Fish Intolerance Information

A person with a fish intolerance experiences negative symptoms whenever he or she consumes fish. Fish intolerances are highly individual. A person with a fish intolerance will experience a variety of delayed symptoms after eating fish. These symptoms can be delayed by several hours and even up to a day or more in some cases.

A fish intolerance is not a fish allergy. With a fish allergy, negative symptoms occur shortly after consuming fish, rather than the delayed symptoms that occur with a fish intolerance. Fish allergy symptoms are also much more severe on average than fish intolerance symptoms. Fish allergy symptoms can even be life-threatening. Fish intolerance symptoms are not life threatening. They do, however, make life difficult and uncomfortable for anyone who has a fish intolerance.

As mentioned earlier, fish intolerances are highly individual. People who have a fish intolerance will respond differently to fish than others with a fish intolerance. Some people experience negative symptoms after eating any fish while others may only experience symptoms after eating certain fish. For example, a person may experience negative food intolerance symptoms after eating salmon, but that same person may not feel any differently after eating other fish. In addition, some people may have symptoms after eating a number of different fish, but those symptoms will be more or less severe for some fish than for others. Some may feel similar food intolerance symptoms after eating any type of fish.

Due to the variety of symptoms and the delay between eating the food in question and experiencing the symptoms, many people are unaware that they have a food intolerance.

What is a Fish Intolerance?



Food intolerances can either be digestive intolerances or immune intolerances. When a person has an immune intolerance, the body responds to eating certain foods with an immune response. With a digestive food intolerance (such as a fish intolerance) a person has a difficulty properly digesting, absorbing or processing fish or a part of fish.

Some people with a fish intolerance will be able to consume small amounts of fish without experiencing issues while others will feel negative symptoms after eating any amount of fish. As mentioned earlier, fish intolerances and fish intolerance symptoms vary greatly from person-to-person.

Digestive Fish Intolerance Symptoms



There are a number of different fish intolerance symptoms. A person with an immune intolerance will experience issues and will not feel well, however these feeling manifest differently in each individual. Therefore, it is not possible to accurately list common immune intolerance symptoms.

With a digestive fish intolerance, people will also react differently. However, there are some symptoms that appear more frequently. The type of symptoms and the severity of those symptoms will still vary from person-to-person.

Digestive fish intolerance symptoms include bloating, excessive gas, stomach cramping, stomach pain and other stomach-related issues. They also include nausea, heartburn, vomiting, headaches, diarrea and many other symptoms. Fish intolerance symptoms take longer to develop. They often occur several hours after consuming the offending food and, in some cases, they can be delayed by up to a day or more.

Fish Intolerance Treatment



Removing fish from your diet will stop fish intolerance symptoms. If you have issues with only certain types of fish, you should be able to remove only those types. If all types of fish cause you to experience negative fish intolerance symptoms, you will want to remove all types of fish.

In many cases, you will not need to remove the foods from your diet permanently. With many fish intolerances, you may be able to start eating fish again at a later date without experiencing negative symptoms. This should be done under the advice of a medical professional.

While avoiding fish is typically quite easy, a person with a fish intolerance should still take note of labels. Some unexpected foods may contain fish oils or other parts of fish. Another point to pay attention to is that many types of fish contain many important nutrients. Fish and other seafood are sources of omega-3 fats and fish is also high in vitamin D and protein. There are also a number of other health benefits to eating fish. If you are removing fish from your diet, you should ensure that you are getting these important nutrients from other sources.
