How does candida affect our mood?

Following on from last month’s article about getting on top of a candida/yeast infection,  Candida Albicans is a yeast that occurs naturally in the human body, but it is only one of many different types of fungi that can be problematic and lead to a decline in our general health.

During the past two decades, yeast infections have increased dramatically.  This has been attributed to a variety of factors, including: the widespread use of broad-spectrum antibiotics, the expanded use of immunosuppressive drugs, the use of intravascular devices (pacemakers etc.) and the over-abundance of sugars and starches in our diet.

Normally candida resides in the intestinal tract, mouth, throat and genitals, however it can burrow holes in the intestinal tract, enter the blood stream and then make it’s way into any organ of the body. To make matters worse it is known to emit over 70 different toxins into the body. Some people may even become allergic to the yeast itself.

Much of the body’s hormone production occurs in the intestinal tract. Ninety to 95% of our serotonin, the key neurotransmitter responsible for regulating mood, is produced inside our intestines. When the candida population reaches a certain point, it begins to suppress the production of neurotransmitters such as serotonin. A lack of serotonin leads to depression, anxiety, and other mental health problems.

Acetaldehyde, one by-product of the candida yeast, also reacts with the neurotransmitter dopamine, which also leads to mental problems, including anxiety, depression, poor concentration, and feeling spaced-out.

How do you know if you have an issue with yeast overgrowth? Before getting it tested via a blood spot test or urinary organic acid test, you can complete a questionnaire  which is from Dr William Crook’s book ‘The Yeast Connection Handbook’.

Common Yeast Overgrowth Symptoms are:

You may have a yeast problem if you have one or more of these symptoms:

General Symptoms

  • Chronic fatigue
  • Depression
  • Anxiety
  • ADHD
  • Autism
  • Anger or Rage disorders
  • Loss of energy
  • General malaise
  • Decreased libido
  • Inability to concentrate
  • Irritability
  • Skin rashes
  • Fungal nail infection
  • Ear aches
  • Migraines

Gastrointestinal Symptoms

  • Bloating and gas
  • Intestinal cramps
  • Itching in anal region
  • Diarrhoea or constipation

Urinary Symptoms

  • Yeast infections (thrush)
  • Frequent bladder infections
  • Irritable bladder (also known as interstitial cystitis)

In clinic, we will always take a thorough case history which may prompt us to investigate  further with a urinary Organic Acid Test or we might start a treatment program straight away.

It’s quite amazing what a difference it makes to most people (including children – with fewer ups & down and tantrums), when their gut flora is balanced again and they finally have more energy, less pain and feel generally happier.
