“I had my first appointment with Dr. Cajigal. She’s wonderful. A different doctor had said there wasn’t much I could do for my allergies, except maybe move out of state. I was desperate and came to this doctor for help. She listened and was very thorough in her diagnosing my problems. I’m not better yet but I’m very pleased with how this appointment went and I’m optimistic about my health!”

When is Allergy Season in St. Louis, Missouri?

Depending on what you’re allergic to, your seasonal allergies may peak in the spring, in the fall, or affect you year-round.

Spring Allergy Season

Spring allergy season in St. Louis typically starts in March and extends into mid-July. Pollinating trees usually mark the start of spring allergy season and continue releasing pollen well into May. Common culprits of seasonal allergies in St. Louis include oak trees, cedar trees, hickory trees, walnut trees, and ash trees. A number of other less common trees are also responsible for seasonal allergies in St. Louis, including aspen, alder, ash, birch, beech, box elder, cottonwood, elm, mountain elder, mulberry, olive, poplar, pecan, and willow trees.

The St. Louis spring allergy season is extended by pollinating grass, which typically starts in May and ends in mid-July.

Fall Allergy Season

Fall allergy season starts with the bloom of ragweed in August and usually peaks in mid-September. Ragweed is prevalent in Missouri, and is the primary cause of seasonal allergies from late August through the first frost of early winter. Most individuals that experience allergy symptoms in the fall are allergic to ragweed. Other allergenic plants that trigger fall allergies include burning bush, cocklebur, lamb’s-quarters, mugwort, pigweed, russian thistle, sagebrush, and tumbleweed.

Seasonal Allergy Variation

Several factors can influence the onset, duration, and severity of seasonal allergy symptoms.

  • Mold levels can peak during specific weather patterns, sometimes imitating seasonal allergies. Mold grows quickly during rainy periods, and also during hot and humid periods.
  • Pollen levels are usually highest in the morning, and are amplified by wind and warm weather.
  • Mild winter temperatures can cause plants to pollinate early, making spring allergy season start earlier than March.
  • A rainy spring can promote rapid plant growth and high pollen levels that persist into the fall.

Seasonal Allergy Symptoms

Seasonal allergies, also called seasonal allergic rhinitis or hay fever, cause symptoms such as runny nose, itchy eyes, sneezing, and cough. Your symptoms may vary depending on what you’re allergic to, and could could include any of the following:

  • Coughing
  • Frequent sneezing
  • Wheezing
  • Runny nose
  • Congestion
  • Sinus pressure
  • Scratchy throat
  • Excess saliva
  • Itchy, stinging, watery eyes
  • Fatigue
  • Trouble Sleeping
  • Asthma symptoms

Seasonal Allergy Diagnosis

Seasonal allergy symptoms tend to be relatively consistent from allergen to allergen. In other words, an allergy to oak tree pollen can look a lot like a ragweed allergy, but you’re not necessarily allergic to both if you’re allergic to one of them. Understanding exactly what you’re allergic to can make it much easier to navigate seasonal allergies in St. Louis and know what you should (and should not!) be avoiding. This is where allergy testing comes in. Dr. Cajigal can help you determine if your symptoms are caused by allergies and pinpoint what you’re allergic to so you can find relief.

Seasonal allergy diagnosis starts with a thorough medical history, and usually involves skin or blood tests to determine your specific allergic triggers.

Seasonal Allergy Treatment

Once you’re aware of what’s causing your allergies, there are steps you can take to minimize exposure to allergens, effectively manage allergic reactions if they occur, and prevent certain allergic reactions altogether.

Limit Your Exposure to Airborne Allergens

These tips can help you minimize your exposure to airborne allergens during allergy season:

  • Check your local pollen counts whenever you check the weather
  • Limit outdoor activities during times of high pollen counts
  • Wear sunglasses and a wide brimmed hat to reduce pollen exposure when outdoors
  • Change clothes as soon as you get home if you’ve spent a lot of time outdoors

When you visit us at St. Louis Family Allergy, Dr. Cajigal will have additional recommendations for you based on your unique case.

Allergy-Proof Your Home

These tips can help you minimize exposure to allergens in your home:

  • Keep windows closed during high pollen and mold seasons
  • Steam clean carpets or remove carpets altogether
  • Avoid air drying laundry outside
  • Keep pets out of the bedroom to reduce pet dander in your bedding
  • Vacuum with a HEPA filter to reduce dust in your home
  • Wash your bed linens and pillowcases in hot water and detergent frequently to reduce allergens
  • Use dust mite proof covers for pillows, comforters, duvets, mattresses and box springs
  • Men should shave frequently to prevent pollen from gathering in their facial hair

Medications for Seasonal Allergies

There are a number of over-the-counter and prescription medications that can help relieve seasonal allergy symptoms. Be sure to discuss any medications with your allergist prior to using them. Medications to relieve seasonal allergic rhinitis, for example, are most effective if you start taking them before pollen is in the air, prior to allergy symptoms developing.

Medications include:

  • Antihistamines
  • Decongestants
  • Nasal corticosteroids (nasal spray)
  • Leukotriene receptor antagonists
  • Cromolyn sodium

Allergy Shots for Seasonal Allergies

Allergy shots are also an option if you’re looking for long-term, ongoing symptom relief from seasonal allergies.

We hope you’ve found this information helpful. Get in touch with us at St. Louis Family Allergy to learn more about seasonal allergies and how to most effectively manage them! We’re looking forward to your visit.

"Dr. Cajigal was friendly, professional, and informative. She took the time to explain the tests and what was going on with my allergies. She is so knowledgeable and really cared about how I was feeling. I would highly recommend this practice if you suffer from allergies and asthma."

- Sue D, July 2020

“Dr Cajigal is a great listener. She trusts her patients instead of treating them as if they are not the experts of their own bodies. I really appreciate that (many doctors do not have that quality). She also immediately treats the symptoms instead of waiting to see if things clear. I use her for my children and myself. We have never left her office feeling as if it was a waste of time.”
