Food allergies can manifest in a wide range of symptoms, making them sometimes difficult to diagnose. One common symptom is the development of skin rashes, such as hives or eczema, after consuming a particular food. For example, a person with a peanut allergy may experience hives shortly after eating a peanut-containing product.

Additionally, food allergies can lead to digestive issues, including nausea, vomiting, diarrhea, and abdominal pain. For instance, someone with a lactose intolerance may experience severe stomach cramps and diarrhea after consuming dairy products.

It's important to note that food allergies can also cause respiratory symptoms, such as sneezing, coughing, or difficulty breathing. For example, individuals with a shellfish allergy may experience wheezing and shortness of breath after eating shellfish.

Understanding the diverse symptoms of food allergies is crucial for proper diagnosis and management. If you suspect that you or someone else may have a food allergy, it's essential to consult a healthcare professional for evaluation and potential testing.
