Manifestations: When immunity is low, melanocytes are vulnerable to attacks. You may notice that the edges of white patches become blurred and their areas expand, or small white spots appear on new areas such as the arms and neck. Some patients may also experience redness and mild itching at the patch sites, which is a sign that immune system disorders are irritating the skin. Without timely intervention, the spread of patches may accelerate.

Have you noticed that the white patches on your body are getting larger? This may be caused by the following factors:

1.Abnormally Active White Patches in Vitiligo Patients

Manifestations: When immunity is low, melanocytes are vulnerable to attacks. You may notice that the edges of white patches become blurred and their areas expand, or small white spots appear on new areas such as the arms and neck. Some patients may also experience redness and mild itching at the patch sites, which is a sign that immune system disorders are irritating the skin. Without timely intervention, the spread of patches may accelerate.

Causes: Immune system disorders lead to an increase in "inflammatory factors" in the body. These factors directly inhibit the ability of melanocytes to produce melanin, and also damage the normal skin barrier around the white patches, allowing the patches to "spread outward".

2.Recurrent Dryness and Sensitivity of the Skin

Manifestations: A decline in immunity impairs the skin’s barrier function. Even with proper moisturization, you may frequently experience skin peeling and tightness, or redness and rashes after contact with ordinary clothing or skincare products. This dryness and sensitivity are more pronounced, especially in autumn and winter, and the stinging sensation intensifies when applying medication. This is a signal that low immunity has reduced the skin’s resistance.

Causes: Low immunity reduces sebum secretion (sebum is the skin’s "natural protective film"). Meanwhile, the renewal of stratum corneum cells slows down, making it impossible to repair damaged areas in a timely manner, leaving the skin fragile, sensitive, and prone to external irritation.

3.Frequent Colds and Slow Recovery in Vitiligo Patients

Manifestations: You may catch a cold easily from a little wind or after changing into thinner clothes, and symptoms such as nasal congestion and coughing last 1–2 weeks before improving, which is slower than the recovery rate of healthy people. Some patients may also have low-grade fever and dry, sore throat. This is a typical sign that the immune system cannot resist external viruses in a timely manner. In addition, immune fluctuations during a cold may indirectly affect the stability of white patches.

Causes: When immunity is normal, immune cells (such as white blood cells and lymphocytes) in the body can quickly identify and eliminate viruses. When immunity is low, immune cells have "insufficient combat effectiveness" and cannot eliminate viruses in a timely manner, leading to prolonged colds. At the same time, the body mobilizes a large amount of immune resources to fight viruses, which indirectly inhibits the activity of melanocytes and affects the stability of white patches.

4.Slow Wound Healing in Vitiligo Patients

Manifestations: After minor bumps and scrapes, small wounds may not scab over for more than a week, or the scabs are prone to leaving red marks and exuding fluid repeatedly. Even mild skin friction may cause local redness and damage. This is a signal that low immunity impairs the skin’s repair ability. In addition, trauma may induce the isomorphic response of vitiligo.

Causes: Low immunity prolongs the "inflammatory response" at the wound site, and repair cells cannot synthesize collagen and new skin cells in a timely manner. Meanwhile, local immune disorders caused by trauma may activate the pathogenesis of vitiligo and induce new white patches.

5.Chronic Fatigue and Poor Mental State in Vitiligo Patients

Manifestations: You may feel fatigued even without doing strenuous work, and still feel sleepy during the day despite sleeping 7–8 hours at night, along with increased irritability and anxiety. Some patients may also experience decreased appetite and slight weight fluctuations. This is a sign that low immunity leads to "insufficient energy supply" for bodily functions. Chronic fatigue will further disrupt the immune rhythm, forming a vicious cycle.

Causes: When immunity is low, the body is in a state of "chronic stress" and secretes more "cortisol" (a stress hormone). This hormone not only consumes a large amount of energy, but also inhibits the activity of immune cells, while affecting mood and sleep, forming a cycle of "fatigue → lower immunity → more fatigue".

Reasons: When immunity is low, the body is in a "chronic stress state" and secretes more "cortisol" (a stress hormone). This hormone not only consumes a lot of energy, but also inhibits the activity of immune cells. Meanwhile, it affects mood and sleep, forming a cycle of "fatigue → lower immunity → more fatigue".
