Immune System Disorders

Overview

The immune system fights bacteria, viruses, fungi and toxins. It involves various cells, tissues and organs. These include white blood cells, antibodies and the lymphatic system. The immune system recognises and eliminates threats in basic immunology. Immune system disorders occur when the immune system malfunctions. It may be overactive or underactive. Other disorders cause the body to attack its own tissues. Others make it unable to fight infections. Knowing about the normal and abnormal functions of the immune system can detect health risks. These may affect people of all ages. Early treatment can ease symptoms and complications. Lymphatic system and immune system disorders often go hand in hand.

Immune System Disorders Types, Symptoms & Treatment

What are immune system disorders?

Immune system disorders interfere with the normal workings of the immune system. It may not respond to threats. It may also attack the body. The immune system comprises the spleen, thymus, bone marrow and the lymph nodes. This forms the lymphatic and immune system disorders network. When these organs fail, the immune system is compromised. There are different immune disorders. Some are inherited. But some occur later in life due to infections, medications or other illnesses.

Types of Immune System Disorders

Autoimmune Immune System Disorders 

Autoimmune disorders occur when the immune system is overactive. The immune system attacks the body’s own cells. They include lupus, rheumatoid arthritis and type 1 diabetes.

Immunodeficiency Immune System Disorders 

These disorders weaken the immune response. The body has recurrent infections. Primary immunodeficiency is genetic. Secondary immunodeficiency develops later.

Allergic Immune System Disorders 

The immune system overreacts to foreign substances. These substances are called allergens. Allergic reactions are caused by food, dust and pollen.

Inflammatory Immune System Disorders 

The immune system causes inflammation. This damages tissues over time. This includes inflammatory bowel disease.

Immune System Disorders Symptoms

The symptoms vary according to the type of disorder. Some are mild. Others may become severe.

Common symptoms include: 

  • Frequent infections 
  • Slow wound healing 
  • Fever without cause 
  • Constant tiredness 
  • Joint pain 
  • Skin rashes 
  • Swollen lymph nodes 
  • Digestive problems 
  • Breathing issues 
  • Weight loss 

Weak immune systems are prone to infections. Autoimmune diseases can be painful and inflamed. These may affect the skin, lungs, gut or joints.

Immune System Disorders: Types, Symptoms & Treatment

Causes and risk factors of Immune system disorders

 Immune system disorders have many causes. Immune System Disorders Caused by genetics. Some can be passed from parents to their children. These cause problems with immune cells from the beginning of life. These include severe combined immune deficiency (SCID) and IgA deficiency. 

Infections and Immune System Disorders 

Viruses such as HIV compromise the immune system. They kill off key white blood cells. This raises infection risks. 

Medicines and Immune System Disorders 

Chemotherapy and steroids can suppress immunity. Prolonged use raises the risk. 

Lifestyle Risks for Immune System Disorders 

Lack of sleep, stress, smoking and unhealthy diet impact the immune system. Obesity also increases inflammation.

Environmental Causes of Immune System Disorders 

Chemicals or pollution exposure can lead to immune system dysfunction.

Tests for Immune System Disorders

There are a variety of tests to diagnose immune issues. 

Blood Tests for Immune System Disorders 

Blood tests measure white blood cell number and antibodies. These tests can tell how strong the immune system is. 

Antibody Testing in Immune System Disorders 

They can measure the immune response to vaccines. Poor responses can indicate immune system problems. 

Allergy Testing for Immune System Disorders 

Skin prick tests help identify allergens. Allergy blood tests can also be done. 

Tests to Identify Immune Disorders 

These tests detect immune problems due to genetics. This is common in children. 

Imaging Tests for Immune System Disorders 

X-rays or CT scans may show infections or damage to organs. 

Immune System Disorders ICD 10 Code 

ICD-10 codes classify diseases. The following are some common immune system codes:

● Condition ICD 10 Code 

  • Immunodeficiency D84.9 
  • HIV Disease: B20 
  • Lupus M32 
  • Rheumatoid Arthritis M06.9 
  • Food Allergy Z91.01 

These codes help diagnose and treat.

Immune System Disorders: Types, Symptoms & Treatment

Immune System Disorders Treatment

Treatment depends on the cause. Drugs for Immune System Disorders Your doctor may give you steroids or immune suppressants. These reduce inflammation.

Immunoglobulin Therapy for Immune System Disorders 

IVIG is used to increase antibodies in immunodeficient patients. It improves immune defence. 

Antibiotics for Immune System Disorders 

Antibiotics can be used for frequent infections. This helps control bacterial infections. 

Immune System: Allergy Treatment 

Antihistamines reduce allergy symptoms; epinephrine can be used for severe allergies. Bone marrow transplant to treat immune disorders This can be used to treat genetic immune disorders. It replaces damaged immune cells. 

Living With Immune System Disorders 

Long-term treatment is required for immune system disorders. Regular doctor visits are important. Symptoms should be monitored closely. Healthy habits improve immune health. Tips for Living With Immune System Disorders 

  • Eat healthy foods 
  • Sleep well 
  • Stay active 
  • Reduce stress 
  • Avoid smoking 
  • Stay hydrated 
  • Get vaccinations 

When we have lowered immunity, we should avoid infections. Hand hygiene is very important. 

Complications of Immune System Disorders Immune system disorders can lead to complications: 

  • Severe Infections 
  • Organ Damage 
  • Chronic Inflammation 
  • Increased Cancer Risk

FAQS

What are immune system disorders?

Immune system disorders are caused when the immune system is not functioning normally. It could be weak or it could attack the body’s own tissues. They impact the body’s response to disease.

They are caused by genetic, infectious, medicinal and environmental causes. Immune system disorders can be present at birth. Others acquire them during childhood.

Immune disorders can often be well treated. This relieves symptoms and stops complications. Some genetic conditions may require specialised treatment.

Vitamin-rich foods are good. Vegetables, fruit, nuts and protein help immunity. And water is critical.

Yes. Food allergies are caused by an overreaction of the immune system to proteins in food. They are an immune system disease.
