Reasons for Vitiligo

Vitiligo is common now in many people. They suffer from Vitiligo and major issue is that, there is no proven & confirmed medicine.

Vitiligo has become a widely recognized skin condition affecting a growing number of people globally. It causes pale pink or white patches on the skin, often triggering psychological as well as social discomfort in sufferers. One of the most frustrating aspects of vitiligo is the absence of a proven or permanent cure. While research is ongoing, science has yet to find a 100% effective treatment.

Let’s explore in-depth what vitiligo is, its major causes, symptoms, types, treatment options, and precautionary tips. This guide will help you understand the condition in a more comprehensive way.

What is this Vitiligo?

Vitiligo is the condition where white or pinkish patches develops on our skin.
Skin has one components called as MELANIN. It functions for skin pigmentation. If in case this system fails to work, then vitiligo (white patches) is the result. It may start appearing on any skin area of our body. Most probably it will be first noticeable on our face, neck and our hands.

Vitiligo is a chronic skin condition in which the skin loses its natural color in patches due to the destruction or malfunctioning of melanocytes — the cells responsible for producing melanin, the pigment that gives skin, hair, and eyes their color. When these melanocytes stop functioning or die, it leads to depigmented or white spots appearing on the skin.

These patches can develop on any part of the body, but are commonly seen first on sun-exposed areas such as the face, neck, hands, and arms. The patches can slowly grow in size, and later on spread to rest parts of the body. In some cases, hair growing in these areas may also turn white.

Although vitiligo is not life-threatening or contagious, it can cause emotional stress and affect an individual’s self-confidence, especially if the patches are visible and large.

 

What are the Major Reasons for Vitiligo?

There is still not the identified reason. Medical associations do not have confirmed data for exact causes.
On the basis of possibility, below are some reasons. It may be leading for Vitiligo.

 

1. Genetic Effects

Vitiligo is one disease and it is related to immunity. Due to loss of epidermal melanocytes, depigmentation of skin will be the result.
It is assumed that around 30% cases are genetic. Study is still in progress and going on about this for surety. But in fact if your family have a background of vitiligo, then it might have chances to other members.
In such rare cases, If a genetic mutation starts to targeting the cells, then it will lead your skin pigmentation.
In case if any changes in our DNA, then it will effect melanocytes functions. Hence genetics factor effects on vitiligo disorder.

While studies are still ongoing, several genes linked with immune system regulation, such as NLRP1, PTPN22, and HLA genes, have been associated with vitiligo. These genetic variations might cause the immune system to mistakenly attack healthy melanocytes, resulting in depigmentation.

 

2. Stress & Emotional Triggers

Stress is one of the big cause behind many diseases. In today’s modern, challenging & competitive life, we cannot avoid stress. If we fail to manage it, then the stressful atmosphere will bring many diseases for you.
Due to stress, there may be a change in pigmentation proportion of melanocyte cells. Hence stress can lead to vitiligo.

 

3. Misunderstanding of Immunity System

Some time our immunity system does mistakes to judge the friendly cells. It reacts against our healthy melanocytes cells. Our immunity system assumes that, these healthy cells are like harmful bacteria. Eventually such situations leads to develop antibodies for destroying melanocytes.
We cannot say anything when above situations will arise and what is the exact causes behind it.

Vitiligo is often categorized as an autoimmune disorder. In such a case, the immune system which is for defends the body from harmful invaders, mistakenly identifies healthy melanocytes as foreign bodies and destroys them.

This autoimmune reaction is thought to be the root cause in most non-segmental vitiligo cases. Individuals with other autoimmune diseases such as thyroid disorder, lupus, rheumatoid arthritis, or type 1 diabetes are more likely to develop vitiligo.

 

4. Atmospheric Changes

Exposure to the ultraviolet radiation, some types of chemical contacts, stress, products related to skin whitening can cause for Vitiligo, hence atmospheric or environmental is one of the reasons for vitiligo.

Exposure to certain chemicals, UV radiation, industrial solvents, and environmental toxins might trigger vitiligo in genetically susceptible individuals.

