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.

Catching a cold during winter is fairly common because viruses spread more easily in packed indoor settings, and cold weather can weaken the immune defence inside the nose, making it harder to fight infections. Having a stuffy nose or a mild cough is one thing, but many people often confuse their illness with a cold when it may actually be flu. Flu symptoms are usually more intense and can include fever, headaches and body aches, along with a dry cough and sore throat. A cold, on the other hand, tends to peak within two to three days, with recovery usually taking about a week.

Cold vs Flu: Why Knowing the Difference Matters

With a strong flu strain causing disruption across the UK, knowing how to tell the difference between a cold and flu has become especially important. Berkshire NHS, which has around 17,100 followers on TikTok, has outlined three key differences between the two illnesses.

In a caption, the community NHS trust said: “Cold and flu symptoms can look similar, but flu is usually more severe. The flu vaccine helps protect against flu. Visit the NHS website to learn more.”

NHS Shares 3 Symptoms to Tell Cold and Flu Apart

The video features an NHS staff member pointing out three signs as she walks toward the correct option. The first is that flu comes on suddenly, often within a few hours, while a cold mainly affects the nose and throat. The final sign is that flu can leave you feeling drained and too unwell to go about your normal routine.

Can Flu Get Better on Its Own?

Flu often clears up on its own, but it can make some people very unwell. That is why it is important to get vaccinated if you are advised to do so and to follow safe distancing to reduce the spread of infection.

Cold Symptoms in Children: What Parents Should Know

Cold symptoms can last longer in young children. They may become more irritable, struggle with eating and sleeping, breathe through their mouth, and sometimes vomit after coughing. As per NHS, try to get enough rest over the Christmas holidays if possible, drink plenty of fluids, and eat nourishing food to help lower the risk of illness.

Mothers who use minoxidil, a widely used hair loss treatment, may increase the risk of infantile hypertrichosis in babies, a condition marked by excessive hair growth across the body, including areas where hair does not usually grow, according to a large international analysis.

Minoxidil Use by Mothers Linked To Potential Health Risks In Infants

Researchers from the Ministry of Health and Family Welfare and the All India Institute of Medical Sciences (AIIMS), New Delhi, reviewed 2,664 worldwide reports of suspected infantile hypertrichosis linked to minoxidil. Of these, 45 cases involved children aged between birth and 23 months.

The analysis showed that 22.2 per cent of these infant cases were associated with maternal exposure to minoxidil. Accidental exposure accounted for 44.4 per cent, while the cause remained unclear in 33.3 per cent of cases. The findings were published in the Archives of Dermatological Research.

What Is Minoxidil?

Minoxidil is a drug most commonly used to treat pattern hair loss, known as androgenetic alopecia, in both men and women. In higher oral doses, it is also prescribed for severe high blood pressure. The medicine works as a vasodilator, meaning it helps widen blood vessels to improve blood flow.

What Is Infantile Hypertrichosis?

Infantile hypertrichosis (also called childhood hypertrichosis or werewolf syndrome) is a rare condition marked by excessive hair growth on the face, back, arms, and other areas, appearing from infancy, often with a genetic cause but sometimes triggered by medications (like minoxidil) or underlying conditions, leading to significant cosmetic and psychological distress despite being a generally harmless cosmetic issue

Minoxidil: Eye-Related Side Effects Also Reported

The study also highlighted concerns beyond infant cases. Researchers identified 1,669 global reports of eye-related adverse effects linked to minoxidil use in the general population, including 25 cases reported from India.

Commonly reported eye symptoms included swelling of the eyelids, blurred vision, and central serous chorioretinopathy, a condition in which fluid accumulates beneath the retina and can affect eyesight.

Background on Minoxidil

Minoxidil was originally developed to treat high blood pressure. It was later reformulated as a topical treatment for hair loss in both men and women after its hair growth–stimulating side effects were observed. The drug is typically applied directly to the scalp or affected skin areas, the researchers noted.

Minoxidil: Concerns Over Regulation and Use

Despite its proven effectiveness, the researchers raised concerns about the drug’s widespread over-the-counter availability and limited regulatory oversight. These factors, they said, increase the risk of misuse and unintended exposure.

Although minoxidil is generally advised against for use during pregnancy and breastfeeding, the analysis still identified cases of infantile hypertrichosis linked to maternal exposure during these periods.

The researchers noted that minoxidil has also been associated with eye-related side effects in the broader population, prompting renewed questions about its overall safety profile.

“This study aims to examine global reports of infantile hypertrichosis associated with maternal minoxidil exposure and to assess serious and non-serious eye disorder cases reported in India, with the aim of improving awareness about the risks of early-life or accidental exposure,” the authors wrote.

The study was based on data collected up to March 2025 from VigiBase, the World Health Organization’s global database of suspected adverse drug reactions.

This year had been a year of flu, fiver, bacterial illness and more. One of the over the counter medicine that many people often buy, or is prescribed, especially for bacterial infections is Amoxicillin.

What Is Amoxicillin?

It is a widely prescribed antibiotic that is used to treat bacterial infections in children and adults. It is part of the penicillin class of medications and it inhibits the growth of bacteria and allows the immune system to efficiently eliminate the infection. It is commonly used to treat bacterial infections affecting the respiratory tract, urinary tract, and skin.

However, about 5 to 10 per cent of children prescribed this may develop skin rashes as a common side effect. A rash can develop in two forms: allergic and non-allergic. A rash from the drug Amoxicillin could last up to a week.

What Kind Of Rashes Are Caused By Amoxicillin?

A Maculopapular rash is a flat rash that occurs like red patches, raised bumps and spreads over the body.

Hives are itchy, raised red or skin-colored welts that can change shape and location.

Erythema Multiforme are more severe, featuring target-like lesions or bull's-eye shapes with central red spot, pale ring, and red outer ring.

Anaphylactic Reaction is a rare but severe allergic reaction that includes symptoms like difficulty in breathing, swelling of the face, lips, or tongue, hives and rapid drop in blood pressure.

Non-Allergic Amoxicillin Rash are flat, red spots that may be slightly raised, but not harmful. These usually appear o the 5th to 7th day after the start of amoxicillin and can appear on the chest, abdomen, back, face, arms, and legs. It may get worse before it starts to get better.

What Signs Should You Look Out For?

Warning signs include rashes within two hours of the first amoxicillin dose, difficulty breathing or swallowing, or very itchy hives.

The allergic reaction is caused by one's immune system reacting to that medication as if it were a foreign invader in the body.

More girls than boys develop these rashes, and in children this is even more common. In fact, the rash by amoxicillin was first noted in 1960s, in children who were being treated with ampicillin, recorded the Journal of Pediatrics.

What Can You Do If You Get Amoxicillin Rashes?

Among treatment, the first step should be to see your physician and immediately stop taking the medication. Drinking water and enough fluids can also help. Your doctor too would prescribe you medications and lotions to soothe your itching.

Hives can also be treated with the over the counter drug Benadryl. However, you must go see your doctor or GP, and not self medicate.

A doctor may treat the rash in various ways, including stopping the medication as the first line of defense. Then the doctor may give oral antihistamines (e.g., cetirizine) for the itch. Some doctors may use topical steroids to help with the itch and redness.

Before visiting your doctor, take photos of your rash, send it to your GP, as if it is contagious. Even after you start the treatment, stay in touch with your healthcare provider for any development.
