Summary
Controlled fasts aid in diagnosing paediatric hypoglycaemia but require critical samples for metabolic studies. Always exclude metabolic disorders before fasting to ensure safety and accurate results.
Area of Science:
- Pediatric Endocrinology
- Clinical Diagnostics
- Metabolic Disorders
Background:
- Hypoglycaemia is a critical concern in pediatric clinical practice.
- Accurate diagnosis requires timely collection of specific samples.
- Certain metabolic conditions necessitate exclusion before diagnostic procedures.
Purpose of the Study:
- To evaluate the role of controlled fasting in diagnosing and managing paediatric hypoglycaemia.
- To emphasize the importance of sample collection during hypoglycaemic events.
- To highlight critical pre-fasting assessments and safety protocols.
Main Methods:
- Review of controlled fasting protocols in paediatric settings.
- Emphasis on sample collection during hypoglycaemia for metabolic and endocrine studies.
- Identification of conditions (e.g., fatty acid oxidation defects, hyperinsulinism, adrenal insufficiency) to exclude prior to fasting.
Main Results:
- Controlled fasts are valuable tools when used appropriately.
- Fasting is not a replacement for critical sample collection.
- Safety and efficacy depend on strict adherence to protocols and experienced supervision.
Conclusions:
- Controlled fasts are safe and effective in experienced settings with strict protocols.
- Proper planning, laboratory collaboration, and expert supervision are essential for successful controlled fasting studies.
- Exclusion of specific metabolic and endocrine disorders is a prerequisite for safe and informative controlled fasting.

1.2K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

3.2K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

5.0K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

8.1K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

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...
