Your body is constantly working behind the scenes to keep everything in balance—especially when it comes to stress. One of the key players in this process is ACTH, or Adrenocorticotropic Hormone. While it may not be a household name, ACTH has a major impact on how your body responds to stress, maintains energy levels, and manages inflammation.Produced by the pituitary gland, a pea-sized organ located at the base of your brain, ACTH stimulates the adrenal glands (located above the kidneys) to release cortisol, your body’s primary stress hormone. Cortisol helps regulate blood pressure, blood sugar levels, immune responses, and your body’s use of fats, proteins, and carbohydrates. Essentially, ACTH is the messenger that tells the adrenal glands to “gear up” whenever your body senses physical or emotional stress.

Why is ACTH Important?

ACTH isn’t just about stress—it’s about survival. Whether you’re facing a tough workout, a sleepless night, or a big emotional event, your adrenal glands rely on ACTH to maintain balance. Too much or too little ACTH can disrupt the delicate hormonal harmony in your body.

Why ACTH Matters More Than You Think: Most people associate stress with emotions—but stress is also a deeply physical process. ACTH helps your body handle everything from a minor cold to a major life crisis. When your ACTH and cortisol levels are in sync, your body operates smoothly. But when something’s off, it can affect your mood, sleep, energy, and even your immune system.Getting tested at the right time can help identify hidden hormone imbalances before they turn into chronic issues. Understanding your ACTH levels is an important step toward balanced health—especially if you're dealing with ongoing fatigue, mood changes, or unexplained symptoms.
