Scleroderma, also known as systemic sclerosis, is a chronic autoimmune disease characterized by the hardening and tightening of the skin and connective tissues. The term “scleroderma” literally means “hard skin” in Greek. This condition occurs when the immune system mistakenly attacks healthy tissue, leading to excessive collagen production that causes skin thickening and can affect internal organs.
Understanding the symptoms of scleroderma is crucial for early diagnosis and proper management. The condition can range from localized forms affecting only the skin to systemic forms that impact multiple organs including the heart, lungs, kidneys, and digestive system. While there is no cure for scleroderma, recognizing the warning signs early can help patients receive appropriate care and improve their quality of life.
In this comprehensive guide, we’ll explore the ten most common symptoms of scleroderma, helping you understand what to look for and when to consult a healthcare professional.
1. Skin Hardening and Tightening
The most characteristic symptom of scleroderma is the hardening and tightening of the skin. This occurs due to excessive collagen buildup in the skin tissue, making it thick, shiny, and difficult to pinch or fold. The hardening typically begins in the fingers and hands before potentially spreading to the arms, face, and trunk.
In the early stages, the affected skin may appear swollen or puffy before becoming tight and hard. The skin may lose its natural elasticity and take on a waxy or shiny appearance. Patients often describe the sensation as if their skin is too tight for their body. This tightening can restrict movement and make everyday tasks like bending fingers or making facial expressions challenging.
The extent and location of skin hardening help doctors classify the type of scleroderma. Limited scleroderma typically affects the skin on the hands, arms, and face, while diffuse scleroderma can involve larger areas of the body including the chest and abdomen.
2. Raynaud’s Phenomenon
Raynaud’s phenomenon is often the first symptom of scleroderma, sometimes appearing years before other signs develop. This condition causes the fingers and toes to change color in response to cold temperatures or emotional stress. The affected areas typically turn white, then blue, and finally red as blood flow returns.
During a Raynaud’s attack, blood vessels in the extremities constrict excessively, temporarily reducing blood flow. This can cause numbness, tingling, or pain in the affected fingers or toes. Episodes usually last from a few minutes to several hours. When blood flow returns, the area may throb or tingle intensely.
While Raynaud’s phenomenon can occur independently in healthy individuals, when associated with scleroderma it tends to be more severe. In some cases, reduced blood flow can lead to digital ulcers (sores on the fingertips) or, in rare instances, tissue damage requiring medical intervention. Most people with systemic scleroderma experience Raynaud’s phenomenon at some point.
3. Facial Changes
Face scleroderma can cause distinctive changes in facial appearance that develop gradually over time. The skin on the face becomes tight and less flexible, leading to a mask-like appearance with reduced ability to form facial expressions. The lips may become thinner and develop vertical lines radiating from the mouth.
The tightening skin can cause the nose to become more pointed or beaked in appearance. The mouth opening may become smaller, a condition called microstomia, which can make dental care, eating, and oral hygiene more difficult. Some patients also experience tightening of the skin around the eyes, giving them a more wide-eyed appearance.
These facial changes can affect not only appearance but also function. Patients may have difficulty opening their mouth wide enough for dental procedures or eating certain foods. The skin may also develop telangiectasias (small dilated blood vessels) that appear as red spots on the face, particularly on the cheeks and around the mouth.
4. Digestive Problems
Systemic scleroderma frequently affects the digestive system, with the esophagus being the most commonly involved organ. Hardening of the esophageal tissue weakens the lower esophageal sphincter, the valve that prevents stomach acid from flowing back into the esophagus. This leads to gastroesophageal reflux disease (GERD), causing heartburn, acid reflux, and difficulty swallowing.
Patients may experience a sensation of food getting stuck in the chest or throat when swallowing. Chronic acid reflux can damage the esophageal lining over time, potentially leading to complications such as strictures (narrowing of the esophagus) or Barrett’s esophagus. Many patients report that symptoms worsen when lying down or after eating certain foods.
Scleroderma can also affect other parts of the digestive tract. The stomach may empty more slowly (gastroparesis), causing bloating, nausea, and early satiety. The intestines can develop reduced motility, leading to constipation, diarrhea, bloating, and cramping. In some cases, bacterial overgrowth in the small intestine can cause additional digestive symptoms and nutritional deficiencies.
5. Joint Pain and Stiffness
Many people with scleroderma experience joint pain, stiffness, and swelling, particularly in the hands, wrists, and knees. The stiffness is often most severe in the morning or after periods of inactivity. This occurs because the connective tissue around joints becomes inflamed and thickened, restricting normal movement.
