Autoimmune Diseases

Autoimmune diseases, a complex group of disorders, arise when the body’s immune system, responsible for safeguarding against harmful invaders, erroneously turns against its healthy cells and tissues. This perplexing phenomenon leads to many conditions where the immune system mistakenly identifies self-components as foreign entities, triggering an inflammatory response. Consequently, autoimmune diseases can affect various organs and systems, causing multiple symptoms that vary in severity and intensity. Over 80 different autoimmune diseases have been identified, including rheumatoid arthritis, multiple sclerosis, type 1 diabetes, and systemic lupus erythematosus, each with distinct manifestations. The complexity of these conditions must be understood to create effective therapies and raise the standard of living for the millions of people affected worldwide.

What are Autoimmune Diseases?

Organs and cells that make up your immune system are intended to defend your body against viruses, bacteria, parasites, and cancerous cells. An autoimmune disease develops when your immune system unintentionally attacks your body rather than protecting it. Why your immune system does, this is unknown.

Over a hundred autoimmune disorders are recognized. Lupus, rheumatoid arthritis, Crohn’s disease, and ulcerative colitis are examples of common ones. Numerous tissue types and almost every organ in your body are susceptible to autoimmune disorders. They may bring multiple symptoms, including discomfort, exhaustion, rashes, nausea, migraines, dizziness, and more. The exact ailment determines the specific symptoms.

Common Types of Autoimmune Diseases

Researchers have discovered more than 100 autoimmune illnesses. Here are 14 additional typical ones.

Diabetes type 1

Your pancreas and aids create the hormone insulin in controlling blood sugar levels. Your pancreas’s insulin-producing cells are destroyed when you have type 1 diabetes by your immune system.

The blood vessels and organs might become damaged by type 1 diabetes high blood sugar levels. This may apply to you:

  • Heart
  • Kidneys
  • Eyes
  • Nerves

Rheumatoid Arthritis (RA)

RA is another example. Your immune system targets your joints if you have RA. This results in symptoms that affect the joints, including:

  • Swelling
  • Warmth
  • Soreness
  • Stiffness

Although RA often affects people as they age, it can sometimes begin as early as your 30s. Juvenile idiopathic arthritis, a disorder similar to this, can start in childhood.

Psoriatic Arthritis/ Psoriasis

Skin cells multiply and finally shed when they are no longer needed. In psoriasis, skin cells proliferate too quickly. Patches of inflammation are produced as extra cells build up. On lighter skin tones, patches with silver-white plaque scales may seem red. On deeper skin tones, psoriasis can include purplish or dark brown scales.

Up to 30%Many people who have psoriasis go on to acquire psoriatic arthritis. This may result in joint symptoms like:

  • Swelling
  • Stiffness
  • Pain

Multiple Sclerosis

Multiple sclerosis (MS) damages the myelin sheath, which covers the nerve cells in your central nervous system. Damage to the myelin sheath slows the rate at which impulses go between your brain, spinal cord, and the rest of your body.

This harm may result in:

  • Weakness
  • Problems with balance
  • Numbness
  • Difficulty walking

Different types of MS develop at various speeds. One of the most typical MS mobility concerns is difficulty walking.

Systemic Lupus Erythematosus (SLE)

Due to the typical rash, it causes, doctors initially thought of lupus as a skin condition in the 1800s. However, the systemic type, which is the most prevalent, actually affects several organs. This may apply to you:

  • Joints
  • Kidneys
  • Brain
  • Heart

Typical signs may include:

  • Joint pain
  • Exhaustion
  • Rashes

Colitis of the Bowels

IBD refers to medical diseases that lead to intestinal wall lining inflammation. Different parts of your gastrointestinal (GI) tract are affected by various IBD types. Crohn’s disease can inflate any area of your GI tract, including the anus and the mouth. The rectum and colon lining are both impacted by ulcerative colitis.

IBD symptoms frequently include:

  • Constipation
  • Abdominal discomfort
  • Bleeders on the skin

Addison’s Disease

Addison’s disease affects the adrenal glands, which produce androgen hormones and cortisol, aldosterone, and other hormones. Low cortisol levels affect how your body consumes and stores sugar (glucose) and carbs. A lack of aldosterone can cause excessive potassium and salt loss in the blood.

