What are the indications of potato allergy?

Individuals who are suffering from allergic reactions shortly after consuming potatoes must take note of the signs and symptoms and consult a doctor for an accurate diagnosis. Remember that the symptoms of food allergy are strikingly similar to the signs of common cold or flu but can progress to a deadly anaphylactic shock which is a severe reaction that requires immediate emergency care.

Even though many children eventually outgrow potato allergies, adults who end up with one are at risk for allergic reactions for a lifetime. Take note that having allergies can increase the possibility for developing other forms of allergies as well. Those who are allergic to birch pollen or latex face an increased risk for potato allergy.

Swelling and itchiness

Right after eating potatoes, the histamine-induced inflammation triggers the distinctive allergy symptoms of swelling and itchiness. These usually start at the point of contact along with itchiness in the mouth, lips, tongue and throat. As the allergens are transported via the bloodstream, the itchiness can also spread up to the eyes and skin.


Difficulty in swallowing or breathing as well as an erratic pulse might indicate the start of anaphylaxis.

The swelling can occur as bumps in the mouth or swelling of the tongue. The inflammation can spread to the eyelids and face or trigger an elevated, red-colored rash on the skin. Those who have an allergy to birch pollen or latex allergy might end up with only this allergic reaction and only after consumption of uncooked potatoes.

Breathing and heart issues

Difficulty in swallowing or breathing as well as an erratic pulse might indicate the start of anaphylaxis. As the immune system wrongly identifies the potato in the body as a threat, some can end up with a sharp drop in the blood pressure that can occur at the same time in which inflammation disrupts with proper respiration.

Inflammation in the throat can clog up the airways, transporting reduced amount of oxygen via the blood to the brain. The symptoms of confusion, slurred speech, wheezing and dizziness can also occur. These symptoms require immediate emergency care since it might be followed by loss of consciousness and even death.

Gastrointestinal issues

The abdominal and intestinal symptoms can manifest within an hour or two at the pace of digestion and might be preceded with nausea in most cases. Individuals who have potato allergy might experience mild to severe abdominal pain, vomiting, intestinal cramps and diarrhea.

The gastrointestinal effects of allergic reactions can occur abruptly or gradually. Once combined with respiratory and cardiovascular issues, the condition can become debilitating. In addition, even though the symptoms subside shortly, the condition will linger with the high risk for anaphylaxis.

Once an individual is suspected with potato allergy, it is best to schedule an appointment with a doctor so that proper assessment can be carried out as well as allergy testing either a skin prick test or blood test. The testing will determine the exact allergen that triggers a reaction.
