It is a known fact that food allergies are quite common. Shellfish allergy particularly to crab is one of the common food allergies. An individual who is allergic to shellfish may or may not be allergic to other types of shellfish. Nevertheless, in most cases, an individual who is allergic to crab will develop an allergic reaction to other types of shellfish such as lobster. A crab allergy can also trigger a severe allergic reaction. With this in mind, it is best to consult a doctor to determine if it is actually an allergic reaction or a different underlying condition.
Symptoms of crab allergy
A skin rash is one of the common symptoms of crab allergy. Take note that the rash can manifest anywhere on the skin and can appear in different ways. The skin rash does not have to be severe and it can appear pinkish in color and itchy. Nevertheless, during a food allergy, it is considered common for a severe rash, hives or swelling on the skin to occur.
An individual with crab allergy can experience breathing difficulties. This is considered as a severe symptom and it would require immediate first aid care. During an allergy, shortness of breath is considered as a major issue and likely caused by the swelling that can block the airway.
Dizziness or lightheadedness is quite common during food allergies. It typically occurs once an allergic reaction affects the ears or nose. This can also occur in a span of a few minutes after eating crab or even hours later depending on the severity of the food allergy. It is important to consult a doctor if dizziness is suspected to be triggered by crab allergy.
Diarrhea and vomiting can occur during food allergies. It simply means that the body is trying to eliminate the toxin. Nevertheless, if diarrhea and vomiting occur, it can lead to dehydration. It is vital to ensure that an individual who is allergic to crab must stay properly hydrated and medical attention is provided.
Once an individual ingested food that can trigger an allergic reaction, chest tightness can occur. This is usually accompanied by other symptoms and the individual will start to experience shortness of breath and panic. Shock can commonly occur during severe reactions thus if tightness of chest occurs, it is best to consult a doctor.
Intense feeling of fear
If the individual starts to panic or immediately feel that something is wrong with the body, it can indicate a warning to a severe allergic reaction. This is usually followed by one of the life-threatening symptoms such as difficulty breathing, severe swelling and anaphylaxis.
What occurs during anaphylaxis?
Anaphylaxis is the entire reaction of the body to an allergy. It involves hives and swelling. Take note that the swelling is usually severe and can occur in the face, eyes and throat. This can lead to the blockage of the airway, thus making it hard to breathe. If timely treatment is not provided, it can affect the heart and even lead to death.
