Immunoglobulin G

What's 
Total IgG
?
Immunoglobulin G (IgG) is a major type of antibody that makes up around 70-80% of all the antibodies in your blood and body fluids. Created by your immune system, IgG serves as a crucial line of defense, recognizing and neutralizing harmful intruders like bacteria and viruses. Think of it as your body's personal security team, always on the lookout to protect you from infections. What's more, IgG has a special ability to 'remember' past encounters with harmful substances, allowing for a faster and more effective response if the same intruders attack again. This memory feature of IgG is the foundation of long-lasting immunity after vaccinations or recovery from infections.
If Your Levels Are High
Elevated Immunoglobulin G (IgG) levels might mean that your immune system is working extra hard to protect you. This could be due to an ongoing infection, an autoimmune condition like lupus or rheumatoid arthritis, or a chronic inflammatory state where your body is constantly trying to fight off threats. Some medications, such as corticosteroids or immune suppressants, can also cause an increase in IgG levels. Additionally, it's worth noting that some people naturally produce more IgG than others, which isn't always a cause for concern. In any case, higher IgG levels show that your body's defense system is responding to something, like having more security guards on duty. Identifying the reason behind this response is important for addressing the root cause and helping your immune system find balance.
Symptoms of High Levels
Symptoms of high levels of IgG may not be specific and can vary widely, depending on the underlying cause. They could include fatigue, joint pain, or frequent infections. In some cases, there may be no noticeable symptoms at all.
If Your Levels are Low
Having low Immunoglobulin G (IgG) levels might mean that your body isn't making enough of these important antibodies to protect you from infections. This could be due to various reasons, such as being stressed out, not eating well, or not getting enough sleep, which can all affect how well your immune system works. Some medications, like corticosteroids or drugs that suppress the immune system, could also cause lower IgG levels. Furthermore, certain genetic disorders or ongoing infections might be contributing to your low IgG levels. It's essential to have enough IgG since it plays a big role in keeping you healthy and fighting off harmful invaders.
Symptoms of Low Levels
Symptoms of low levels of IgG could include frequent or recurrent infections, prolonged illness recovery times, and general feelings of fatigue or weakness.