Occupational exposure to phenol-containing compounds, found in hair dyes, rubber products, and adhesives, can be harmful to melanocytes. Similarly, excessive use of skin-whitening products, sunburn, and pollution are believed to disturb melanin production.

 

What are the Common Symptoms of Vitiligo?

Any person can get affected at any time. Reasons may vary from person to person. Some of them have been mentioned above. You may get its anticipation if notice related symptoms.
Vitiligo usually gets noticed with small white patch on any part of your body. It will gradually increase the affected area. Colour may be white or pinkish. Generally these patches will not give you pain or any trouble, but in some cases it may be itchy.
Some people may suffer small patches whereas some may suffer from big one. It cannot be predicted that how much patches would be in size. But mostly such patches are permanent.

Summary:

• White or light pink patches on the skin
• Skin color loss in mucous membranes (inside nose and mouth)
• Premature whitening or graying of scalp hair, eyebrows, eyelashes, or beard
• Depigmented patches around body openings like eyes, nostrils, and genitals
• In some rare cases, discoloration to the retina, or even inner eye layer

 

What are the Main Types of Vitiligo?

We can categorize vitiligo in two segments.

• Segmental vitiligo
• Non-segmental vitiligo

Segmental Vitiligo :

This is also called as universal or localised vitiligo. In this case, our one side body gets affected by vitiligo.

Patches appears on one of the side of your body, like on hands or face etc.

• Affects only one part or segment of the body (like one arm or one side of the face)
• Commonly appears at a younger age
• Progresses for 6–12 months and then stabilizes
• Less associated with autoimmune diseases

 

Non-Segmental Vitiligo :

This is also called as generalized or bilateral vitiligo.
It affects some of the parts of body, like hand, feet, elbow etc.
This one is most common type. If we calculate frequency, then can say around 9 people out of 10 comes in this category.

• This Also known as generalized or bilateral vitiligo
• Appears on both sides of the body in a symmetrical pattern
• Commonly affects hands, feet, elbows, knees, and face
• Progresses unpredictably over time
• Associated with other autoimmune disorders

This type accounts for nearly 90% of vitiligo cases worldwide.

 

Some other Types of Vitiligo

• Universal: This comes in rare category and covers more than 80% of body parts. A rare type where more than 80% of the skin loses pigmentation. Often starts as non-segmental vitiligo and progresses rapidly

 

• Focal: Patches develops in small area and does not spread in the certain pattern within span of one to two years. Localized form where a few spots appear and don’t spread within 1–2 years. Common among children and young adults.

 

• Generalized: Here patches appears on various parts of body. In this case, there is no sufficient working melanocytes.  It is needed to generate melanin in enough proportion that requires to our skin. Eventually results in white patches on skin.

 

• Trichome: In this case patches are like a bulls eye. Here is an intermediate zone of hypopigmentation, that will be at the place between our unaffected or normal skin & depigmentation center. Depigmented patch has three zones: normal skin color, a lighter intermediate zone, and a completely white center. Resembles a bullseye appearance.

 

• Mucosal: Mucous membranes of mouth as well as genitals gets affected in Mucosal vitiligo. Affects mucous membranes such as the lips, gums, inner cheeks, and genital areas. Can be painful in some cases

 

What is the Treatment for Vitiligo?

No treatment is necessary for vitiligo & it is not harming body rather than depigmentation. Patches are permanent and treatment can reduce somewhat appearance of patches. Vitiligo cannot be treated completely but this is attempt for somewhat appearance correction.
If you still want somewhat uniformity in skin by either color restoration or depigmenting of the remaining color, then you can find the help of doctor.

 

Below are some of the treatments for getting relief in Vitiligo:

1. Phototherapy

It is also called as light therapy. This system uses ultra violet light. We can say it is just like similar to natural sunlight.
Focusing such ultraviolet rays on affected area, attempts are done to prevent the patches further extension. It is a painless therapy and takes around 10 to 15 minutes for entire body.
Phototherapy requires many visits and longer time periods to get result. It means several months or years, still patient can disappoint by the result. Three is no any such surety.

This involves exposing the skin to narrowband ultraviolet B (NB-UVB) light under medical supervision. It stimulates melanocyte activity and then helps repigment to the affected areas.

