The importance of the immune system in the body is not known properly to many of us, and we have a tendency to take it for granted. The immune system fights infections that enter our body, and is our line of defense against various ailments and diseases. A compromised immune system is unable to combat illnesses with the same efficiency, and as a result, a person suffering from this condition is susceptible to a wide variety of illnesses, and falls sick very often.
Immunodeficiency can be acquired from many different sources. People suffering from impaired immune function have to suffer a lot of difficulties in their lives. Being constantly sick and unwell can only be a bad thing, and the body starts to slowly lose its strength and vitality as well. This is not a rare condition, and many people are found to be affected by it.
