Interleukin 6

Interleukin 6 is a protein that acts as a signal for inflammation in your body, helping regulate immune responses to infections and injuries.

📋 About This Biomarker

Interleukin 6 is like a messenger in your body that helps coordinate the immune system's response to infections and injuries. Produced by various cells, including immune cells and muscle cells, IL-6 signals when there's a problem, such as an infection or inflammation, prompting the body to take action. Think of it as an alert system that notifies your body's defence forces to spring into action. By measuring IL-6 levels, we can get a snapshot of how your body is responding to stress, infections, or chronic diseases. High levels might indicate that your body is fighting off an invader or dealing with an inflammatory condition. Monitoring IL-6 can provide valuable insights into your overall health and how your body manages inflammation.

🎯 Why We Test This

Testing IL-6 levels can provide important insights into how your body is managing inflammation and stress. It's useful for detecting hidden infections, monitoring chronic inflammatory conditions, and assessing the risk of diseases associated with inflammation, such as heart disease or diabetes. Understanding your IL-6 levels can help you and your healthcare provider make informed decisions about your health, potentially leading to early intervention and better management of any underlying issues.

⚠️ What Affects It

Several factors can influence IL-6 levels in your body. Infections and inflammatory conditions are primary triggers, causing IL-6 levels to rise as your immune system responds. Chronic stress, lack of sleep, and physical inactivity can also elevate IL-6. Lifestyle habits like smoking, excessive alcohol consumption, and poor diet contribute to higher levels. Certain medical conditions, such as autoimmune diseases, obesity, cardiovascular diseases, and some cancers, can affect IL-6 levels. Even factors like ageing and hormonal changes can influence IL-6 production.

📈 How to Improve

If your IL-6 levels are high or approaching high, adopting a healthier lifestyle can help reduce inflammation. This includes eating a balanced diet rich in fruits, vegetables, whole grains, and omega-3 fatty acids, engaging in regular physical activity, getting enough sleep, and managing stress through relaxation techniques like meditation or yoga. Avoiding smoking and limiting alcohol intake are also beneficial. If levels are low or near the lower limit, and if this is associated with health issues like a weakened immune system, working with a healthcare professional to address any underlying conditions is important. They might recommend specific treatments or lifestyle changes to support your immune health. Regular monitoring and following medical advice can help maintain IL-6 levels within a healthy range.

📊 Understanding Your Results (ng/L)

Low
Lower-than-normal IL-6 levels are uncommon and usually not a cause for concern. They might occur in cases where the immune system is suppressed, such as in certain medical treatments or conditions that weaken immune function. If you're experiencing frequent infections or have concerns about your immune health, it's important to discuss these results with a healthcare provider to determine if further evaluation is needed.
Optimal
IL-6 levels within the normal range suggest that there is no significant inflammation or stress affecting your body at this time. This means your immune system is functioning well, and your body is in a state of balance. Maintaining healthy lifestyle habits helps keep IL-6 levels within this range, supporting overall well-being and reducing the risk of chronic diseases associated with inflammation. When IL-6 levels are nearing the upper limit of normal, it may indicate mild inflammation or stress in the body. This could result from factors like recent physical exertion, minor infections, stress, or lack of sleep. While not immediately concerning, it's a signal to pay attention to your health habits. Making positive lifestyle changes, such as improving your diet, increasing physical activity, and managing stress, can help bring levels back into a healthier range. If your IL-6 levels are near the lower end of the normal range, it generally indicates low levels of inflammation, which is a good sign. It suggests that your body is not currently under stress from infections or inflammatory conditions. However, extremely low levels might be observed in individuals with weakened immune systems, potentially indicating an impaired ability to respond to infections. It's important to interpret these results in the context of your overall health and any symptoms you may have.
High (> 7 ng/L)
If your IL-6 levels are higher than normal, it suggests that your body is experiencing significant inflammation or stress. This could be due to acute infections, chronic inflammatory diseases, autoimmune disorders, or other serious conditions like heart disease or certain cancers. High IL-6 levels are like a red flag, indicating that your body is actively fighting something or that there might be an underlying issue causing persistent inflammation. It's important to consult with a healthcare professional to identify the cause and determine the appropriate course of action.
