Recurring hives need not be an allergy and may be chronic spontaneous urticaria, says Thane doctor

When hives break out on the body, a person's first instinct is to look for the cause. Suspicion falls on a food, a medicine or a skin product. But what if there is no clear cause or trigger and the hives keep coming back? Dr Vishalakshi Vishwanath, consultant dermatologist at KIMS Hospitals, Thane, has explained chronic spontaneous urticaria, or CSU.

According to Dr Vishwanath, in chronic urticaria hives, swelling or both keep recurring for more than six weeks. CSU is one form of it, in which these symptoms appear suddenly even without any external cause or trigger. It is different from an allergic reaction linked to a specific substance. Recognising the difference in time is important, as it helps in getting the right treatment and managing the symptoms effectively.

Dr Vishwanath said, "Recurring hives are not necessarily a symptom of allergy every time. If symptoms keep appearing or flare up again and again without a clear cause, chronic spontaneous urticaria could be the likely reason behind them. Consulting a dermatologist makes it possible to find the real cause of these symptoms and decide the right course of treatment. Timely medical advice becomes very important, especially when the recurring hives begin to disturb sleep, increase restlessness or affect daily life."

Dr Vishwanath has listed five key points to understand the condition. First, hives do not always mean allergy. In hives, red, itchy welts suddenly form on the skin and can appear on any part of the body. They can result from an allergic reaction, but they are also the main symptom of CSU, in which the trouble occurs without any external cause.

So when hives keep recurring, it is not right to assume that a particular food, product or environment is responsible. According to Dr Vishwanath, health experts can make a correct assessment of the actual problem by looking at the pattern of symptoms and the patient's medical history.

Second is the six-week mark. When hives persist for more than six weeks, they are considered chronic urticaria. In CSU, the skin welts usually disappear within 24 hours, but new ones can come up on other parts of the body. So even if the skin looks completely normal between two episodes, the condition can remain active in the body. If a regular note is kept of when hives appear, how long they last and whether swelling accompanies them, this information proves useful for examination during a consultation.

Third, the search for a cause can be exhausting. When symptoms keep returning, people begin changing their diet, switching skincare products or giving up daily habits to prevent a recurrence. But in CSU there is no fixed external factor or trigger that can be found or avoided. Some things may make symptoms worse in some people, but that does not mean those things are the root of the problem. A dermatologist can see whether further tests are needed and can help patients avoid unnecessary restrictions.

Fourth, the effect of CSU is not limited to the skin. Constant itching can break sleep, cause tiredness during the day, and make it hard to concentrate at work or manage everyday tasks. Visible welts or swelling can also cause discomfort or a sense of inferiority in the company of others. Uncertainty over when symptoms will flare up again can add to mental stress. CSU can affect not just the outward appearance of the skin but also overall quality of life and mental health.

Fifth, an accurate diagnosis decides the direction of treatment. Recurring hives can have different causes, so identifying the actual problem is a necessary step towards the right treatment. A dermatologist or allergist can examine the duration and pattern of symptoms and the medical history to decide whether further tests are needed.

Treatment of CSU focuses mainly on keeping symptoms under control. It depends on medical examination and on how the body responds to treatment. When there is no clear allergic cause, merely avoiding suspected substances again and again does not stop the symptoms completely.

Overall, recurring hives should be taken seriously, especially when the trouble lasts for several weeks or keeps returning without a clear reason. Rather than assuming every episode is merely an allergy, understanding the pattern of symptoms and getting a proper examination from a dermatologist can help patients manage these symptoms more effectively.
