7 Most Common Autoimmune Disorders

Autoimmune disorders are like the ultimate game of “Guess Who?” Your immune system thinks it’s playing a fun game of identifying and eliminating foreign invaders. But instead, it ends up attacking your cells and tissues. As a result, you’re left with chronic inflammation, swelling, and a whole host of annoying and painful symptoms.

But don’t worry; there’s hope! This post will explore the seven most common autoimmune disorders and what you need to know about them. Let’s get started!

What is an Autoimmune Disorder?

Autoimmune disorders are a set of diseases that happen when the immune system, which is supposed to protect the body from different viruses and bacteria, attacks healthy cells and tissues instead. Depending on what part of the body is affected, this can cause various symptoms and health problems.

Why is it so important to know what autoimmune disorders look like? The answer is simple: finding and treating these conditions early can make a huge difference in managing them. In fact, many autoimmune disorders are easier to treat and control when they are caught early.

Now, let’s take a closer look at each of the seven most common autoimmune disorders:

Hashimoto’s Thyroiditis 

Hashimoto’s thyroiditis is a disorder affecting the thyroid gland, a tiny butterfly-shaped organ in the neck that produces hormones that help regulate metabolism. In Hashimoto’s, the immune system attacks the thyroid gland, causing inflammation and damage that can lead to hypothyroidism (an underactive thyroid).

So, what are the symptoms of Hashimoto’s thyroiditis? Well, they can vary widely from person to person, but some common ones include:

  • fatigue
  • weight gain
  • cold intolerance
  • joint pain
  • depression
  • swelling in the neck, known as a goiter

Treatment for Hashimoto’s typically involves hormone replacement therapy, which can help replace the hormones that the thyroid gland is no longer producing. In some cases, medications that suppress the immune system may also be used to reduce inflammation and slow disease progression.

The good news is that most people with Hashimoto’s thyroiditis can manage their symptoms and lead full, healthy lives with proper treatment. So if you’re experiencing any of the symptoms mentioned above, don’t hesitate to contact your doctor and get checked out.

Rheumatoid Arthritis

Rheumatoid arthritis (RA) is another chronic autoimmune disorder that primarily affects the joints. This condition happens when the immune system attacks the synovium, the lining of the joints, leading to inflammation.

RA can cause many symptoms, but pain, swelling, and joint stiffness are common. These symptoms can be worse in the morning or after being still for a while. Over time, RA can damage the joints in a way that can’t be fixed, leading to deformities and other problems.

While the root cause of RA is not known, several risk factors can increase the likelihood of developing this condition. These include:

  • genetics
  • environmental factors
  • smoking 
  • obesity

RA can be treated in many ways, including with medicine, physical therapy, and changes in how you live. Getting early help is especially important to manage symptoms and stop joint damage.

Living with RA can be challenging, both physically and emotionally. However, managing symptoms and maintaining a good quality of life is possible with the right treatment and support.

Type 1 Diabetes

Type 1 diabetes is a chronic autoimmune disorder that happens when your immune system attacks the insulin-producing cells in the pancreas. Insulin is a hormone regulating blood sugar levels, so when these cells are destroyed, the body cannot properly control blood sugar.

The symptoms of type 1 diabetes include:

  • increased thirst
  • frequent urination
  • fatigue
  • weight loss

This condition is most commonly diagnosed in children and young adults but can occur at any age. Without treatment, this condition can lead to serious health complications, including nerve damage, kidney damage, and heart disease.

Insulin therapy is the main way to treat type 1 diabetes. Insulin can be put into the body through injections or an insulin pump. Also, changing your lifestyle, like eating well and working out regularly, can help you control your blood sugar levels.

Living with type 1 diabetes can be hard on your body and on your mind. People with this condition have to constantly check their blood sugar levels and make changes to their treatment based on what they find. But with the right care and support, dealing with the symptoms and maintaining a good quality of life is possible.


Psoriasis is a chronic autoimmune disorder that mainly affects the skin. This condition happens when the immune system attacks healthy skin cells, developing thick, scaly patches on the skin. These patches can be red, itchy, and painful and can occur anywhere on the body.

Even though no one knows for sure what causes psoriasis, it is thought to be a mix of genetics and the environment. Symptoms of psoriasis can also worsen when you’re stressed, hurt your skin, or have an infection. Psoriasis can sometimes lead to other problems, such as changes in the nails, eye issues, and psoriatic arthritis.

Psoriasis can be treated with creams and ointments that are put on the skin, light therapy, and oral pills. Managing stress and keeping a healthy weight can also help you deal with symptoms.

