Skin Hardening? Why Scleroderma Occurs and Medically Approved Next Steps

Skin hardening can be caused by scleroderma, an autoimmune condition in which excess collagen and blood vessel changes tighten and thicken the skin and sometimes affect internal organs.

There are several factors to consider; medically approved next steps include prompt evaluation by a primary care clinician or rheumatologist with specific blood tests and organ screening, followed by individualized treatments like immune-suppressing medicines, therapies for Raynaud’s, blood pressure control, lung-directed options, physical therapy, and targeted lifestyle changes. See the complete guidance below for urgent warning signs and details that can shape your care plan.

Skin Hardening? Why Scleroderma Occurs and Medically Approved Next Steps

If you've noticed your skin becoming unusually tight, thick, or hard, it's natural to feel concerned. One possible cause is scleroderma, a rare but serious autoimmune disease. Understanding what scleroderma is, why it happens, and what to do next can help you take informed, confident steps toward proper care.

This guide explains scleroderma in clear, practical terms—without unnecessary alarm, but without minimizing its seriousness either.


What Is Scleroderma?

Scleroderma is a chronic autoimmune condition that causes the body to produce too much collagen. Collagen is a protein that gives structure to skin and connective tissue. In scleroderma, excess collagen builds up, leading to:

  • Thickened or hardened skin
  • Tightness or reduced flexibility
  • In some cases, damage to internal organs

The word "scleroderma" literally means "hard skin," but the condition can affect more than just the skin.

There are two main categories:

1. Localized Scleroderma

  • Affects only the skin and sometimes underlying tissues
  • Does not typically involve internal organs
  • Often milder but may still require treatment

2. Systemic Sclerosis (Systemic Scleroderma)

  • Affects the skin and internal organs
  • Can involve the lungs, heart, kidneys, digestive tract, and blood vessels
  • Requires close medical monitoring

Why Does Scleroderma Occur?

The exact cause of scleroderma is not fully understood. However, medical research shows it involves three main processes:

1. Immune System Dysfunction

Scleroderma is an autoimmune disease. This means the immune system mistakenly attacks the body's own tissues. That immune activity triggers inflammation and collagen overproduction.

2. Excess Collagen Production

Fibroblasts (cells that make collagen) become overactive. Too much collagen causes:

  • Skin thickening
  • Organ stiffness
  • Reduced flexibility in affected tissues

3. Blood Vessel Abnormalities

Small blood vessels can narrow or become damaged. This contributes to:

  • Poor circulation
  • Cold sensitivity
  • Delayed healing

Who Is at Risk for Scleroderma?

Scleroderma is rare, but certain factors increase risk:

  • Women (especially ages 30–50)
  • Family history of autoimmune disease
  • Exposure to certain environmental triggers (such as silica dust, though this is uncommon)

It's important to note: Most people with these risk factors never develop scleroderma.


Common Symptoms of Scleroderma

Symptoms vary depending on the type and severity. Early detection is important.

Skin Symptoms

  • Tight, shiny, or thickened skin
  • Hard patches
  • Swelling in hands or fingers
  • Reduced flexibility
  • Changes in skin color

Raynaud's Phenomenon (Often an Early Sign)

  • Fingers or toes turn white or blue in cold or stress
  • Numbness or tingling
  • Pain when circulation returns

Digestive Symptoms

  • Acid reflux
  • Trouble swallowing
  • Bloating
  • Constipation or diarrhea

Lung or Heart Symptoms (Systemic Cases)

  • Shortness of breath
  • Persistent cough
  • Chest discomfort
  • Fatigue

Kidney Complications (Rare but Serious)

  • Sudden high blood pressure
  • Headaches
  • Vision changes

If you're noticing skin changes or other concerning symptoms, Ubie's free AI-powered Scleroderma symptom checker can help you assess whether your symptoms align with this condition and guide your next steps toward proper medical care.


Is Scleroderma Dangerous?

Scleroderma can be mild or severe. Some people experience only limited skin involvement. Others develop complications affecting major organs.

