What Is an Allergy?

What is an Allergy?

A man is coughing into his elbow.

An allergy is a medical condition in which the immune system reacts abnormally to substances that are typically harmless to most people. These substances, called allergens, can range from common triggers like pollen and pet dander to foods, medications, and insect bites.

 

To learn more about how the body reacts to allergens, when allergies can develop, how allergies are diagnosed, what the most common symptoms/reactions are, and how to treat allergies, read on!


How Does the Body React to Allergens?

When an individual with an allergy is exposed to an allergen, their immune system identifies it as a threat and releases histamine and other chemicals, which cause the symptoms of an allergic reaction. These symptoms can range from mild to severe and can include itching and rashes, runny nose and watery eyes, wheezing and coughing, and in severe cases, anaphylaxis, a life-threatening reaction that can cause swelling, difficulty breathing, and a drop in blood pressure.


When Can Allergies Develop?

Allergies can develop at any age and can be genetic, meaning they can be passed down from parents to children. Some people may also have multiple allergies or experience a cross-reaction, where they have an allergic response to more than one substance.


How Are Allergies Diagnosed?

The diagnosis of allergies typically involves a combination of medical history, physical examination, and various tests, such as skin prick tests, blood tests, and elimination diets. Treatment options vary based on the type and severity of the allergy and may include multiple options to help manage it.


What Are the Most Common Symptoms of Allergies/Allergic Reactions?

The most common allergic reactions include the following:


●     Rhinitis (hay fever): nasal congestion, runny nose, sneezing, and itching

●     Conjunctivitis (eye allergy): red, itchy, and watery eyes

●     Skin reactions: itching, redness, and swelling

●     Asthma: wheezing, coughing, and shortness of breath

●     Anaphylaxis: a severe and potentially life-threatening reaction that can cause swelling, difficulty breathing, and a drop in blood pressure


How Are Allergies Treated?

Managing allergy symptoms starts with avoiding or reducing exposure to known allergens. This can include measures such as:


●     Staying indoors when pollen levels are high

●     Keeping windows and doors closed to reduce exposure to outdoor allergens

●     Vacuuming regularly and using air filters to remove dust and dander from the home

●     Washing bedding in hot water to remove dust mites

●     Keeping pets out of the bedroom and off upholstered furniture

●     Wearing a mask when performing activities that generate dust, such as gardening or mowing the lawn

●     Avoiding certain foods if food allergies are suspected

 

In addition to allergen avoidance, over-the-counter medications such as antihistamines, decongestants, and nasal sprays can help relieve symptoms. If these medications are not effective, a healthcare provider may prescribe stronger medications such as corticosteroids or immunotherapy. Immunotherapy, also known as allergy shots, works by gradually exposing an individual to increasing amounts of an allergen to help build up a tolerance over time. This treatment can be effective for individuals with persistent or severe allergies and is typically administered by an allergist.


What if I Don’t Want to Take Over-The-Counter Medications?

Another effective way to manage allergy symptoms is to use home remedies. For example, you can try the following:

●     Using a saline nasal spray to flush out allergens

●     Applying a cold compress to reduce swelling and itching

●     Taking a warm bath or using a humidifier to relieve congestion

●     Drinking plenty of fluids to thin mucus and relieve symptoms


When Should I Go See a Doctor?

If you have a severe or life-threatening reaction, suspect an allergy, or believe you may have an allergy, you should see a doctor right away. A plan for managing your allergies and lowering your risk of future reactions can be created with the assistance of an allergist. The amazing team at Bayou Bend Health System can help!

