Are you experiencing fatigue, weight gain and difficulty focusing?

These symptoms might be the result of a silent unexpected stressor on our bodies. In fact, many people who suffer from these symptoms have been living or working in a building that has been damaged by water. When roofs and walls leak and gutters and downpipes get blocked it leads to water damage in buildings. If the source of the leak is not promptly addressed, mould can begin to grow within 24-48 hours. This can result in exposure to mycotoxins, which can have effects on our health. Interestingly, statistics indicate that Sick Building Syndrome and mycotoxin exposure tend to affect women and children more adversely. Given the rainfall and humid weather conditions we've been experiencing, it's vital for us to assess our homes and workplaces to ensure that we're not unknowingly subjecting ourselves to these hidden stressors.

Mould related illnesses can manifest in various ways and impact individuals differently based on numerous factors such as genetic predisposition, overall health status, as well as the duration and intensity of exposure. Notable conditions often associated with mould exposure include Chronic Inflammatory Response Syndrome (CIRS) and Hashimoto's disease.

Chronic Inflammatory Response Syndrome (CIRS)

CIRS is an illness affecting systems within the body triggered by mycotoxin exposure, like those produced by mould. This condition is characterised by a response that can affect several organs and systems throughout the body. Mould produced mycotoxins have the potential to enter the body either through inhalation or skin contact. In individuals who are more susceptible, these toxins can trigger a response that is not properly regulated, resulting in chronic inflammation and the onset of Chronic Inflammatory Response Syndrome (CIRS). People with CIRS may experience a range of symptoms, including fatigue, difficulty concentrating, respiratory problems, joint discomfort, headaches and gastrointestinal issues. 

Hashimoto’s Disease

Hashimoto's disease is an autoimmune disorder that affects the thyroid gland. While there can be various root causes for this condition, exposure to mould has been identified as a significant trigger. Mould toxins can disrupt the endocrine system and affect how the body and thyroid gland function. The thyroid gland is responsible for so many different processes in the body, notably hormone production and metabolic rate. Thus mould exposure can disrupt thyroid function and cause fatigue, weight gain, immune suppression, hair loss and gastrointestinal issues. The autoimmune aspect of this Hashimoto’s involves the immune system mistakenly attacking the thyroid gland as a response to a stressor which could potentially be mould.

Respiratory Issues

Inhaling mould spores can lead to problems in people who already have conditions such as asthma or allergies. These respiratory issues may include coughing,  wheezing sounds while exhaling, shortness of breath, sinus congestion causing nose sensations and throat irritation. Prolonged exposure to mould can potentially lead to the development of these conditions, especially in children. Exposure can also result in reactions, such as sneezing, itchy or watery eyes, skin rashes and the worsening of asthma symptoms. 

Brain fog and mood changes

Neurological symptoms have been associated with mould exposure due to the impact of mycotoxins on the system. Some individuals may experience difficulties, memory problems, trouble concentrating, mood swings, irritability and headaches as a result.

Chronic Fatigue

Chronic Fatigue Syndrome (CFS) also known as encephalomyelitis (ME) is an debilitating condition characterised by persistent and unexplained fatigue. While the exact cause of CFS is not fully understood there is evidence linking mould exposure to the development or worsening of symptoms. People with CFS often experience fatigue that doesn't improve with rest or sleep. They may also experience sleep disturbances, muscle weakness or pain and an inability to concentrate. Recent research has indicated a connection between mould exposure and the development of CFS. Mycotoxins might contribute to dysregulation of the nervous system and chronic inflammation, which play a role in perpetuating fatigue and other associated symptoms.

It's important to note that the severity and manifestation of illnesses related to mould can vary greatly among individuals, even between family members who are exposed collectively. It is important to seek medical attention and address mould exposure in order to manage and prevent long term health concerns. If you are already experiencing illness related to mould it is crucial that you remove yourself from the environment even though this may be difficult if it is your home. It is recommended that you take steps to remediate any water damage in order to minimise the duration of exposure to toxins. Consider hiring a building biologist who can conduct an assessment and testing of your building identifying the causes, level and species of mould present. This will provide an understanding of the necessary remediation measures needed to protect your home. If you suspect symptoms related to mould exposure it is advisable to consult with a healthcare professional, for an evaluation and appropriate detoxification protocol.