Potential serious complications include:

  • Pulmonary hypertension
  • Interstitial lung disease
  • Kidney crisis
  • Heart rhythm abnormalities

The key point: Early diagnosis significantly improves outcomes.

Modern treatment has greatly improved survival and quality of life compared to decades ago.


How Is Scleroderma Diagnosed?

There is no single test that confirms scleroderma. Doctors use a combination of:

Medical History

  • Skin changes
  • Raynaud's symptoms
  • Digestive or breathing issues

Physical Examination

  • Skin thickening patterns
  • Nailfold capillary changes

Blood Tests

  • Autoantibodies (such as ANA, anti-centromere, anti-Scl-70)

Imaging or Organ Testing (if systemic disease is suspected)

  • Pulmonary function tests
  • CT scans of the lungs
  • Echocardiogram
  • Kidney function tests

Because scleroderma can affect multiple systems, patients are often referred to a rheumatologist (a specialist in autoimmune diseases).


Medically Approved Treatment Options for Scleroderma

There is currently no cure for scleroderma. However, treatments can:

  • Slow progression
  • Manage symptoms
  • Protect organs
  • Improve quality of life

Treatment is individualized based on which organs are involved.

1. Immune-Suppressing Medications

These help reduce inflammation and slow tissue damage:

  • Methotrexate
  • Mycophenolate mofetil
  • Cyclophosphamide (in severe cases)

2. Medications for Raynaud's

  • Calcium channel blockers
  • Vasodilators
  • Medications that improve blood flow

3. Lung-Specific Treatments

  • Antifibrotic medications
  • Pulmonary hypertension treatments

4. Blood Pressure Control (Critical for Kidney Protection)

  • ACE inhibitors are often used

5. Gastrointestinal Treatments

  • Acid-reducing medications
  • Pro-motility agents

6. Physical and Occupational Therapy

  • Maintain joint mobility
  • Prevent contractures
  • Improve hand function

Lifestyle Steps That Support Treatment

Medical therapy is central—but lifestyle adjustments matter too.

Protect Your Circulation

  • Keep hands and feet warm
  • Avoid smoking
  • Manage stress

Support Skin Health

  • Use fragrance-free moisturizers
  • Protect from cold and trauma

Maintain Lung Health

  • Avoid smoking and secondhand smoke
  • Stay current on vaccinations (flu, pneumonia, COVID-19 if advised)

Manage Acid Reflux

  • Eat smaller meals
  • Avoid late-night eating
  • Elevate the head of your bed

Stay Active

Regular, gentle exercise helps:

  • Maintain flexibility
  • Support circulation
  • Reduce stiffness

When to Seek Immediate Medical Care

While many symptoms develop gradually, seek urgent care if you experience:

  • Sudden severe headache with high blood pressure
  • New chest pain
  • Sudden shortness of breath
  • Rapid swelling or sharp decline in kidney function

These could signal serious complications and require prompt treatment.


Emotional Impact of Scleroderma

Chronic illness can affect mental health. It's common to feel:

  • Frustration
  • Fear about progression
  • Concern about appearance

Support groups, therapy, and patient communities can make a meaningful difference.

Remember: many people with scleroderma live full, productive lives with proper management.


The Importance of Early Action

If you notice:

  • Persistent skin thickening
  • Raynaud's symptoms
  • Unexplained digestive issues with skin changes

Don't ignore them.

Taking a few minutes to use a free Scleroderma symptom assessment tool can help you understand whether your symptoms warrant immediate medical attention and prepare you for a more productive conversation with your doctor.


Final Thoughts

Scleroderma is a complex autoimmune disease that causes excess collagen production, leading to skin hardening and sometimes organ involvement. While it can be serious, medical advances have significantly improved outcomes.

The most important steps are:

  • Pay attention to early skin or circulation changes
  • Seek medical evaluation
  • Follow through with recommended testing
  • Work closely with a rheumatologist
  • Speak to a doctor immediately about any symptoms that could be life threatening or serious

Knowledge reduces uncertainty. Action improves outcomes. If you're concerned, start by gathering information—and then speak to a qualified healthcare professional to protect your health.
