What are the signs of mold allergies

Inhalation exposure to mold indoors can cause health effects in some people. Molds produce:

  1. Allergens (substances that can cause allergic reactions)
  2. Irritants
  3. Potentially toxic substances or chemicals (mycotoxins)

Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Mold does not own to be alive to cause an allergic reaction.

Dead or alive, mold can cause allergic reactions in some people.

Allergic Reactions, Asthma Attacks, Irritant Effects

Allergic reactions to mold are common and can be immediate or delayed. Repeated or single exposure to mold, mold spores, or mold fragments may cause non-sensitive individuals to become sensitive to mold, and repeated exposure has the potential to increase sensitivity. Allergic responses include hay fever-like symptoms such as:

  1. Sneezing
  2. Runny nose
  3. Red eyes
  4. Headache
  5. Skin rash (dermatitis)

Molds can cause asthma attacks in people with asthma who are allergic to mold.

In addition, whether or not individuals are allergic to mold, molds can irritate:

  1. Skin
  2. Nose
  3. Throat
  4. Eyes
  5. Lungs

Other Health Effects

Breathing in mold may also cause hypersensitivity pneumonitis, an unusual disease that resembles bacterial pneumonia. In addition, mold exposure may result in opportunistic infections in persons whose immune systems are weakened or suppressed.

When mold grows indoors, the occupants of a building may start to report odors and a variety of symptoms including:

  1. Difficulty breathing
  2. Skin irritation
  3. Allergic reactions
  4. Headaches
  5. Aggravated asthma symptoms

These and other symptoms may be associated with exposure to mold.

But every of these symptoms may be caused by other exposures or conditions unrelated to mold growth. Therefore, it is significant not to assume that, whenever any of these symptoms occurs, mold is the cause.

For more detailed information on mold and its health effects, consult:

Damp Buildings

Although mold is frequently found in damp buildings, it is not the only potential contaminant — biological contaminants other than mold, and non-biological contaminants are often present and may also cause health effects.

Damp buildings may attract rodents and other pests. Damp or wet building components and furnishings may release chemicals indoors.

Potential contaminants in damp or wet buildings include:

  1. Dust mites
  2. Cockroaches and other pests
  3. Bacteria
  4. Chemicals emitted by damp building materials and furnishings

For more information on damp buildings and health effects, see the Institute of Medicine Report, Damp Indoor Spaces and Health, published by The National Academies Press.

Different Types of Mold

Allergenic Molds. Allergenic molds are on the low finish of the harm scale.

They only cause problems for those with asthma and a predisposed allergy to the specific mold. Children are more likely to own mold allergies than adults.

Pathogenic Molds.

What are the signs of mold allergies

Pathogenic molds will cause some infection. This is a large problem for those with a suppressed immune system. An acute response resembling bacterial pneumonia is commonly found with those exposed to these types of mold.

Toxigenic Molds. As the name implies, these molds produce mycotoxins that can cause serious health effects. They own been tied to immunosuppression and cancer. The toxic chemicals found in these types of molds can be absorbed into the body when one inhales them, eats them, or even touches them.

Mold Allergy

What Are the Symptoms of a Mold Allergy?

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

  1. Outdoor molds may cause allergy symptoms in summer and drop (or year-round in some climates)
  2. 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 correct 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 love a basement. This may mean you own a mold allergy.

Rarely, some patients can own 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 love asthma.

Food fungi, love mushrooms, dried fruit, or foods containing yeast, vinegar or soy sauce, generally don’t cause allergy symptoms of the nose, eyes and lungs. It is more likely that reactions to food fungi are caused by the food’s direct effect on blood vessels. For example, fermented foods (like wine) may naturally contain a substance known as histamine.

Histamine is also a chemical your allergy cells release during an allergic reaction. Foods that contain histamines can trigger allergy-like responses when you consume them.

How Do Doctors Diagnose Mold Allergy?

To diagnose an allergy to mold or fungi, the doctor will take a finish medical history. If they suspect a mold allergy, the doctor often will do skin tests or allergen specific IgE blood tests. Extracts of diverse types of fungi may be used to scratch or prick the skin. If there is no reaction, then you probably don’t own an allergy. The doctor uses the patient’s medical history, the skin testing results and the physical exam to diagnose a mold allergy.

How Can I Prevent an Allergic Reaction to Mold?

There is no cure for allergies.

But you can reduce your allergy symptoms by avoiding contact with the mold spores. Several measures will help:

Reduce Your Exposure to Mold Spores Outside

  1. Limit your outdoor activities when mold counts are high. This will lessen the quantity of mold spores you inhale and your symptoms.
  2. Wear a dust mask when cutting grass, digging around plants, picking up leaves and disturbing other plant materials.

What Is a Mold Allergy?

If you own an allergy that occurs over several seasons, you may be allergic to the spores of molds or other fungi. Molds live everywhere. Upsetting a mold source can send the spores into the air.

Mold and mildew are fungi. They are diverse from plants or animals in how they reproduce and grow. The “seeds,” called spores, travel through the air. Some spores spread in dry, windy weather. Others spread with the fog or dew when humidity is high.

