Autoimmune diseases happen when the body’s defense system attacks itself. Normally, the immune system protects us from germs and infections. But in autoimmune diseases, it mistakes healthy parts as enemies. This causes many problems inside the body.
If you or someone you know feels sick for a long time without a clear reason, it might be an autoimmune disease. Knowing the symptoms can help find help early.

What Are Autoimmune Diseases?
Autoimmune diseases are many. They affect different parts of the body. Some common ones are rheumatoid arthritis, lupus, and type 1 diabetes. Each disease has its own signs, but some symptoms are common.
These diseases can last a long time. Sometimes, symptoms come and go. Doctors call this “flare-ups” and “remission.” It is important to watch symptoms carefully.

Fatigue: More Than Just Tiredness
Fatigue is the most common symptom. It is different from normal tiredness. People with autoimmune disease feel weak all the time. Rest does not always help. This makes daily tasks hard. If you feel this way for many weeks, tell a doctor. Fatigue may be a sign of illness inside the body.
Fever Without Infection
A low fever is common in autoimmune diseases. The body fights its own cells. This can cause a mild fever. It may come and go. If you have fever and no infection, it might be a warning sign.
Swollen Joints and Pain
Many autoimmune diseases attack the joints. This causes pain and swelling. Joints may look red or feel warm. It is hard to move them. Rheumatoid arthritis is an example. Joint pain can affect hands, knees, or feet. It may happen on both sides of the body.

Skin Changes and Rashes
Skin problems are common. Red spots, rashes, or patches can appear. Lupus often causes a butterfly-shaped rash on the face. Other diseases cause dry or itchy skin. If your skin changes without a clear cause, see a doctor.
Muscle Weakness and Pain
Autoimmune diseases can make muscles weak. You might find it hard to lift things or walk. Muscle pain may feel like soreness or cramps. This symptom can make daily life tough.
Hair Loss
Losing hair is another sign. It can happen in patches or all over the head. Some autoimmune diseases attack hair follicles. This causes hair to fall out. Hair loss may return after treatment, but it can take time.
Digestive Issues
Some autoimmune diseases affect the stomach and intestines. Symptoms include pain, diarrhea, or constipation. Sometimes, people feel bloated or sick after eating. Diseases like celiac disease and Crohn’s disease cause these problems.

Numbness and Tingling
Autoimmune diseases can affect nerves. This causes numbness or tingling in hands and feet. Some people feel a “pins and needles” sensation. This can make it hard to hold or walk.
Swollen Glands or Lymph Nodes
The body’s lymph nodes may swell. They are part of the immune system. Swollen glands can feel like small lumps under the skin. This happens because the body is fighting something.
