Mold allergies are easily treatable when properly diagnosed, so it is important for individuals who suspect their symptoms may be related to mold to consult with an allergy specialist or a physician to determine an appropriate course of treatment. Taking steps such as repairing water leaks and installing dehumidifiers in the home can also help to hinder mold growth and relieve mold allergy symptoms. Understanding what causes mold allergies and taking preventative measures to avoid exposure are essential in managing symptoms.
Itching Eyes
Itching eyes are a common allergic symptom that can develop following exposure to mold spores, pet dander and seasonal pollens. Individuals who experience itching eyes during wet or humid weather or when moisture levels are high inside the home may be suffering from mold allergy symptoms.
Stuffy Nose & Post Nasal Drip
Nasal congestion is a common mold allergy symptom that is often triggered after periods of wet weather or when an individual is exposed to mold spores in the home. When nasal stuffiness occurs, it is often accompanied by postnasal drip, a condition in which nasal secretions run down the back of the throat. Additional symptoms of postnasal drip include bad breath and coughing.
Itching Throat
Individuals with mold allergies may also experience an itching sensation in the throat. Itching throat symptoms are typically caused by postnasal drip, but can also be a symptom of a serious allergic reaction that can lead to throat swelling if left untreated. It is important for sufferers to seek medical attention if itching throat symptoms are present to ensure prompt treatment.
Sinus Headaches
Mold spores can cause the sinuses to become congested, which in turn can trigger sinus headaches in individuals with mold allergies. Sinus headaches cause pain and pressure in the forehead and sinus cavities. In certain cases, sinus pressure can also cause tooth and ear pain. Sinus headaches tend to worsen when lying down.
Exacerbated Asthma Symptoms
Individuals with mold allergies who also suffer from asthma may experience exacerbated asthma symptoms when exposed to mold. Asthma symptoms include chest tightness, wheezing and coughing. Anyone experiencing a severe asthma attack following possible mold exposure should seek immediate medical attention.
Long & Short Term Effects of Mold
The type and severity of health effects that result from mold exposure is widely variable among different locations, from person to person and over time. Although difficult to predict, exposure to molds growing indoors is most often associated with the following allergy symptoms:
Nasal and sinus congestion
Cough/sore throat
Chest tightness
Dyspnea (breathing difficulty)
Asthma (or exacerbation of it)
Epistaxis (nosebleed)
Upper respiratory tract infections
Headache
Skin and eye irritation
Long-term exposure to indoor molds is certainly unhealthy to anyone, but some groups will develop more severe symptoms sooner than others, including:
Infants and children
Elderly people
Individuals with respiratory conditions, allergies and/or asthma
Some indoor molds are capable of producing extremely potent toxins (mycotoxins) that are lipid-soluble and readily absorbed by the intestinal lining, airways, and skin. These agents, usually contained in the fungal spores, have toxic effects ranging from short-term irritation to immunosuppression and cancer.
More severe symptoms that could result from continuous human exposure to indoor mycotoxigenic molds include:
Cancer (aflatoxin best characterized as potential human carcinogen)
Hypersensitivity pneumonitis/pulmonary fibrosis
Pulmonary injury/hemosiderosis (bleeding)
Neurotoxicity
Hematologic and immunologic disorders
Hepatic, endocrine and/or renal toxicities
Pregnancy, gastrointestinal and/or cardiac conditions
It is important to notice that the clinical relevance of mycotoxins under realistic airborne exposure levels is not fully established. Further, some or much of the supporting evidence for these other health effects is based on case studies rather than controlled studies, studies that have not yet been reproduced or involve symptoms that are subjective.