The tightening of skin over joints can further limit range of motion. Fingers may become difficult to fully extend or flex, and the hands can gradually curl into a claw-like position. This can significantly impact fine motor skills needed for activities like writing, buttoning clothes, or using utensils.
Joint involvement in scleroderma differs from rheumatoid arthritis, though both are autoimmune conditions. While inflammation plays a role, the primary issue in scleroderma is fibrosis (excessive tissue scarring) rather than joint destruction. Over time, some patients develop contractures, where joints become permanently fixed in bent positions due to severe tissue tightening.
6. Shortness of Breath and Lung Problems
Pulmonary complications are among the most serious manifestations of systemic scleroderma and a leading cause of illness in these patients. Two main lung problems can occur: interstitial lung disease (scarring of lung tissue) and pulmonary arterial hypertension (high blood pressure in the arteries of the lungs).
Interstitial lung disease develops when scleroderma causes inflammation and fibrosis in the lung tissue, making the lungs stiff and less able to expand properly. This results in progressive shortness of breath, particularly during physical activity. Patients may notice they become winded more easily than before, even with routine activities like climbing stairs or walking short distances. A persistent dry cough is another common symptom.
Pulmonary arterial hypertension occurs when the blood vessels in the lungs become narrowed and stiff, forcing the heart to work harder to pump blood through the lungs. This can cause shortness of breath, fatigue, chest pain, dizziness, and fainting spells. Both lung conditions require regular monitoring and medical management to prevent progression.
7. Kidney Problems
Although less common than in the past due to improved treatments, kidney involvement remains a serious potential complication of scleroderma. The most severe form is scleroderma renal crisis, a sudden onset of severe high blood pressure that can rapidly damage the kidneys.
Symptoms of kidney problems in scleroderma may include sudden severe headaches, visual changes, seizures, shortness of breath, and decreased urine output. The blood pressure may rise dramatically over a short period. Some patients may experience swelling in the legs and feet due to fluid retention. In severe cases, kidney function can deteriorate rapidly, potentially leading to kidney failure.
Not all kidney involvement in scleroderma is dramatic. Some patients develop more gradual kidney problems with subtle symptoms or no symptoms at all, which is why regular blood pressure monitoring and kidney function tests are important for people with systemic scleroderma. Early detection and intervention are crucial for protecting kidney function.
8. Fatigue and Weakness
Overwhelming fatigue is one of the most common and debilitating symptoms reported by people with scleroderma. This is not ordinary tiredness that improves with rest, but rather a profound exhaustion that interferes with daily activities and quality of life. The fatigue can be both physical and mental, making it difficult to concentrate or maintain energy throughout the day.
Multiple factors contribute to fatigue in scleroderma. The chronic inflammation associated with autoimmune disease places significant stress on the body. Poor sleep quality due to pain, itching, or digestive symptoms can prevent restorative rest. Reduced lung or heart function may limit oxygen delivery to tissues. Additionally, the psychological burden of living with a chronic illness can contribute to exhaustion.
Some patients describe the fatigue as coming in waves, with periods of relatively normal energy alternating with times of extreme tiredness. The unpredictability of fatigue can make it difficult to plan activities or maintain work schedules. Many people find they need to pace themselves carefully and prioritize activities to manage their limited energy reserves.
9. Calcinosis
Calcinosis refers to the development of calcium deposits under the skin, a symptom that occurs in some people with scleroderma, particularly those with limited systemic sclerosis. These deposits can range in size from tiny specks to larger lumps and typically appear on the fingers, hands, elbows, and knees, though they can develop anywhere on the body.
The calcium deposits feel like hard bumps under the skin and may be visible as white or yellowish nodules. While small deposits may cause no symptoms, larger ones can be painful, limit movement, or cause skin irritation. The overlying skin may become thin and fragile, and the deposits can sometimes break through the skin surface, creating open sores that may leak a white, chalky material.
When calcinosis breaks through the skin, there is a risk of infection. The wounds can be slow to heal and may be painful. Calcinosis deposits near joints can interfere with movement and function. While calcinosis doesn’t occur in everyone with scleroderma, when present it can significantly impact quality of life and daily functioning.
10. Telangiectasias
Telangiectasias are small dilated blood vessels that appear as red spots or lines on the skin surface. In scleroderma, these are most commonly seen on the face, particularly the cheeks and around the nose and mouth, as well as on the hands and chest. They are more common in limited scleroderma and are part of the CREST syndrome acronym (Calcinosis, Raynaud’s phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia).
