Bariatric surgery improves obesity comorbidities but negatively impacts bone health. Understanding the complex mechanisms behind bone loss is crucial for developing effective interventions.
Area of Science:
- Endocrinology
- Orthopedics
- Metabolic Disorders
Background:
- Obesity is a significant global health issue with high morbidity.
- Bariatric surgery is increasingly performed to manage severe obesity and its associated conditions.
- While beneficial for comorbidities, bariatric surgery poses risks to bone health.
Purpose of the Study:
- To investigate the detrimental effects of bariatric surgery on bone health.
- To explore the complex and heterogeneous pathophysiological mechanisms underlying bone deterioration post-surgery.
- To identify factors that could inform therapeutic strategies for mitigating bone loss.
Main Methods:
- Literature review of studies on bariatric surgery and bone health.
- Analysis of pathophysiological pathways affecting bone metabolism after bariatric procedures.
- Synthesis of current knowledge on obesity-related comorbidities and their interaction with bone health.
Main Results:
- Bariatric surgery effectively resolves or improves many obesity-related comorbidities.
- Significant negative impacts on bone mineral density and bone quality are observed post-surgery.
- The mechanisms involve altered nutrient absorption, hormonal changes, and inflammatory processes.
Conclusions:
- Bariatric surgery presents a dual effect, improving metabolic health while compromising skeletal integrity.
- Further research into the heterogeneous mechanisms is essential for clinical practice.
- Developing targeted interventions is necessary to protect bone health in patients undergoing bariatric surgery.

Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...
Hormones and Bone Tissue
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...
Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...
