Lupus is a chronic inflammatory disorder that develops when your organs and tissues are attacked by your own immune system. Lupus causes inflammation in numerous organs, such as the heart, skin, blood cells, joints, lungs, brain, and kidneys.
It can be quite hard to diagnose lupus since its signs and symptoms are similar to those of other conditions. A facial rash that looks like butterfly wings, specifically on the cheeks, is a unique sign of lupus. Although not all people with lupus experience this sign, it is very common.
Certain individuals are naturally prone to lupus. A few drugs, infections, and even sunlight can trigger lupus symptoms. Although lupus has no cure, its symptoms can be controlled with treatments. However, the majority of lupus symptoms resemble those of other conditions and can appear and disappear over the course of a few months. It may even take years to successfully diagnose lupus.
For lupus to be diagnosed, the doctor needs to have laboratory results or physical proof of the ailment, such as proteinuria (the presence of protein in the urine), swelling of the joints, and fluid surrounding the heart or lungs. These health conditions are indicative of lupus.
The butterfly rash, or malar rash, which is also known as acute cutaneous lupus, is one of the four types of lupus related to the skin. Malar is derived from the Latin word “mala,” which means "cheekbone." A butterfly-shaped rash across the cheeks is the most visible sign of lupus. It could develop suddenly or appear after sunlight exposure. About 50% of people with lupus have a butterfly rash. The rashes on the cheeks are mostly red or purple in color and can appear in a blotchy pattern or be completely red, covering the affected area. The area itself can be flat or slightly raised.
The lupus butterfly rash is typically painless and does not itch. However, at times, it can cause itchiness if it appears more like a rash rather than a blush. There have been some instances wherein patients complain of a “hot” feeling when the malar rash becomes severe. Along with inflammation of other organs, the lupus butterfly rash can be triggered by photosensitivity, which is a condition worsened by exposure to sunlight.
The rash gets its name from its resemblance to a butterfly, which spans the width of the face, covering both cheeks and the bridge of the nose. The butterfly rash may appear on its own, but some people observe that the occurrence of the butterfly rash is a sign of an oncoming disease flare. Whatever the case, it is important to pay attention to the body’s signals and notify the doctor of anything unusual. Studies have revealed that malar rash is mostly seen in people suffering from a type of lupus known as systemic lupus erythematosus (SLE).
Lupus mainly affects the body’s immune system. The immune system usually generates proteins known as antibodies, which guard the body from unfamiliar invaders. The immune systems of people with lupus are unable to differentiate between healthy body tissues and foreign invaders. Autoantibodies that destroy healthy tissues are then produced. These autoantibodies produce pain, inflammation, and damage in different parts of the body.
Doctors usually look for signs of inflammation such as redness, pain, swelling, and heat. Inflammation can take place outside of the body, on the skin, or in the heart and kidneys.
Lupus is diagnosed according to blood tests, symptoms, and a physical evaluation. Other conditions can also be ruled out by specific tests.
It is not yet clear what exactly causes lupus. However, studies indicate that its development is a response to a variety of factors that involve both the inside and outside of the human body. Factors include genetics, hormones, and the environment.
- Genetics: There is no specific gene or group of genes known to cause lupus. The prevalence of lupus has been observed in some families and certain genes, which have been identified as a contributing factor for the development of this medical condition. Moreover, there are chances of lupus even in individuals with no family history of the condition. Africans, Native Americans, Asians, and Hispanics are known to be at a greater risk of developing lupus.
- Hormones: Hormones are chemical substances produced by the body. They are known to regulate or control the activity of specific cells or organs. Lupus is mostly seen as a more common occurrence in women than in men. Studies show that women experience lupus symptoms just before their menstrual periods or during pregnancy, when the production of estrogen levels are high in the body.
- Environment: Studies indicate that there are certain environmental agents, such as a virus or chemicals, that could trigger lupus in an individual. Some of those triggers include infections, colds, ultraviolet rays, exposure to silica, stress, exhaustion, injury, and smoking.
