Digestive Problems
People with fructose allergy often experience digestive problems, such as bloating, gas, and diarrhea. This is typically the result of the body’s inability to fully absorb fructose, causing it to be fermented by bacteria in the gut.
Abdominal Pain
Abdominal pain is another common symptom of fructose allergy. This pain is often severe and can be associated with the digestive problems mentioned earlier. It's typically caused by inflammation and irritation in the gut.
Hives
Hives are a skin reaction that appears as itchy red bumps or welts. They occur when the body regards fructose as a harmful substance and reacts by releasing histamines, which can cause inflammation and itching on the skin.
Wheezing and Difficulty Breathing
Some people with a fructose allergy may experience respiratory symptoms such as wheezing and difficulty breathing. This reaction is generally a sign of a severe allergic reaction, known as anaphylaxis, which requires immediate medical care.
Fatigue
Fatigue can also be a symptom of fructose intolerance, given the body's inability to absorb and metabolize fructose efficiently. This can lead to a drop in energy levels, making the individual feel tired and fatigued.
Mental Confusion
Some individuals with a fructose allergy may experience foggy thinking or mental confusion. This is due to the body's inability to metabolize fructose properly, which can result in low blood sugar levels, leading to mental confusions and concentration difficulties.
