The human belly button is a haven for bacteria, fungi, and germs, which, when combined with dead skin cells and natural oils, can result in an unpleasant odour. This odour can range from a sweaty stench to a cheesy smell. The deeper the belly button, the more likely it is to trap dirt and germs, resulting in an odour similar to blue cheese. While the smell is usually harmless, it can sometimes indicate an underlying condition, such as an infected cyst or fungal infection, which may require medical attention. Maintaining good hygiene practices, including regularly cleaning the belly button area, is essential to prevent and address belly button odour.

What You'll Learn
Poor hygiene
The belly button is a dip or indentation in the middle of the belly, marking the place where the umbilical cord was attached in the womb. This indented shape can trap moisture and provide a perfect breeding ground for odor-causing sweat, dirt, fungi, and bacteria. The deeper and more indented the belly button, the more dirt and germs can build up inside it.
Fungi, such as Candida, thrive in warm and moist environments. If Candida multiplies in the belly button, it can turn into a fungal infection, resulting in an unpleasant smell. Poor hygiene increases the risk of fungal infections, as the yeast feeds on the sugars left behind by sweat and dead skin cells.
To improve belly button hygiene and reduce odor, it is important to clean the area regularly. This can be done during a shower by lathering a finger or a wet washcloth with mild, fragrance-free soap and gently massaging the belly button to loosen and remove any buildup. The area should then be rinsed with warm water and thoroughly dried.
In addition to regular cleaning, there are other hygiene tips to keep the belly button smell-free. These include avoiding the use of lotion inside the belly button, as this can create a moist environment conducive to bacterial and fungal growth. It is also recommended to avoid nickel belly button jewelry, as this may contribute to skin irritation or infection.

Candida yeast infections
A smelly belly button is often caused by dirt or bacteria that accumulates inside it. The deeper the belly button, the more dirt and germs can build up, and the more likely it is to smell. This is because sweat produced in this area can be difficult for the body to expel, and so it decomposes and creates a foul odour.
However, in some cases, a smelly belly button can be a symptom of an infection, such as a Candida yeast infection. Candida is a type of yeast that grows and thrives in warm, damp, and dark environments. It is a common cause of fungal skin infections, especially in the warm, moist crevices of the skin, such as the belly button.
Belly button yeast infections are characterised by a bright red, itchy rash in the skin folds of the navel area. The rash may also burn, and you may notice scaling, swelling, or a white discharge. While belly button yeast infections typically do not cause a strong odour, some people may experience a slight musty smell, especially if the infection is due to a skin condition called intertrigo.
People with certain medical conditions are more prone to developing Candida yeast infections. This includes individuals with weakened immune systems, diabetes, psoriasis, and pregnant or overweight people. Additionally, wearing tight clothing, not changing clothes often, humid and hot weather, poor hygiene, and skin conditions can also increase the risk of developing a Candida yeast infection.
To prevent and treat belly button yeast infections, it is essential to keep the navel area clean and dry. Antifungal creams, ointments, or powders may be recommended by a healthcare professional to treat the infection. Maintaining good hygiene habits and managing any underlying medical conditions can help reduce the risk of developing Candida yeast infections in the belly button.

Trapped dead skin and sweat
The belly button is a small indentation in the middle of the belly, marking the place where a person's umbilical cord was attached in the womb. This hollow area can easily trap dirt, sweat, dead skin, and germs, which are difficult for air to circulate out of. This build-up of sweat and dirt can lead to the proliferation of bacteria and germs, resulting in an unpleasant odour.
The deeper and more indented the belly button, the more likely it is to trap these substances and emit a strong smell. This is because the shape of the navel makes it challenging for sweat to evaporate, providing an ideal environment for bacteria to thrive. Additionally, the belly button's proximity to the groin and underarms, which are also prone to sweating, can contribute to the accumulation of odour-causing agents.
To prevent the belly button from smelling like blue cheese or other unpleasant odours, proper hygiene is essential. Regular cleaning of the belly button with soap and water can help remove dirt, sweat, and dead skin cells that may be trapped in the indentation. Ensuring that the area is thoroughly dried after showering can also inhibit the growth of bacteria and fungi.
In addition to practising good hygiene, wearing loose-fitting clothing can help prevent excessive sweating and the trapping of moisture in the belly button area. It is also important to clean one's belly button regularly with soap, as few people remember to do so, and to seek medical attention if the odour persists or is accompanied by other symptoms such as discharge, which could indicate an infection.
While having a smelly belly button can be embarrassing, it is a common occurrence that affects many people. By maintaining proper hygiene and being mindful of the unique shape and environment of the belly button, individuals can effectively manage and prevent strong odours from developing in this area.

Belly button cysts
A smelly belly button can be caused by a variety of factors, ranging from improper hygiene to infections and skin conditions like cysts. While the smell can often be resolved with good hygiene habits, it is important to recognise when a smelly belly button may be a symptom of a more serious underlying condition.
One of the primary symptoms of an infected urachal cyst is a cloudy or bloody fluid leaking from the belly button, accompanied by a foul odour. If left untreated, the infection can lead to serious health issues, with the potential to pierce the bladder or peritoneal cavity. Therefore, it is crucial to seek medical attention if any discharge or symptoms of infection are observed.
To prevent infections and maintain a healthy belly button, it is recommended to wash daily with mild antibacterial soap and water, ensuring to clean inside the belly button to remove any dirt or debris. Keeping the area clean and dry is essential, especially after bathing. Additionally, it is advisable to avoid tight clothing, as it can irritate the belly button and promote bacterial growth.
While urachal cysts are a type of belly button cyst, there are other kinds of cysts that can form in this area, such as epidermoid cysts, which can occur anywhere on the skin. These cysts are typically not harmful but can be uncomfortable and may require surgical removal if they cause persistent issues.

Bacterial infections
The deeper and more indented the belly button, the more susceptible it is to bacterial accumulation. This bacterial growth can lead to infections, which may require medical attention. In some cases, bacterial infections in the belly button can be a symptom of underlying conditions such as diabetes or obesity.
Maintaining good hygiene practices is crucial to preventing and treating bacterial infections in the belly button. Regular cleaning with antibacterial soap and water can help remove dirt, debris, and excess oil, reducing the risk of infection. It is important to be gentle when cleaning to avoid skin irritation, which can further increase the risk of infection.
Additionally, keeping the belly button area dry and avoiding tight clothing can help prevent moisture buildup and promote ventilation. In some cases, antibacterial or antifungal creams may be recommended by a doctor to treat more severe or persistent infections.
It is important to note that while most belly button odours can be resolved with improved hygiene, persistent or worsening symptoms may indicate a more serious infection. If the smell persists or is accompanied by other symptoms such as discharge, redness, inflammation, or pain, it is advisable to consult a doctor for further evaluation and treatment.
