Fall Allergies in St. Louis, Missouri
“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 Dr. Cajigal for help. She listened and was very thorough in diagnosing my problems. ”

About Fall Allergies in St. Louis
Fall Allergies Overview
Allergies are often associated with spring and summer when trees, grass, and other vegetation are at the peak of their annual pollination cycles. However, certain pollens become more prevalent during the fall than spring and summer.
Fall allergy season in St. Louis starts with the bloom of ragweed in August and usually peaks in mid-September. Burning bush, cocklebur, lamb’s-quarters, mugwort, pigweed, russian thistle, sagebrush, and tumbleweed pollen are also prevalent in the Missouri fall time, and remain active until the first frost of winter.
In addition to fall vegetation, decaying grass and leaves also contribute to an increase in mold spores. Mold grows quickly during rainy periods, and also during hot and humid periods. This makes mold particularly prevalent in the midwestern fall, where weather can quickly shift between warm and humid, and damp and cool.
Perennial (year-round) allergies like indoor mold, pets, dust, and dust mites can also get worse in the Missouri fall due to the changing weather, and because individuals tend to spend more time indoors as the weather gets cooler.

Fall Allergies vs Spring Allergies
Many allergy sufferers are curious about the differences between fall allergies vs spring allergies. Allergy symptoms are similar between the two seasons, but what causes fall allergies vs spring allergies can vary significantly. Fall allergies are more often caused by ragweed, whereas spring allergies are typically caused by pollinating trees and grass. Mold can be prevalent during both fall and spring. Depending on what you’re allergic to, you might experience worse symptoms during the fall vs the spring.

Testing for Fall Allergies
A fall allergy diagnosis can usually be confirmed with a simple skin prick test, but Dr. Cajigal may order intradermal testing or blood testing as needed if a skin prick test is inconclusive or cannot be performed.
