Flare up refers to a sudden, intense, and often temporary increase or worsening of a condition, symptom, or an ongoing problem. It typically describes a sudden outbreak or recurrence of a disease, illness, or medical condition, resulting in more severe or bothersome symptoms. Flare-ups can occur in various medical conditions such as autoimmune disorders, chronic illnesses, infections, allergies, or injuries.
In the context of chronic conditions, such as asthma, arthritis, or irritable bowel syndrome, flare-ups can be triggered by various factors including stress, infections, weather changes, allergens, or certain activities. These episodes tend to manifest with a sudden intensification of symptoms like pain, inflammation, difficulty breathing, itching, or redness. Flare-ups are often characterized by their unpredictable nature and can subside on their own or with appropriate treatment.
Additionally, the term is also used outside of medical contexts to describe sudden bursts of emotion, conflict, or violence. For example, a verbal argument can suddenly escalate and "flare up" into a physical confrontation. Similarly, tensions between countries or political entities can "flare up" into conflicts or wars.
Overall, whether it pertains to a medical condition or interpersonal strife, a flare-up implies a sudden and often transient exacerbation of a situation or disturbance.
