What impact does untreated pain have on the immune system?

Untreated pain is known to have a significant negative impact on the immune system by suppressing its response. Chronic pain or persistent acute pain can lead to physiological changes in the body that adversely affect the immune system's ability to function effectively. When an individual experiences pain, particularly on a long-term basis, stress hormones such as cortisol can be released, which can inhibit the function of immune cells. This suppression can make the body more susceptible to infections and can hinder the healing process by reducing the overall immune defense mechanisms.

This effect is particularly important to recognize in veterinary medicine, where managing pain in animals is crucial not just for comfort but also for ensuring their immune systems remain robust and responsive. Adequate pain management can help mitigate the stress response and promote a healthier immune environment, allowing for better recovery and overall health maintenance in patients.
