Does Mold Cause Diarrhea?

When mycotoxins produced by mold are inhaled or ingested in significant amounts, they can disrupt the body's natural detoxification processes, leading to symptoms like diarrhea, nausea, and even more severe conditions like GERD.

Furthermore, these toxins can strain the liver, which is crucial in filtering harmful substances from our body. Understanding the relationship between black mold and digestive issues is essential for ensuring both personal and public health.

Molds, or more precisely, dangerous strains like Aspergillus, can severely impact one's health. That's not the worst one; the dreaded “black mold” has been used as a biological weapon.

Mold can cause diarrhea because mold in the body produces toxins that can irritate your intestines. Mold is a bit more complicated than one would assume in most cases. The symptoms of mold exposure vary widely depending on the person affected.

Most exposure can affect the body in numerous ways. While it most often affects the body reacts respiratory system, mold is capable of having other adverse effects on one's health.

For example, if you have immune deficiencies, mold is more capable of making you sick than people that have a normal immune system.

Mold exposure, whether it's black mold or another variety, can lead to a wide array of health issues, ranging from mild to severe. A simple stuffy nose might be the first indication of exposure, but more serious symptoms may emerge as exposure persists. These include difficulty breathing and chest tightness, which can escalate to potentially fatal pulmonary hemorrhaging or bleeding in the lungs.

It's particularly important to note that individuals with compromised immune systems or those with chronic lung disease are at increased risk of developing fungal infections in the lungs. These conditions can be compounded by hypersensitivity pneumonitis, an immune-mediated condition causing inflammation of the lungs.

Workplaces with mold presence pose a serious health concern. Studies show that mold exposure at work can exacerbate pre-existing asthma. Hypersensitivity pneumonitis (HP), a form of lung inflammation, can occur when people develop immune system sensitization to inhaled organic dust, which often contains mold spores.

HP's symptoms may mirror pneumonia, but it doesn't respond to antibiotics as pneumonia does. The variability of HP's symptoms can sometimes complicate diagnosis, making the condition even more concerning.

The impact of mold exposure extends beyond respiratory complications. High concentrations of airborne mold can interfere with the body's ability to eliminate waste and toxins effectively. This can result in a host of digestive system issues, including diarrhea, vomiting, and gastroesophageal reflux disease (GERD).

Severe cases might even lead to internal bleeding. Thus, it's critical to maintain a mold-free environment, not just for respiratory health but for overall well-being.

The skin, the body's largest organ, can also provide visible signs of mold exposure. Skin problems may manifest as rashes, itching, or more complex conditions.

Moreover, exposure to mold can exacerbate sinus congestion, allergic rhinitis, and allergic bronchopulmonary aspergillosis, especially in individuals with weakened immune systems. Hence, paying attention to any signs or symptoms that your body might be reacting to mold in your environment is essential.

Additional Symptoms

The toxins mold produces that irritate your intestines can also lead to other symptoms. It is common to experience vomiting, nausea, headaches, fever, or abdominal pain.

This is on top of the myriad of other symptoms of mold exposure that can be caused by common household molds that typically affect the skin and create respiratory system problems.

Other Health Effects of Mold Exposure

Mold exposure most often leads to respiratory illnesses that strongly affect the respiratory system but can cause other health problems. The symptoms most often associated with toxic mold exposure are as follows:

  • Coughing
  • Sneezing
  • Sore throat
  • Chest pain
  • Chest tightness
  • Respiratory problems
  • Digestive problems such as stomach pain
  • Difficulty breathing
  • Skin irritation
  • Irritation in eyes

These symptoms can worsen exponentially if you already have a weakened immune system.

How Do You Know If Mold Is Making You Sick?

If you cannot determine a logical cause for any of the symptoms you are experiencing, including diarrhea, then you should speak with your doctor and voice your concern that you may have been exposed to mold.

Your doctor will be able to administer a mold test to determine whether or not you are experiencing symptoms of mold exposure. Your doctor will then likely prescribe you antifungal medications to combat your symptoms and their cause.

You should also have a mold test done in your home; if it comes back positive, mold removal becomes the next important thing to perform.

When you want to have mold removed from your property, it's important to hire a professional mold remediation service to do the work. Water damage companies will often provide this service, but not always.

10 Tips for Reducing Mold-Related Diarrhea

Avoid Mold-Susceptible Foods

Temporarily avoid foods prone to mold growth or relying on fermentation. This includes aged cheeses, cured meats, leftovers, and fermented products like sauerkraut or kombucha.


Properly Store and Handle Food

Follow essential food safety practices. Ensure perishable foods are stored at proper temperatures, refrigerate leftovers promptly, and practice good hygiene while handling and preparing meals.


Follow Doctor's Orders

Take any prescribed medications as directed by your doctor. Adhere to the recommended dosage and duration of the treatment plan. If approved by your doctor, over-the-counter medications may help relieve nausea.


Rest and Hydrate

Resting is vital to allow your body to recover. Also, drink plenty of water to replenish lost fluids and electrolytes. Consider consuming clear fluids like broths, herbal teas, or electrolyte-rich beverages.


Consume Light, Nourishing Foods

Opt for easily digestible, low-fiber foods during recovery. This may include plain rice, boiled potatoes, lean proteins, and cooked vegetables. Gradually reintroduce other foods as your symptoms improve.


Maintain Good Hygiene Practices

Practice thorough handwashing before handling food or eating to minimize the risk of ingesting additional mold or harmful bacteria.


Create a Mold-Free Living Environment

Address the root cause of mold in your living spaces. Identify and remediate any sources of moisture, improve ventilation, and consider using dehumidifiers to reduce humidity levels.


Enhance Indoor Air Quality

Utilize air purifiers with HEPA filters to reduce airborne mold spores and improve the overall air quality in your home.


Seek Professional Mold Remediation

If your mold-related symptoms persist or your home has extensive growth, consult professionals specializing in mold remediation to ensure proper removal and prevention.


Consult a Healthcare Professional

If your symptoms persist or worsen, consult a healthcare professional for further evaluation and guidance tailored to your specific situation.


In assessing the impact of black mold, suspect mold in your environment, and act immediately. These mold spores could infiltrate your system, inciting multiple health issues.

One can't overlook the connection to diarrhea, perhaps induced by fungal infections. Furthermore, mold spores may also lead to respiratory illnesses, intensifying the urgency of mold eradication and prevention.
