I Have Fish Allergies Does This Mean That I Am Also Allergic To Frogs
No: An allergy to fish may not be to all fish. Since frogs are very different than fish, they have many different proteins. It is perfectly possible that you will not be allergic to both fish and frogs because of a common allergen. But, you could be allergic to one thing in fish and another in frogs, for example. ...Read more
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more

Probably: If you have safely eaten frog in the past then you can eat it, no matter what other things you are allergic to. If you have avoided it due to being allergic to fish, the risk should be low. They are different, one is a fish and one is an amphibian. ...Read more
Yes: Shellfish all have very similar proteins and cross reactions can occur. ...Read more
Caution: The allergen for shrimp allergy is a muscle protein. It is a common allergen in all the shellfish.

I have a mild fish allergy. Would it be safe for me to take krill oil? Should I be worried about fish contaminants? I am not allergic to shell fish.
I hear so much abt allergic reactions that I've started avoiding peanuts, fish, etc, even tho I have no food allergies. Overreacting?
Yes: The guidelines that are published for evaluation and treatment of food allergies do not recommend testing without a prior reaction/symptoms after eating. If you have never had any problems with a specific food, avoiding them proactively would be unneccessary. I do admire your desire to be proactive though. ...Read more
Just had allergy testing and am allergic to soy, wheat, beef, fish, cows millk, eggs. What can I eat?
Context: Significance of your test results need to take into account what symptoms you have when eating these foods. If you indeed cannot eat these foods, consider chicken, pork, venison, vegetables, fruits. ...Read more
Allergy test came back highly allergic to all dairy, all wheat, gluten, all yeast, rice, eggs, some fish. Could anything else be wrong? Why so much?
Doubtful results: I wonder if you had your test with a board certified allergist, or was it a random blood test you had with another practitioner. It is unlikely for an adult to be allergic to all these items and I stronly doubt the accuracy of these results. I suggest you consult a board certified allergist to discuss your symptoms and determine the indication for specific testing. ...Read more
I've never had food allergies & tested neg for them, but do have eczema & chronic hives. Does this mean i'll react to big allergens like nuts & fish?
Not necessarily: In fact, your own experience with eating nuts and fish is a much more reliable indicator of whether you're actually allergic than the results of skin testing will be. I think your allergist will tell you the same thing. The best way to determine whether your skin issues are due to allergy is a few weeks' trial of an elimination diet. Ask about it. ...Read more
I have a severe allergy to shell fish. My doc just prescribed keflex, because I am allergic to penicillin, too. I took a benadryl, (diphenhydramine)?
See detail: Being allergic to shellfish and being allergic to antibiotics are two different things. They are not related. However, as the other doctor indicated, patients that are allergic to penicillin should not (in general) take keflex. Your shellfish allergy needs to be taken seriously and not only should you strictly avoid shellfish, you should carry injectable Epinephrine in case you have exposure. ...Read more
I had iodine constant 6 years ago and it nearly killed me. I want to take prenatal vitamins. Am I allergic to fish oil because of the iodine allergy?
Allergy test I took to nuts, fish, milk, soy, was negative. This means, there is no reason for the tongue to swell, and kill me? I have health anxiety
Allergy tests: The tests you had done were food allergens. Although it is encouraging that they are negative, there are other things you could be allergic to, such as aeroallergens: pollens, grasses, trees, weeds and even animals. Any kind of a reaction to allergen could cause tongue swelling. There are other causes of tongue swelling, but allergies & trauma are most common. Not common to kill, though. ...Read more
Important: Important to find out the type of fish first, making sure to differentiate a bony fish from a crustacean. Once that is figured out a blood or skin test is available to help determine what you are allergic to. This can be performed in an allergists office. ...Read more
Not necessarily: But better be cautious, sea food mix would contain shellfish, also shellfish might be cooked in the same pan and contaminates other fish meat, please see an allergist for testing and follow up, meanwhile keep an Epipen (epinephrine) and antihistaminic tablets handy for any accidental exposure, good luck ...Read more
Is my allergic reaction after exercising after seafood because of the exercise or seafood allergy?
Exercise induced: Food associated anaphylaxis is uncommon, but can happen. Wheat and shrimp are the most common culprits. Patients can eat the food without exercising, or exercise without eating the food and be fine. Be very careful to not eat shrimp within 4 hours of exercise and I would suggest not at all on exercise days. You should also see an allergist and have an Epipen (epinephrine) available. ...Read more
Can I have developed an allergy to shrimp or is the seasoning the culprit? I have eaten seafood all my life including shrimp. I recently had some shrimp that I had an allergic reaction to. I beleive it was the seasoning I may have been allergic to.
Based: Based on your history of eating shrimp it is more likely the seasoning is the culprit. One other possibility is that the shrimp was spoiled. The only way to determine if you have a true allergy is to have a sensitivity test performed. ...Read more
Great question: Better to be specific. Shellfish = “crustaceans” (lobsters, "crayfish", prawns, crabs and shrimp) and “molluscs, ” [abalone, oysters, mussels, and squid (calamari)]. Other fish allergies are to “scaly” and “bony” fish, such as cod, haddock, herring, sprat, halibut, mackerel, trout and salmon. Hard to differentiate when they are cooked together! ...Read more
Can I reduce my severe food allergies? I've just learned that I'm allergic to shellfish and nuts. I'm 50 years old and have never had a reaction to any type of seafood, or any other food, until recently. Why would I suddenly develop food allergies? Are th
I'll get itches on my eyelids, arms etc when I eat certain seafood. Does that mean I have allergies?
Most likely: Do you develop hives or get choking sensation, swelling in throat, mouth, lips? Avoid those kinds of seafood that bring on symptoms. See an allergist to be tested. Mild cases may respond to antihistamines, but more severe one may require avoidance & carrying an epi-pen for emergency situations. ...Read more
