Summary
Gastrointestinal diseases, including celiac disease and inflammatory bowel disease, can lead to significant bone loss and metabolic changes. This review highlights the complex factors contributing to these bone alterations, often overlooked in patients.
Area of Science:
- Gastroenterology and Bone Metabolism
Background:
- Chronic inflammation and malabsorption in gastrointestinal diseases contribute to bone metabolism alterations.
- Gastrointestinal disease is an underrecognized cause of osteoporosis, osteopenia, and osteomalacia.
Purpose of the Study:
- To review the complex etiology of bone alterations in gastrointestinal diseases.
- To discuss bone changes in celiac disease and inflammatory bowel disease patients with malabsorption.
Main Methods:
- Literature review of studies on bone metabolism in gastrointestinal disease.
- Discussion of multifactorial causes including cytokines and systemic factors.
Main Results:
- Bone alterations in gastrointestinal disease are multifactorial, not solely due to malabsorption.
- Cytokines and local/systemic factors play a complex role in bone formation and resorption.
Conclusions:
- Gastrointestinal diseases significantly impact bone health through complex mechanisms.
- Understanding these mechanisms is crucial for managing bone loss in patients with celiac disease and inflammatory bowel disease.

Bone Disorders
5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

Bone Remodeling
40.8K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Osteoclasts in Bone Remodeling
4.5K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Overview of Protein Metabolism
4.4K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Essential Minerals for Bone Health
6.9K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect 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...