Inhaling the spores causes allergic reactions in some people.

Allergic symptoms from fungus spores are most common from July to early drop. But fungi grow in numerous places, both indoors and exterior, so allergic reactions can happen year round.

Although there are numerous types of molds, only a few dozen cause allergic reactions. Numerous molds grow on rotting logs and fallen leaves, in compost piles and on grasses and grains. Unlike pollens, molds do not die with the first killing frost. Most outdoor molds become inactive during the winter. In the spring they grow on plants killed by the freezing.

Indoors, fungi grow in damp areas. They can often be found in the bathroom, kitchen or basement.

  • What Molds Are
  • Biocides



Five of the Most Common Indoor Molds

  • Aspergillus: Generally found in warm, extremely damp climates, and a common occupant of home dust; produces mycotoxins; can cause lung infections.
  • Cladosporium: This extremely common outdoor fungus can discover its way indoors to grow on textiles, wood, and other damp, porous materials; triggers hay fever and asthma symptoms.
  • Penicillium: Extremely common species found on wallpaper, decaying fabrics, carpet, and fiberglass duct insulation; known for causing allergies and asthma; some species produce mycotoxins, one being the common antibiotic penicillin.
  • Alternaria: Commonly found in your nose, mouth, and upper respiratory tract; can cause allergic responses.
  • Stachybotrys: Extremely toxic “black mold” that produces mycotoxins that can cause serious breathing difficulties and bleeding of the lungs, among other health problems.

    Thankfully, less common in homes than the other four, but not rare; found on wood or paper (cellulose products), but NOT on concrete, linoleum or tile.

Mold illness is the variety of health problems that can happen from any type of mold exposure. Although a mold allergy is the most common problem caused by exposure to mold, mold can cause illness without an allergic reaction. Mold can also cause infections or irritants and toxic reactions. Infections caused by mold can lead to a variety of problems from flu-like symptoms to skin infections and even pneumonia.

Mold toxicity is also an issue, and it is considered a Chronic Inflammatory Response!

An acute and chronic, systemic inflammatory response acquired following exposure to the interior environment of a water-damaged building with resident toxigenic organisms, including, but not limited to fungi, bacteria, actinomycetes, and Mycobacterium serve as inflammogens!

Lesson 2 — What Mold Needs to Grow

To grow indoors, mold needs moisture and food. Moisture is the most significant factor influencing mold growth indoors. Controlling indoor moisture helps limit mold growth.

Moisture control is the key to mold control.

Condensation

Mold does not need a lot of water to grow. A little condensation, in a bathroom or around a window sill, for example, can be enough.

Common sites for indoor mold growth include:

  1. Basement walls
  2. Areas around windows
  3. Near leaky water fountains
  4. Bathroom tile and grout
  5. Around sinks

Common sources of water or moisture include:

  1. Condensation due to high humidity or freezing spots in a building
  2. Humidification systems
  3. Slow leaks in plumbing fixtures
  4. Sprinkler systems
  5. Roof leaks
  6. Floods

Flooding

Besides moisture, mold needs nutrients, or food, to grow.

Mold can grow on virtually any organic substance. Most buildings are full of organic materials that mold can use as food, including:

  1. Cloth
  2. Wood
  3. Plant material
  4. Paper
  5. Soil

In most cases, temperature is not an issue; some molds grow in warm areas, while others prefer cool locations such as bread stored in a refrigerator. Often, more than one type of mold can be found growing in the same area, although conditions such as moisture, light and temperature may favor one species of mold over another.

Buildings that own been heavily damaged by flood waters should be assessed for structural integrity and remediated by experienced professionals.

What are the signs of mold allergies

Please note that the guidelines covered in this course were developed for damage caused by clean water (not flood water, sewage, or other contaminated water).

Lesson 1 — What Molds Are

Partially decomposed beech leaf.

Molds are organisms that may be found indoors and outdoors. They are part of the natural environment and frolic an significant role in the environment by breaking below and digesting organic material, such as dead leaves. Also called fungi or mildew, molds are neither plants nor animals; they are part of the kingdom Fungi.

Magnified mold and mold spores

Molds can multiply by producing microscopic spores (2 — microns [µm] in diameter), similar to the seeds produced by plants.

Numerous spores are so little they easily float through the air and can be carried for grand distances by even the gentlest breezes. The number of mold spores suspended in indoor and outdoor air fluctuates from season to season, day to day and even hour to hour.

Mold spores are ubiquitous; they are found both indoors and outdoors. Mold spores cannot be eliminated from indoor environments. Some mold spores will be found floating through the air and in settled dust; however, they will not grow if moisture is not present.

Mold is not generally a problem indoors — unless mold spores land on a wet or damp spot and start growing.

As molds grow they digest whatever they are growing on. Unchecked mold growth can:

  1. Rot wood
  2. Damage drywall
  3. Cause structural damage to buildings
  4. Damage buildings and furnishings
  5. Cause cosmetic damage, such as stains, to furnishings

The potential human health effects of mold are also a concern. It is significant, therefore, to prevent mold from growing indoors.
