What causes Candida, and what are the symptoms? 

Candida is a type of fungus commonly found on the skin and in the gut and is usually harmless until it overgrows. Excessive growth of Candida in the gut can cause flare-ups of existing gastrointestinal diseases such as ulcerative colitis and Crohn's disease.

Candida overgrowth is also called:

  • Candidiasis
  • A Candida infection
  • Yeast infection
  • A fungal infection
  • Thrush

Common causes of Candida

An ordinarily harmless infection causes candida with a yeast fungus of the Candida genus, usually Candida albicans (Monilia albicans). The yeast fungus should be present in healthy people. However, the fungus can multiply in the mouth or intestines if a patient is receiving chemotherapy or broad-spectrum antibiotics that suppress the bacterial flora normally present in the body. Other health conditions such as pregnancy or diabetes mellitus may also make the patient susceptible to a candida infection.

  • Inflammation of the gut 

Diseases such as ulcerative colitis and Crohn's disease predispose a person to Candida overgrowth, as there are already lesions in the gut that fungi can easily infect.

  • Diabetes

Diabetes increases blood sugar levels, which creates a favorable environment for fungi to colonize.

  • Taking proton pump inhibitors (PPI)

PPIs are used to treat acid reflux. The decrease in acid production increases the risk of bacterial and fungal build-up.

  • Antibiotics 

Antibiotics, especially broad-spectrum antibiotics, kill many good bacteria in the gut that are used to fight candida.

  • Steroid use 

Long-term use of steroids can compromise the immune system and increase the risk of bacterial infection in the body.

  • Immunosuppressive drugs

Cancer drugs impair immune cells and increase the risk of bacterial build-up.

Common symptoms of Candida

When Candida starts to overgrow, it can lead to various health problems. Symptoms of Candida overgrowth vary depending on where it occurs, what type of infection is present, and how severe it is.

Fungal infections usually manifest as an itchy red rash that often appears in skin folds. On the toenails, there may be discoloration and cracking of the nails.

Oral thrush causes redness, pain, cracking and white lesions in the mouth and tongue. In the throat, there may also be difficulty eating or swallowing.

Thrush in the genital area causes redness, itching, irritation, and white discharge. Yeast infections of the urinary tract can cause burning pain when peeing and an increased urge to urinate.

Symptoms of candida overgrowth in the intestines include:

  • Stomach pain
  • Diarrhea
  • Constipation
  • Bloating
  • Bloating
  • Nausea

Headaches, fatigue, and memory issues are sometimes reported as symptoms of candida overgrowth, but they are not recognized signs.

Symptoms of Candida overgrowth of the gut overlap with various gut problems. Therefore, it is essential to see your doctor to rule out other conditions and determine if you may have a Candida overgrowth.
