Food allergies arise when the immune system mistakenly identifies proteins in certain foods as dangerous, triggering a defensive response against these harmless substances. Citrus fruit allergies, including grapefruit, are relatively common, particularly among adults rather than children.
Common indicators of a grapefruit allergy may include:
- Itching or swelling in the mouth, tongue, or lips
- Skin issues such as eczema, hives, or redness and swelling on the face or limbs
- Digestive problems like stomach pain, nausea, vomiting, or diarrhea
- Respiratory issues such as a runny or congested nose, coughing, sneezing, wheezing, or trouble breathing
- Cardiovascular symptoms like a sudden drop in blood pressure, dizziness, or fainting
In cases of anaphylaxis, characterized by symptoms such as nausea, vomiting, a weak or rapid pulse, breathing difficulties, confusion, or loss of consciousness, seek emergency medical help immediately, as this condition can be life-threatening.
Symptoms of a citrus allergy can arise from consuming even a small quantity of citrus fruit or juice, touching the peel, or inhaling airborne particles. These symptoms may manifest instantly or take several hours to appear after exposure to citrus fruits.
If you experience any of the aforementioned symptoms after consuming or encountering grapefruit, consult an allergist for proper diagnosis and treatment. Additionally, even without a grapefruit allergy, grapefruit can cause negative reactions when consumed alongside certain medications. Compounds in grapefruit can disrupt medication metabolism, leading to prolonged presence in the body and potentially hazardous levels. Always consult your doctor or pharmacist about grapefruit interactions when starting a new medication.
