What Causes Allergies?
Allergies occur when your immune system overreacts to substances that are normally harmless. Your immune system makes antibodies to fight off harmful invaders like bacteria and viruses. When you have allergies, it mistakenly identifies something safe, such as pollen or pet dander, as a threat and releases chemicals like histamine that cause allergy symptoms.
Anyone can develop allergies at any age, especially if allergies run in the family. In the Houston area, seasonal pollen and year-round humidity can make allergies especially common. Frequent causes include:
- Environmental allergens such as cottonwood, tree and grass pollen, ragweed, dust mites, and mold
- Pet dander
- Medications, especially penicillin-based antibiotics
- Insect stings from bees or wasps
- Foods such as peanuts, tree nuts, dairy, shellfish, eggs, wheat, and soy
When Should You See a Doctor for Allergies?
Even mild allergies can become more serious over time, and allergies can significantly reduce your quality of life. Schedule an evaluation if you regularly experience:
- Sneezing or coughing
- Red, itchy, or watery eyes
- Stuffy or runny nose
- Hives or rashes
- Swelling
- Wheezing or shortness of breath
- Itching of the skin, eyes, or throat
Food allergies may also cause swelling of the lips, tongue, or throat. In severe cases, an allergic reaction can lead to anaphylaxis, a life-threatening emergency that requires immediate care. Call 911 if you have trouble breathing or throat swelling.
Allergy Testing at Houston Family MD
We offer convenient in-office allergy testing so you do not have to wait for a specialist referral. Skin scratch tests expose small areas of skin to tiny amounts of common allergens to see which ones cause a reaction. Blood tests measure allergy-related antibodies and are a helpful option for patients who cannot undergo skin testing. Allergy testing is also helpful for patients with asthma, since allergies are a common asthma trigger.
Effective Allergy Treatment Options
Once Dr. Grewal identifies your triggers, he will discuss treatment options tailored to your needs, including:
- Allergen avoidance strategies
- Antihistamine medications
- Nasal sprays
- Emergency epinephrine injectors for serious allergies
- Immunotherapy (allergy shots)
Immunotherapy is a highly effective long-term treatment that introduces very small, gradually increasing amounts of an allergen into your body. Over time, your immune system becomes less sensitive and your symptoms improve. For sudden allergy flare-ups, we also offer same-day walk-in care.
Allergy Testing FAQs
How is allergy testing performed?
We offer in-office skin scratch tests, which place tiny amounts of allergens on the skin to check for reactions, as well as blood tests that measure allergy-related antibodies.
Does allergy testing hurt?
Skin scratch testing causes only mild, brief discomfort, similar to a light scratch. Any itching or redness usually fades within a short time.
How long does allergy testing take?
Skin testing typically takes less than an hour, including time to observe your skin for reactions. Blood test results usually take a few days.
Should I stop taking allergy medication before testing?
Antihistamines can interfere with skin test results, so you may need to stop them for several days beforehand. Our team will give you specific instructions when you schedule.
Can children have allergy testing?
Yes. Allergy testing is safe for children, and identifying allergies early can help prevent ongoing symptoms and asthma flare-ups.
What is immunotherapy?
Immunotherapy, or allergy shots, involves a series of injections with small, gradually increasing doses of an allergen to help your immune system become less sensitive over time.
Can I walk in for allergy symptoms?
Yes. You are welcome to walk in during business hours for allergy flare-ups, or you can book an appointment online or by phone.
