The Leptin test measures the level of leptin, a hormone produced by fat cells that helps regulate energy balance and body weight. Leptin plays a key role in appetite control and metabolism. Abnormal leptin levels can contribute to obesity, metabolic syndrome, and other health issues. Understanding your leptin levels can help you manage your weight and improve metabolic health. This test is beneficial for individuals looking to understand their appetite regulation and energy balance better.

About This Test

Reason to Check It

"Leptin is an adipokine secreted from adipose tissue. Leptin sends a signal to the hypothalamus in the brain to regulate appetite and energy expenditure. Leptin deficiency results in excessive eating and decreased energy expenditure, leading to obesity. In contrast, elevated levels of leptin can represent leptin resistance, which also paradoxically leads excessive eating and decreased energy expenditure. Elevated levels of leptin have been associated with insulin resistance, metabolic syndrome, obesity, hyperlipidemia, hypertension, diabetes, and may be an independent risk factor for coronary artery disease. Many of these associations are thought to be due to leptin's pro-inflammatory signaling." - Dr. Alan Hopkins
