How to respond in Spanish when someone asks if you have allergies

Introduction

Learning how to respond to questions about allergies in Spanish is an essential skill for anyone traveling to Spanish-speaking countries or communicating with Spanish speakers. Whether you are dining at a restaurant, visiting a doctor, or simply chatting with new friends, being able to confidently discuss your allergies in Spanish could be important for your health and safety. This comprehensive guide will teach you the most common and practical ways to respond when someone asks if you have allergies, covering both simple answers and more detailed explanations that will help you navigate real-world conversations with ease.

Understanding the Question: ¿Tienes Alergias?

Before you can respond appropriately, you need to recognize when someone is asking about your allergies. The most common question you will encounter is ¿Tienes alergias?, which translates to Do you have allergies? in English. This is the informal way of asking, using the second-person singular form of the verb tener. If someone is being more formal with you, they might ask ¿Tiene alergias?, which is the polite form used with people you do not know well or in professional settings.

You might also hear variations such as ¿Eres alérgico a algo? (Are you allergic to something?), where alérgico is the adjective form meaning allergic. In some regions, people might ask ¿Padeces de alergias?, which uses the verb padecer meaning to suffer from, though this is slightly less common in everyday conversation.

Simple Yes and No Responses

The most straightforward way to answer is with a simple affirmation or denial. If you do not have allergies, you can simply respond No, no tengo alergias, which means No, I do not have allergies. This is the most direct and commonly used response.

If you do have allergies, you would say Sí, tengo alergias, meaning Yes, I have allergies. However, in many practical situations, it is helpful to provide more information about what you are allergic to, as simply stating that you have allergies may prompt follow-up questions.

Another simple option is to say No soy alérgico a nada (I am not allergic to anything) or Soy alérgico a… (I am allergic to…). These responses use the verb ser with the adjective alérgico, which is equally valid and commonly used in Spanish-speaking regions.

Specifying Your Allergies in Detail

When you need to explain what you are allergic to, the structure Soy alérgico/alérgica a… is very useful. Note that alérgico is masculine and alérgica is feminine, so adjust based on your gender. For example, you might say Soy alérgico a los mariscos (I am allergic to shellfish) or Soy alérgica a los cacahuetes (I am allergic to peanuts).

Here are some common allergens and how to mention them:

Los frutos secos (tree nuts and peanuts)
Los mariscos (shellfish)
El pescado (fish)
Los huevos (eggs)
La leche (milk)
El trigo (wheat)
El gluten (gluten)
La soja (soy)
Las fresas (strawberries)
Los tomates (tomatoes)

You can combine multiple allergies by using y (and): Soy alérgico a los cacahuetes y a los frutos secos (I am allergic to peanuts and tree nuts). If you have many allergies, you might say Tengo varias alergias (I have several allergies) and then list them when asked for details.

Using Tengo Alergia A (Singular Form)

Another common way to express allergies is using the singular form Tengo alergia a…, which translates to I have an allergy to… This phrasing is especially useful when you have one primary allergy or want to emphasize a particular one. For instance, Tengo alergia a la penicilina (I have an allergy to penicillin) is a critical statement to make to a doctor or pharmacist.

The difference between using Soy alérgico a and Tengo alergia a is subtle. Both are correct, but tengo alergia a might feel slightly more natural when discussing medical situations, while soy alérgico a is commonly used in everyday conversation. Native speakers use both interchangeably, so you should feel comfortable using either construction.

Expressing Severity and Reactions

In some situations, you may need to convey how serious your allergies are. Spanish speakers often use tengo una alergia grave (I have a severe allergy) or tengo una alergia leve (I have a mild allergy) to indicate the severity. If your allergy could be life-threatening, you might say Tengo una alergia muy peligrosa (I have a very dangerous allergy) or Tengo una alergia anafiláctica (I have an anaphylactic allergy).

When describing your symptoms, useful phrases include Me causa vómitos (It causes me vomiting), Me hace hinchar la garganta (It makes my throat swell), or Me causa picazón (It causes me itching). If you experience swelling, you can say Me causa inflamación (It causes me inflammation).

Responses in Different Contexts

Restaurant and Food Service Settings:

When dining out, brevity combined with clarity is important. You might say Tengo alergia al marisco (I have a shellfish allergy) or Soy alérgico a los productos lácteos (I am allergic to dairy products). Restaurant staff in Spanish-speaking countries are generally very attentive to allergy concerns, so communicating clearly is crucial. You could also ask ¿Contiene mariscos? (Does it contain shellfish?) or ¿Lleva frutos secos? (Does it have nuts?).

Medical Appointments:

In a doctor’s office, you should be comprehensive. Say Soy alérgico a la penicilina y a los ácaros del polvo (I am allergic to penicillin and dust mites) or provide whatever allergies are relevant to your health. Doctors appreciate detailed information, so do not hesitate to list multiple allergies if you have them.

Casual Social Settings:

With friends or acquaintances, a simple No tengo alergias, pero mi hermana es alérgica a los cacahuetes (I do not have allergies, but my sister is allergic to peanuts) works well when discussing food plans or other allergen-related matters.

Useful Follow-Up Phrases

When someone asks about your allergies, they may follow up with additional questions. Being prepared with responses makes the conversation flow naturally. If asked ¿Qué alimentos evitas? (What foods do you avoid?), you can respond with Evito todos los productos con gluten (I avoid all products with gluten) or Tengo que evitar cualquier cosa con lácteos (I have to avoid anything with dairy).

If asked ¿Qué te pasa cuando comes algo alérgeno? (What happens to you when you eat an allergen?), you might explain Me duele el estómago y tengo náuseas (My stomach hurts and I feel nauseous) or Se me inflaman los labios (My lips swell up).

You may also want to know how to say Llevo un auto inyector de epinefrina (I carry an epinephrine auto-injector) if you have severe allergies, or Tomo antihistamínicos (I take antihistamines) if that applies to your situation.

Regional Variations and Formality

Spanish has many regional variations, and how people discuss allergies can differ slightly. In Spain, you might hear ¿Eres alérgico? more often, while in Latin America, ¿Tienes alergias? is equally common. The vocabulary for allergens can also vary slightly; for example, los cacahuetes (peanuts) in Spain might be los maníes in some Latin American countries.

Formality matters too. With someone you know well, Tengo alergia a los mariscos is perfectly appropriate. With someone you have just met or in professional settings, you might soften it slightly with Tengo que mencionar que soy alérgico a los mariscos (I have to mention that I am allergic to shellfish).

Conclusion

Responding to questions about allergies in Spanish is a practical skill that can protect your health and enhance your ability to communicate confidently. Whether you choose to use Soy alérgico a or Tengo alergia a, the key is clarity and directness. Practice these phrases, adjust them for your specific allergies, and do not hesitate to provide detailed information when necessary. By mastering these responses, you will be well-prepared to handle any situation where your allergies become relevant, from casual dining to medical appointments. Remember that Spanish speakers generally appreciate when foreigners make the effort to communicate about important health matters in their language, so use these phrases with confidence.
