Candida Overgrowth

What Is Candida Overgrowth?

Candida overgrowth, also known as candidiasis or a yeast infection, is a condition caused by an overgrowth of Candida, a type of fungus that normally lives in the human body, including the digestive system and vaginal area.

Under normal circumstances, Candida is kept under control by the body's natural defense mechanisms and the presence of other beneficial bacteria in the body. However, certain factors such as a weakened immune system, prolonged use of antibiotics, high sugar or carbohydrate diets, hormonal imbalances, and stress can disrupt this balance, leading to an overgrowth of Candida.

The overgrowth of Candida can cause a variety of symptoms, including digestive issues such as bloating, gas, and diarrhea, as well as vaginal yeast infections, skin rashes, fatigue, brain fog, and mood changes. In severe cases, it can lead to systemic candidiasis, a serious condition that can affect various organs and systems in the body.

Treatment for candida overgrowth typically involves a combination of dietary changes, probiotics, antifungal medications or herbs, and addressing any underlying health issues that may be contributing to the overgrowth.

Common Symptoms Of Candida Overgrowth:

Candida overgrowth can cause a variety of symptoms and health issues. Some of the common symptoms of candida overgrowth include:

  • Digestive issues such as bloating, gas, diarrhea, and constipation
  • Vaginal yeast infections
  • Skin rashes, including eczema, psoriasis, and acne
  • Fatigue, brain fog, and difficulty concentrating
  • Mood swings, anxiety, and depression
  • Recurrent infections, including urinary tract infections and sinus infections
  • Joint pain and stiffness
  • Allergies and sensitivities to certain foods and environmental triggers

In addition to these symptoms, there is some evidence to suggest a connection between candida overgrowth and neuropsychiatric conditions such as depression, anxiety, and ADHD. Some researchers believe that candida overgrowth may lead to changes in the gut microbiome and the production of neurotoxins that can affect brain function and mood.

Furthermore, candida overgrowth can contribute to leaky gut syndrome, which allows toxins and undigested food particles to enter the bloodstream and trigger inflammation, which has also been linked to various neuropsychiatric conditions.

It's important to note that the link between candida overgrowth and neuropsychiatric conditions is still a subject of ongoing research, and more studies are needed to fully understand this connection. If you are experiencing symptoms of candida overgrowth or a neuropsychiatric condition, it's important to talk to your healthcare provider to determine

   Testing & Diagnostics

The Organic Acid Test (OAT) is a diagnostic tool used to detect a wide range of metabolic and nutritional imbalances in the body, including Candida overgrowth. The OAT measures various organic acids in the urine, which can provide valuable information about the body's metabolic processes.

When it comes to Candida overgrowth, the OAT can help identify specific organic acids that are produced as a result of the overgrowth. For example, elevated levels of D-arabinitol, tartaric acid, and citramalic acid can indicate a Candida overgrowth.

The OAT can also detect imbalances in other areas that may contribute to Candida overgrowth, such as nutrient deficiencies and oxidative stress. These imbalances can weaken the immune system and create an environment that is favorable for Candida to grow and thrive. 



In addition to detecting Candida overgrowth, the OAT can also identify other underlying health issues that may be contributing to the symptoms. This can help guide treatment and provide a more holistic approach to addressing the root cause of the problem.

It's important to note that the OAT is just one tool in the diagnosis of Candida overgrowth and should be used in conjunction with a thorough medical history, physical exam, and other diagnostic tests as needed. Treatment for Candida overgrowth should be individualized based on the underlying cause and severity of the condition.



Exploring Neuropsychiatric Connections


Clostridium (Bacteria)

Has been associated with

Neuropsychiatric Conditions: 

  • Depression
  • ASD (Autism)¬†
  • Bipolar¬†

Gastointestinal Conditions: 

  • Irritable Bowel Syndrome (IBS)¬†
  • Ulcerative Colitis¬†
  • Candida Overgrowth

Clostridium and Candida are two types of microorganisms that are linked to neuropsychiatric conditions. Clostridium is a type of bacteria that can produce toxins, which can damage nerve cells in the brain and lead to various neuropsychiatric symptoms. For example, some strains of Clostridium have been linked to symptoms of autism spectrum disorder (ASD), such as impaired social communication and repetitive behaviours.

Candida (Yeast)

Has been associated with

Neuropsychiatric Conditions: 

  • Anxiety
  • Depression
  • Chronic Fatigue Syndrome (CFS)¬†

Other Conditions: 

  • Migraines
  • Fibromyalgia¬†
  • Cognitive Decline

Clostridium and Candida are two types of microorganisms that are linked to neuropsychiatric conditions. Candida, on the other hand, is a type of yeast that can overgrow in the gut, leading to a condition known as candidiasis. Candida overgrowth can cause inflammation in the gut, which can in turn lead to inflammation in the brain, resulting in a variety of neuropsychiatric symptoms, including anxiety, depression, and cognitive dysfunction.
