brain, which have been deprived of essential nutrients. Left untreated, periods of paralysis may happen more frequently and more severly, lead to permanent muscle weakness, and even result in death.

Tearing of Esophagus - caused by self-induced vomiting
Mallory-Weiss tear - associate with vomiting, a tear of the gastroesophageal junction
Gastric Rupture - spontaneous stomach erosion, perforation or rupture.
Gastrointestinal Bleeding - bleeding into the digestive tract.

Esophageal Reflux - Acid Reflux Disorders - partially digested items in the stomach, mixed with acid and enzymes, regurgitates back into the esophagus. This can lead to damage to the esophagus, larynx and lungs and increases the chances of developing cancer of the esophagus and voice box.
Reflux can sometimes become severe enough that food cannot be kept down at all and medical attention should be sought immediately.
Barrett's Esophagus - associated with Cancer of the esophagus and caused by Esophageal Reflux, this is a change in the cells within the esophagus.

Cancer - of the throat and voice box (Larynx) due to acid reflux disorders.

Insomnia - having problems falling and/or staying asleep.
Chronic Fatigue Syndrome - continuous and crippling fatigue related to a weakened immune system.

Hyperactivity - manic boughts of not being able to sit still.

Swelling - in face and cheeks (following self-induced vomiting).

Callused or bruised fingers - this is caused by repeated using the fingers to induce vomiting.

Dry Skin and Hair, Brittle Hair and Nails, Hair Loss - cause by Vitamin and Mineral deficiencies, malnutrition and dehydration.

Low Blood Pressure, Hypotension (more common in those with Anorexia and/or Bulimia) - cause by lowered body temperature, malnutrition and dehydration. Can cause heart arrythmias, shock or myocardial infarction.

Orthostatic Hypotension - sudden drop in blood pressure upon sitting up or standing. Symptoms include dizziness, blurred vision, passing out, heart pounding and headaches.

High Blood Pressure, Hypertension (more common in those with Compulsive Overeating and/or Binge Eating Disorder) - elevated blood pressure exceeding 140 over 90. Can cause: blood vessle changes in the back of the eye creating vision impairement; abnormal thickening of the heart muscle; kidney failure; and brain damage.

Low Platelet Count or Thrombocytopenia -
Caused by low levels of vitamin B12 and Folic Acid, and/or by excessive alcohol. It may also be an indication of a suppressed immune system or immune dysfunction.

Disruptions in Blood Sugar Levels -
Low Blood Sugar/Hypoglycemia: can indicate problems with the liver or kidneys and can lead to neurological and mental deterioration.

Elevated Blood Sugar/Hyperglycemia - can lead to diabetes, liver and kidney shut down, circulatory and immune system problems.

Diabetes - high blood sugar as a result of low production of insulin. This can be caused by hormonal imbalances, hyperglycemia, or chronic pancreatitis.

Ketoacidosis - high levels of acids that build up in the blood (known as ketones) caused by the body burning fat (instead of sugar and carbohydrates) to get energy. It can be a result of starvation, excessive purging, dehydration, hyperglycemia and/or alcohol abuse (it can also be a result of uncontrolled or untreated diabetes). It can lead to coma and death.

*You do not need to be diabetic or alcholic to end up with Ketoacidosis!

Iron Deficiency, Anemia - this makes the oxygen transporting units within the blood useless and can lead to fatigue, shortness of breath, increased infections, and heart palpitations.

Kidney Infection and Failure - your kidneys "clean" the poisons from your body, regulate acid concentration and maintain water balance. Vitamin Deficiencies, dehydration, infection and low blood pressure increase the risks of and associated with kidney infection thus making permanent kidney damage and kidney failure more likely.

Osteoporosis - Thinning of the bones with reduction in bone mass due to depletion of calcium and bone protein, predisposing to fractures.
Osteopenia - Below normal bone mass indicating a calcium and/or vitamin D deficiency and leading to Osteoporosis.
* Hormone imbalance/deficiencies associated with the loss of the menstrual cycle can also increase your risks of Osteoporosis and Osteopenia.

Arthritis (degenerative) - can be caused by hormonal imbalances and vitamin deficiencies as well as increased stress on the joints in individuals who suffering Compulsive Overeating.

TMJ "Syndrome" and Related TMJ Problems - degenerative arthritis within the tempero-mandibular joint in the jaw (where the lower jaw hinges to the skull) creating pain in the joint area, headaches, and problems chewing and opening/closing the mouth. Vitamin deficiencies and teeth grinding (often related to stress) can both be causes.

