Scleroderma symptoms vary, depending on which organ systems are involved. Diagnosis can be difficult because some of the early symptoms are common in the general population and aren't always associated with scleroderma. The most prevalent signs and symptoms of scleroderma include:

• Raynaud's phenomenon. An exaggerated response to cold temperatures or emotional distress, this condition constricts the small blood vessels in the hands and feet and causes numbness, pain or color changes in the fingers or toes.
• Gastroesophageal reflux disease (GERD). In addition to acid reflux, which can damage the section of esophagus nearest your stomach, you may also have problems absorbing nutrients if your intestinal muscles aren't moving food properly through your intestines.
• Skin changes. These changes may include swollen fingers and hands; thickened patches of skin, particularly on the fingers; and tight skin around the hands, face or mouth. Skin can appear shiny because it's so tight, and movement of the affected area may be restricted.

Localized scleroderma
The two main varieties of localized scleroderma, which affects only the skin, are distinguished by very distinctive signs and symptoms:

• Morphea. This variety features oval-shaped thickened patches of skin that are white in the middle, with a purple border. Skin patches could appear in only a few spots on your body or be more widespread, appearing all over your body. Morphea generally fades out after three to five years, but you may retain areas of darkened skin where the areas of thickened skin appeared.
• Linear scleroderma. This variety, which is more common in children, features bands or streaks of hardened skin on one or both arms or legs, or on the forehead. Linear scleroderma often appears mostly on one side of the body.

With localized scleroderma, the first signs of disease may be the presence of Raynaud's phenomenon and may develop several years before you notice any other symptoms.

Systemic scleroderma
This type of scleroderma, also called systemic sclerosis, affects not only your skin but also your blood vessels and internal organs. Subcategories are defined by what portions of your body are affected. One variation is known as limited scleroderma, or CREST syndrome.

With systemic scleroderma, skin changes may occur suddenly and progressively worsen during the first one to two years of the disease. After that, changes level off or subside, and sometimes even resolve on their own without treatment.

Scleroderma results from an overproduction and accumulation of collagen in body tissues. Collagen is a fibrous type of protein that makes up your body's connective tissues, including your skin.

Although doctors aren't sure what prompts this abnormal collagen production, the body's immune system appears to play a role. For unknown reasons, the immune system turns against the body, producing inflammation and the overproduction of collagen.

Several factors appear to increase the risk of certain types of scleroderma:

Race and ethnicity
Certain groups of people are more likely to develop scleroderma than are others:

• Native Americans. Choctaw Native Americans in Oklahoma are at least 20 times as likely as is the general population to develop systemic scleroderma. Oddly enough, this increased risk doesn't apply to Choctaws living in Mississippi.
• African-Americans. Systemic scleroderma is more common in African-Americans than it is in Americans of European descent. And the African-Americans who have systemic scleroderma are more likely to develop severe lung complications.

Gender
Scleroderma occurs at least four times as often in women as it does in men.

Environmental factors
Exposure to a variety of substances may be linked to the development of scleroderma. Examples include:

• Silica dust, which is common in coal mines and rock quarries
• Some industrial solvents, such as paint thinners
• Certain chemotherapy drugs

Scleroderma complications range from mild to severe. Some may even become life-threatening.

Circulatory complications
The variety of Raynaud's phenomenon that occurs with scleroderma can be so severe that the restricted blood flow permanently damages the tissue at the fingertips, causing pits or skin sores (ulcers). In some cases, gangrene and amputation may follow.

Lung complications
Scarring of lung tissue (pulmonary fibrosis) can result in reduced lung function, reduced ability to breathe and reduced tolerance for exercise. You may also develop high blood pressure in the arteries to your lungs (pulmonary hypertension).

Kidney complications
When scleroderma affects your kidneys, you can develop an elevated blood pressure and an increased level of protein in your urine. More serious effects of kidney complications may include renal crisis, which involves a sudden increase in blood pressure and rapid kidney failure.

Heart complications
Scarring of heart tissue increases your risk of abnormal heartbeats (arrhythmias) and congestive heart failure, and can cause inflammation of the membranous sac surrounding your heart (pericarditis).

Dental complications
Severe tightening of facial skin can cause your mouth to become smaller and narrower, which may make it hard to brush your teeth or to even have them professionally cleaned. People who have scleroderma often don't produce normal amounts of saliva, so the risk of decay increases even more. In addition, acid reflux can destroy tooth enamel, and changes in gum tissue may cause your teeth to become loose or even fall out.

