Leptin

IntroLab in Belgrade offers testing for leptin, a key hormone for regulating appetite and metabolism. This test provides valuable information about hormone levels in the body and their connection to health conditions such as obesity, diabetes, and metabolic syndrome.

What is leptin?

Leptin, also known as the satiety hormone, plays an important role in the body’s energy metabolism. Its primary function is to suppress appetite, which indirectly helps in weight reduction. It is mainly produced in adipose tissue, but it can also be synthesized in other parts of the body, such as the heart, placenta, breast epithelium, and stomach. Higher concentrations of this hormone are typically found in individuals with a high body mass index and greater amounts of adipose tissue.

Functionality of Leptin

Leptin plays a key role in controlling energy intake and expenditure. It is primarily produced in adipose tissue, from where it is released, travels through the blood-brain barrier, and reaches its receptors located in the hypothalamus. The hypothalamus, our neural command center, uses these signals to regulate appetite and maintain optimal body weight.

Biochemical Processes

This hormone has a significant role in various biochemical processes in our body. Here are a few key processes influenced by leptin:

• Reproductive processes
• Immune responses
• Hematopoiesis (blood production)
• Angiogenesis (formation of new blood vessels)
• Wound healing
• Bone formation and regeneration

Additionally, leptin enhances tissue responsiveness to insulin, enabling more efficient use of glucose within the body.

When is a Leptin Test Conducted?

Testing for leptin is crucial for assessing the health status of individuals with excess weight. It is recommended for children with a hereditary predisposition to obesity and adults experiencing symptoms of prolonged hunger. The goal of the test is to determine deficiency or resistance to this hormone, as well as to identify possible disorders. Sometimes, this test is combined with other tests such as lipid profile, thyroid hormones, glucose, insulin, and hemoglobin A1C for a comprehensive assessment of the health status of obese individuals.