These visible blood vessels typically measure between 1-3 millimeters in diameter and appear as tiny red dots or spider-like patterns. Unlike a rash, telangiectasias blanch (turn white temporarily) when pressed. They are not usually painful or itchy, but many people find them cosmetically concerning, especially when they appear on visible areas like the face.
The number and size of telangiectasias often increase over time in people with scleroderma. While they are primarily a cosmetic concern and don’t cause serious health problems, their presence can be a visible reminder of the disease. In some cases, telangiectasias can bleed if injured, though this bleeding typically stops easily with gentle pressure.
Main Causes of Scleroderma
The exact cause of scleroderma remains unknown, but researchers believe it results from a combination of genetic, environmental, and immune system factors. Understanding these potential causes can provide insight into this complex condition.
Autoimmune Dysfunction: Scleroderma is fundamentally an autoimmune disease, meaning the immune system mistakenly attacks the body’s own tissues. This abnormal immune response triggers inflammation and stimulates fibroblasts (cells that produce collagen) to create excessive amounts of collagen, leading to tissue hardening and scarring.
Genetic Predisposition: While scleroderma is not directly inherited, genetic factors appear to increase susceptibility. Certain genes related to immune function are more common in people with scleroderma. Having a family member with scleroderma or another autoimmune disease slightly increases risk, though most people with scleroderma have no family history of the condition.
Environmental Triggers: Various environmental factors may trigger scleroderma in genetically susceptible individuals. Exposure to certain chemicals and substances has been associated with scleroderma-like conditions, including silica dust, organic solvents, certain chemotherapy drugs, and vinyl chloride. However, most people exposed to these substances do not develop scleroderma.
Vascular Abnormalities: Blood vessel damage appears to be an early event in scleroderma development. Injury to the cells lining blood vessels may trigger the cascade of events leading to fibrosis and tissue hardening. This vascular involvement explains symptoms like Raynaud’s phenomenon that often appear before other manifestations.
Hormonal Factors: Scleroderma is more common in women than men, particularly during childbearing years, suggesting hormones may play a role. Some women report symptom onset or worsening during pregnancy or after childbirth, though the exact hormonal mechanisms remain unclear.
Frequently Asked Questions
What is scleroderma?
Scleroderma is a chronic autoimmune disease that causes hardening and tightening of the skin and connective tissues due to excessive collagen production. It can be localized, affecting only the skin, or systemic (systemic sclerosis), affecting internal organs including the heart, lungs, kidneys, and digestive system.
Is scleroderma the same as systemic sclerosis?
Yes, the terms are often used interchangeably. Systemic sclerosis is the medical term for the form of scleroderma that affects not only the skin but also internal organs. Scleroderma is the broader term that encompasses both localized forms (affecting only skin) and systemic forms.
Can scleroderma be cured?
Currently, there is no cure for scleroderma. However, various treatments can help manage symptoms, slow disease progression, and improve quality of life. Early diagnosis and appropriate management are important for the best outcomes.
How is scleroderma diagnosed?
Diagnosis involves a combination of physical examination, medical history, blood tests for specific antibodies, skin biopsy, and imaging studies. Your doctor may also perform tests to check organ function, including lung function tests, echocardiogram, and kidney function tests.
Who is most at risk for developing scleroderma?
Scleroderma most commonly affects women between ages 30 and 50, though it can occur in anyone at any age. Risk factors include being female, having a family history of autoimmune diseases, and certain environmental exposures, though most people who develop scleroderma have no identifiable risk factors.
Does everyone with Raynaud’s phenomenon develop scleroderma?
No. Raynaud’s phenomenon is common in the general population and most people with Raynaud’s never develop scleroderma or any other connective tissue disease. However, when Raynaud’s is severe, occurs at an older age, or is accompanied by other symptoms, it may be associated with scleroderma.
How quickly does scleroderma progress?
Disease progression varies significantly among individuals. Some people experience rapid changes within the first few years, while others have slowly progressive or stable disease. Diffuse scleroderma tends to progress more quickly initially than limited scleroderma, but may stabilize over time.
Should I see a doctor if I have these symptoms?
Yes, if you experience symptoms such as skin hardening, persistent Raynaud’s phenomenon, unexplained digestive problems, shortness of breath, or joint pain, you should consult a healthcare provider. Early evaluation is important for proper diagnosis and management. A rheumatologist specializes in diagnosing and treating scleroderma and other autoimmune conditions.