A Beginner’s Guide to Understanding Your Blood Tests

August 28, 2026
Blood tests are common tools healthcare providers use to understand what is happening inside the body. Whether part of a routine physical, a preventive visit, or an evaluation for a specific concern, blood tests give valuable information about overall health. Seeing a list of numbers and medical terms on a lab report can feel overwhelming, but understanding the basics helps patients feel more informed. Bayou Bend Health System offers comprehensive healthcare services and helps patients understand their lab results and what they may mean for their wellness. Why Are Blood Tests Important? Blood tests can provide healthcare providers with information that may not be apparent during a physical examination. They can help monitor overall health, identify likely concerns, and monitor changes over time. Depending on the type of test ordered, blood work may provide information about: • Blood cell counts • Blood sugar levels • Cholesterol and heart health • Kidney and liver function • Electrolyte levels • Nutritional deficiencies • Inflammation or infection • Other indicators of overall health Routine blood tests help healthcare providers spot changes early, so patients can talk over next steps. Understanding a Complete Blood Count (CBC) A complete blood count, or CBC, is a frequently ordered blood test. It measures different types of blood cells and provides information about several aspects of health. A CBC may include measurements of: • Red blood cells that disperse oxygen throughout the body • White blood cells, that fight unwanted infections from spreading • Hemoglobin, a protein that carries oxygen • Hematocrit, which measures the proportion of blood made up of red blood cells • Platelets, which help with blood clotting A healthcare provider explains what individual results mean based on a patient’s health history and other findings. What Do Blood Sugar Tests Tell You? Blood glucose testing measures blood sugar. These tests screen for or monitor blood sugar conditions, including diabetes. Common blood sugar tests include fasting blood glucose and hemoglobin A1C. An A1C test estimates average blood sugar levels over the previous several months. Understanding blood sugar results helps patients and providers discuss nutrition, physical activity, medications, and other factors supporting healthy glucose levels. Understanding Cholesterol and Lipid Tests Cholesterol testing is a common part of preventive healthcare. A lipid panel measures overall cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. These numbers help healthcare providers evaluate cardiovascular risk alongside elements such as age, blood pressure, family history, lifestyle, and existing health conditions. A single cholesterol number doesn't tell the whole story. Your provider can help interpret your results within the context of your overall health. What Does It Mean When a Result Is “High” or “Low”? Seeing a result marked high or low can cause concern. However, a result outside the reference range does not automatically mean something is wrong. Reference ranges can vary by laboratory, test, and individual factors. Providers consider the complete picture—including symptoms, medical history, medications, and other test results—when interpreting laboratory findings. Patients should avoid self-diagnosing based on individual numbers. Instead, discuss questions or unexpected results with a qualified healthcare professional. Take an Active Role in Your Health Understanding your blood tests can make healthcare visits less confusing and help you have more productive conversations with your provider. If you receive lab results you don't understand, ask questions and ask for an explanation of what the numbers mean for your health. At Bayou Bend Health System, our healthcare professionals are committed to helping patients understand their health and help make informed decisions about their care. Whether you need routine blood work, preventive care, or help understanding your lab results, our team is here to help.

Back-to-School Prep: Why Physicals and Vaccines Matter Before the First Bell

July 29, 2026
As summer ends, families prepare for a successful school year with new supplies, updated schedules, and fresh goals. While shopping for backpacks and school clothes is important, one essential part of back-to-school preparation is ensuring children are healthy and ready to learn. Routine physicals, recommended vaccines, and preventive healthcare visits help students start the year feeling their best. Bayou Bend Health System provides comprehensive pediatric and family healthcare services to support children and families throughout the school year. Schedule a Back-to-School Physical Exam A yearly physical exam is important to preserve a child’s overall health. These visits let healthcare providers monitor growth, development, and wellness while identifying concerns before they become bigger issues . During a back-to-school physical, providers may review: Height, weight, and growth patterns Blood pressure and vital signs Vision and hearing health Nutrition and physical activity habits Sleep routines and overall wellness Medical history and current health concerns These appointments also give families a chance to ask questions about their child’s health, discuss changes, and get guidance to support healthy habits throughout the school year. Stay Up to Date on Recommended Vaccines Vaccinations are a key part of back-to-school preparation. Immunizations protect children from preventable diseases and help create a healthier school environment by reducing the spread of infections among students, teachers, and families. Depending on age and vaccination history, children may need routine immunizations or booster shots before returning to class. Medical professionals can review records, identify missing vaccines, and help families create a plan to keep children protected. Common school-required or recommended vaccines may include protection against: Tetanus, diphtheria, and pertussis (Tdap) Measles, mumps, and rubella (MMR) Chickenpox (varicella) Meningococcal disease Influenza (flu) Other recommended childhood illnesses Keeping immunizations current helps students attend school safely and confidently. Prepare for Sports and Physical Activities For children in sports, physical activity programs, or extracurricular activities, a sports physical may be required before participation. These evaluations determine if a child is ready for physical activity and let providers identify likely concerns related to heart health, injuries, or other conditions. A sports physical can also be a great time to discuss injury prevention, proper nutrition, hydration, and safe exercise habits. Address Vision, Hearing, and Other Health Concerns Children rely on healthy vision and hearing to participate fully in class. Difficulty seeing the board, hearing instructions, or focusing on lessons can affect educational performance and confidence. A physical exam can help identify concerns early and connect families with additional care when needed. Dealing with these issues before the school year begins allows students to focus on learning free of unnecessary barriers. Support Your Child’s Mental and Emotional Wellness Back-to-school preparation is not only about physical health. Returning to school brings excitement, new challenges, and changes in routines. Healthcare visits provide a chance to discuss mental well-being, stress, anxiety, sleep habits, and other concerns that may affect a child’s success. Candid talks about mental health help children feel cared for as they manage academic and social experiences throughout the year. Start the School Year with Confidence A healthy start can have a notable effect on a child’s school experience. Scheduling physicals, updating vaccines, and handling health concerns before the first day of class help children enter the school year prepared for success. At Bayou Bend Health System, our team is focused on providing compassionate, comprehensive care for children and families. If your child needs a routine checkup, immunizations, sports clearance, or guidance toward maintaining good health, our providers are here to help. Schedule your child’s back-to-school visit today by calling 337-907-6764 and take an important move toward a healthy and successful school year.
