Body odor is natural part of human physiognomy, while some people may experience less of it, it can be stronger in others. This odor is not uniform throughout your body, certain body part smell more, like your armpits, groin and feet. The Cleveland clinic explains that this smell is due to bacteria and smell on your skin. Your body odor can also change if you are on medication, or ate a certain food or even experience some hormonal changes.

Similarly, It's common for belly buttons to have a slight odor, but sometimes it can become noticeable and unpleasant. While a little smell is often nothing to worry about, a strong, foul odor, especially when combined with other symptoms, could be a sign of a more serious problem. It's important to understand the possible causes of a smelly belly button so you can take the right steps to address it. Knowing when to simply clean it better versus when to seek medical help is key to keeping yourself healthy.

Possible Causes of Belly Button Odor

If your belly button smells bad and you also have redness, swelling, pain, or bleeding, you should see a doctor. These symptoms could be a sign of an infection that needs medical treatment Here are some reasons why this may be happening.

Not Cleaning It Well

Just like any other part of your body, your belly button needs regular cleaning. If you skip cleaning it with soap and water, things like dirt, sweat, and natural oils can build up inside. As explained above, his buildup creates a breeding ground for bacteria, which can lead to a musty or unpleasant smell. This is especially true if you have a deep belly button, as it has folds and crevices that are harder to reach and clean properly. A deep belly button is a warm, damp place, which is exactly what bacteria love.

Stuff Getting Stuck

Even if you take regular showers, your belly button can still collect things like dead skin cells, lint from your clothes, and other small pieces of debris. WebMD explains that these things can get trapped inside, and when mixed with moisture from sweat or water, they can start to smell bad. Sometimes, these things can clump together and form a hard, smelly lump called a navel stone. This stone can be quite smelly, even though it's usually not painful.

Bacterial Infections

We all have bacteria on our skin, but sometimes they can cause infections. According to WebMD if bacteria get inside your belly button, especially through a small cut or scratch, they can multiply and cause an infection. Infections like impetigo and cellulitis can cause redness, swelling, pain, and pus, along with a bad smell. People with weak immune systems or poor blood flow are more likely to get these infections. If these infections are not treated, they can lead to serious problems, so it's important to see a doctor.

Yeast Infections

Yeast, which is a type of fungus, can also grow in your belly button, especially if it's warm and moist. According to the Cleveland Clinic a common type of yeast is Candida. Yeast infections can cause a sour, bread-like smell, along with redness and itching. Sweating a lot, wearing tight clothes, or taking antibiotics can increase your risk. People with diabetes or weak immune systems are also more likely to get yeast infections. These infections usually go away with antifungal creams, but it's important to keep the area dry to prevent them from coming back.

Cysts

Cysts are small, fluid-filled bumps that can form under the skin. They can happen when dead skin cells and oils get trapped in your belly button. Most of the time, these cysts are harmless and don't cause any problems. But sometimes, they can become infected, which can cause them to swell, become red, and release a gray or white discharge with a cheesy smell. If a cyst gets infected, it might need to be drained by a doctor.

Piercings

If you have a belly button piercing, it's very important to keep it clean. If you don't clean it properly, bacteria can build up around the piercing and cause an infection. Signs of an infection include pain, redness, swelling, and smelly pus. If the infection is not treated, it can spread to your bloodstream and cause serious health problems. Cleaning your piercing regularly with warm, soapy water can help prevent infections.

Parkinson's disease is a progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells, primarily affecting people over 60. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety and swallowing problems.

The first symptom may be a barely noticeable tremor in just one hand or sometimes a foot or the jaw. Over time, swinging your arms may become difficult and your speech may become soft or slurred. The disorder also causes stiffness, slowing of movement and trouble with balance that raises the risk of falls.

However, before clear symptoms begin to appear, Neurologist Rachel Dolhun says certain signs may help identify the onset of the disease decades before it is diagnosed.

“It’s important to stress that not everyone who has these symptoms goes on to develop Parkinson’s,” said neurologist Rachel Dolhun. “But we know that in some people, these can be some of the earliest signs," she told The Washington Post.

Here is what you should look out for:

1. Loss Of Smell

Loss of smell, or hyposmia, is a common and early non-motor symptom of Parkinson's disease, affecting up to 90 percent of patients. This symptom can significantly impact quality of life by reducing the enjoyment of food and diminishing appetite.

While strongly linked to Parkinson's, smell loss can also stem from other causes, including sinus problems, COVID-19, or aging.

2. Acting Out Dreams

Acting out dreams, known as REM Sleep Behavior Disorder (RBD), involves physically enacting vivid, often unpleasant dreams through shouting, punching, or kicking during sleep.

This typically happens because the brainstem fails to temporarily paralyze muscles during REM sleep. It is a strong early warning sign of Parkinson's disease, often appearing years or decades before motor symptoms. About 50 percent of people with Parkinson's experience RBD.

3. Constipation

Constipation is a very common and significant non-motor symptom of Parkinson's disease that is caused by nerve changes slowing gut muscles and potentially exacerbated by low activity and dehydration.

Constipation can also be caused by Parkinson's medications such as anticholinergics, amantadine and other common drugs such as opioids, iron/calcium antacids.

4. Dizziness As You Stand

The autonomic nervous system fails to properly constrict blood vessels or increase heart rate upon standing, often due to a lack of norepinephrine. This causes the autonomic nervous system to fail in regulating blood pressure. Over time, this leads to Neurogenic Orthostatic Hypotension.

Beyond dizziness, symptoms include blurred vision, weakness, fatigue, cognitive "fog," and "coat hanger pain" (pain in the neck/shoulders). Often times, patients experience dizziness in the morning or immediately after meals.

