What is Autoimmune Disease?

Autoimmune disease is a broad term used to describe a number of different medical conditions in which the body’s immune system attacks healthy cells, tissues, and organs. While there are many different types of autoimmune diseases, they all share one common symptom: inflammation. Inflammation is the body’s natural response to injury or infection and is characterized by redness, swelling, pain, and heat. Autoimmune diseases can affect any part of the body, including the skin, joints, muscles, nervous system, heart, lungs, blood vessels, and gut.

What is an autoimmune disease?

An autoimmune disease is a condition in which your body attacks itself. Autoimmune diseases can affect many different parts of the body, including the skin, joints, blood vessels, and organs.

They are caused by a combination of genetic and environmental factors. Some people are born with a predisposition to develop an autoimmune disease, which means that their bodies are more likely to develop one if they are exposed to certain triggers. These triggers can include infections, stress, or certain medications.

Why does the immune system attack the body?

There are a number of reasons why the immune system might attack the body. In some cases, it may be due to a mistake in the immune system itself or it may be because of a viral or bacterial infection. In still other cases, it may be due to something else entirely, such as cancer.

The different types of autoimmune diseases

There are many different types of autoimmune diseases, each with its own set of symptoms and treatment options. Some common types of autoimmune diseases include:

  • Rheumatoid arthritis: a chronic inflammatory disorder that affects the joints and connective tissues
  • Crohn’s disease: a chronic inflammatory disorder that affects the gastrointestinal tract
  • Type 1 diabetes: an autoimmune disorder that results in the destruction of insulin-producing cells in the pancreas
  • Multiple sclerosis: a degenerative neurological disorder that affects the central nervous system
  • Graves’ disease – a disorder that results in the overproduction of thyroid hormone
  • Hashimoto’s disease – a condition that leads to inflammation of the thyroid gland
  • Lupus – a systemic autoimmune disease that can affect any part of the body, but most commonly targets the skin, joints, kidneys, and brain
  • Celiac disease – a gluten-sensitive enteropathy that damages the lining of the small intestine


There is no one answer to this question as the cause is not yet fully understood. However, it is thought that a combination of genetic and environmental factors may play a role in its development. Additionally, some seem to run in families, which suggests that there may be a genetic component to their development.

It can develop when the body’s immune system becomes confused and begins attacking healthy cells instead of foreign invaders like viruses or bacteria. This can happen for a variety of reasons, including exposure to certain environmental triggers (such as certain infections or toxins), stress, or even hormonal changes. Once the body starts attacking healthy cells, it can be very difficult to stop, and this can lead to chronic inflammation and tissue damage.


There are many different types of autoimmune diseases, each with its own set of symptoms. Some common symptoms include fatigue, joint pain, muscle aches, rashes, and fever. Many autoimmune diseases also cause problems with the digestive system, such as nausea, vomiting, and diarrhea. It can also affect the respiratory system, causing shortness of breath and difficulty breathing.


There is no one-size-fits-all answer to this question, as the treatment of autoimmune disease will vary depending on the specific condition diagnosed. However, common treatment options for autoimmune disease include immunosuppressive medications, biological agents, and in some cases, surgery. Immunosuppressive medications work to suppress the immune system and can be used to treat a variety of autoimmune conditions. Biologic agents are also used to treat autoimmune diseases by targeting specific proteins involved in the immune response. In some cases, surgery may be necessary to remove damaged tissue or organs affected by autoimmune disease.


Autoimmune diseases can be difficult to diagnose because they may not have any specific symptoms, or the symptoms may resemble those of other conditions.

There is no definitive way to prevent autoimmune disease, but there are some general things you can do to reduce your risk. These include:

  • eating a healthy diet
  • maintaining a healthy weight
  • exercising regularly
  • avoiding smoking
  • limiting exposure to environmental toxins and chemicals
  • managing stress levels

Autoimmune Disease Risk Factors

There are a number of different factors that can increase your risk of developing an autoimmune disease. These include:

  1. Genetics: Certain disorders such as lupus and multiple sclerosis (MS) tend to run in families.
  2. Weight: Being overweight or obese raises your risk of developing rheumatoid arthritis or psoriatic arthritis. This could be because more weight puts greater stress on the joints or because fat tissue makes substances that encourage inflammation.
  3. Smoking: Research has linked smoking to a number of autoimmune diseases, including lupus, rheumatoid arthritis, hyperthyroidism, and MS.
  4. Certain medications: Myopathy is a rare autoimmune disease that causes muscle weakness. Before starting or stopping any medications, however, make sure to talk to your doctor.
  5. Family history: If you have a family member with an autoimmune disease, you are more likely to develop one yourself.
  6. Gender: Women are more likely than men to develop an autoimmune disease.
  7. Age: Autoimmune diseases tend to occur more often in people aged 30 and over.
  8. Ethnicity: Certain ethnic groups, such as Native Americans and African Americans, are at higher risk of developing autoimmunity.
  9. Environmental factors: Exposure to certain substances, such as mercury or pesticides, may increase your risk of developing an autoimmune disease.

Tests to Diagnose

The most common test is the antinuclear antibody (ANA) test, which looks for antibodies that attack the body’s own tissues. This test is often used to diagnose lupus.

Other common tests include the erythrocyte sedimentation rate (ESR or sed rate) test, which measures how quickly red blood cells settle in a tube of blood; and the C-reactive protein (CRP) test, which measures levels of inflammation in the body.

More specific tests may also be used to diagnose autoimmune diseases such as rheumatoid arthritis, Crohn’s disease, and celiac disease. These tests may look for specific antibodies associated with each disease or for changes in the affected organs or tissues.

When to see a doctor?

If you are experiencing any of the symptoms mentioned above, it is important to see a doctor as soon as possible. Autoimmune disease is a serious condition that can progress quickly and lead to serious health complications if not treated properly. Early diagnosis and treatment are essential for managing autoimmune disease and preventing further damage to your body.


Autoimmune disease occurs when the body’s immune system attacks healthy cells. There are many different types of autoimmune diseases, and each one affects the body in different ways. Some can be mild, while others can be life-threatening. If you think you may have an autoimmune disease, it is important to see a doctor so that you can get the proper diagnosis and treatment.
