We are constantly surrounded by a multitude of viruses, bacteria, microbes, parasites, and toxins that pose a potential threat to our health.
Immune system enables the body to fight against these factors and helps in maintaining good health. Hence health of an individual depends upon the efficiency of immune system.
Since the immune system is a complex network of cells, proteins, tissues, and organs that work together to fight off harmful substances and disease-causing microorganisms called pathogens, absence or abnormality or dysfunction of any segment of immune system can lead to immune deficiency.
Immune deficiency typically leads to frequent infections and some times it may lead to additional medical problems, including cancers.
Patients suffering from immune deficiencies often experience a variety of skin, respiratory, and bone problems as well, and they are more likely to have autoimmune diseases.
