Vitiligo and Diet: What to Avoid

If you or someone you know suffers from vitiligo, then you understand how traumatic, difficult to treat, and embarrassing this skin condition can be. It’s characterized by white irregular patches on different parts of the body. The most commonly affected areas include hands, face, neck, armpits, and legs. This disorder occurs when melanin-producing cells, melanocytes, are destroyed.

Vitiligo is a disorder in which melanocytes, the cells that make pigment in the skin, the mucous membranes and the retina of the eye are destroyed, leading to the development of white patches on the skin. Vitiligo is thought to develop in about 0.1% to 2% of various populations, affecting 2–5 million people in the United States and 40–50 million people worldwide. It’s cause remains unknown although it has been established that it is an autoimmune disease.
Diet plays an important role in the treatment of Vitiligo. Cold and phlegm producing foods are harmful in this disease. Lesions can spread if such foods are eaten frequently. Only whole grain breads are recommended and processed grain is not to be taken. A lot of ginger and turmeric should be used in the food since they are natural anti septic and it is better if the diet is salt free.
A lot of nuts should be also taken as they are rich in vitamin E and special fats.
Foods to Avoid
Spices and Artificial Food Colors

Excessively Sour Foods
Fruits like lemons, limes and others that are excessively sour can make this disorder worse. Besides, they contain ascorbic acid which lightens the skin, so eating them might worsen your vitiligo.
Non-vegetable Foods

Lastly, cut down on non-vegetable foods like fish, red meat, dairy products and all the high-calorie fatty and sugary foods. Why? Because some bodies misread them as foreign bodies and fight them, causing adverse reactions including vitiligo.

Treatment Help for Vitiligo

Vitiligo affects up to 2% of the population, and it is estimated that two to five million Americans have the condition. In most cases, vitiligo develops early in life, between the ages of 10 and 30 years. Ninety-five percent of those affected will develop the disorder before age 40. Both men and women are equally likely to develop vitiligo. Vitiligo may run in families; those with a family history of vitiligo or premature graying of the hair are at increased risk for the development of vitiligo. Other risk factors that increase one's chances of developing vitiligo include having autoimmune diseases, such as autoimmune thyroid disease (Hashimoto's thyroiditis).

Vitiligo is difficult to treat. Early treatment options include the following:Phototherapy, a medical procedure in which your skin is carefully exposed to ultraviolet light. Phototherapy may be given alone, or after you take a drug that makes your skin sensitive to light. A dermatologist performs this treatment.
Certain lasers may help the skin repigment.

Phototherapy Treatment for Vitiligo - Best Vitiligo Hospital

Vitiligo is a chronic condition that causes pale, white patches to develop on the skin. The areas affected have little or no melanin.
Melanin is a dye-like substance that is produced by specialised skin cells called melanocytes, which give your skin its colour and protect it from the sun's rays.

Where does vitiligo occur?
Vitiligo can affect any area of your skin, but most commonly occurs on skin that is exposed to the sun, such as your face, neck and hands.
Vitiligo is more noticeable in people whose skin is dark or tanned. The condition varies from person to person. For example, some people only get a few small, white patches that progress no further. Other people get bigger white patches that join up across large areas of their skin.

There is no way of predicting how much of your skin will be affected, and the white patches are usually permanent.
Phototherapy (treatment with light) may be used for children or adults if:
topical treatments haven't worked
the vitiligo is widespread
the vitiligo is having a significant impact on quality of life
Evidence suggests that phototherapy, particularly when combined with other treatments, has a positive effect on vitiligo.
During phototherapy, your skin is exposed to ultraviolet A (UVA) or ultraviolet B (UVB) light from a special lamp. You may first take a medicine called psoralen, which makes your skin more sensitive to the light. Psoralen can be taken by mouth (orally), or it can be added to your bath water.
This type of treatment is sometimes called PUVA (psoralen and UVA light).
Phototherapy may increase the risk of skin cancer because of the extra exposure to UVA rays. The risk of skin cancer is lower with UVB light. Your dermatologist should discuss the risk with you before you decide to have phototherapy.

Sunlamps that you can buy to use at home for light therapy aren't recommended. They're not as effective as the phototherapy you'll receive in hospital. The lamps are also not regulated, so may not be safe.
