Does Mold Affect Your Asthma or Any Allergy?

If you feel that your asthma or allergy is deteriorating and you cannot identify the reason, the cause might be mold development. As this can be serious, it is crucial to treat it immediately. 

Mold Development and Health 

Mold exposure develops specific symptoms in people similar to other triggers. People suffering from asthma or allergies may develop congestion, runny nose, frequent sneezing, skin rashes, watery eyes, chest stiffness, chronic cough, shortness of breath, and gasping. 

People usually consider these as common asthma symptoms or allergies and are likely to ignore stimulation caused due to mold or pollen. It is normal to experience health issues seasonally, but off-season might be a reason for the inspection. 

Some types of mold can be risky for health as they discharge harmful toxins. On the contrary, the reaction to mold exposure that happens due to allergies and asthma is usually different. Reactions to mold occur because a person’s immune system detects mold spores as a foreign particle and attacks. Hence, your body produces increased mucus and discharge water from the eyes to kick out allergens. 

People who have allergic asthma may experience even worse symptoms. Their immune system discharges cells and chemicals that cause irritation and tightening of the bronchial tubing. It causes difficulty in normal breathing. 

Mold Types Explained 

Some of the mold types known to trigger asthma and allergy conditions include Alternaria, Aspergillus, and Trichophyton. 


While airborne mold particles can aggravate asthma and allergy symptoms, the mold type Alternaria creates severe triggers. You must know that Alternaria can be found everywhere (outdoors) in air or soil.  


Aspergillus is a widespread indoor and outdoor mold type. Hence, people come in contact very often. When asthma or allergy patients get exposed to Aspergillus, it can cause asthma attacks and deteriorating health conditions. 

Constant exposure to Aspergillus may lead to developing a chronic disease known as bronchopulmonary aspergillosis (ABPA). This health disorder causes severe allergic reactions in the lungs, leading to bronchiectasis. Bronchiectasis is a severe health condition characterized by air passages infection and soreness. ABPA outbreaks lead to breathing issues that are similar to asthma. 


Trichophyton causes fungal skin infections in humans. Asthma patients and people allergic to Trichophyton can develop severe symptoms when exposed. 

Signs of Mold Growth 

Mold grows in moist, dark, and warm conditions. When conditions are favorable, it can develop on all surfaces, including walls, floorings, cloths, plants, eatables, and other materials. Some of the everyday things contributing to mold growth include water spills, outflows, and condensation. 

When the environment is humid, roof or pipe leaks, flood invades, lack of ventilation, surfaces become damp, and window seals break mold growth cannot be avoided.

The lab tests include skin allergy tests, radioallergosorbent tests, or blood tests. The treatment consists of managing the symptoms and avoiding further exposure.
