5.1FoodAllergySymptoms

Foodallergiescancauseawiderangeofsymptomsthatcanaffectdifferentpartsofthebody.Someofthecommonsymptomsoffoodallergiesinclude:

1.SkinReactions:Itchyskin,hives,eczema,andswelling.

2.GastrointestinalSymptoms:Nausea,vomiting,abdominalpain,diarrhea,andbloating.

3.RespiratorySymptoms:Runnyorstuffynose,sneezing,wheezing,coughing,shortnessofbreath,andasthma.

4.CardiovascularSymptoms:Lowbloodpressure,rapidheartbeat,fainting,andevencardiovascularcollapseinseverecases.

5.2DrugAllergySymptoms

Similartofoodallergies,drugallergiescanalsocauseawiderangeofsymptoms.Commonsymptomsofdrugallergiesinclude:

1.SkinReactions:Rashes,hives,itching,andswelling.

2.RespiratorySymptoms:Wheezing,shortnessofbreath,andcoughing.

3.GastrointestinalSymptoms:Nausea,vomiting,anddiarrhea.

4.Anaphylaxis:Thisisasevere,life-threateningallergicreactionthatcancausedifficultybreathing,adropinbloodpressure,andlossofconsciousness.