The following are the most common symptoms of lupus:
- Hair falling out or hair loss
- Joint pain
- Dry mouth
- Inflammation of the kidneys
- Pulmonary issues
- Thyroid problems
- Dry eyes
- Gastrointestinal complications
- Mysterious fevers
You will probably not experience all lupus symptoms. The majority of individuals with lupus only have the leading symptoms. Less common symptoms of the condition include:
- High body temperature
- Swollen lymph glands
- Frequent mouth ulcers
- Hypertension (high blood pressure)
- Abdominal pain
- Memory loss
- Migraines and headaches
- Feelings of confusion
- Edema, or swelling in the leg, ankles, or around the eyes
- Chest pain
- Psychosis (inability to differentiate between imagination and reality)
- Raynaud's disease (poor supply of blood to the feet and hands during cold times)
A lupus diagnosis takes into account a number of factors since the condition can resemble other ailments. They include:
- Complete medical history of the individual. It is important to inform your doctor regarding your past health issues and the medications you have taken.
- Signs and symptoms: A complete medical evaluation, including an analysis of all your current symptoms
- Results of a physical evaluation
- Analysis of tests linked to the status of the immune system. Additionally, your doctor may order several tests to help confirm if you suffer from an autoimmune condition.
- Analysis of standard laboratory test results
Lupus can be diagnosed through various blood tests. The following are laboratory tests for the diagnosis of lupus:
- ANA (antinuclear antibody) test: Approximately 95% of individuals who have lupus are ANA-positive. However, the results can at times show positive in individuals who do not have the condition. Thus, a lupus diagnosis cannot be confirmed using only this type of test.
- Anti-dsDNA (anti-double stranded DNA) test: Approximately 70% of individuals with lupus possess these antibodies. Since it is rare for the test to turn out positive in individuals without lupus, a positive result will signify a high probability of lupus. The level of anti-dsDNA normally rises when lupus is very active. Hence, it can be beneficial to have recurring tests as a way of observing the condition and settling on an appropriate treatment.
- Anti-Ro antibody test: If this test turns out positive, you will have a high chance of developing skin rashes and will experience dry mouth or dry eyes. During pregnancy, this autoantibody can go through the placenta. Your pregnancy will be strictly watched if you have the anti-Ro autoantibody, especially if you decide to carry the pregnancy to term.
- Antiphospholipid antibody test: If you test positive for these autoantibodies, you will be more prone to developing blood clots or miscarriages.
- Complement test: Complement proteins are contained in the blood and guard your body against infectious attacks. When lupus is very active, the level of complement goes down.
- ESR (Erythrocyte sedimentation rate): An assessment of inflammation can be done by calculating how fast the blood cells reach a test tube’s bottom. In lupus, the ESR is mostly raised.
- Liver and kidney function tests: These tests involve routine blood and urine examinations to identify and immediately deal with any complications arising from lupus treatments. The presence of blood or protein in the urine can be identified in a urine test. A urine test will assist in the early detection of kidney complications. If there is need, a test for kidney filtration may be performed. A biopsy is the most effective method for determining the degree of kidney damage. It may be recommended for individuals with kidney test irregularities.
- Blood cell counts: Red and white blood cells, platelets, and hemoglobin are produced in the bone marrow. Therefore, blood cell counts can assist in determining if there is damage in the bone marrow, caused either by medications for treating the disease or the disease itself.
After the diagnosis, these tests can help in observing the disease. For instance, a blend of dropping complement levels and high anti-dsDNA levels can be used to forecast lupus breakouts. When the CRP is raised, your doctor will look for the chance of an infection.
To determine the condition of your liver, heart, spleen, and lungs, you can undergo a wide range of tests. A CT scan, MRI, ultrasound, or X-ray may be performed depending on the organs in question. It is important to head in for regular checkups and to have your body scanned regularly, since it can help you identify any key issues and allow you to take effective measures in treating them.
If you experience symptoms such as persistent lymph gland swelling, weight loss, or fever, a biopsy may be recommended to ensure you do not have cancer, which could also be the origin of your symptoms.
Your doctor may recommend the following if they think your heart or lungs are being affected by lupus:
- Echocardiogram: This is a test that generates instantaneous pictures of your beating heart using sound waves. It can look for issues with the valves and other areas of the heart.
- Chest X-ray: An image of your chest that shows irregular shadows can imply inflammation or fluid in the lungs.
The kidneys can also be affected by lupus in various ways. Treatment can differ according to the type of kidney damage. At times, there will be a need to check the kidney tissues to decide on the appropriate treatment. Through a tiny cut, a needle is used to obtain a sample. The sample is then tested to gauge the right treatment to use and to deal with the underlying condition effectively.