Diagnosing Parkinson’s disease is mostly a clinical process, meaning it relies heavily on a healthcare provider examining your symptoms, asking questions and reviewing your medical history. Various imaging and diagnostic tests used to detect disease includes CT scan, PET scan, MRI scan and genetic testing.

Beyond icy roads and fogged-up car windscreens, the coldest season can also bring on a painful condition that leaves the skin covered in red, itchy patches. Doctors have issued a warning about this lesser-known illness, which tends to worsen in low temperatures.

The condition, known as cold urticaria, affects around one in 2,000 people. It causes swelling and itching of the skin when it comes into contact with cold air, cold water, or even air conditioning. Red welts or hives can appear within minutes, and the discomfort may last for as long as two hours.

What Is Cold Urticaria?

Cold urticaria is an uncommon condition in which the body reacts abnormally to cold temperatures. It typically causes rashes or hives after exposure to cold air, water, food, or drinks. In some cases, symptoms can be more serious. According to the Cleveland Clinic, the condition may sometimes be linked to an underlying blood cancer or an infectious illness.

Griet Voet, head of a dermatology clinic in Ghent, Belgium, as per Express UK, said the condition is often confused with common winter skin problems such as eczema. “This is not just dry skin caused by cold weather, it is a genuine allergic reaction to cold,” she explained. In more severe cases, large areas of the body may be affected, particularly after swimming in cold water or spending extended periods outdoors. This can lead to intense itching, facial flushing, and even headaches, stomach pain, or fainting. Sudden temperature shifts, such as moving from a warm indoor space into cold outdoor air, can also trigger symptoms. Drinking ice-cold beverages may cause swelling of the lips, mouth, or throat.

Cold Urticaria: What Are The Symptoms Of This Disease?

Symptoms of cold urticaria differ from person to person and can range from mild to severe. They may be limited to a small patch of skin or spread across the entire body.

The most common sign is a skin rash that appears after contact with something cold. The rash usually develops once the exposure ends, as the skin begins to warm up.

The rash may include:

• Hives, bumps, or raised welts
• Itching
• Redness
• Swelling

• Fatigue
• Fever
• Headache
• Joint pain

• Fainting
• Heart palpitations
• A severe allergic reaction known as anaphylaxis
• Shortness of breath or wheezing

How Is Cold Urticaria Diagnosed?

A medical professional can often diagnose cold urticaria using a simple test. An ice cube is placed on the skin, usually on the arm, for a few minutes and then removed. If a hive or rash appears several minutes later, the result is considered positive.

In cases of familial cold urticaria, diagnosis may involve exposure to cold air for a longer duration.

Doctors may also suggest blood tests to check for any underlying illness or infection that could be contributing to the condition.

Health authorities have urged the public to stay alert to Nipah virus symptoms after doctors warned that up to 75 per cent of infected patients may not survive. The UK Health Security Agency (UKHSA) has classified Nipah as a “high priority pathogen” because of its severe fatality rate and the absence of any proven treatment.

In India, the federal health ministry has confirmed two cases in the eastern state of West Bengal. This has triggered large-scale containment measures, with local officials placing nearly 200 people who had contact with the infected individuals under quarantine.

In response, several Asian nations have stepped up airport checks and health surveillance for travellers arriving from India. Professor Paul Hunter, an infectious disease specialist at the University of East Anglia, said identifying Nipah cases at borders is challenging, as symptoms can take a long time to appear.

What Is Nipah Virus?

According to UKHSA, Nipah virus is a zoonotic infection, meaning it can pass from animals to humans. It can also spread through contaminated food or via direct human-to-human contact. The virus was first discovered in 1999 during an outbreak affecting pig farmers in Malaysia and Singapore.

Fruit bats, especially those belonging to the Pteropus species, are the virus’s natural carriers. Research shows that Nipah can also infect other animals, such as pigs, dogs, cats, goats, horses and sheep.

Nipah Virus Symptoms

• Sudden onset of fever or general flu-like illness
• Development of pneumonia and other breathing-related problems
• Swelling or inflammation of the brain (encephalitis) or meningitis

Symptoms usually appear between four and 21 days after exposure, although longer incubation periods have occasionally been reported. More severe complications, including encephalitis or meningitis, can develop between three and 21 days after the initial illness begins.

UKHSA has cautioned that between 40 and 75 per cent of people infected with Nipah virus may die. Those who survive can experience long-term neurological effects, such as ongoing seizures or changes in behaviour and personality. In rare instances, the virus has been known to reactivate months or even years after the first infection.

Nipah Virus: Can You Prevent It From Spreading?

For people travelling to regions where Nipah is known to occur, prevention largely involves reducing exposure risks:

• avoid contact with bats, their habitats, and sick animals
• do not drink raw or partially fermented date palm sap; if consuming date palm juice, make sure it has been boiled
• wash all fruits well with clean water and peel them before eating; avoid fruits found on the ground or those that appear partly eaten by animals
• use protective clothing and gloves when handling sick animals or during slaughter and culling
• maintain good hand hygiene, especially after caring for or visiting ill individuals
• avoid close, unprotected contact with anyone infected with Nipah virus, including exposure to their blood or bodily fluids

Nipah Virus Symptoms Can Be Transmitted Easily?

Many Nipah infections have been linked to eating fruit or fruit-based products contaminated by the saliva, urine or droppings of infected fruit bats. Human-to-human transmission can also occur through close contact with an infected person or their bodily fluids, according to Mirror.

Such transmission has been documented in India and Bangladesh, with cases often involving family members or caregivers tending to infected patients. At present, there is no specific, proven treatment for Nipah virus infection, and no licensed vaccine is available to prevent it.

So far, no Nipah virus cases have been reported in the United States or the United Kingdom.
