Vitiligo FAQs

Answers to Frequently Asked Questions About Vitiligo

What is Vitiligo?

Vitiligo is an incurable skin illness characterized medically by white spots, known as macules, and microscopically by the absence of pigment-producing cells in the skin.

Who Can Get Vitiligo?

It has been reported that vitiligo affects 1% to 2% of the population, regardless of gender, ethnicity, or age. Because the affected and unaffected patches of skin are different, vitiligo stands out more in those with it.

Many nations like India have stigmatized vitiligo, limiting affected people’s chances of social advancement and marriage. In half of all cases, vitiligo begins between ages 10 and 30. There have been a few reports of the disease appearing at birth, while Vitiligo onset in older adults is quite rare. More than 30% of those affected report a family history.

It has been observed that identical twins can get vitiligo, though the risk to the offspring is unknown. Vitiligo is more common in people who come from families who have a history of thyroid disease, diabetes, and vitiligo.

What Causes Vitiligo?

The causes of vitiligo include both predisposing genetic factors and precipitating environmental factors. Many people attribute their vitiligo to physical trauma, illness, or emotional stress.

It is frequently claimed that onset occurs after the death of a relative or after major bodily harm. Vitiligo can also be triggered by a sunburn reaction.

Where Does Vitiligo Appear on the Body?

The appearance of white patches will depend on which type of vitiligo you have. They can be classified into three types based on the pattern of depigmentation.

The most common form of vitiligo is generalized vitiligo, which consists of widespread distribution of white macules that sometimes are arranged in a striking symmetrical pattern.

One or more macules in a single location describe focal vitiligo, and sometimes this represents an early stage in the development of one of the other forms of the disease. The fingers, elbows, knees, lower back, and genital area are all common sites for macules. 

In severe cases of generalized vitiligo, only a few pigmented macules are present, a condition known as vitiligo universalis

The segmental type of vitiligo appears on a hand or one side of the body. Vitiligo patches do not form, and vitiligo macules rarely accompany this type on other parts of the body with this type.

Why Does Vitiligo Develop?

Vitiligo is caused by a variety of reasons. Numerous explanations have been proposed, including autoimmune disease, the interaction between melanocytes and the nervous system, and toxic substances created by normal melanin production that are toxic to melanocytes. During the process, cytotoxic T-cell cells eliminate certain melanocytes over time.

How Much Vitiligo Will I Develop?

Vitiligo is a chronic condition. Its course is exceedingly diverse and unpredictable, although the most common pattern is a quick beginning followed by a period of stability or slow advancement. Up to 30% of vitiligo patients report spontaneous repigmentation, especially in sun-exposed areas, but this is virtually never enough to meet the patient’s needs.

Treatment for vitiligo-related diseases such as thyroid disease does not result in pigment recovery in affected areas.

Should I Take Vitamin D for my Vitiligo?

Vitamin D is essential for preventing a variety of inflammatory and chronic disorders. Most adults should consume 1,000–4,000 IU (25–100 mcg) of vitamin D3 daily to maintain optimal health. Vitamin D levels in patients with vitiligo should generally be kept in the mid-upper range of normal.

According to one study, high-dose vitamin D therapy may be both safe and beneficial in treating vitiligo. Sixteen patients with primarily darker skin types were given 35,000 IU of vitamin D per day for 6 months, along with a dairy and calcium-rich food limitation and minimum hydration of 2.5 L per day. At least 14 people experience positive repigmentation results ranging from 25% to 75%. It’s still uncertain whether patients with vitiligo benefit from long-term, high-dose supplementation.

What are the Dangers of Corticosteroid Medicines?

Vitiligo is frequently treated with corticosteroid medicines such as hydrocortisone and others. Corticosteroids inhibit the immune system and lessen the signs and symptoms of numerous illnesses by mimicking the effects of hormones produced naturally in the adrenal glands. However, these medications come with the potential of major adverse effects.

