Health Consequences of Disordered Eating and Eating Disorders
Eating disorders and disordered eating lead to malnutrition and harmful behaviors. In malnutrition, a person does not consume the right amounts of nutrients needed for health and growth. When the body does not receive the energy it needs from food, it breaks down its own tissues for energy. Early in this process, the body breaks down muscle. This can lead to heart damage and heart failure, which can result in death.
The malnutrition associated with eating disorders and disordered eating can lead to low bone density, dry skin, thin hair, and brittle nails. Lack of nutrition also leads to a weaker immune system and anemia (an insufficient number of red blood cells). Anemia is characterized by weakness, fatigue, and shortness of breath. Long-term dehydration can cause kidney failure and death. Some health consequences associated with eating disorders and disordered eating will go away with treatment, but others will not.
Some eating disorders are characterized by purging, or attempts to rid the body of food. Restricted eating and purging can cause stomach pain, nausea and vomiting, changes in blood sugar, dehydration, blocked intestines, and infections. Vomiting can damage the salivary glands and teeth. Eating disorders can also cause constipation (infrequent or delayed hard, dry bowel movements) and life-threatening emergencies such as stomach rupture.
Mentally and socially, eating disorders and disordered eating can lead to conflict in relationships, withdrawal from activities, and worsening mental health conditions. Eating disorders and disordered eating are often associated with low self-esteem and co-occurring disorders (mental illnesses that occur together). Disordered eating and eating disorders can lead to difficulty concentrating or focusing on things other than food, exercise, and body image. They can also increase anxiety and reduce the ability to manage and cope with daily stressors. Eating disorders can increase a person’s risk for suicide.
