Fabry disease awareness

Overview

Fabry disease is a rare, inherited condition where the body cannot break down certain fats properly. This causes fats to build up in cells and can lead to problems in the heart, kidneys, brain, and skin.

No, Fabry disease is rare. It affect about 1 in every 40,000 to 60,000 people, though many cases may go unrecognized.

Fabry disease can affect both males and females, and all ethnic groups. Males often have more severe symptoms, while females can have mild to severe symptoms as well. It can appear in childhood or only become noticeable in adulthood.

Symptoms

Common symptoms

• Burning or tingling pain in the hands and feet, especially during fevers or exercise
• Small, dark red or purple spots on the skin, often between the belly and knees
• Reduced sweating or trouble sweating, leading to overheating
• Stomach pain, diarrhea, or nausea after eating
• Cloudy or hazy vision
• Hearing loss or ringing in the ears
• Fatigue and low energy

Symptoms in children

• Pain in the fingers and toes that may be worse in hot weather or with fever
• Skin spots that may appear before other symptoms
• Stomach cramps and bowel issues
• Trouble keeping up with physical activity due to fatigue

Symptoms in older adults

• Kidney problems, including protein in the urine or reduced kidney function
• Heart issues such as an enlarged heart, irregular heartbeat, or heart failure
• Strokes or mini-strokes
• Chronic pain and digestive problems

Causes

Main causes

• A change (mutation) in a gene called GLA that gives the body instructions to make an enzyme called alpha-galactosidase A.
• Without enough working enzyme, certain fats called globotriaosylceramide build up in cells and cause damage over time.

Risk factors

• Having a parent with Fabry disease (it is inherited in an X-linked pattern, so mothers can pass it to sons and daughters, and fathers can pass it to daughters).
• Having a sibling or other close relative with the condition.
• Being of any ethnic background — Fabry disease occurs across all populations.

When to see a doctor

See a doctor urgently if:

• Seek same-day medical care if you have swelling in your legs, blood in your urine, unmanageable pain, or repeated vomiting.
• If you have any symptoms of a stroke or heart attack, call your local emergency number immediately.

Book a routine appointment if:

• If you or your child have unexplained burning pain in the hands or feet, skin spots, digestive issues, or kidney problems, talk to your healthcare provider.
• If you have a family history of Fabry disease, ask about genetic testing even if you feel well.

Diagnosis

A doctor will review your symptoms, your family history, and do a physical exam. If Fabry disease is suspected, blood and genetic tests are needed to confirm it.

Tests that may be done

• Blood test to measure the activity of the alpha-galactosidase A enzyme (often used in males).
• Genetic testing to look for changes in the GLA gene (used to confirm in both males and females).
• Urine tests to check for kidney damage.
• Sweat tests or eye exams, if other related issues are noted.

What to expect at your appointment

Diagnosis is often made by a specialist such as a geneticist, kidney doctor, or heart doctor. You may need several appointments and a referral to a multidisciplinary team that includes specialists in genetics, kidney care, heart care, neurology, and pain management.

Treatment

There is no cure for Fabry disease, but treatment focuses on replacing or improving the missing enzyme, managing symptoms, protecting organs, and improving quality of life. With the right treatment plan, many complications can be prevented or delayed.

Self-care at home

• Drink plenty of water to stay well-hydrated.
• Avoid very hot or very cold temperatures to reduce pain and sweating problems.
• Wear supportive shoes and loose clothing to ease foot and leg discomfort.
• Keep a diary of symptoms to discuss with your healthcare team.
• Rest when you need to and pace your daily activities.

Medical treatments

Medical treatment may include enzyme replacement therapy, which supplies the body with a working version of the enzyme through regular IV infusions. Other therapies can help the enzyme work more effectively. Pain relievers, stomach medications, and treatments for high blood pressure, kidney issues, or heart problems may also be prescribed. Your specialist team will adjust your treatment based on your needs.

When is surgery considered?

Surgery is not a routine part of Fabry disease treatment. However, if kidney failure develops, dialysis or a kidney transplant may be necessary. Heart problems may also require procedures, such as surgery or implants, depending on the individual case.

Living with this condition

Living with Fabry disease means managing symptoms and staying on top of regular check-ups. Work closely with your healthcare team, take medications as prescribed, and let your family and friends know how they can support you.

Lifestyle tips

• Stay physically active in ways that feel good for you, but avoid pushing through severe pain.
• Protect your skin from extreme heat and direct sun exposure.
• Avoid smoking and limit alcohol, as these can harm your heart and kidneys.
• Join a support group or connect with others living with Fabry disease.

Diet and exercise

A balanced diet helps protect your heart and kidneys. Work with a dietitian if you have kidney issues. Gentle exercise like walking, swimming, or yoga can improve energy and pain, but always stop if you feel unwell and talk to your doctor about what is safe for you.

Mental health and emotional wellbeing

Coping with a chronic condition can bring anxiety, sadness, or frustration. These feelings are understandable and deserve attention. Talk openly with a counselor, psychologist, or your care team. If you ever have thoughts of harming yourself, call your local emergency number or a crisis support line right away – you are not alone, and help is available.

Prevention

Fabry disease is genetic, so it cannot be prevented. If you have a family history, genetic counseling can help you understand risks for yourself and your children.

Vaccines

Stay up to date with recommended vaccines, especially for flu and pneumonia, to avoid infections that could stress your heart, kidneys, or immune system.

Screening programmes

Family members of a person diagnosed with Fabry disease may be offered screening (blood and genetic tests) to detect the condition early, even before symptoms appear.

Complications

If left untreated

• Kidney damage leading to kidney failure and the need for dialysis or transplant
• Heart disease, including an enlarged heart, irregular heartbeat, and heart failure
• Strokes or small holes in brain tissue from reduced blood flow
• Chronic pain, digestive problems, and fatigue that affect daily life

Long-term outlook

With early diagnosis and proper care, many people with Fabry disease live full and active lives. Treatments can slow or prevent major complications, and ongoing research continues to improve outcomes. Your future is not defined by the condition alone – it is shaped by the care you receive and the support you have.
