10 Warning Signs of Mold Toxicity

May 28, 2025 by Janet Blade |

Know the Symptoms Before Mold Takes a Toll on Your Health

You may not see mold. You may not even smell it. But it could still be there — growing silently behind walls, under floors, or inside HVAC systems — and affecting your health every single day.

At K9 Mold Inspections LLC, we help Arkansas homeowners find hidden mold that is often the root cause of mysterious health issues. One of the most alarming concerns? Mold toxicity.

Also called Chronic Inflammatory Response Syndrome (CIRS), mold toxicity occurs when your body reacts to toxic compounds (mycotoxins) produced by certain types of mold. Over time, exposure can lead to a wide range of symptoms — many of which are mistaken for allergies, chronic fatigue, or common health conditions.

If you are not feeling well and can’t figure out why, this post is for you.

10 Warning Signs of Mold Toxicity

Here are the top ten red flags that mold could be making you sick:

1. Chronic Fatigue

If you’re sleeping 8+ hours but still feel exhausted, it could be due to mycotoxins interfering with your body’s energy production.

2. Brain Fog or Trouble Concentrating

Memory issues, mental fatigue, or a constant “foggy” feeling are common with mold toxicity. This can feel like early dementia or ADHD-like symptoms.

3. Sinus Congestion or Postnasal Drip

Constant stuffiness, sinus pressure, or mucus that won’t go away — even when you’re not sick — is a CIRS red flag.

4. Headaches or Migraines

Frequent headaches, especially ones that start at home and disappear elsewhere, could signal indoor mold exposure.

5. Respiratory Issues

Coughing, wheezing, shortness of breath, air hunger or worsening asthma symptoms are common in mold-exposed individuals.

6. Skin Rashes or Itching

Mold can trigger inflammatory responses that cause red, itchy, or burning skin. These may mimic eczema, hives, rashes, or bug bites.

7. Mood Changes or Anxiety

Mycotoxins can affect the brain and nervous system, leading to irritability, anxiety, depressive, or even rage symptoms.

8. Light Sensitivity or Blurred Vision

Visual disturbances may be a symptom of chronic mold exposure. This can include light sensitivity, blurred vision or difficulty with contrast.

9. Digestive Issues

Nausea, bloating, food intolerances, or IBS-like symptoms can occur when mold impacts gut health.

10. Worsening Symptoms in Specific Areas of Your Home

If you feel worse in a certain room (like a bedroom, basement, or office), and better when you leave, mold may be present there.

Why Mold Toxicity Is Often Misdiagnosed

The symptoms of mold toxicity overlap with many other conditions, such as:

  • Seasonal allergies
  • Chronic fatigue syndrome
  • Lyme disease
  • Fibromyalgia
  • Anxiety or depression
  • Autoimmune conditions

Most doctors don’t ask about mold exposure, which means many people live for years with undiagnosed mold-related illness.

If multiple family members are experiencing symptoms — or if you’ve had water damage in the past — it’s time to investigate your environment.

How Canine Mold Detection Helps Identify the Source

Traditional mold inspections often miss hidden mold growing behind walls, under flooring, and within HVAC systems. That’s why we use a trained scent-detection dog who can accurately locate mold — without tearing into your home.

Our mold dog is trained to pinpoint the location of mold so you can take action confidently.

We inspect homes throughout Arkansas, including Little Rock, Benton, Conway, Bryant, Hot Springs, and Sherwood.

What to Do If You Suspect Mold Toxicity
  1. Track Your Symptoms – Keep a journal of what you’re experiencing and where your symptoms worsen.
  2. Look for Clues – Past water leaks, musty smells, or visible staining may be subtle signs of hidden mold.
  3. Schedule a K9 Mold Inspection – Our non-invasive canine inspections offer fast, reliable answers.
  4. Get Medical Support – Work with a mold-literate practitioner to detox and support your recovery.
Don’t Ignore the Signs — Mold Could Be the Missing Piece

If your body is sending you signals and no one can find the cause, mold may be the hidden culprit. At K9 Mold Inspections LLC, we’re here to help you find peace of mind — and clean air — with accurate, affordable mold detection.
