Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Easy bruising and bleeding
Unexplained bruises, prolonged bleeding from minor cuts, or bleeding gums indicating platelet or coagulation issues.
Seek immediate care if experiencing severe bleeding, blood in urine or stool, or unexplained bruising over large areas.
Fatigue and weakness
(constitutional)Persistent tiredness and lack of energy that interferes with daily activities, often due to impaired immune function.
Frequency: 70-80% of patients
Recurrent infections
(immunologic)Frequent bacterial and viral infections including sinus, respiratory, and ear infections due to inadequate antibody protection.
Frequency: 75-85% of patients
Skin rash
(dermatologic)Redness, itching, or patchy skin changes that may appear intermittently or persistently.
Frequency: 40-50% of patients
Chronic diarrhea
(gastrointestinal)Loose or watery stools lasting more than four weeks, often related to gut immune dysfunction.
Frequency: 30-40% of patients
Joint pain and swelling
(musculoskeletal)Aching, stiffness, or swelling in one or multiple joints, often affecting knees, wrists, and elbows.
Frequency: 25-35% of patients
Peripheral neuropathy
(neurologic)Numbness, tingling, or burning sensations in extremities, typically affecting hands and feet.
Frequency: 10-15% of patients
Swollen lymph nodes
(immunologic)Enlarged lymph nodes, particularly in neck, armpits, or groin, often persistent and sometimes tender.
Frequency: 10-20% of patients
Shortness of breath
(respiratory)Difficulty breathing or feeling winded with minimal exertion, which may indicate lung involvement or anemia.
Frequency: 30-40% of patients

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Infection Surveillance
Regular monitoring for recurrent respiratory and sinus infections associated with IgG deficiency. Maintain detailed infection logs to identify patterns and guide treatment decisions.
Immunoglobulin Replacement Therapy
Intravenous or subcutaneous immunoglobulin infusions to restore protective antibody levels. Dosing and frequency determined by weight, severity, and clinical response.
Additional treatment options
Antibiotic Prophylaxis
Targeted antibiotic therapy to prevent recurrent bacterial infections, particularly during high-risk seasons or for patients with documented sinopulmonary infections.
medicationImmune-Supportive Nutrition
Protein-rich diet with adequate zinc, vitamin D, and selenium to support endogenous antibody production. Supplementation may be considered when dietary intake is insufficient.
dietaryVaccination Review and Administration
Ensure current immunizations including pneumococcal and influenza vaccines to compensate for reduced antibody response. Post-vaccination titers may guide booster timing.
