Allergies can start at any age, from infancy to adulthood. Some allergies may develop early in life, while others may develop later on. The timing of when allergies start can vary depending on various factors, including genetics, environmental exposures, and immune system responses.
In some cases, allergies may be present from birth, such as in the case of food allergies or allergies to pet dander. Other allergies, such as seasonal allergies (e.g., hay fever) or environmental allergies (e.g., dust mites, mold) may develop later in life, often during childhood or adolescence, as a person’s immune system becomes sensitized to specific allergens.
It’s important to note that allergies can also develop suddenly in adulthood, even if a person has not experienced allergies before. It’s not uncommon for individuals to develop new allergies later in life due to changes in their immune system or exposure to new allergens.
If you suspect that you or someone you know may have allergies, it’s best to consult with a healthcare professional for proper diagnosis and management. Allergists and immunologists are medical specialists who can help diagnose and treat allergies effectively.
