The immune system is a defense mechanism that prevents us from dangerous mediums such as viruses, bacteria, and other microorganisms from entering our bodies. Our immune system usually gets triggered when it detects a foreign cell entering our body. On the other hand, It is also possible that sometimes our immune system can attack our own harmless healthy cells by mistaking them for foreign cells, this condition is called an autoimmune response. An immunologist is a medical practitioner who specializes in treating immune-related disorders. Also known as allergists, these medical doctors are specialized in treating and preventing common conditions such as food allergies and seasonal allergies caused by pollen or dust particles, pet hair, or food like peanuts, seafood, etc.
It is not easy to diagnose the immune system condition due to the homogeneous nature of symptoms. For instance, both pairs of conditions that are allergy and autoimmune disorder can result in common symptoms such as rashes, fatigue, and digestive issues. You could have lupus, multiple sclerosis, rheumatoid arthritis, and/or psoriasis, among a hundred other autoimmune illnesses. It’s crucial to visit a doctor in order to receive the correct diagnosis and begin therapy. So, in this blog, we are gonna talk about Sydney’s top immunologists. If you think you or your family member is suffering from any of the above-mentioned symptoms, we have listed below some top-notch immunologists to make it easily accessible to you.
