Summary
Type 2 diabetes (T2D) in youth increases fracture risk due to compromised bone strength, even with normal bone density. Early intervention is vital for long-term skeletal health in diabetic children and adolescents.
Area of Science:
- Endocrinology and Metabolism
- Orthopedics and Bone Health
- Pediatric Health
Background:
- Type 2 diabetes (T2D) is increasingly diagnosed in youth, posing significant health challenges.
- Skeletal health complications, particularly bone fragility, are emerging concerns in pediatric T2D.
- Understanding the impact of T2D on bone development during critical growth periods is essential.
Purpose of the Study:
- To review the impact of type 2 diabetes (T2D) on skeletal health in the pediatric population.
- To elucidate the physiology and pathophysiology of diabetic bone fragility in youth.
- To highlight recent scientific findings (past five years) regarding T2D and bone health.
Main Methods:
- Review of current literature on T2D and its effects on skeletal health in youth.
- Analysis of findings from preclinical (mouse models) and human studies.
- Inclusion of data from Mendelian randomization studies to explore genetic influences.
Main Results:
- Type 2 diabetes is linked to elevated fracture risk in youth, irrespective of bone mineral density.
- T2D may impair peak bone mass acquisition during adolescence.
- Pathophysiological mechanisms include reduced bone turnover, decreased unmineralized matrix, and increased collagen glycation, leading to weaker bones.
Conclusions:
- Diabetic bone fragility is an underdiagnosed complication in youth with T2D.
- Metabolic disturbances, genetic factors, and cellular dysfunction contribute to compromised bone strength.
- Early intervention is crucial to mitigate long-term skeletal health issues in pediatric T2D patients.

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

3.0K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

4.4K
The most apparent functions of the skeletal system are support, protection, and movement. However, bone tissue also performs several other critical metabolic functions. For one, the bone matrix acts as a reservoir for a number of minerals important to the functioning of the body, especially calcium and phosphorus. These minerals, present in the bone tissue, can be released back into the bloodstream when required. Calcium ions, for example, are essential for muscle contractions and controlling...

01:29Bone Disorders
4.0K
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...
