Weed allergies result in hay fever (upper respiratory problems) because your immune system reacts to the pollen. Depending on where you live in the United States, weed pollen allergy season is from spring (April or May) through fall (October or November), according to Allergyescape.com.
The acacia shrub, which grows primarily in Southern California, produces an allergenic pollen in springtime that can induce hay fever and asthma. People can also have allergic reactions to gum acacia, made from sap and commonly used as an additive in foods and beverages nationwide.
Some people experience an intolerance or allergic reaction to red dyes used in food, drugs and cosmetics. Reactions range from mild to severe. Red dye is made from either cochineal or carmine additives and has been recognized as a known allergen by the FDA.
Conn's allergy, or Conn's syndrome, is a condition that can cause high blood pressure. It's identification is important because, unlike other causes of hypertension, Conn's syndrome can be cured if it's uncovered.
Corn is not considered one of the "big eight" allergens--eggs, milk, soy, fish, peanuts, tree nuts, shellfish, wheat--but the incidence of corn allergy is increasing. This may be a result of increased consumption of processed foods by young children, many of which contain corn products. Ingesting corn, touching corn or products containing corn, or breathing in corn particles or pollen, can trigger symptoms of corn allergies. In most cases, symptoms are manageable, but for some people, exposure to corn can trigger a potentially fatal anaphylactic reaction.
For some, allergies can seem to pop up out of nowhere, but for others, reactions appear like clockwork. Allergic responses occur when a specific substance is inhaled or ingested and the body reacts to it. Anyone with allergies has their own unique set of allergens that affect them along with their own set of symptoms. Knowing the root of your allergies, including identifying the symptoms, can help in treating your condition.
