What is the Immune System?
A strong immune system is associated with robust health. It is your body’s defense system fighting against outside invaders to maintain your health and longevity.
Your immune system consists of barriers, cells, tissues, and organs located throughout your entire body. This powerful system protects you against potential microbial invaders like bacteria, viruses, fungi, and parasites, in addition to detecting and destroying cancer and damaged cells.
How Does Your Immune System Function?
The immune system is divided into two basic subsystems. Your innate immunity gets its name because you are born with it. It provides protection by recognizing infectious invaders like bacteria and viruses. Barriers like the skin, mucus, and cell walls block invading organisms, while specialized cells termed neutrophils and macrophages engulf the microbes to diminish any infection. Other immune soldiers called natural killer cells destroy infected cells infiltrated by bacteria and viruses. Finally, on the innate side, dendritic cells present damaged tissue and fragments of microbes to T-cells.
T-cells are part of the adaptive immune system. They are responsible for killing infected cells and secreting cytokines, which induce more inflammation. The adaptive immune division starts it’s work usually five days or longer after an initial infection. B-cells which are derived from bone marrow function by producing antibodies. Once antibodies are created to antigens, they are categorized for future response to infections.
The lymphatic system is composed of lymph nodes, lymph vessels, tonsils, thymus, and bone marrow, creating a network of organs and tissues whose priority function is the transportation of lymph fluid. This fluid is carried throughout the body, and it carries bacteria, viruses, and damaged cells to lymph nodes which filter out debris.
Even though the immune system is located around the entire body, approximately 80% of it is centered in your digestive system. The reason for this is simple; your gut is where the outside world intersects with the inside of the body. The immune system in your digestive system must vet out every bite of food and fluid that you take in daily so that viruses, bacteria, fungi, and bacteria do not pass into your bloodstream. The immune system in the gut sees more activity daily than the rest of the body does in a lifetime.
Now you can understand why it is so important to keep a healthy working digestive system. Symptoms such as bloating, gas, indigestion, constipation, and diarrhea all need to be resolved to eliminate gut inflammation, preserve a healthy gut microbiota, and maintain a strong immune system.
How To Know If Your Immune System is Performing Well?
Laboratory tests can determine if white blood cells, basophils, and eosinophils are out of range. Tests may be used to look for specific antibodies, or an easy self-assessment test may be utilized. You can evaluate your immune system by answering these seven easy questions:
- What is your stress level like?
- Do you get frequent colds and cases of flu?
- Do your wounds heal slowly?
- Do you suffer from frequent infections?
- Are you tired much of the time?
- Do you have digestive disturbances?
- What is the quality of your sleep?
Stress increases cortisol levels in the body. It lowers white blood cell counts and increases inflammation throughout the entire body. Studies show that high stress is directly related to a lower state of immune function.
Experiencing frequent colds is an example of the body’s innate and adaptive immune systems not being able to catch up. Individuals with low immune status require added support.
Slow-healing wounds show inefficiency in your immune system’s ability to destroy invading microbes and eliminate damaged tissue. This is another sign that your immune system requires bolstering.
There are several reasons why you may experience exhaustion. Many of us do not receive sufficient sleep. Studies indicate a direct correlation between a lack of sleep and a decline in leukocytes and natural killer cells, both necessary to maintain healthy immunity.
Inflammation in the digestive tract may occur from a diet deficient in nutrients and high in pharmaceuticals, toxic substances, and abundant in stress. An inflammatory gut leads to a decrease in the mucosal border, lower amounts of secretory IgA, a dysbiosis, and a leaky gut. This means a lowered immune function and an increased potential for systemic infection as well as autoimmune spectrum disorders.
What Are the Most Common Symptoms of a Low Immune System?
- Frequent infections, especially respiratory, sinus, ear, and skin.
- Inflammation of internal organs
- Digestive issues such as pain, diarrhea, constipation, nausea or vomiting
- Anemia and low platelet counts
- Delayed growth and maturation
What Can Conventional Medicine Treatment Do to Modulate the Immune System?
Conventional medicine primarily relies on a pharmaceutical approach to alter any immune response. It’s usually a one size fits all approach. Either immune suppressants or immune stimulants may be prescribed.
When it comes to immunodeficiency, immunoglobulin therapy may be selected. It can either be injected or administered through an intravenous line. It contains antibodies necessary to support immune function.
Interferon-gamma therapy is often the drug of choice. This substance is naturally synthesized in the body; it combats viruses and bacteria through its support of the immune system. Immuno-suppressant medications may be given to assist the body, usually in organ transplant acceptance.
