Allergy, Spinach in Reay Road West, Mumbai

Spinach may not be a food item consumed regularly. However, it is common in dishes like pasta, eggs, and salads. Although it is not among the top allergens, some people may have a spinach allergy.

Like any other food allergy, the route of exposure for spinach allergy is consuming foods containing the leafy vegetable spinach. Symptoms of this allergy include:

• Gastrointestinal problems
• Respiratory issues
• Nasal problems
• Skin issues

Spinach has a very high histamine level. Hence, it can cause issues for people with histamine intolerance. While the spinach allergy can be due to reasons other than histamine content, it is common for that to be the cause. 
Allergic reactions due to spinach can cause the following effects on one's body:

• Itching
• Congestion
• Hives
• Vomiting
• Abdominal pains
• Swelling 
• Indigestion 
• Diarrhoea

Sometimes, it may lead to severe symptoms like an anaphylactic shock. In such cases, the blood pressure can drop suddenly, and extreme swelling in the lungs can block airways. Such cases are life-threatening and require immediate medical attention.

It is not uncommon for a food allergy to lead to anaphylactic shocks. Hence, it is recommended that people with a known spinach allergy always carry an epinephrine pen in case an emergency occurs.

Diagnosis for spinach allergy is done through a blood test. The test is almost painless and does not expose the patient to the allergen. Hence, it is preferred over oral and skin tests. Blood tests are also more suitable for children whose skin cannot take the pressure of a pricking test.

Health experts look for a substance called immunoglobulin E (IgE) in the blood. The amount of IgE antibodies produced in response to spinach consumption determines whether or not someone is allergic to it.

A spinach allergy is usually lifelong and cannot be overcome. So, its treatment, for the most part, includes avoiding foods that contain spinach. One can do so by:

• Reading all food labels while buying packaged foods
• Letting the restaurant or hotel know of their spinach allergy when eating out
• Ensuring that the host knows they are allergic to spinach when eating at someone’s place as a guest

Different methods have to be adopted to counter the effects in the case of spinach exposure. For mild skin reactions, topical histamine creams can be used to reduce the impact. Antihistamine drugs are also helpful in reducing inflammation.

Although anaphylactic reactions are uncommon when it comes to spinach allergy, they may still occur. In such cases of extreme reactions, the patient should be brought to medical attention immediately.

Since a spinach allergy is often associated with high histamine levels, switching to a low histamine diet can also prove beneficial.

Apollo 24|7 offers a spinach allergy test that helps one know if they are allergic to the leafy vegetable. The report is generated within seven days.
