Does bone structure affect metabolism?
Bone tissue harbors several types of specialized bone cells (osteocytes, osteoblasts, osteoclasts, and chondrocytes) that can secrete factors regulating energy metabolism throughout the body (Table 1).
What are metabolic bone disorders?
Metabolic bone diseases are disorders of bone strength usually caused by abnormalities of minerals (such as calcium or phosphorus), vitamin D, bone mass or bone structure, with osteoporosis being the most common.
Does metabolic syndrome cause low bone density?
The findings suggested both MetS and diabetes are associated independently with lower BMD and higher osteoporosis prevalence in men [48].
Is osteogenesis imperfecta a metabolic disorder?
metabolic bone disease, any of several diseases that cause various abnormalities or deformities of bone. Examples of metabolic bone diseases include osteoporosis, rickets, osteomalacia, osteogenesis imperfecta, marble bone disease (osteopetrosis), Paget disease of bone, and fibrous dysplasia.
Can bone density affect weight?
Body weight is directly associated with bone mineral density (BMD). A low body mass index (BMI) has been identified as an important risk factor for lower BMD and predicts greater bone loss in older age (118, 138) and in younger persons in the absence of menses and/or an eating disorder (113).
What are symptoms of metabolic bone disease?
Typical symptoms of metabolic bone disease include:
- Limping.
- Bowed legs.
- Hard lumps along the legs, spinal column, or jaw.
- Softening and unusual flexibility of the lower jaw.
- Difficulty raising the body off the ground.
- Decreased appetite.
What metabolic disorders cause osteoporosis?
Metabolic bone disease can be caused by a number of factors including vitamin D deficiency, hereditary hypophosphatemia, and hyperparathyroidism (over-activation of the parathyroid gland). The most common form of metabolic bone disorder is osteoporosis.
How is osteoporosis a metabolic disease?
Osteoporosis is a metabolic bone disorder in which bone tissue breaks down, causing low bone density. This makes the bone increasingly fragile and prone to fractures. Osteoporosis is a “silent disease,” since there are no warning signs or symptoms until bone fractures occur.
What is osteogenesis imperfecta caused by?
Osteogenesis Imperfecta types I through IV are caused by mutations in the COL1A1 or COL1A2 genes. These genes carry instructions for the production of type 1 collagen. Collagen is the major protein of bone and connective tissue including the skin, tendons and sclera.
Is a chronic metabolic bone disease that affects bone formation?
Osteoporosis, the most common metabolic bone disease, affects 200 million persons worldwide. Approximately 28 million Americans have osteoporosis or are at risk for it.
Does bone density affect BMI?
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
How does osteopetrosis affect the body?
Osteopetrosis is characterized by overly dense bones throughout the body. Symptoms include fractures, low blood cell production, and loss of cranial nerve function causing blindness, deafness, and/or facial nerve paralysis. Affected individuals may experience frequent infections of teeth and the bone in the jaw.
What type of disease is osteopetrosis?
Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked.
How is metabolic bone disease diagnosed?
The diagnosis of MBD is usually made based upon a careful history, physical examination, radiographic (X-rays) examinations, appropriate lab tests, and bone biopsy if indicated.
Is osteopetrosis a metabolic bone disease?
The name osteopetrosis encompasses a group of hereditary metabolic bone diseases, all of which detrimentally affect bone growth and remodeling leading to generalized osteosclerosis and the potential of pathologic fractures, pancytopenia, and even cranial neuropathies and hepatosplenomegaly in severe cases.
What metabolic disorders are associated with the development of osteoarthritis?
Hypertension (75%), abdominal obesity (63%), hyperglycemia (30%), elevated triglyceride (47%) and low HDL (44%)11 were the major metabolic syndromes associated with it.
