What are the symptoms of Candida overgrowth or other fungus?

Overgrowth of Candida or other fungi can cause various symptoms depending on where in the body the fungus is present. Candida is a yeast that can naturally occur on the skin, in the mouth, in the genital area, and in the intestines, but when there is an imbalance it can overgrow and cause problems. Symptoms can be local, for example in the mouth or on the skin, but can also affect digestion or the whole body if the infection becomes more extensive. Below we go through common symptoms of Candida and fungal overgrowth in different parts of the body.

Oral candidiasis – oral thrush

Oral candidiasis, also called oral thrush, occurs when Candida overgrows in the oral cavity. It is particularly common in people with weakened immune systems, dry mouth, after antibiotic treatment, or when using inhaled corticosteroids.

Common symptoms of oral thrush are:

• White, creamy patches on the tongue, the inside of the cheeks, and sometimes on the palate, gums, or tonsils
• Redness, irritation, and burning in the mouth
• Cracks at the corners of the mouth, also called angular cheilitis
• Pain or discomfort when eating and swallowing
• Altered or reduced taste

Vaginal candidiasis – vaginal yeast infection

Vaginal candidiasis, or vaginal yeast infection, is a common form of Candida overgrowth. It can occur after a course of antibiotics, with hormonal changes, pregnancy, diabetes, or a weakened immune system.

Typical symptoms of a vaginal yeast infection are:

• Itching and irritation in the vagina and on the vulva
• Thick, white, cottage cheese-like discharge, usually without a distinct odor
• Redness and swelling of the vulva
• Burning during urination
• Pain or burning during intercourse

Cutaneous candidiasis – fungal infection of the skin

Cutaneous candidiasis means that Candida or other fungi grow on the skin. It often occurs in warm and humid skin areas, especially in skin folds where the fungus thrives more easily.

Common symptoms of skin fungus are:

• Red rashes, often with itching and a burning sensation
• Moist, irritated, or scaly skin areas
• Discomfort in skin folds, for example under the breasts, in the groin, between fingers, or between toes
• Small pustules, rashes, or blisters around the affected area

Intestinal candidiasis – Candida in the intestines

Candida in the intestines, sometimes called intestinal candidiasis, is often associated with digestive issues and a feeling of imbalance in the stomach. Symptoms can vary and overlap with other gastrointestinal problems, making it important to investigate recurring or long-lasting issues.

Possible symptoms of Candida overgrowth in the intestines are:

• Bloating and gas
• Abdominal pain or cramping
• Diarrhea or constipation
• Fatigue and low energy
• Increased cravings for sugar and carbohydrates

Invasive candidiasis – severe systemic fungal infection

Invasive candidiasis is a serious form of Candida infection where the fungus spreads in the blood or to internal organs. This is uncommon in healthy individuals, but can occur in people with severely weakened immune systems, after major surgery, in intensive care, or with certain medical treatments.

Symptoms of invasive candidiasis can be:

• Fever and chills that do not improve with antibiotic treatment
• Signs of infection in various organs, depending on where the fungus has spread
• Breathing difficulties
• Confusion or mental changes
• General malaise and profound weakness

Can you have several symptoms at the same time?

Yes, it is possible to have several symptoms of Candida or other fungal overgrowth at the same time. The problems can, for example, occur in the mouth, on the skin, in the genital area, and in the stomach. The risk of more widespread issues can increase if the immune system is weakened or if the body’s microbial balance has been disrupted, for example after antibiotic treatment, prolonged stress, or other stressors. Candida can also change form and develop so-called hyphae, which makes it easier for it to adhere to tissues and become more difficult to manage. Therefore, it is important to take recurring or long-lasting fungus-related symptoms seriously.

When should you seek medical care?

You should contact healthcare if the symptoms are severe, recur frequently, do not improve with treatment, or if you have a weakened immune system. In case of fever, chills, breathing difficulties, confusion, or suspected disseminated infection, you should seek care immediately.

Summary

Symptoms of Candida overgrowth or other fungi can look different depending on where the infection is located. Common signs are white patches in the mouth, itching and discharge with a vaginal yeast infection, red itchy skin rashes, digestive issues, fatigue, and in severe cases fever or involvement of internal organs. Since the symptoms can resemble other conditions, it is important to get the right assessment for long-lasting or recurring issues.
