Allergies are a common issue among many people, but it can be especially worrisome when they seem to come on suddenly. It can be a sign of a serious problem, and it’s important to understand why it’s happening and how to treat it. Causes of Sudden Allergies
The most common cause of sudden allergies is exposure to an allergen that wasn’t previously present. This could be a new pet, a new food, a new type of pollen, or even something like a cleaning product. It’s also possible for people to become allergic to something they’ve been exposed to for a long time. This is known as “sensitization.” Sensitization is when the body has become so used to an allergen that it no longer recognizes it as a threat, so it doesn’t create the necessary antibodies to fight it off.
Symptoms of Sudden Allergies
The symptoms of sudden allergies can vary depending on the allergen, but they often include sneezing, coughing, itchy and watery eyes, a runny nose, and difficulty breathing. In more severe cases, the person may experience hives, swelling, and difficulty swallowing.
Diagnosis and Treatment
If you suspect you have a sudden allergy, it’s important to see a doctor right away. Your doctor will likely perform a skin test or a blood test to determine what allergen is causing your symptoms. Once the allergen is identified, your doctor will be able to recommend the appropriate treatment, which may include antihistamines, allergy shots, or immunotherapy.
In some cases, it may be possible to avoid the allergen altogether. This can help to prevent future allergic reactions. However, if the allergen cannot be avoided, your doctor may suggest taking steps to reduce exposure, such as using air filters or wearing a mask.
