Autoimmune diseases are a group of disorders that occur when the immune system attacks the body’s own cells and tissues.

Basically, the immune system gets confused and begins to attack healthy cells instead of fighting off foreign invaders like bacteria and viruses.

Autoimmune diseases are becoming more common, affecting millions of people worldwide. And while they are not contagious, they can be debilitating and even life-threatening if left untreated.

Common Autoimmune Diseases

There are many different types of autoimmune diseases, and they can affect any part of the body. Here are some of the most common autoimmune diseases:.

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic inflammatory disorder that affects the joints. It can cause pain, swelling, stiffness, and loss of function in the affected joints. Other symptoms may include fatigue, fever, and weight loss.

Lupus

Lupus is a chronic autoimmune disease that can affect many different parts of the body, including the skin, joints, kidneys, and brain. Symptoms can vary widely, but can include fatigue, joint pain, skin rashes, and fever.

Celiac Disease

Celiac disease is an autoimmune disorder that is triggered by the consumption of gluten, a protein found in wheat, barley, and rye. Symptoms can include abdominal pain, diarrhea, and weight loss. The only treatment is a strict gluten-free diet.

Pernicious Anemia

Pernicious anemia is a type of anemia that occurs when the body can’t absorb enough vitamin B12.

This can happen when the immune system attacks the cells in the stomach that produce a protein called intrinsic factor, which is needed for the absorption of vitamin B12. Symptoms can include fatigue, weakness, and difficulty concentrating.

Psoriasis

Psoriasis is a chronic autoimmune disease that affects the skin. It can cause red, scaly patches that are often itchy and painful. Other symptoms can include joint pain and inflammation.

Red Flags to Watch Out for

Autoimmune diseases can be difficult to diagnose because the symptoms can be vague and vary widely from person to person. However, there are some common red flags that you should watch out for:.

Unexplained Fatigue

One of the most common symptoms of autoimmune disease is fatigue. If you find yourself feeling tired all the time, even after getting a good night’s sleep, it could be a sign that something is wrong.

Fatigue can be a symptom of many different autoimmune diseases, so it’s important to get checked out by a doctor if you’re experiencing unexplained fatigue.

Joint Pain and Stiffness

Joint pain and stiffness can be a sign of many different conditions, including autoimmune diseases.

If you’re experiencing persistent joint pain, especially in the morning, it could be a sign of rheumatoid arthritis or another autoimmune disorder.

Skin Rashes

Many autoimmune diseases can cause skin rashes, especially on the face or other exposed areas of the body.

If you’re experiencing a rash that won’t go away, especially if it’s accompanied by other symptoms like joint pain or fatigue, you should see a doctor.

Unexplained Weight Loss

Unexplained weight loss can be a sign of many different conditions, including autoimmune diseases.

If you’re losing weight without trying, or if you’ve lost a significant amount of weight in a short period of time, it’s important to see a doctor.

Digestive Issues

Autoimmune diseases can affect the digestive system, causing problems like abdominal pain, diarrhea, and nausea.

If you’re experiencing persistent digestive issues, especially if they’re accompanied by other symptoms like joint pain or fatigue, you should see a doctor.

Other Red Flags

Other red flags that could indicate an autoimmune disease include:.

Hair loss
Difficulty concentrating or thinking clearly
Changes in mood or behavior
Swollen glands
Fever

If you’re experiencing any of these symptoms, especially if they’ve been going on for a while or are getting worse, you should see a doctor.

Conclusion

Autoimmune diseases can be difficult to diagnose, but there are some common red flags that you should watch out for. If you’re experiencing unexplained fatigue, joint pain, skin rashes, or other symptoms, you should see a doctor.

With early detection and treatment, many autoimmune diseases can be managed and patients can live full and healthy lives.
