These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.

Symptoms may include red eyes, an itchy rash, runny nose, shortness of breath, or swelling.

Food intolerances and food poisoning are separate conditions.

Medicine (British English; American English) is the science and practice of the diagnosis, treatment, and prevention of disease.

The word "medicine" is derived from Latin medicus, meaning "a physician".

Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness.

Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls", from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease.

A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others.

For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual).

Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong.

In other cases they are specific even to the point of being pathognomonic.
