Summary
Type 2 diabetes patients show reduced bone mineral density (BMD) at the distal radius, indicating selective cortical bone loss. Good glycemic control is vital for preventing bone loss in these individuals.
Area of Science:
- Endocrinology
- Orthopedics
- Metabolic Diseases
Background:
- Type 2 diabetes is a complex metabolic disorder.
- Bone health is a growing concern in diabetic populations.
- Previous research suggests a link between diabetes and altered bone metabolism.
Purpose of the Study:
- To investigate bone mineral density (BMD) differences in type 2 diabetes patients compared to controls.
- To explore the relationship between glycemic control and BMD at various skeletal sites.
- To identify potential sites for assessing bone loss in type 2 diabetes.
Main Methods:
- Bone mineral density (BMD) was measured at the lumbar spine, femoral neck, and distal radius.
- A cohort of 145 type 2 diabetes patients and 95 non-diabetic controls participated.
- HbA1c levels over the preceding 2 years were analyzed in relation to BMD.
Main Results:
- Type 2 diabetes patients exhibited significantly lower BMD and Z scores at the distal radius.
- A significant negative correlation was observed between distal radius BMD and mean HbA1c in diabetic patients.
- These findings suggest selective cortical bone loss in type 2 diabetes.
Conclusions:
- Type 2 diabetes is associated with selective cortical bone loss, particularly at the distal radius.
- Monitoring BMD at the radius may be important for diabetic patients.
- Maintaining optimal glycemic control is crucial for mitigating bone loss in type 2 diabetes.

Diabetes Mellitus: Type 2 and Gestational
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...
Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
Carbohydrate Metabolism
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 the...

Hypoglycemia
Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
