Medical issues from eating disorders and disordered eating can include effects on the following:
Heart and cardiovascular
Weakened heart muscle, cardiac arrest, arrhythmia, low blood sugar, or hypoglycemia. Changes in blood pressure and pulse. Sudden death.
Muscle loss
Overall loss of muscle mass and strength. When malnourished the body seeks areas to find nutrients and breaks down muscle tissue.
Brain
Shrinking of brain density. Seizure. The brain runs on glucose, when deprived of this the body begins finding this nutrient elsewhere. You may also notice difficulties concentrating, and changes in mood and personality.
Skeletal
Loss of bone density and changes in growth projections. Due to inadequate nutrition and mineral loss, brittle bones are prone to fractures or other injury. Exercise while in a malnourished state can exacerbate bone loss.
Electrolytes
Low sodium or low potassium interferes with the function of organ systems and can lead to dehydration and water retention, muscle weakness, slowed breathing, and cardiac arrest.
Gastrointestinal (GI)
Gastroparesis or slowing of the digestive system is characterized by diarrhea, constipation, bloating, or temporary food intolerances. GI issues result from inconsistency in eating, restriction, binges, and disruption of digestion from purging (vomiting or laxative use). The use of laxatives can cause the intestines and colon to atrophy and become paralyzed. Vomiting can damage the esophagus and cause ulcers and increase esophageal cancer risk.
Kidneys
Loss of kidney function from dehydration and low blood pressure, kidney failure, and kidney stones.
Circulation
Cold extremities, difficulty regulating body temperature due to the heart’s inability to pump blood to extremities. Low temperature is similar to hypothermia.
Skin
Pale complexion, patchy complexion, lanugo, weakened skin that is easily damaged, brittle hair and nails, hair loss.
Hormonal
Reduced growth hormones and sex hormones in both males and females, to pre-pubescent levels. Loss of menses and visible changes in reproductive organs. Infertility, decreased interest in sex, inability to maintain erections.
Liver
Cell death from starvation or fatty liver
Dental
Calcium and mineral deficiencies loosen teeth. A dry mouth from dehydration can increase cavity formation. Damaged enamel from purging.
