Autoimmune disease facts for kids
Autoimmune disease is when your body's immune system accidentally attacks its own healthy parts. Normally, your immune system is like a superhero team inside you. Its job is to find and fight off bad guys like bacteria and viruses that can make you sick. But sometimes, this system gets confused and starts attacking your own cells, tissues, or organs instead of protecting them. This can cause different health problems.
Here are some examples of autoimmune diseases:
- Crohn's disease
- Graves' disease
- Type 1 diabetes
- Multiple sclerosis
- Juvenile rheumatoid arthritis (also called juvenile idiopathic arthritis)
- Celiac Disease
- Myasthenia gravis

The Body's Defenders: Your Immune System
Your immune system is an amazing network of cells, tissues, and organs that work together to keep you healthy. Think of it as your body's personal army. It has special cells, like white blood cells, that patrol your body. When they find something foreign and harmful, like a germ, they create special proteins called antibodies to fight it off. This helps you recover from illnesses and prevents you from getting sick again.
When the Immune System Gets Confused
In an autoimmune disease, your immune system makes a mistake. It can't tell the difference between healthy body cells and harmful invaders. So, it starts to attack your own healthy tissues. Scientists don't fully understand why this happens. It might be a mix of your genes (things you inherit from your parents) and things in your environment, like certain infections.
When your immune system attacks your own body, it causes inflammation. This is your body's natural response to injury or infection, but when it happens all the time in healthy tissues, it can cause damage and lead to various symptoms.
Different Ways Autoimmune Diseases Affect the Body
There are over 100 different types of autoimmune diseases, and they can affect almost any part of the body. Here are some of the examples mentioned earlier:
- Crohn's disease affects the digestive system, causing inflammation in the gut.
- Graves' disease makes your thyroid gland (a gland in your neck) produce too many hormones.
- Type 1 diabetes happens when the immune system attacks the cells in the pancreas that make insulin, a hormone needed to control blood sugar.
- Multiple sclerosis affects the brain and spinal cord, which are part of your nervous system.
- Juvenile rheumatoid arthritis causes joint pain and swelling, mainly in children and teenagers.
- Celiac Disease is when eating gluten (a protein found in wheat, barley, and rye) causes the immune system to damage the small intestine.
- Myasthenia gravis affects the connection between nerves and muscles, leading to muscle weakness.
What Are the Signs of an Autoimmune Disease?
The symptoms of autoimmune diseases can be very different depending on which part of the body is being attacked. However, some common signs include:
- Fatigue: Feeling very tired, even after resting.
- Pain and swelling: Especially in joints or muscles.
- Skin problems: Rashes or other skin changes.
- Fever: A low-grade fever that comes and goes.
- Digestive issues: Problems like stomach pain or diarrhea.
Because the symptoms can be so varied, it can sometimes take a while for doctors to figure out what's going on.
How Doctors Find and Treat Autoimmune Diseases
If a doctor suspects an autoimmune disease, they will usually do a physical exam and order some blood tests. These tests can look for specific antibodies or signs of inflammation in your body.
There is no cure for most autoimmune diseases, but they can be managed. Treatment often focuses on:
- Reducing inflammation: Medicines can help calm down the immune system's attack.
- Relieving symptoms: Other treatments can help with pain, fatigue, or other specific problems.
- Replacing substances: For example, people with Type 1 diabetes need to take insulin.
Living with an autoimmune disease means working closely with doctors and sometimes making changes to your lifestyle. Many people with these conditions can live full and active lives with the right care.