Oral corticosteroids (in the form of pills, capsules, or syrup) have a broad influence on your body and are the most likely to produce serious adverse effects:

  • Infections are more likely
  • Cataracts (clouding of the lens)
  • Glaucoma (elevated pressure in the eyes)
  • Retention of fluid (causing swelling in your legs and arms)
  • Fractures and bone thinning (osteoporosis)
  • Blood pressure that is too high
  • Sugar levels that are too high (a concern for people with diabetes)
  • Confusion or delirium, mood swings, and memory irregularities are among psychological impacts
  • Fatigue, loss of appetite, nausea, and physical weakness are all symptoms of this condition
  • Fat deposits in the abdomen, face, and back of the neck accompany weight growth

Topical corticosteroids can cause:

  • Infections are more likely
  • Acne
  • Insomnia
  • Facial flushing
  • Lesions on the skin that are red
  • Bruising and a delay in the healing of wounds

Consult your doctor about measures to minimize corticosteroid side effects to lessen your chance of them. Keep a healthy weight, strengthen bones and muscles, and improve your sleep by eating a nutritious diet and participating in activities that help you maintain a healthy weight, strengthen bones and muscles, and improve sleep.

What Diseases Commonly Occur Along With Vitiligo?

Vitiligo patients had a statistically significant greater prevalence of other autoimmune illnesses and dermatological problems, according to a recent study, including:

  • Lymphoma
  • Psoriasis
  • Alopecia Areata
  • Chronic Urticaria
  • Ulcerative Colitis
  • Celiac Disease
  • Raynaud’s Disease
  • Crohn’s Disease
  • Linear Morphea
  • Hypothyroidism
  • Multiple Sclerosis
  • Rheumatoid Arthritis
  • Addison’s Disease
  • Sjögren Syndrome
  • Seronegative Arthritis
  • Pernicious Anemia
  • Myasthenia Gravis
  • Dermatitis Herpetiformis
  • Type 1 & Type 2 Diabetes
  • Guillain-barre Syndrome
  • Inflammatory Bowel Disease
  • Systemic Lupus Erythematosus
  • Idiopathic Thrombocytopenic Purpura

Most vitiligo patients will not develop autoimmune illness, although a small percentage will develop hypothyroidism.

Patients and their caregivers should be aware of the disorders that can arise alongside vitiligo. If you have several diseases, it’s critical that your doctor be aware of any prescriptions and drugs you’re taking to ensure that they don’t interact.

Which Skin Diseases can be Confused for Vitiligo?

Vitiligo is a prevalent skin disorder characterized by irregularly shaped milky white patches. However, several other skin disorders have similar symptoms and might lead to a vitiligo misdiagnosis.

In addition, skin color loss can be induced by contact with substances that kill skin pigment cells. These are chemicals commonly found in the workplace, although they can also be present in some cosmetic items. Chemical or contact leukoderma is the name given to this skin disorder.

A well-trained dermatologist should be able to tell the difference between vitiligo and more than twenty other skin diseases.

Some Similar Skin Conditions & Differences from Vitiligo

  • Leprosy: a bacterial infection that causes light-colored patches on the skin and loss of sensation and hair above them. It is a curable disease that is rarely seen in the Western world.
  • White Scars: A scar from previous skin damage may leave a white patch after healing. It can resemble vitiligo at times, famously difficult to treat.
  • Tenia Versicolor (also known as Pityriasis versicolor) is a fungal illness that develops due to oily skin and poor personal hygiene, particularly in warm and humid environments. This illness frequently affects school-aged youngsters. It manifests itself as a white area with a fine dry, scaly skin surface on the cheeks, face, and neck.
  • Pityriasis Alba: a white patch on the face of youngsters is frequent during the winter months. Severe instances are uncommon and necessitate the care of a dermatologist. Boys, on average, are more affected than girls.
  • Piebaldism: a rare genetic condition defined by the lack of melanocytes from a section of the skin with a sharp, visible edge present at birth. A swarm of white hair frequently marks the forehead. This is a disease that is almost always fatal.
  • Chemical Leukoderma: a condition in which specific chemicals generate characteristic white spots on the skin that resemble vitiligo. This disorder is frequently self-reversible or can be successfully treated within a few months.
  • Halo Nevus: a type of mole that seems to be inside a depigmented circle. The specific cause of Halo nevus development is uncertain. It is frequently used as a warning sign of vitiligo and does not require treatment.

Idiopathic Guttate Hypomelanosis: multiple spherical, light-colored patches that occur on exposed body regions may resemble confetti-like vitiligo, but they aren’t it. People over the age of 40 are more likely to develop this illness than those in their early to mid-thirties.
