Symptoms Of Mold Allergies

How To Make Patchouli Salve

Mold allergy causes the same signs and symptoms that happen in other types of upper respiratory allergies. Mold allergy symptoms might include the following:

  • Sneezing
  • Postnasal drip and cough
  • Itchy nose, throat and eyes

Mold allergy symptoms differ among people and range from mild to severe. You might have symptoms year-round, or symptoms which flare up only during certain times of the year. You may notice symptoms when the weather is damp, or when you are outside or inside spaces with high concentrations of mold.

If you have asthma or a mold allergy, the symptoms of asthma might be triggered by exposure to mold spores. In some people, exposure to certain molds may cause a severe asthma attack. Signs and symptoms of asthma include the following:

  • Coughing
  • Shortness of breath

Where Do Molds Grow

Molds can be found wherever there is moisture, oxygen, and a source of the few other chemicals they need. In the fall they grow on rotting logs and fallen leaves, especially in moist, shady areas.

In gardens, they can be found in compost piles and on certain grasses and weeds. Some molds attach to grains such as wheat, oats, barley, and corn, making arms, grain bins, and silos likely places to find molds.

Hot spots of mold growth in the home include damp basements and closets, bathrooms , places where fresh food is stored, refrigerator drip trays, house plants, air conditioners, humidifiers, garbage pails, mattresses, upholstered furniture, and old foam rubber pillows.

Bakeries, breweries, barns, dairies, and greenhouses. In addition, anytime there is a water leak, it is important that as soon as the source of the leak is repaired, the surrounding areas be inspected and cleaned if necessary for mold growth.

Risk Factors For Mold Allergies

Several factors may make a person more likely to develop a mold allergy, or worsen their existing mold allergy symptoms. Some of these factors include the following:

  • A Family History of Allergies: If asthma and allergies run in a person’s family, they are more likely to develop a mold allergy.
  • Occupational Exposure: Occupations where mold exposure may be high include dairy work, farming, baking, logging, greenhouse work, carpentry, furniture repair and winemaking.
  • Living or Working in a Building Exposed to Excess Moisture: Examples include water seepage during flood damage or rainstorms, or leaky pipes. At some point, almost every building has some kind of excessive moisture, which may allow mold to flourish.
  • Living in a Home with Poor Ventilation: Tight door seals and window seals may trap moisture indoors and prevent appropriate ventilation, creating conditions that are ideal for the growth of molds. Damp areas such as kitchens, basements and bathrooms are most vulnerable.
  • A Home with High Humidity: If a person’s indoor humidity is greater than sixty-percent, they might have increased exposure to mold in their home. Mold can grow almost anywhere if the conditions are right in basements, on soap-coated grout, behind walls in framing, in carpet pads or carpeting, as well as on damp surfaces. Exposure to high levels of household mold might trigger mold allergy symptoms.

How To Diagnose A Mold Allergy

To test for a mold allergy, the doctor will take a comprehensive medical history and ask you about your symptoms and when they occur. Mold allergy tests include:

  • Skin prick tests Droplets of mold allergens are placed on the skin surface with tiny punctures. Raised bumps strongly indicate an allergy to that substance.
  • Blood tests Chemical testing detects Immunoglobulin E antibodies circulating in your blood that are directed at specific allergens. Lab results may take days. A blood sample is sent to a medical laboratory, where it can be tested for evidence of sensitivity to specific types of mold.

The doctor will put all the evidence together test results, your personal and family health history, home and work environments, activities that might expose you to allergens, a physical exam of your eyes, ears, nose and lungs before reaching a diagnosis.

Mold is a fungi that releases microscopic airborne spores. Some molds are commonly found in households and may release spores and other particles into the air. If you have a mold allergy, it means that your body is sensitive to molds. When you breathe in airborne mold particles, your immune system may react and start trying to fight off the mold. The antibodies produced, including histamine, when your body tries to fight off the mold can cause hay fever-type symptoms, including:

  • Sneezing
  • Runny nose or nasal congestion
  • Throat irritation
  • Skin rash

An allergic reaction to mold may happen immediately after exposure, or it may be delayed. Mold allergy symptoms and their severity will vary from person to person, depending on the type and severity of his or her allergy. For example, some people only experience mold allergy symptoms during certain weather conditions. Additionally, outdoor molds may only cause allergic reactions during certain seasons, but indoor mold, such as black mold, can cause reactions all year round.

Note: Where you live may affect your exposure to outdoor mold.

How To Avoid Mold Exposure

To reduce mold growth in your home, take into consideration these tips:

  • Eliminate sources of moisture in basements, such as pipeline leakages or groundwater seepage.
  • Use a dehumidifier in any type of area of your house that smells moldy or damp. Maintain your humidity levels below 50%. Bear in mind to clean the collection container as well as condensation coils routinely.
  • Make use of an air conditioner and consider mounting central air conditioning with a high-efficiency particle air filter add-on. The HEPA filter can trap mold spores from outdoor air before theyre circulated inside your house.
  • Clean filters on your heating system as well as air conditioners regularly. Have forced-air heating ducts examined as well as, if required, cleansed.
  • Make sure all bathrooms are properly vented, and run the ventilation follower during a shower or bathroom as well as promptly after to dry the air. If you dont have an airflow follower, open a window or door while youre showering or bathing.
  • Promote groundwater drain away from your house by eliminating fallen leaves as well as vegetation from around the structure and cleaning gutter frequently. Make certain the ground inclines away from the foundation.
  • Throw away or reuse old publications and newspapers. If left in moist places, such as cells, they can rapidly become moldy.
  • What Are The Symptoms Of A Mold Allergy

    The symptoms of mold allergy are very similar to the symptoms of other allergies, such as sneezing, itching, runny nose, congestion and dry, scaling skin.

    • Outdoor molds may cause allergy symptoms in summer and fall
    • Indoor molds may cause allergy symptoms year-round

    Mold spores get into your nose and cause hay fever symptoms. They also can reach the lungs and trigger asthma. A chemical released by allergy cells in the nose and or lungs causes the symptoms. Sometimes the reaction happens right away. Sometimes a mold allergy can cause delayed symptoms, leading to nasal congestion or worsening asthma over time. Symptoms often get worse in a damp or moldy room like a basement. This may mean you have a mold allergy.

    Rarely, some patients can have a more serious illness called allergic bronchopulmonary aspergillosis. In this condition, there is both an allergic and an inflammatory response to the mold. Symptoms may include severe wheezing, coughing and shortness of breath, much like asthma.
