Can Thrush Make You Feel Sick and Tired


Thrush, also known as a yeast infection or candidiasis, is a common fungal infection caused by an overgrowth of the Candida species, usually Candida albicans. It typically affects the mouth, throat, genital area, or skin. While thrush is generally considered a localized condition, many individuals wonder whether it can make you feel sick and tired. In this article, we will explore the relationship between thrush and overall feelings of illness and fatigue.

Understanding Thrush

Thrush occurs when Candida, a naturally occurring fungus in the body, grows out of control. Normally, the body’s immune system and healthy bacteria keep Candida in check. However, several factors can disrupt this balance and lead to thrush, including:

Antibiotic use: Antibiotics can disrupt the balance of microorganisms in the body, making it easier for Candida to overgrow.

Weakened immune system: A weakened immune system due to conditions like HIV/AIDS, cancer, or autoimmune diseases can increase the risk of thrush.

Diabetes: Poorly controlled diabetes can create an environment conducive to fungal overgrowth.

Pregnancy: Hormonal changes during pregnancy can make women more susceptible to thrush.

Poor oral hygiene: In the case of oral thrush, inadequate oral hygiene can lead to an overgrowth of Candida in the mouth and throat.

Symptoms of Thrush

The symptoms of thrush can vary depending on the affected area. Here are the common symptoms associated with oral thrush, which affects the mouth and throat:

White patches on the tongue, inner cheeks, and throat

Soreness, redness, or bleeding in the affected areas

Difficulty swallowing

Unpleasant taste in the mouth

Cracking or redness at the corners of the mouth

For genital thrush, symptoms include:

Itching and irritation in the genital area

White, thick, and odorless vaginal discharge in women

Redness and swelling of the genital area

Skin thrush symptoms manifest as red, itchy, and sometimes painful rashes with white patches.

Can Thrush Make You Feel Sick?

Thrush is generally considered a localized infection, meaning it primarily affects the area where it occurs. However, the symptoms and discomfort associated with thrush, particularly oral thrush, can make you feel unwell. The sensation of having a sore mouth, difficulty swallowing, or a persistent unpleasant taste can contribute to a general feeling of malaise.

In some cases, thrush can lead to mild fatigue because the body’s immune system is working to combat the fungal infection. This immune response can make you feel somewhat tired or run down, but it’s typically not severe.

While thrush itself doesn’t usually cause severe illness or systemic symptoms, it’s essential to consider other factors that might contribute to feeling sick or tired, especially if thrush is recurrent or persistent.

When to Seek Medical Attention

Thrush is usually treatable with antifungal medications, which may be available in the form of oral medications, topical creams, or oral rinses. If you experience any symptoms of thrush, it’s essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Treating thrush can help alleviate the discomfort associated with it and, as a result, may improve your overall well-being.

If you’re feeling exceptionally unwell or tired, it’s crucial to consider whether there might be underlying health issues contributing to these symptoms. While thrush itself may not be the primary cause of severe sickness or fatigue, it could be a sign of an underlying health condition or a weakened immune system. In such cases, seeking medical advice is crucial to address any potential health concerns.

Preventing Thrush

Preventing thrush involves maintaining a healthy balance of microorganisms in your body. Here are some steps you can take to reduce the risk of thrush:

Practice good oral hygiene: Regularly brush your teeth, floss, and use an antiseptic mouthwash if needed.

Manage underlying conditions: If you have diabetes or other health conditions that can increase the risk of thrush, work with your healthcare provider to manage them effectively.

Avoid unnecessary antibiotic use: Use antibiotics only when prescribed by a healthcare professional and finish the full course of medication.

Maintain a balanced diet: A diet rich in fruits, vegetables, and probiotic-rich foods can support a healthy microbial balance in the body.

Wear breathable, cotton underwear: In the case of genital thrush, opt for breathable fabrics and maintain good personal hygiene.


While thrush is primarily a localized fungal infection, the discomfort it causes can make you feel unwell and slightly fatigued. However, the tiredness associated with thrush is generally mild and linked to the body’s immune response to the infection.

If you’re experiencing persistent or severe feelings of sickness or fatigue, it’s crucial to consult a healthcare professional. These symptoms may be indicative of underlying health issues or conditions that require attention. By addressing both the thrush infection and any contributing factors, you can work towards restoring your overall health and well-being.
