An allergic reaction to cashew generally affects the skin, respiratory and digestive system. Throughout the years, the tree nut has gained a reputation of being a serious ailment. Even though peanut remains as a common form of food allergy, cashew might pose as a higher risk for anaphylaxis.
What are the skin reactions?
The initial symptoms that involve the skin include itchiness or tingling in or around the mouth. These are likely to arise within minutes of ingesting or directly holding cashew or food that contains the nut.
Skin lesions including swelling and hives are also likely. Elevated, reddened, itchy welts in varying sizes might also develop at random on the skin.
Digestive and respiratory effects
An allergic response to cashew might trigger symptoms of asthma or hay fever if the allergens are ingested or inhaled. Stuffed or runny nose, itchy eyes, coughing and itchiness on the root of the mouth are the usual respiratory symptoms. Wheezing might also be present which is an indication of constricted airways. Other signs that might be present include chest tightness, shortness of breath and chest pain.
Those who are highly sensitive to cashew might also experience digestive symptoms such as vomiting and stomach pain. The severe symptoms might include projectile vomiting, diarrhea, nausea or difficulty swallowing. If the individual has a swollen throat or tongue, it can block the airway or might be an indication of swelling within the digestive tract.
Risk for anaphylaxis
An allergy to cashew is likely to trigger a severe allergic reaction or anaphylaxis. The signs of this potentially dangerous reaction include:
- Swollen throat
- Rapid pulse rate
- Airway constriction
- Loss of consciousness
Remember that inhaling or ingesting even trace amounts of cashew can trigger anaphylaxis. This reaction can develop abruptly and become dangerously rapidly, thus immediate medical care is vital.
