Mechanisms by which nutritional disorders cause reduced bone mass in adults

Abstract:
Nutritional disorders that cause bone loss in adults include disordered eating behaviors (female athlete triad and anorexia nervosa), gastrointestinal diseases (celiac sprue, inflammatory bowel disease, and other malabsorption syndromes), alcoholism, and hypervitaminosis A. These disorders exert their effects on bone through a number of mechanisms, including estrogen deficiency. Deficiencies of anabolic hormones may also be important, including insulin-like growth factor I (IGF-I), a nutritionally regulated bone trophic factor. In addition, low weight itself is a risk factor for bone loss and decreased bone formation. Reduced calcium and vitamin D availability, with resultant secondary hyperparathyroidism, is another important mechanism of bone loss in nutritional disorders. This review discusses nutritional causes of reduced bone mass in adults and how nutritional disorders exert deleterious effects on the skeleton.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
