Leptin is a hormone produced by fat cells that signals the brain to regulate appetite and energy expenditure. In healthy individuals, higher body fat produces more leptin, reducing hunger. However, many overweight individuals develop 'leptin resistance,' where the brain no longer responds to high leptin levels. Understanding your leptin level can provide insights into metabolic health and weight management challenges.
Hormone testing measures the chemical messengers that regulate energy, mood, sex drive, weight, and reproduction — helping pinpoint imbalances that cause a wide range of symptoms.
Anyone with unexplained fatigue, mood changes, libido changes, weight changes, irregular cycles, or considering hormone replacement therapy.