• Requires 2–3 sessions per week for several months
• May help stabilize the immune response
• Not suitable for all skin types or children

 

2. Steroid Cream

Steroid or other chemicals added creams, might help in a smaller pigmentation. Frequent use of such creams is also harmful to skin.

Steroid-based creams (e.g., corticosteroids) can help return some color to the skin, especially in the early stages. However, long-term use may cause thinning of the skin and other side effects.

 

3. Surgery

Skin grafting and melanocyte transplantation are surgical techniques that may help in small, stable vitiligo areas. They are expensive and not commonly used due to risk of scarring.

 

4. Depigmentation therapy

If vitiligo has affected more than 50% of the body, some people choose to lighten the remaining pigmented skin to match the white patches. This is done using monobenzone or other skin-lightening agents.

• Permanent and irreversible
• Increases sun sensitivity

 

5. Laser treatment

Excimer lasers may help target small patches by stimulating melanocyte growth in localized areas. This method is generally used for face and neck patches.

 

6. Chemical solutions etc.

Mild chemical peels or herbal ointments are used in some traditional systems of medicine (Ayurveda, Unani), but lack scientific validation. Consultation with a qualified practitioner is essential.

 

What are the Complications of vitiligo?

Vitiligo can sometimes cause other problems.
Vitiligo results in heavy decrease in melanin. This situations will easily harm the skin if we stay for some time in sunlight. Proper covering the upper skin by clothes, using umbrella or good sunscreen can give relief.

Vitiligo may also lead to adverse effects on eyesight and even hearing capacity.

• Increased sun sensitivity due to reduced melanin
• Psychological impact including depression, anxiety, and self-esteem issues
• Hearing loss in rare cases, as melanocytes are also found in the inner ear
• Eye problems like inflammation in the iris or retina

 

Which people have more possibilities for vitiligo?

If you comes in below categories then, you are more prone for vitiligo.

• Diabetes
• Thyroid
• Lupus
• Rheumatoid arthritis
• Psoriasis
• Family History
• Chemical Exposure
• Sunburn History
• Skin Trauma or Chronic Stress

 

What are bad effects or complications of Vitiligo?

Yes, vitiligo can significantly affect emotional and social well-being, especially in visible areas like the face or hands. Many people experience:

1. Effects on Vision

Normally vision does not get affect, but there are some other discrepancies.
Retina the inner sensitive layer of eye might get inflammation.

 

2. Depression

This is a very big challenge to overcome. Some people find very difficult to adjust and mix with other people. This situations can invite for depression.

• Feelings of isolation or embarrassment
• Difficulty in social interactions
• Emotional stress from lack of cure

 

3. Sunburn

Sunburn is more harmful for the vitiligo affected person’s skin. Hence need to take proper care while roaming in sunlight. Skin becomes more sensitive in vitiligo.

The skin with vitiligo lacks natural protection from UV rays. Even short sun exposure may cause for sunburn, with increasing the risk of skin damage. Use SPF 50+ sunscreen, wear full-sleeve clothes, and avoid direct sun exposure during peak hours.

 

Frequently Asked Questions:

Is this Vitiligo Painful or any health troubles?
Vitiligo will not give you pain or aching. However you need to take sufficient precautions in sun light, otherwise you will be the very easy target for Sunburn.

However, emotional discomfort and sunburn are common issues.

 

What are the percentage of vitiligo on affecting worldwide?

About 0.5% to 2% population of the world suffers from vitiligo. It affects all genders, races, and ages equally.

 

Final Thoughts:

Such pale skin area is more easy target for Sunburn. So need to take extra care. Use sunscreen creams, cover your body by cloths, use umbrella etc. and save your self from Sunburn. Above mentioned are some of the Reasons for vitiligo, so better to avoid those incidents. There is no confirmed treatment to deal with vitiligo.

Vitiligo is a complex skin condition influenced by multiple factors, including genetics, immunity, stress, and environmental triggers. While it is not physically harmful, it can be emotionally distressing.

Timely medical consultation, lifestyle changes, stress management, and consistent sun protection can go a long way in managing the condition. Public awareness and social support are also essential to reduce stigma and improve the quality of life for those affected.
