Summary
Bariatric surgery may negatively impact bone health, leading to metabolic bone disease and reduced bone mineral density (BMD). Further long-term studies are needed to fully understand these risks.
Area of Science:
- Endocrinology
- Orthopedics
- Metabolic Surgery
Background:
- Bariatric surgery is increasingly performed for obesity management.
- Potential risks include metabolic bone disease and reduced bone mineral density (BMD).
Purpose of the Study:
- To systematically review existing literature on the association between bariatric surgery and bone metabolism.
- To evaluate the risk of metabolic bone disease and BMD changes post-surgery.
Main Methods:
- Systematic review of case-control and cohort studies.
- Searched MedLine database (1997-2009) using keywords: bariatric surgery, osteoporosis, fracture, bone diseases, metabolic.
- Included six studies (four cohort, two case-control).
Main Results:
- Bariatric surgery is linked to altered bone metabolism.
- Evidence suggests a loss of bone mass and increased fracture risk.
- Evaluated studies had a maximum follow-up of two years.
Conclusions:
- Bariatric surgery is associated with adverse effects on bone health.
- Longer-term studies are necessary to comprehensively assess the impact on bone metabolism and fracture risk.

01:31Osteoclasts in Bone Remodeling
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 bone...
01:29Bone Disorders
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...

01:40Bone Remodeling
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.
01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...