Digestive complications
Scleroderma can affect your upper and lower digestive tracts. Digestive problems associated with scleroderma can lead to acid reflux and difficulty swallowing — some describe feeling as if food gets stuck midway down the esophagus — as well as bouts of constipation alternating with episodes of diarrhea.

Sexual complications
Men who have scleroderma often experience erectile dysfunction. Scleroderma may also affect the sexual function of women, by decreasing sexual lubrication and constricting the vaginal opening.

You'll probably first bring your symptoms to the attention of your family doctor, who may refer you to a rheumatologist — a doctor specializing in the treatment of arthritis and other diseases of the joints, muscles and bone. Because scleroderma can affect many organ systems, you may need to see a variety of medical specialists.

What you can do
Appointments can be brief. To make the best use of the limited time, plan ahead and write lists of important information, including:

• Detailed descriptions of all your symptoms
• A list of all your medications and dosages, including nonprescription drugs and supplements
• Questions for the doctor, such as what tests or treatments he or she may recommend

What to expect from your doctor
Your doctor will review your medical history and conduct a physical examination, which may include:

• Checking your skin for thickened and hardened areas
• Feeling some of your joints and tendons to check for possible changes in connective tissue beneath your skin
• Inspecting your fingers for changes that may indicate Raynaud's disease

Your doctor may conduct the following tests:

• Blood tests. People with scleroderma usually have elevated blood levels of certain antibodies produced by the immune system.
• Tissue sample. Your doctor may remove a small tissue sample (biopsy) of your affected skin to be examined in the laboratory for abnormalities.
• Skin assessment. Your doctor ideally evaluates the condition of your skin in 17 specific areas to determine the level of skin involvement, which provides a clue to the likelihood that you also have life-threatening changes happening to internal organs.

Based on the outcome of your initial evaluation, your doctor may also recommend other diagnostic tests to identify any lung, heart, kidney or gastrointestinal complications accompanying scleroderma.

Scleroderma has no known cure — no drug will stop the overproduction of collagen. But the localized variety of scleroderma sometimes resolves on its own. And a variety of medications can help control the symptoms of scleroderma or help prevent complications.

Medications

• Dilating the blood vessels. Blood pressure medications that dilate blood vessels may help prevent lung and kidney problems and may help treat Raynaud's disease.
• Suppressing the immune system. Drugs that suppress the immune system, such as those taken after organ transplants, may help reduce scleroderma symptoms.

Therapy

• Physical or occupational therapy. Therapists can help you to manage pain, improve your strength and mobility, and work on performing essential daily tasks to maintain your independence.
• Cosmetic procedures. The appearance of skin lesions associated with scleroderma may be helped by exposure to ultraviolet light. Laser surgery also may help camouflage or eliminate these lesions.

Surgery

• Amputation. If finger ulcers caused by severe Raynaud's disease have developed gangrene, amputation may be necessary.
• Lung transplants. People who have developed high blood pressure in the arteries to their lungs (pulmonary hypertension) may be candidates for lung transplants.

You can take a number of steps to help manage your symptoms of scleroderma:

• Stay active. Exercise keeps your body flexible, improves circulation and relieves stiffness. Range-of-motion exercises can help keep your skin and joints flexible.
• Don't smoke. Nicotine causes blood vessels to contract, making Raynaud's phenomenon worse. Smoking can also cause permanent narrowing of your blood vessels. Quitting smoking is difficult — ask your doctor for help.
• Manage heartburn. Avoid foods that give you heartburn or gas. Also avoid late-night meals. Elevate the head of your bed to keep stomach acid from backing up into your esophagus (reflux) as you sleep. Antacids may help relieve symptoms.
• Protect yourself from the cold. Wear warm mittens for protection anytime your hands are exposed to cold — even when you reach into a freezer. When you're outside in the cold, cover your face and head and wear layers of warm clothing.

As is true with other chronic diseases, living with scleroderma can place you on a roller coaster of emotions. Here are some suggestions to help you even out the ups and downs:

• Maintain normal daily activities as best you can.
• Pace yourself and be sure to get the rest that you need.
• Stay connected with friends and family.
• Continue to pursue hobbies that you enjoy and are able to do.

If scleroderma makes it difficult for you to do things you enjoy, ask your doctor about ways to get around the obstacles.

Keep in mind that your physical health can have a direct impact on your mental health. Denial, anger and frustration are common with chronic illnesses.

At times, you may need additional tools to deal with your emotions. Professionals, such as therapists or behavior psychologists, may be able to help you put things in perspective. They can also help you develop coping skills, including relaxation techniques.

Joining a support group, where you can share experiences and feelings with other people, is often a good approach. Ask your doctor what support groups are available in your community.