Drugs used to treat malaria can also be used for lupus. The side effects associated with these medications often range from an upset stomach to retinal issues, although the latter is rare. Corticosteroids can go a long way towards alleviating lupus symptoms, but they can also cause bruising, high blood pressure, diabetes, and bone thinning.
The severity of these side effects depends more on the dosage and the duration of treatment.
6) Can you recommend any specialists for the treatment of lupus?

Natural Remedies for Lupus
- Anti-inflammatory foods: Having a healthy diet is important for people diagnosed with lupus. A healthy diet can help control inflammation caused by poor gut health. In addition, it can lower the risk of developing complications such as heart disease. It also lessens the side effects of medications and helps build energy and strength. Recommended foods for people with lupus include organic and unprocessed foods, raw vegetables, fish, high-antioxidant foods, and bone broth. Drinking plenty of fluids and consuming coconut or olive oil are also beneficial. Apart from these, there are certain foods that can provide relief from skin dryness and irritation, which are very common with lupus. These foods help moisturize the skin inside and out and include avocados, melon, cucumbers, olive oil, coconut oil, walnuts, almonds, chia seeds, and flaxseeds. An individual suffering from lupus should avoid certain foods that could worsen their condition. Such foods include gluten-enriched foods, sugary products, caffeinated drinks, alcohol, salty foods, and foods with trans fats and saturated fats.
- Regular exercise: Doing regular physical activity can help a person recover from lupus flares, fight depression, lower the risk of a heart attack, and promote optimal well-being. Regular exercise also promotes good sleeping patterns, makes the lungs and heart stronger for better functioning, strengthens the bones, reduces pain in the joints, and reduces any health-related complications. However, one should start slowly without exerting too much pressure on any part of the body. Overexertion is always harmful and can worsen one's existing medical condition. It is also important to give yourself enough rest in between workouts so the muscles can build up and recover again from the physical strain. Exercises that are considered beneficial for people suffering from lupus are swimming, brisk walking, yoga, cycling, Pilates, and aerobics.
- Adequate rest: People with lupus often experience fatigue or tiredness. Their level of fatigability is much higher compared to normal people. Thus, having plenty of sleep at night and taking naps during the day are important.
- Reducing stress: Emotional and psychological stress often lead to lupus flare-ups that can worsen the condition. There are different kinds of stress relievers suited for different people. Yoga, meditation, and acupuncture have provided numerous benefits for the health of the immune system. One can also practice breathing techniques, praying, and exercising to keep stress at bay.
Protecting the skin: There is one type of lupus called cutaneous lupus erythematosus that is known to create a wide variety of dermatologic signs and symptoms. Due to the inflammatory response, skin rashes are prone to occur with lupus, hence, it is very important to protect the skin from certain irritants. Take precautionary measures by:
- Avoiding direct exposure to the sun
- Applying non-toxic sunscreen lotions
- Always wearing sunglasses
- Wearing protective clothes if you need to be out in the sun
- Avoiding hot showers during the summer
- Taking the recommended vitamins for lupus
Risk and Complications
Lupus can also lead to certain complications if treatment is not carried out in time:
- Pregnancy: Pregnant women with lupus have an increased risk of miscarriage. Lupus is known to increase the risk of high blood pressure during pregnancy as well. To avoid such instances and to reduce the risks, doctors often suggest delaying pregnancy until the medical condition is under control with the help of treatment for a period of at least six months.
- Infections: Lupus is known to impair the immune system, thereby causing a rise in infections. The medical condition and its treatment are both known to increase the risk of having a weak immune system. Infections that most commonly affect people suffering from lupus are yeast infections, urinary tract infections, respiratory infections, herpes, and shingles.
- Avascular necrosis (AVN): AVN is also known as bone tissue death, wherein the supply of blood to the bone reduces. It gradually leads to tiny breaks or cracks in the bone, leading to a collapse in bone structure. The most commonly affected area is the hip joint.
- Lupus is a chronic inflammatory disorder that develops when your organs and tissues are attacked by your own immune system.
- It can be hard to diagnose lupus since its signs and symptoms are similar to those of other conditions.
- Lupus is diagnosed according to blood tests, symptoms, and physical evaluation.
