Question 1

What is the Meaning of Ghrelin-Leptin Axis?

Accepted Answer

The Ghrelin-Leptin Axis describes the critical interaction between ghrelin and leptin, two hormones that physiologically regulate hunger, satiety, and overall energy balance. Ghrelin signals hunger and promotes food intake. Leptin conveys energy sufficiency and suppresses appetite. This system is fundamental for stable body weight.

Question 2

What is the Context of Ghrelin-Leptin Axis?

Accepted Answer

This hormonal axis operates primarily within the neuroendocrine system, with central integration in the hypothalamus. Peripheral signals originate from the stomach for ghrelin and from adipose tissue for leptin. Their coordinated action influences neuronal circuits controlling food intake and energy expenditure, forming a vital feedback loop responsive to energy status.

Question 3

What is the Significance of Ghrelin-Leptin Axis?

Accepted Answer

Understanding the Ghrelin-Leptin Axis holds considerable clinical importance for individuals facing body weight regulation challenges, including obesity. Dysregulation can contribute to persistent hunger, impaired satiety, and difficulty achieving a healthy weight. Recognizing these imbalances helps clinicians develop targeted strategies for patient well-being.

Question 4

What is the Mechanism of Ghrelin-Leptin Axis?

Accepted Answer

Ghrelin, secreted pre-prandially, stimulates orexigenic neurons, specifically neuropeptide Y and agouti-related peptide in the hypothalamic arcuate nucleus, promoting food consumption. Conversely, leptin, released proportionally to fat stores, activates anorexigenic pro-opiomelanocortin neurons in the same region, leading to reduced food intake and increased energy use.

Question 5

What is the Application of Ghrelin-Leptin Axis?

Accepted Answer

In clinical practice, insights into the Ghrelin-Leptin Axis inform approaches to weight management. Therapies targeting ghrelin receptors or enhancing leptin sensitivity are under investigation for treating obesity. Lifestyle modifications, like regular physical activity and balanced nutrition, can positively influence these hormonal pathways.

Question 6

What is the Metric of Ghrelin-Leptin Axis?

Accepted Answer

The activity and balance of the Ghrelin-Leptin Axis can be assessed through clinical and biochemical parameters. Serum ghrelin levels, measured by immunoassay, indicate hunger signaling. Serum leptin concentrations reflect adipose tissue mass and satiety signals. These markers, alongside anthropometric measurements, offer insight into energy status.

Question 7

What is the Risk of Ghrelin-Leptin Axis?

Accepted Answer

Imbalances within the Ghrelin-Leptin Axis carry specific health risks. Leptin resistance, where target tissues become less responsive to leptin, can lead to uncontrolled hunger and weight gain. Chronically elevated ghrelin levels, sometimes observed post-bariatric surgery, may also contribute to persistent appetite. Unmanaged dysregulation increases metabolic syndrome susceptibility.
