12 Most Common Symptoms of Lupus

2. Skin Rashes

You may notice skin rashes as one of the earliest and most visible signs of lupus. These rashes often appear on your face, especially across the cheeks and nose, forming what is called a “butterfly” or malar rash. It can also show up on other parts of your body that are exposed to the sun, like your arms or neck.

Some people experience flat, red patches, while others have raised or scaly areas. The rash can appear suddenly during disease flare-ups and may fade when symptoms calm down. Many people with lupus are sensitive to ultraviolet light, which can trigger inflammation of the skin. Using sunscreen and wearing protective clothing can help manage this sensitivity. Other forms of lupus-related rashes, such as cutaneous lupus, affect areas beyond the face. These rashes may cause skin discoloration, scarring, or hair loss if they occur on the scalp.

3. Hair Loss

You might notice hair thinning or patches of bald spots if you have lupus. The immune system causes inflammation around the hair roots and scalp, which leads to this symptom. In some cases, hair may fall out in clumps, while in others it gradually thins over time.

Lupus-related hair loss can occur during active disease periods, often called flares. During these times, swelling in the skin or scalp affects how hair grows. Some people also develop a rash or scarring on their scalp, which can make hair loss more visible.

Certain treatments used to control lupus symptoms, such as corticosteroids or immune-suppressing drugs, can sometimes contribute to hair thinning. When your doctor adjusts or stops these medicines under medical supervision, hair may begin to grow back.

You can manage hair care gently by avoiding tight hairstyles, chemical treatments, and too much heat. Using mild shampoos and keeping the scalp protected from the sun can also help maintain scalp health and support regrowth once inflammation is controlled.

4. Joint Pain

Joint pain is a common lupus symptom that causes aching, stiffness, or swelling, often affecting the hands, wrists, knees, and fingers. The discomfort may shift from one joint to another and is often worse in the morning or after long periods of rest.

Unlike some forms of arthritis, lupus-related joint pain rarely leads to permanent joint damage or deformities. However, during flares, joints may feel warm, tender, or mildly swollen, making daily movement more difficult. Your doctor may suggest anti-inflammatory or immune-suppressing medicines, physical therapy, or gentle exercise to help relieve discomfort.

5. Unexplained Fever

You may experience a fever with no clear cause when you have lupus. This often happens when your immune system becomes highly active and triggers inflammation in different parts of the body. Unexplained fever can make you feel weak or achy and may appear alongside other symptoms such as joint pain, fatigue, or swelling.

In some cases, it may be the first sign that lupus activity is increasing, signaling that your body is reacting to internal inflammation rather than an outside illness. A mild fever may fade on its own, while higher or longer-lasting fevers may need medical attention.

6. Dry Eyes and Mouth

You may notice your eyes or mouth feeling dry for long periods. Lupus affects the glands that make tears and saliva, leading to reduced moisture. This lack of moisture can make your eyes feel gritty or sore and cause problems with swallowing or speaking.

Dryness in these areas can lead to discomfort or infections. When your eyes are dry, you might rub them more often, which can make irritation worse. Dry mouth can increase the risk of tooth decay, gum problems, and mouth sores. Some people with lupus also develop a condition called secondary Sjögren’s syndrome.

This condition further reduces tear and saliva production, making symptoms more noticeable. You can ease symptoms by drinking water often and avoiding caffeine or alcohol. Using artificial tears or saliva substitutes may also help keep your eyes and mouth moist.

7. Headaches

You might notice that headaches are common if you have lupus. They sometimes resemble typical tension-type headaches with pressure in the head and neck, and other times feel more severe or last longer than expected.

These headaches often develop when inflammation affects the body or nervous system. During lupus flares, increased immune activity can create pressure or irritation around the head and neck. Stress, fatigue, and poor sleep can further intensify this response and make headaches more noticeable.

Some may feel migraine-like, causing throbbing pain or sensitivity to light that may be linked to immune activity or blood vessel inflammation. Sinus-related headaches can also occur, leading to pain in the face or forehead when inflammation affects the nasal areas.

8. Thyroid Problems

You may notice thyroid problems if you have lupus because both involve the immune system. When the immune system mistakenly attacks healthy cells, it can also affect the thyroid gland. This small gland in the neck produces hormones that control how your body uses energy. When the thyroid is affected, hormone levels can become unbalanced.

An underactive thyroid, called hypothyroidism, may cause tiredness, weight gain, dry skin, or feeling cold often. An overactive thyroid, called hyperthyroidism, can lead to weight loss, a fast heartbeat, sweating, or nervousness. These symptoms can overlap with lupus symptoms, making them easy to miss.

9. Chest Pain

If you have lupus, chest pain can develop when inflammation affects structures in the chest, such as the lungs, the tissue surrounding them, or the lining of the heart. This inflammation can irritate these tissues and cause pain that often feels sharp or achy rather than heavy like typical heart-related chest pain.

When the pleura, the thin tissue around the lungs, or the lining of the heart becomes inflamed, pain may worsen with deep breathing, coughing, or certain body positions, such as lying down. Some people may also feel short of breath or fatigued during these episodes.

The discomfort can range from mild to severe and may last for a short time or come and go over time. Because chest pain can also result from other causes, such as muscle strain or anxiety, any new or intense pain should be evaluated by a healthcare provider.

10. Stomach Pain

You might experience stomach pain if lupus affects your digestive system. When immune activity increases, inflammation can irritate digestive organs such as the stomach, intestines, or pancreas, leading to discomfort. This pain may range from mild to sharp cramps and can come and go or last longer over time.

As inflammation disrupts normal digestive function, you may notice bloating, nausea, a feeling of fullness after eating small amounts of food, or changes in appetite. Some medicines used to manage lupus, including anti-inflammatory or immune-suppressing drugs, can further irritate the stomach lining. This irritation may cause a burning sensation, especially after meals.

11. Cold Extremities

Cold fingers or toes can occur in lupus when changes in blood vessel function affect circulation. In response to cold temperatures or stress, small blood vessels in the fingers and toes tighten, which reduces blood flow to these areas. This reduced circulation leads to Raynaud’s phenomenon, a reaction that affects the fingers and toes.

During an episode, the skin may turn white or bluish as blood flow drops, then red as circulation returns during warming. You may also feel tingling, numbness, or mild pain while this happens. Keeping your body warm helps prevent symptoms. You can wear gloves, warm socks, and layers to protect your skin from cold air or sudden temperature changes.

12. Kidney Issues

Lupus can sometimes affect your kidneys, a condition known as lupus nephritis. This occurs when the immune system mistakenly attacks structures in the kidneys that filter waste from the blood. The resulting inflammation interferes with normal filtering and, over time, can reduce how well the kidneys function.

As kidney filtering becomes impaired, protein may leak into the urine and fluid can build up in the body. You might notice swelling in the feet, ankles, or legs, along with urine that appears foamy or contains blood. These signs suggest that the kidneys are under stress.

Doctors assess kidney function through urine and blood tests that measure protein levels, creatinine, and other indicators of filtration. In some cases, a kidney biopsy may be needed to identify the extent and type of damage.
