Fish is an indispensable part of most of our meals, isn't it? The smell of a chili sauce cooked at night, or the taste of a piece of fish eaten with rice at noon... Ah! But imagine, what if some people can't even touch this fish? What if they suddenly feel sick even after eating a little? Yes, today we are going to talk about a topic that is not talked about much among many people, but is very important to know. That is fish allergy, or `(Fish Allergy)`.
What exactly is a fish allergy?
Simply put, a fish allergy is a hypersensitivity of our immune system to certain proteins found in fish. To put it simply, our body thinks these proteins are harmful invaders. It then starts to fight these "invaders."
Now you might be thinking, "Are seafood allergies and fish allergies the same thing?" Yes, there is a slight difference. When we say ``Seafood``, it includes both fish (e.g., crabs, tuna) and shellfish (e.g., shrimp, crabs, mussels). These two types are biologically different. So, if someone has a fish allergy, they won't have a problem eating shrimp, unless they also have a separate ``Shellfish Allergy``.
Another thing is that some people may be allergic to only a few types of fish and may be fine eating others. However, doctors often recommend that if you are allergic to one type of fish, it is safest to avoid all other types of fish.
This allergy is not only caused by eating fish. Sometimes, this condition can occur even after catching fish or inhaling vapors from cooking fish. The sad thing is, it can occur at any age. Even someone who has eaten fish without any problems before can suddenly develop this allergy. While some food allergies go away over time, if you develop a fish allergy, it is often lifelong .
What are the symptoms of this allergy? How do we recognize it?
When someone has a fish allergy, when they eat fish (sometimes just by touching it or smelling it), their body's immune system is activated and releases chemicals like histamine. This is what causes the symptoms. See if these symptoms sound familiar to you:
- Difficulty breathing, wheezing
- Cough
- Hoarseness, change in voice
- Feeling of tightness in the throat (throat tightness)
- Stomach ache, nausea, vomiting
- Diarrhea
- Itchy eyes, watery eyes, swollen eyes
- Skin rash, hives
- Red spots on the skin
- Swelling
- A sudden drop in blood pressure can cause dizziness, fainting, and even loss of consciousness.
The important thing is that these symptoms do not occur in the same way for everyone. Even the same person can experience different symptoms at different times.
There is a dangerous condition that we need to pay special attention to here. That is a severe allergic reaction called anaphylaxis . This can be life-threatening . Sometimes, the symptoms start with minor ones and suddenly become severe. You may have difficulty breathing and lose consciousness. This can affect several parts of the body. It can be really dangerous if not treated quickly. Therefore, if you suspect that you have a fish allergy, you should definitely seek medical advice. A specialist can find out exactly what types of fish you are allergic to. Otherwise, the best thing to do is to avoid all types of fish.
How do you treat a fish allergy? What to do in an emergency?
If your child or someone you know has a fish allergy (or other severe food allergy), it's essential to always carry two epinephrine shots. This is a life-saving medication.
Epinephrine is a prescription medicine. It usually comes in a small, easy-to-carry auto-injector (such as an EpiPen). Your doctor will show you how to use it. Older children can also learn to inject themselves. Keep this medicine with you at all times. It is not recommended to leave it in the school locker or in the nurse's office.
Your doctor may also give you an Allergy Action Plan . This will help you prepare for, recognize, and treat an allergic reaction. Share this plan with everyone who cares for your child (relatives, school officials, parents of friends). It is also important for your child to wear a medical alert bracelet .
Every second counts during an allergic reaction.
If your child develops severe allergic symptoms (such as swelling of the mouth or throat, difficulty breathing), give them an epinephrine injection immediately . Or, if the symptoms are seen in two different body systems (for example, skin rash with vomiting), give them an epinephrine injection immediately. Then call 911 immediately for an ambulance, or take them to the nearest emergency room immediately . Keep your child under medical supervision. Sometimes, even when the worst of the symptoms seem to have passed, a second wave of symptoms can occur.
Sometimes, allergists recommend keeping over-the-counter antihistamines on hand. These can help control minor allergy symptoms. But remember, they should only be given after an epinephrine injection in the event of a severe reaction. They should never be used as a substitute for epinephrine.
What else do we need to know if we have a fish allergy? How can we be careful?
If allergy testing confirms that your child has a fish allergy, your doctor will give you a set of instructions to protect your child. To prevent allergic reactions, your child should avoid eating fish altogether . Also, do not feed your child any food that may contain fish as an ingredient. For those who are sensitive to the smell of fish cooking, it is best to avoid places like restaurants and fish markets that cook fish.
Reading food labels is very important!
Always check the label of a food to see if it contains fish. In countries like the United States, it is required by law to list the major allergens on the food label. In Sri Lanka, this information is now available on many products. The ingredients list may include "fish" or the words "Contains fish" after the list.
Some foods may look good on the ingredient list, but when they are prepared, they can come into contact with fish. This is called cross-contamination . Imagine, if you cut fish and vegetables on the same board? If you fry fish and potato slices in the same oil? Things like that.
Look for warnings on the labels such as ``May contain fish'', ``Processed in a facility that also processes fish'', or ``Manufactured on equipment also used for fish''. Not all companies provide these labels. So if in doubt, call or email the company to confirm.
Be very careful in restaurants!
Cross-contamination is common in restaurant kitchens. This risk is increased because the same cutting boards, knives, pans, and oil are used for both fish and other foods.
This risk is especially high in seafood restaurants. Some people avoid such places altogether. When eating out, it is best to avoid fried foods. Because in many places, things like chicken, French fries, and fish are fried in the same oil.
Keep these things in mind when eating out:
- Always keep two unexpired epinephrine shots with your child (or yourself).
- Be clear about your fish allergy to those preparing and serving food.
- Sometimes, it might be better to take a safe, reliable meal from home.
- If the restaurant manager, chef, or owner is not very receptive to your request, it is wise to avoid eating there.
Be careful about this at school too:
There may also be a risk of cross-contamination in school cafeteria food. Talk to the staff about this. Some parents choose to pack their child's meals from home. This may be safer.
In summary... (Take-Home Message)
Although fish allergy is a serious condition, it can be managed well if you are properly informed and follow the necessary precautions.
- Always carry two doses of `(Epinephrine)` with you. Know exactly how to use it.
- Read food labels carefully. Be especially aware of ``(Cross-contamination)``.
- Explain this allergy to your child, family, teachers, and other caregivers.
- In an emergency, don't panic, act quickly.
- Don't panic. Awareness and preparation are the most important things here. If you have any doubts, definitely seek medical advice. It would be very helpful to meet with an allergist to discuss this further.
Wishing you and your family good health!
