overview
Shellfish allergy is an abnormal response by the body’s immune system to proteins in certain marine animals. The marine animals in the shellfish category include crustaceans and mollusks such as shrimp, crab, lobster, octopus, oysters, scallops, and others.
Some people who are allergic to shellfish will react to all shellfish. others only respond to certain types. The reactions range from mild symptoms – such as hives or nasal congestion – to severe and even fatal symptoms. Shellfish allergy treatment in Nizamabad
symptom
Symptoms of shellfish allergy usually appear between a few minutes and an hour after eating shellfish. They can include:
- Hives, itching, or eczema (neurodermatitis)
- Swelling of the lips, face, tongue and throat or other parts of the body
- Wheezing, nasal congestion, or difficulty breathing
- Abdominal pain, diarrhea, nausea, or vomiting
- Dizziness, lightheadedness, or fainting
The reasons
All food allergies are caused by an overreaction of the immune system. With a shellfish allergy, your immune system incorrectly identifies a certain protein in shellfish as harmful and triggers the production of antibodies against the shellfish protein (allergen). The next time you come into contact with the allergen, your immune system releases histamine and other chemicals that cause allergy symptoms. Shellfish allergy treatment in Nizamabad
Risk factors
You are at an increased risk of developing shellfish allergy if allergies of any type are common in your family.
Although people of any age can develop a shellfish allergy, it is more common in adults. In adults, shellfish allergy is more common in women. In children, shellfish allergy is more common in boys.
Complications
In severe cases, shellfish allergy can lead to anaphylaxis, a dangerous allergic reaction characterized by a swollen throat (narrowing of the airways), rapid heartbeat, shock, and dizziness or lightheadedness. Anaphylaxis can be life threatening.
If you are allergic to shellfish you may have an increased risk of anaphylaxis if:
- You have asthma
- You have an allergic reaction to very small amounts of shellfish (extreme sensitivity)
- You have a history of foodborne anaphylaxis
prevention
If you have a shellfish allergy, the only way to avoid an allergic reaction is to avoid all shellfish and products that contain shellfish. Even traces of shellfish can cause serious reactions in some people.
- Avoid shellfish
- Be careful when you eat out. When eating out, always make sure that the pan, oil, or shellfish utensil is not being used to prepare other foods as well, which will lead to cross-contamination. It may be necessary to avoid eating in seafood restaurants where the risk of cross contamination is high.
- Read the labels. Cross-contamination can occur in stores processing or displaying other foods near shellfish and during manufacture. Read the food labels carefully. Shellfish allergy treatment in Nizamabad