Addison’s disease’s common signs and symptoms include:

  • Weariness
  • Weakness
  • Weight loss
  • Low blood sugar

Grave’s Illness

Graves’ illness attacks the thyroid gland in your neck, causing it to overproduce hormones. Thyroid hormones control how much energy the body uses during its metabolism.

When you have too much of these hormones, your body works harder, and you may have symptoms like:

  • (Tachycardia) a quick heartbeat
  • Heat sensitivity
  • Unintended loss of weight
  • Goiter is a swelling of the thyroid gland
  • Graves’ dermopathy and ophthalmopathy are additional symptoms that some persons with Graves’ illness may encounter.

Sjögren’s Syndrome

This illness affects the glands that lubricate your tongue and eyes. Dry mouth and eyes are the typical signs of Sjögren’s illness. However, your skin or joints may also be affected.

Hashimoto’s Thyroiditis

Hashimoto’s thyroiditis results in a shortage in thyroid hormone production. Typical signs of Hashimoto’s thyroiditis include the following:

  • Gaining weight
  • Weariness from the cold hair loss
  • Thyroid enlargement (goitre)

Myasthenia Gravis

Myasthenia gravis affects nerve signals that help the brain govern muscular movement. Calls cannot trigger the muscles to contract when the nerves and muscles cannot communicate.

The most common symptom is weakness in the muscles. Activity may make it worse, and rest may make it better. Having weak muscles can have an impact on the following:

  • Eyes moving
  • Eyes that open and close
  • Swallowing
  • Facial gestures

Celiac Disease

For those with celiac disease, it is forbidden to consume foods containing gluten, a protein found in wheat, rye, and other grain products. The small intestine is targeted and becomes inflamed by the immune system when gluten is present there.

After consuming gluten, those who have celiac disease may develop digestive problems. Some symptoms include:

  • Vomiting
  • Diarrhea
  • Constipation
  • The abdomen bleeds

Vasculitis autoimmune

When your immune system targets blood vessels, autoimmune vasculitis develops. Your arteries and veins become more constricted due to the ensuing inflammation, which reduces blood flow.

Acute Myeloid Leukemia

Pernicious anaemia can occur when your body doesn’t create enough of a substance called intrinsic factor due to an autoimmune illness. The quantity of vitamin B12 your small intestine absorbs from food increases if you have enough of this component. A low red blood cell count may result from it.

You’ll get anaemia if you don’t get enough of this vitamin, and your body won’t be able to synthesize DNA properly. It may result in symptoms like:

  • Fatigue
  • Weakness
  • Headaches
  • Ages 60 to 70 are the average onset years for this uncommon autoimmune disease.

Causes of Autoimmune Diseases

The actual cause of immune system dysfunction is unknown to doctors. But some persons are more prone to autoimmune disease development than others. Some elements that may raise your risk of contracting an autoimmune illness include:

Your Sex

Between the ages of 15 and 44, persons born female are more likely to develop an autoimmune disease than people born male.

Your Family’s Genealogy

Inherited genes may increase your risk of developing autoimmune illnesses, while environmental variables may also play a role.

Environmental Factors

Certain bacterial and viral infections, like COVID-19Trusted Sources, sunshine, mercury, chemicals like solvents or those used in agriculture, cigarette smoke, and other infectious agents, can raise your risk of developing an autoimmune illness.


People in particular groups have higher rates of some autoimmune illnesses. For instance, autoimmune muscle disease may be more common in White individuals from Europe and the United States, whereas lupus is more common in African Americans, Hispanics, and Latinos.


Your food and nutritional intake may affect the risk and severity of autoimmune illness.

Additional Medical Conditions

Obesity and other autoimmune illnesses may increase your risk of developing an autoimmune disease.

Symptoms of Autoimmune Diseases

Even while autoimmune diseases come in many forms, many have comparable symptoms. The following are typical signs of autoimmune disease:

  • Fatigue
  • Aching and swollen joints
  • Skin conditions
  • Stomach aches or digestive problems
  • Persistent fever
  • Enlarged glands

It can be challenging to get diagnosed, as many women claim. “It’s not black or white. To diagnose autoimmune illness, there typically isn’t a single test. It would be best to exhibit particular symptoms with specific blood indicators and, in some circumstances, even a tissue biopsy. It involves more than one thing.

