Allergies have a wide variety of symptoms depending on what the allergen is and how your body reacts to it. Some responses are more common than others, but it is important to be aware of all possible symptoms in order to treat it effectively. Here, NJ ENT identifies allergy symptoms to keep note of.

What Causes Allergies?

Allergies occur when your immune system reacts to a substance that is normally harmless. These substances, known as allergens, can be found in places from pollen to latex. An allergic person’s immune system mistakenly identifies allergens as a threat. Then, the immune system releases chemicals, causing allergy symptoms. Several factors contribute to your likelihood of developing allergies, including genetics, exposure to allergens, and more.

Allergies can be triggered by many different things, which can be ordered into categories. The main categories are:

  • Pollen: Seasonal changes can cause an influx of pollen, causing seasonal allergies.
  • Dust and Dander: Dust and other small particles can cause allergic reactions. This is especially true for pet dander, most commonly cats.
  • Foods: There are many kinds of foods that trigger allergic symptoms. Common ones include peanuts and shellfish.
  • Skin Contact: Poison ivy, sumac, and latex are common allergies that are triggered by coming into contact with the skin.
  • Medications: Some people are allergic to medications, such as penicillin. Your doctor will work with you to find a medication that works for you.

Identifying Allergy Symptoms

Allergy symptoms can manifest in different ways, and their severity ranges from mild to severe. Depending on the trigger, symptoms can vary. Allergy symptoms include:

Seasonal Allergies: Breathing pollenated air can trigger allergies. This often occurs during certain times of the year, such as spring which has more tree pollen. It can also be associated with certain kinds of plants. Some places are known for triggering allergies more than others because of the plant life and environment specific to that location.

Dust and Dander: Pets with fur or feathers often have dander associated with them. Some people are allergic to the dander of certain animals, causing a reaction when coming into contact with them. Pets that shed their fur will trigger allergy symptoms more often and more intensely. These triggers have very similar symptoms to seasonal allergies.

Combined with asthma, symptoms can intensify. Here are the symptoms of seasonal allergies, dust, and dander:

  • Sneezing and Runny Nose
  • Itchy or Watery Eyes
  • Coughing and Wheezing
  • Difficulty Breathing

Foods: There are many foods that cause allergic reactions. Common foods people are allergic to are peanuts, tree nuts, milk, soy, shellfish, fish, eggs, and wheat. These foods are associated with GI issues. Symptoms are acute and can range in severity. Here are symptoms of food allergies:

  • Nausea
  • Vomiting
  • Diarrhea
  • Abdominal pain
  • Swelling of the tongue and throat
  • Difficulty breathing
  • Dizziness

Skin Contact: Some allergy symptoms are activated by contact with the skin. These triggers are most commonly plants, such as poison ivy, and latex. Latex is found in certain products such as latex gloves, balloons, rubber bands, and more. Here are some common allergy symptoms that affect the skin:

  • Hives
  • Eczema
  • Itchiness
  • Contact Dermatitis

Anaphylaxis: This is a severe allergic reaction that can be fatal, however it can be treated by doctors so it is important to act quickly. Symptoms can develop within seconds, and include:

  • Swelling of the throat
  • Difficulty breathing
  • Dizziness
  • Rapid heart rate
  • Nausea/Vomiting

Allergy Treatment Options

There are a wide range of effective allergy treatment options. A specific plan will be put in place by your doctor, specific to your needs. Some allergy treatment options include allergy testing, allergy medications, allergy immunotherapy, and lifestyle modifications. These are all dependent on your specific allergy, your current lifestyle, and your goals.

Allergy Symptoms FAQs

What should I do if I suspect I have a new or undiagnosed allergy?2024-08-26T13:33:41-05:00

It is recommended you keep a journal of symptoms and potential triggers and schedule an appointment with your healthcare provider. You should also avoid your suspected allergy trigger whenever possible.

What’s the difference between allergies and a cold?2024-08-26T13:33:26-05:00

While they have similar symptoms, they do not have the same cause. Allergies are often seasonal, not accompanied by a fever, and due to exposure to the allergen. Colds are often associated with fevers and body aches. Colds subside after 7 to 10 days.

Can allergies change over time?2024-08-26T13:33:14-05:00

Yes, some may outgrow certain allergies and others may develop new allergies later in life.

After seeing a previous ENT for chronic sinusitis, I realized after many months that it was not helping me being on antibiotics all that time. After deciding to move on I found Dr Reddy. I was 100% block on left sinus and partially blocked on right sinus, he suggested to me a balloon sinuplasty procedure that he does in office compared to doing a full surgery. Being that I have 3 autoimmune diseases I was hesitant to have the full surgery. So I decided to do it and it was a short procedure and painless. Sinuplasty is less invasive and quicker recovery than surgery. Its been almost a year later and I’ve been feeling great. I had no issues this spring with allergies and couldn’t be any happier. I highly recommend Dr Reddy and his staff!

Dr. Smith is very thorough during my examination. He explained the recommended approach to solving my sinus and allergy issues. I will be returning for a follow-up. One of the best ENT doctors I have been to. I highly recommend him.

I have been having some issues in my throat for about 6-7 months straight. I kept having a feeling like their was a lump feeling in my throat. I have been to three different ENT's in the Mercer County Area. They were all horrible until I met Dr. Undavia. He took the time to listen to the symptoms I was experiencing, and performed test. He made me feel comfortable and he was extremely knowledgeable. I finally found out what was wrong. What I was experiencing was allergy related, while other doctors were telling me that it was nothing and it was in my head. I am extremely grateful for Dr. Undavia. I would DEFINITELY recommend him. He is an amazing doctor!

I could not be happier with my experience with Dr. Nishant Reddy. I had been suffering from a loss of smell for years and constant nasal congestion. Dr. Reddy was very knowledgeable and thorough, ultimately determining that nasal polyps/allergies were causing my issues. He discussed the options we could take that included first using medications to resolve my symptoms. Subsequently, I decided to have sinus surgery. Dr. Reddy performed the surgery and it was a complete success. He used the latest techniques and post surgery I was able to breath through both nostrils for the first time in years as well as regain my sense of smell. Dr. Reddy has since continued to work with me to come up with a plan to manage my allergies by using sprays and rinses to keep my sinuses clear especially during allergy season. Every time I go for an appointment with Dr. Reddy, I feel like I am in very good hands.
