What Are Immunologists?

Have you wondered what immunologists are and do? Immunology involves studying the immune system and its process of protecting the body from various infections and viruses. The immune system provides essential defensive capabilities. An active immune system functions automatically and eliminates any external element that is a threat to the body. If your immune system doesn鈥檛 work properly, you are prone to various diseases. Scientists and immunologists research how our body mechanisms protect us from new diseases and how you can improve your immune system.

What Are Immunologists?

What do Immunologists do?

Immunologists help diagnose and treat allergies and other diseases related to the immune system. When your immune system overreacts or doesn鈥檛 work properly, an immunologist can help you maintain the system.

If you are suffering from allergies, you need to consider visiting and consulting an immunologist. Allergies occur when your immune system reacts to substances that are not harmful, thinking that they鈥檙e a threat.

What is an Immune System

The immune system provides protection from various pathogens and harmful substances that can cause a disease or allergy. Some of the most common pathogens that the immune system provides protection against include viruses and bacteria, which can cause infections. The immune system involves cellular and molecular activities. Your body contains two types of immunity. The first is innate immunity, which is the first line of defense, and adaptive immunity, which is the second line of defense.

Conditions that Immunologist can Treat

Below, you will find some conditions related to the immune system that Immunologist can treat:

1.聽聽聽 Allergic Rhinitis

In this condition, you may experience an allergic reaction affecting your airways and nose. Allergic Rhinitis will cause inflammation to the regions of your body that are part of the breathing process. Another name for this condition is hay fever, which is a common condition. The symptoms of this condition also include sneezing, itchy or stuffy nose, etc. This occurs when your body overreacts to an allergen.

2.聽聽聽 Allergic Conjunctivitis

When you are in contact with allergens in this condition, you will experience inflammation around your eyes. You will feel itching, redness, tearing, and swelling of the eyes. Another name for the condition is a pink eye, and it is the result of a bacteria or a virus.

3.聽聽聽 Asthma

Asthma is a chronic condition and can be fatal. In this condition, you may find it difficult to breathe. In this condition, your airway swells and produces excessive amounts of mucus.

4.聽聽聽 Anaphylaxis

This is another condition related to a breathing disorder. This condition is also fatal, and other symptoms include vomiting and low blood pressure. Stings from various insects, foods, latex, and medications can cause Anaphylaxis. Many people are also allergic to peanut butter and berries. After encountering these allergens, your immune system will release large amounts of chemicals that lead to a shock. To minimize the symptoms, doctors prescribe Injectable epinephrine to people with allergies. Whenever they encounter the allergen, they use the epi-pen to avoid symptoms.

5.聽聽聽 Atopic Dermatitis

With this allergic reaction, you may experience itchy and red skin with rashes. Sometimes, this condition can lead to hay fever or asthma. Moreover, medical professionals and researchers have yet to develop a cure for this condition. This eczema-type condition usually affects children, and its triggers include food and environmental conditions. This is a chronic condition, and the reaction can grow worse over time. Other symptoms of atopic dermatitis are sweating, a rise in body temperature, stress, and irritation. Various treatments and avoiding allergic substances can lower the risk of developing such a condition.

6.聽聽聽 Urticaria

People also know this allergic condition as hives. This occurs when your body comes into contact with medication or food allergens. Your skin will turn red and itchy. You may also develop welts through various environmental allergens. Chronic urticarial will remain for around six weeks.

7.聽聽聽 Eosinophilic Esophagitis

This is a chronic disorder of the immune system. In this condition, white blood cells build up in your food pipe or esophagus, causing tissue damage and chronic inflammation.

Immunotherapy treatment adopts various techniques like genetic engineering and gene therapies. Medical professionals can combine this technique with surgery, radiation, chemotherapy, or targeted therapies to improve their results. A patient鈥檚 body undergoes different situations during immunotherapy. Immunotherapy works in the following ways.

  • This therapy educates the immune system to recognize and kill cancer cells

The immune system helps your body protect you from bacteria, viruses, and parasites. Harmful and harmless bacteria are always present in and around your body. White cells protect you from harmful bacteria. Your body organs release聽lymphocytes. Lymphocytes or white cells are of two types. B type cells release antibodies when your body detects disease, and T-cells are responsible for destroying foreign or abnormal cells. If your body prevents you from fighting these infections and diseases, you have a disorder, namely immunodeficiency. Lack of protein causes a weak immune system.

Types of Immunodeficiency Disorder

There are two types of immunodeficiency disorders: primary and secondary immunodeficiency disorder. Both types are mentioned below with further subcategories:

1.聽聽聽聽 Primary Immunodeficiency Disorder

Primary Immunodeficiency disorder or PIDDs are genetically transferred disease. There are more than 200 different types of PIDD disorders. If you are suffering from PIDD, different types of white cells or proteins are missing in your blood, and this leads to severe infections. This deficiency may attack the respiratory system, brain, spinal cord, and urinary or gastrointestinal tracts. Some PIDD diseases affect body organs, cells, and tissues. If you find these symptoms, you might have PIDD:

  • Loss of weight
  • Having problems treating infections
  • Lack of growth
  • Autoimmune disease

a)聽聽聽 X-linked Agammaglobulinemia聽( XLA)

This condition can cause a reduction in B-cells. When B-cells lack in your body, you will be a target of various infections, and the treatment is difficult. Even after you treat these infections, there are chances of getting them again. The most common bacterial infections that you might face are lung infections, ear infections, sinus, and pink eye. If your child is suffering from this immune deficiency, he or she will be fine for 1 to 2 months. He or she gets protection from antibodies that their mother transfers to them while giving birth. Once these antibodies are out of their bodies, they are at risk of infections.

b)聽聽聽 Common Variable Immunodeficiency (CVID)

This disease can cause permanent damage to the respiratory tract because of severe and repeated infections. This deficiency occurs when the body opens to bacteria and viruses and is unable to defend itself. The infections affect the ears and the respiratory tract. In many cases of CVID, diagnosis is not possible at an early stage. If you are suffering from CVID, you might have higher risks of getting cancer. This disease can affect both males and females, and severity may vary from one victim to another.

2.聽聽聽聽 Secondary Immunodeficiency Disorder

Diseases that come under secondary immunodeficiency disorders are a result of environmental factors. Examples include HIV, malnutrition, and severe burns. These are more common than PIDD. If your immune system is infected by external factors like drugs, metabolic diseases, or environmental conditions, this may cause a deficiency in your body. If your body has limited access to food, you might end up suffering from malnutrition, which can result in decreasing the production of T-cells. Your body is prone to various infections if you lack T-cells, as these cells help protect your body from abnormal cells.

a)聽聽聽 AIDS

Human Immunodeficiency Virus or HIV is a type of virus that causes AIDS. Your immune system is a defense mechanism for your body. The healthy immune system can control many viruses with the help of T-Cells. HIV targets these cells and causes them to make copies of viruses that damage your immune system. The advanced stage of HIV disease is AIDS. It is a deadly disease that occurs when HIV is not controlled, and the body loses too many T-Cells. That makes your body’s immune system weak, and you are unable to fight infections.

b)聽聽聽 Leukemia

When cancer infects the tissues that form blood, the result is Leukemia. This type of cancer occurs in both children and adults. This affects your bone marrow and the lymphatic system.


Immunodeficiency is a severe condition, and you should take it seriously. Any ignorance in its treatment can cause serious problems. Some of these diseases can be fatal. For a consultation regarding this deficiency, you can contact us.
