Summary
Fasting is not always necessary for lipid profiles in type-2 diabetes patients. Non-fasting lipid tests show negligible differences, offering a more convenient and biologically relevant assessment for diabetic dyslipidemia management.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Cardiovascular Health
Background:
- Diabetic dyslipidemia, characterized by altered glucose-insulin balance and lipid levels, accelerates atherosclerosis in diabetes mellitus.
- Current guidelines often recommend fasting serum lipid tests for consistency, despite challenges for diabetic patients.
- Fasting requirements can lead to hypoglycemia, reduced test adherence, and logistical strain.
Purpose of the Study:
- To evaluate the clinical significance of fasting versus non-fasting lipid profiles in type-2 diabetes mellitus patients.
- To determine if non-fasting lipid measurements provide comparable diagnostic information to fasting tests.
- To assess the convenience and biological relevance of non-fasting lipid profiles in managing diabetic dyslipidemia.
Main Methods:
- 100 type-2 diabetes mellitus patients were selected after obtaining informed consent.
- Lipid profiles were assessed after an 8-hour fast and 2 hours after a major meal.
- Exclusion criteria included type 1 diabetes, pregnancy, kidney/liver disease, and specific medications.
Main Results:
- Prevalence of dyslipidemia: elevated triglycerides (63%), reduced HDL (96%).
- No statistically significant differences were observed in mean Total Cholesterol, Triglycerides, LDL, HDL, or VLDL between fasting and postprandial states.
- Mean total cholesterol was 170.78±37.90 (fasting) vs. 168.32±31.79 (postprandial).
- Mean triglycerides were 181.24±70.89 (fasting) vs. 184.12±70.24 (postprandial).
Conclusions:
- Fasting and postprandial lipid profiles show negligible differences in type-2 diabetes patients.
- Non-fasting lipid profiles are more convenient and reflect the patient's typical biological state.
- Revisiting the necessity of fasting for lipid profiles in diabetic dyslipidemia management is warranted.

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...

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...

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...

Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.

Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

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.

01:16Insulin: Dosing Regimen and Adverse Effects

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...