Multiple Sclerosis

Multiple sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system. This condition starts when the immune system attacks the myelin sheath, the protective covering around brain and spinal cord nerve fibers. This damage leads to a wide range of symptoms, including:

  • problems with vision
  • fatigue
  • muscle weakness and stiffness
  • difficulty with coordination and balance
  • numbness or tingling in the limbs

Some triggers of MS are infections, stress, and smoking. In severe cases, MS can make people very weak and unable to move.

There is no cure for MS right now, but several treatments can help manage symptoms and slow the disease’s progression. Medications reduce inflammation and immune system activity. Physical therapy improves mobility and strength. Counseling helps deal with the emotional effects of the condition and may be used as part of these treatments.

Living with MS can be hard on both your body and your mind. Because the disease is hard to predict, it can cause worry and fear. But with the right treatment and support, it is possible to deal with the symptoms and keep a good quality of life.

Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE), commonly known as lupus, is another chronic autoimmune disorder that can affect multiple organs and systems in the body. This condition starts when the immune system attacks healthy tissues and organs, leading to inflammation and damage.

No one knows what causes lupus, but it is thought to be a mix of genetics and the environment. Some things, like the sun, an infection, or a certain drug, can also cause symptoms to get worse.

Lupus symptoms can vary widely but often include the following:

  • fatigue
  • joint pain and swelling
  • skin rashes
  • fever
  • chest pain
  • kidney damage
  • lung problems

There is currently no cure for lupus, but there are many ways to help manage symptoms and avoid complications. Some of these treatments include taking medicine to lower inflammation and immune system activity and changing your lifestyle, such as staying away from triggers, eating well, and exercising regularly.

Celiac Disease

Celiac disease is an autoimmune disorder that targets the small intestine. This condition is triggered by consuming gluten, a protein found in wheat, barley, and rye.

When a person that suffers from celiac disease eats gluten, their immune system starts to attack the lining of their small intestine. This causes inflammation and damage to the digestive system. This can lead to a variety of symptoms, like:

  • abdominal pain
  • bloating
  • diarrhea
  • constipation
  • nausea

Celiac disease is often misdiagnosed because its symptoms look like those of other digestive problems. But if celiac disease isn’t treated, it can lead to severe problems like malnutrition, osteoporosis, and an increased risk of certain cancers.

Celiac disease can only be cured by following a strict gluten-free diet. This means staying away from all foods and products that contain wheat, barley, and rye. People with celiac disease may also need to stay away from oats since gluten can get into them when they are processed.

Living with celiac disease can be challenging, as gluten is found in many common foods and ingredients. But it is possible to eat healthily without gluten with the correct information and help.

People with celiac disease may also benefit from supplements to make up for any nutrients they may be missing because of the disease. For example, calcium and vitamin D supplements can help prevent osteoporosis, and iron supplements can treat anemia caused by being unable to absorb nutrients.


It can be hard to live with an autoimmune disorder. Still, it can be a chance to learn more about your body, make new friends, and find new ways to put your health and well-being first.

However, it’s important to remember that you are not alone. Autoimmune disorders affect millions of people around the world, and there are many ways to treat them to help with symptoms and improve quality of life.

If you think you have an autoimmune disorder, you should talk to your doctor to get a proper diagnosis and find out what treatments are available. There is no one-size-fits-all way to treat these conditions, whether it’s with medicine, changes to your lifestyle, or a mix of both.

Hi! I’m Dr. E, The NP with a PHD. Several years ago, my wife was diagnosed with an autoimmune disease and the only options given to us were heavy duty medications.

We KNEW there had to be a better way. After a long search, we discovered functional medicine.

With functional medicine we found alternative ways we were able to manage her disease and get her back to feeling like her old self.

We discovered that this way of life not only helps people with various issues, including autoimmune, chronic issues and “I-don’t-feel-good-itis.”

Functional medicine drastically changed our lives and using it I developed The KNEW Method to help others who are suffering or not feeling optimal.

Let’s work together to get you to feeling like your old self again.

Are You Tired of Being Tired?

Have You Been Told “It’s your age” or “It’s your hormones?”

Are People Telling You “Just Lose Weight” or “Just Exercise More?”

You KNOW That There Is Something More…

You KNOW There Is A Better Way

If you are suffering from one (or more) of these issues – chronic pain, high blood pressure, mental fog, fatigue, low energy, poor sleep, lack of focus, loss of libido, aches, pains, or general “I-don’t-feel-good-itis”… YOU HAVE COME TO THE RIGHT PLACE
