Abstract:
Chronic gastrointestinal diseases such as inflammatory bowel disease, malabsorption syndromes (e.g., intestinal lymphangiectasia, celiac disease, congenital chloride diarrhea, cystic fibrosis), and postsubtotal gastrectomy state or short-bowel syndrome after extensive bowel resection are related to poor bone health in pediatric patients due to increased risks of low bone mineral density, osteoporosis, and fractures. The pathophysiology of abnormal bone health in pediatric gastrointestinal diseases may present from inflammation to malabsorption. In children with chronic gastrointestinal diseases at high risk of poor bone health, routine evaluation using dual-energy X-ray absorptiometry and appropriate prevention or treatment strategies are needed.

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...
