Osteoporosis and Anorexia Nervosa: The Relationship Between Bone Health and Eating Disorders
Individuals with anorexia nervosa often experience low bone density and weakened bones, increasing their susceptibility to fractures. This decline in bone density can be attributed to various factors associated with hormonal changes resulting from severe weight loss. Anorexics typically exhibit reduced levels of insulin-like growth factor I (IGF-1), a hormone crucial for bone development, while their levels of the steroid cortisol are elevated. In women, this hormonal imbalance leads to a decrease in estrogen production, which normally plays a protective role against osteoporosis. Additionally, inadequate nutrition and diminished muscle mass in females can further contribute to decreased bone density. Similarly, men with anorexia nervosa may also experience low bone density due to hormonal imbalances, weight loss, and malnutrition.
Bowel Problems in Eating Disorder Patients
Eating disorder patients often encounter gastrointestinal (GI) symptoms, such as bloating, abdominal pain, and constipation. These symptoms arise from various disordered eating behaviors, including self-induced vomiting, laxative abuse, and food restriction. Unfortunately, these behaviors can have detrimental effects on the digestive system, damaging the bowel muscle and nerve endings. As a result, permanent constipation and occasional abdominal pains may occur. Furthermore, chronic under-eating can cause the muscles of the small and large intestine to shrink, leading individuals with anorexia to experience stomach aches, bloating, and acid reflux. Additionally, reduced organ size and enzyme production contribute to food remaining in the organs for extended periods compared to normal digestion.
