What is a fish intolerance or allergy?
Fish is amongst the healthiest of foods. It is rich in omega-3 fatty acids, calcium, phosphorus, zinc, magnesium, and other minerals, along with iodine and iron. Health authorities around the world recommend eating fish multiple times a week.
Unfortunately, some individuals struggle with fish, experiencing a range of unpleasant symptoms after eating this dietary staple. But it’s not always easy to work out whether it’s the inconvenience of a fish intolerance or the potentially serious health risks posed by an allergy.
The difference between allergies and intolerance
Although the terms allergy and intolerance are often used interchangeably, these are in reality two separate conditions and it’s important not to confuse the two.
Fish Allergy
Allergies involve the immune system. In affected individuals, antibodies respond to foods and other substances as though they were pathogens, triggering reactions that would normally be deployed against infections and disease – and these in turn cause allergic symptoms. For example, someone with a fish allergy might experience:
- Symptoms of asthma
- Skin rashes or hives
- Sneezing or nasal congestion
- Headaches
- Stomach pains and cramps
- Nausea
- Diarrhea
Some people may also experience anaphylaxis or anaphylactic shock after eating fish. Typical symptoms include a fall in blood pressure, difficulty breathing, lightheadedness, and swelling of the tongue and throat. This is the most extreme form of allergy and one that can be life-threatening without rapid medical intervention. Anaphylactic reactions to fish are relatively rare when compared to other triggers, but they do occur, so taking precautions is sensible.

Taking action
If you regularly feel ill after eating fish, talk to your GP. If they suspect you may have an allergy, they will refer you for specialist testing.
Meanwhile, adjust your shopping habits accordingly. Fish fingers, seafood broth, sushi and haddock fillets are of course all off the menu (at least for now), but do bear in mind that the inclusion of fish in a particular product is not always obvious. Fish extracts can also be found in such products as:
- Salad dressing
- Taramasalata and similar spreads
- Some sauces – for example, Worcestershire sauce
- Asian foods prepared with fish-based sauces, as well as fried rice and spring rolls
People who are very sensitive to their allergic triggers may experience severe symptoms when exposed to even small quantities in processed food products. So you will need to acquire the habit of reading food labels carefully.
But what if the allergy tests are negative but you still experience unpleasant bouts of indigestion after eating fish? Then the chances are good that you have developed an intolerance. But how do you find out for sure?
Take a test
A food intolerance home testing kit is one avenue worth exploring. Take a painless finger-prick blood sample and you will receive a detailed analysis, indicating the responses made by an antibody called IgG to multiple food substances: including fish. The digestive problems caused by a food intolerance can cause food particle build-up, damaging the inner lining of your gut and triggering IgG antibodies.
Whether you need to avoid fish permanently or just for a while, think about the nutrients it supplies so well. Rearrange your diet so that your body will receive a rich supply of protein, minerals, omega-3s and iron from other sources. You may end up feeling better than you have in years.
