People who deal with recurring infections suffer from a low, health-related quality of life, as it’s impossible to feel your best when your body is at war with itself. Recurring infections are a sign that something is happening within the body, and it could mean a lack of immunoglobulin G antibodies. Allow us to answer frequently asked questions about immunoglobulin G antibodies and what a deficiency may look like:

What is an IgG deficiency?

An IgG deficiency occurs when the body does not create enough or creates too much Immunoglobulin G, an antibody that is found in blood circulation. This antibody is very important to a person’s health, as it fights off viruses and bacteria that cause infections.

What causes an IgG deficiency?

Researchers are still trying to determine exactly why certain people have trouble producing immunoglobulin G. This deficiency may occur because of genetics, taking certain medication, or having certain health conditions/issues.

What are the symptoms of an IgG deficiency?

The biggest sign of an IgG deficiency is recurring infections, as this shows that the immune system is incapable of producing immunoglobulin G antibodies. Common infections include:

  • Bronchitis
  • Ear infections
  • Gastrointestinal infections
  • Infections that result in a sore throat
  • Pneumonia
  • Sinus infections and other respiratory infections

What treatment options are available?

Fortunately, treatment options are available that have helped minimize (or eliminate) the number of yearly infections! The recommended treatment option is based on the severity of your infections and how often the occur. Your Langford Allergy team member will also consider the health of your immune system and what would be best to help it thrive.

Many people have found relief with medication or IV treatment, like:

  • HYQVIA
  • Hizentra
  • Cutaquig
  • Intravenous Immunoglobulin (IVIG)
  • Subcutaneous Immunoglobulin (SCIG)

How is an IgG deficiency diagnosed?

Because the immunoglobulin G antibody is (or should be) in a person’s blood circulation, your Langford Allergy team member will take a blood sample to measure the amount of immunoglobulin G. A below average amount of immunoglobulin G is an indicator that this health condition may be the culprit to your recurring infections.