Diagnosis can be challenging because other prevalent illnesses might also cause these symptoms. It is better for women to get help if they develop any new symptoms.

You don’t minimize your fatigue or joint stiffness if you’ve been healthy and you suddenly feel them. Letting your doctor know about your symptoms enables them to investigate further and order testing to find or rule out an autoimmune condition.

Risk Factors of Autoimmune Diseases

Although the exact cause of the autoimmune disease is unknown, numerous theories suggest that it develops due to an overactive immune system attacking the body after an infection or damage. We are aware that some risk factors, such as the following, raise the possibility of developing autoimmune disorders:


Multiple sclerosis (MS) and lupus are two diseases that frequently run in families. Having an autoimmune disease in a family member raises your risk, but it doesn’t guarantee you will get it.


A large waistline increases your chances of psoriatic or rheumatoid arthritis. This might be because carrying extra weight puts more strain on the joints or because fat tissue produces inflammatory molecules.


Studies have connected smoking to several autoimmune conditions, such as lupus, rheumatoid arthritis, hyperthyroidism, and multiple sclerosis (MS).

Drugs and Medicines

Certain medicines Drug-induced lupus, which is frequently a more benign type of the disease, can be triggered by some antibiotics or blood pressure drugs. Our myositis center also learned that certain cholesterol-lowering medicines called statins can cause statin-induced myopathy. Muscle wasting is an uncommon autoimmune condition known as myopathy. But be sure to see your doctor before beginning or quitting any medications.

Diagnosis of Autoimmune Diseases

Healthcare professionals typically need more time to diagnose an autoimmune disease than they need to diagnose other disorders. This is because many autoimmune diseases share symptoms and other illnesses. Bring the following items to your appointment to assist your doctor in the diagnosis process:

  • A thorough list of any symptoms you may have and how long you’ve had them.
  • A history of the health in your family. Make a note of any autoimmune disease sufferers in your family.

Your doctor may do a few blood tests to look for autoimmune illnesses in addition to speaking with you about your symptoms. These tests include:

  • Test for anti-nuclear antibodies (ANA).
  • (CBC) Complete blood count.
  • ESR, or erythrocyte sedimentation rate.

You can demonstrate that you have an autoimmune disease by combining certain symptoms with specific blood signs.

Treatment of Autoimmune Diseases

Autoimmune disorders have no known treatments. However, symptoms can be controlled. Each person has a unique immune system, genetic makeup, and environment. As a result, your treatment must be unique.

The following are some examples of drugs used to treat autoimmune diseases:

  • Painkillers
  • Inflammatory drugs
  • Medications for anxiety and sadness
  • Shots of insulin
  • Medicines for sleep
  • Plasma transfers
  • Corticosteroids
  • Tablets and lotions for rashes
  • Immune globulin is given intravenously
  • Medications that calm (suppress) your immune system

Some people experiment with complementary and alternative therapies. Examples comprise:

  • Herbs
  • Acupuncture
  • Hypnosis
  • Chiropractor techniques

Prevention of Autoimmune Diseases

There may be no way to stop autoimmune disorders from occurring. However, some authorities advise that you try the following:

  • Exercising regularly
  • Refraining from smoking
  • Eliminating poisons
  • Consuming a balanced diet
  • Reducing your consumption of processed meals

Final Thoughts

In conclusion, autoimmune diseases represent a complex and multifaceted group of disorders that continue to challenge the medical community. The intricate interplay between genetic predisposition and environmental triggers remains a research focus as scientists strive to unravel the underlying mechanisms responsible for these conditions. While significant progress has been made in diagnosing and managing autoimmune diseases, there is still much to learn. Advancements in immunology, genetics, and personalized medicine offer hope for more targeted and effective treatments in the future. Raising awareness about these conditions is crucial to fostering empathy and understanding among the general population. By supporting ongoing research and promoting early detection, we can collectively strive towards better outcomes and improved quality of life for those with autoimmune diseases. We can pave the way for a brighter and healthier future for affected individuals worldwide through collaboration, education, and advocacy.
