Summary
Vitamin D may prevent type 1 and type 2 diabetes. Recent studies suggest vitamin D or active vitamin D administration effectively prevents diabetes incidence, impacting extraskeletal health.
Area of Science:
- Endocrinology
- Metabolic Diseases
- Nutritional Science
Background:
- Vitamin D is crucial for calcium and bone metabolism.
- Emerging evidence suggests extraskeletal effects of vitamin D.
- Vitamin D deficiency is linked to increased incidence of type 1 and type 2 diabetes.
Purpose of the Study:
- To evaluate the role of vitamin D in diabetes mellitus incidence.
- To assess the effectiveness of vitamin D supplementation in preventing diabetes onset.
- To resolve inconsistencies in previous research regarding vitamin D and diabetes.
Main Methods:
- Review of observational studies.
- Analysis of randomized controlled trials (RCTs).
- Synthesis of meta-analyses findings.
Main Results:
- Observational studies consistently associate vitamin D deficiency with higher diabetes incidence.
- RCT results on preventing type 2 diabetes have been inconsistent.
- Recent comprehensive analyses confirm vitamin D's efficacy in preventing both type 1 and type 2 diabetes.
Conclusions:
- Vitamin D administration is effective in preventing type 1 and type 2 diabetes.
- Vitamin D plays a significant role in metabolic health beyond bone health.
- Further research and clinical application of vitamin D for diabetes prevention are warranted.

2.3K
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...

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...

01:15Diabetes: Management and Pharmacotherapy
268
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

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...

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

01:16Insulin: Dosing Regimen and Adverse Effects
168
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