Amenorrhea - Loss of Menstrual Cycle (due to lack of secreting hormone, Oestrogen, by the ovaries). Loss of the menstrual cycle can also lead to Osteopenia and Osteoporosis.

Easily Bruising Skin - Vitamin Deficiencies that decrease the body's ability to heal itself, low blood pressure, low platelets count and/or extreme weight loss will all lead to easily bruised skin that can take a long time to heal.

Dental Problems, Decalcification of teeth, erosion of tooth enamel, severe decay, Gum Disease - will be caused by stomach acids and enzymes (from vomiting); vitamin D and calcium defiencies, and hormonal imbalance. Can also be due to the lack of exercise the teeth can get from the process of eating certain foods. Dental problems can sometime indicate problems with the heart.

Liver Failure - the liver aids in removing waste from cells, and aids in digestion. You cannot live without your Liver. Fasting and taking acetaminophen (drug found in over-the-counter pain killers) increases your risks for Liver damage and failure. Loss of menstruation and dehydration (putting women at risk for too much iron in their system), and chronic heart failure can lead to liver damage or failure.

Bad Circulation, Slowed or Irregular Heartbeat, Arrhythmias, Angina, Heart Attack - There are many factors associated with having an Eating Disorder that can lead to heart problems or a heart attack. Sudden cardiac arrest can cause permanent damage to the heart, or instant death...
electrolyte imbalances (especially potassium deficiency), dehydration, malnutrition, low blood pressure, extreme orthostatic hypotension, abnormally slow heart rate, electrolyte imbalances, and hormonal imbalances call all cause serious problems with the heart, high blood pressure, accumulation of fat deposits around the heart muscle, high cholesterol, decreased exercise due to lack of mobility, diabetes and hormonal imbalances can all lead to serious problems with the heart.

Infertility - the inability to have children. Caused by loss of menstrual cycle, and hormonal imbalances. Malnutrition and vitamin deficiencies can also make it impossible to succeed with a full-term pregnancy, and can increase the chances significantly of a baby born with birth defects.
Polycystic Ovarian Syndrome - a study a few years ago suggested that people with Eating Disorders were at an increased risk for developing Polycystic Ovarian Syndrome (PCO), and that recovery from the Eating Disorder should be part of treatment for PCO.

Problems during pregnancy - including potential for high risk pregnancies, miscarraige, still born babies and death or chronic illness from minor to severe, in children born (all due to malnutrition, dehydration, vitamin and hormone deficiencies).

Depression - mood swings and depression will all be cause by physiological factors such as electrolyte imbalances, hormone and vitamin deficiencies, malnutrition and dehydration. Living with the Eating Disorder behaviors themselves will cause depression.
Depression can also lead the sufferer back into the cycle of the Eating Disorder (or may have initially been the problem before the onset of the ED). Stress within family, job and relationships can all be causes. There are also a percentage of people born with a pre-disposition to depression, based on family history.
Can lead to Suicide

Lowered body temperature - Temperature Sensitivity - caused by loss of healthy insulating layer of fat and lowered blood pressure.

Cramps, bloating, constipation, diarrhea, incontinence - increased or decreased bowel activity.

Peptic Ulcers - aggrivated or made more severe by increased stomach acids, cigarette smoking, high consumption of caffeine or alcohol

Pancreatitis - this is when the digestive enzymes attack the pancreas. It can be caused by repeated stomach trauma (such as with vomiting), alcohol consumption or the excessive use of laxatives or diet pills.

Digestive Difficulties - a deficiency in digestive enzymes will lead to the bodies inability to properly digest food and absorb nutrients. This can lead to malabsorption problems, malnutrition and electrolyte imbalances. Diseases that may be triggered by a history of an Eating Disorder include: Celiac Disease (gluten sensitivity), and Crohn's Disease

Weakness and Fatigue - caused by generalized poor eating habits, electrolyte imbalances, vitamin and mineral deficiencies, depression, malnutrition, heart problems.

Seizures - the increased risk of seizures in Anorexic and Bulimic individuals may be caused by dehydration, hyperglycemia or ketoacidosis. It is also possible that lesions on the brain caused by long-term malnutrition and lack of oxygen-carrying cells to the brain may play a role. SOME type of antidepressants can increase the risk of seizure and usually carry a warning against prescribing them to people with Eating Disorders, unless the benefits significantly outweigh the risks.

Death caused by any of the following or any combination of the following: heart attack or heart failure; lung collapse; internal bleeding, stroke, kidney failure, liver failure; pancreatitis, gastric rupture, perforated ulcer, depression and suicide.
