How Long do Hives from Food Allergy Last?

Some people suffer from food allergies which cause hives. It is unknown how long these hives will last, but some believe that they may persist for several weeks or even a few months. Some people take antihistamines to control their symptoms, but others find relief by avoiding the allergen.

Some people have food allergies and get hives after eating certain foods. It is not always easy to tell when a food allergy is causing a reaction, but some clues may include: redness, swelling, itchiness, and difficulty breathing. Some people have hives for a short time and others have them for a longer period. There is no one answer to this question because everyone’s reaction to food will be different.

How Long do Hives from Food Allergy Last?

There is no one answer to this question since it depends on the person’s food allergy and the severity of their symptoms. Generally speaking, hives from food allergies can last anywhere from a few minutes to a few hours, but they usually start to dissipate within a few hours or a few days. Some people may experience milder reactions that don’t last as long, while others may have more severe reactions that can last for days or even weeks.

Hives from food allergies can last anywhere from a few days to a couple of weeks. The duration is based on the severity and type of food allergy the person has. For example, hives from milk allergy will usually last a shorter amount of time than hives from egg allergy.

Food allergies are a growing problem in the United States. In 2008, food allergies were reported by almost 2% of children and about 6% of adults. The prevalence of food allergies has increased dramatically in recent years, and some experts believe that this increase is due to the increased use of food additives in processed foods. 

It is not known for certain how long hives from a food allergy will last. Some people who have had hives from a particular food for many years do not develop any other allergic reactions to that food. Others who have had only occasional episodes of hives from that food may develop other allergic reactions after eating that food again. It is important to consult with a physician if you experience an allergic reaction after eating something that you are known to be sensitive to.
