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.

Many people may dismiss swelling in an arm or leg, particularly if it's not painful. But if the swelling continues or keeps coming back, it could be a sign of lymphedema, a condition that affects the body's lymphatic system.

The lymphatic system is responsible for draining excess fluid from body tissues. If this system is damaged or is not functioning correctly, fluid will accumulate, and lead to swelling. There are different causes of lymphedema such as some infections, injuries, congenital disorders and cancer therapies. Women who have had breast or gynaecological cancers may be at special risk if they had their lymph nodes removed or if radiation had been used.

What are the WARNING SIGNS?

Sometimes, lymphedema develops gradually. Signs and symptoms include swelling of one arm or leg, heaviness or tightness in the arm or leg, trouble putting on rings or a watch, and decreased movement in the arm or leg.

At times, the skin can also be tight and turn into a hard consistency over time. In certain patients, a second infection of the skin may occur.

These symptoms should not just be attributed to "normal swelling. An early evaluation may help determine the root cause and make the condition less complicated to deal with.

What Is The Treatment For Lymphedema?

Treatment will depend on the severity of the disease and its etiology. Treatment usually involves compression garments, special physiotherapy, gentle lymphatic massage, exercises and skin care. The techniques may be used to help decrease swelling and movement.

Surgery may be necessary in some cases of more severe or chronic lymphedema. New pathways can be created to allow the excess fluid to pass, such as in a lymphovenous bypass. For some patients, a transfer of lymph nodes or liposuction may be an option.

Additionally, for patients who have an increased risk of developing lymphedema, doctors may also recommend preventive measures for individuals who must have some type of cancer surgery. This implies that measures should be taken to ensure protection of the lymphatic drainage before any appreciable swelling occurs.

When To Go To The Doctor?

If swelling isn't severe, don't wait to get help. If there is any continued or unexplained swelling, there will be a specialist available to give information about the cause of the swelling and what treatment is appropriate.

Patients are provided with a holistic treatment pathway for lymphedema with multiple specialists treating their patients who came together for the diagnosis, rehabilitation and surgical treatment of lymphedema.

Treatment of lymphedema is not all about reducing swelling. The overall aim is to maintain a person's function, ease and independence in their daily activities.

If diagnosed early, and appropriately treated and followed-up, lymphedema can be managed successfully and patients can lead their life with a growing sense of confidence and comfort.

AIIMS New Delhi has successfully performed its second dual kidney transplant using organs from a marginal donor. The procedure highlighted a strategy that could help make greater use of kidneys that may otherwise be rejected for transplantation.

The procedure was carried out on July 28 by a multidisciplinary team from the Departments of Surgical Disciplines, Nephrology, Anaesthesia, Transplant Immunology and the Organ Retrieval Banking Organisation (ORBO).

The donor was a 70-year-old woman from Command Hospital, Chandimandir, Chandigarh. Because of her advanced age and the marginal characteristics of the donated kidneys, doctors transplanted both kidneys into a single 56-year-old woman.

The organs were transported from Chandigarh to New Delhi by an Army helicopter. According to AIIMS, despite a cold ischaemia time of 12 hours, both kidneys were functioning immediately after transplantation.

The recipient showed no complications after the transplantation and was discharged after 10 days with normal kidney function.

What Is A Dual Kidney Transplant?

In a conventional kidney transplant, one donated kidney is transplanted into a recipient. Meanwhile, in a dual kidney transplant both kidneys are placed into one patient from the same deceased donor.

The approach is considered when the donor is older or the kidneys have characteristics that suggest that a single kidney may not provide sufficient function.

In simple terms, two kidneys that have lower individual functional capacity may be able to provide adequate overall kidney function when transplanted together.

Research has previously found that dual kidney transplantation can be a viable option for kidneys from older or marginal donors. Transplant teams carefully assess the donor organs and recipient before deciding whether using both kidneys together could provide adequate renal function.

A 2025 analysis comparing single and dual transplantation from marginal donors also highlighted the potential of using kidneys from a deceased donor.

Need Of The Hour

The milestone comes as India faces shortage of transplantable organs. India recorded 20,138 organ transplants in 2025, crossing the 20,000 mark for the first time, but the number of patients needing transplants remains far higher than the available organs.

Recent reports has also highlight the country's mounting transplant needs that still remain unmet despite its position as one of the world's largest transplant centres by volume.

This makes the ability to safely use organs from older or marginal donors particularly important.

“Dual kidney transplantation from carefully selected marginal donors represents an important strategy for increasing the utilization of deceased-donor organs,” AIIMS said in the press release.

AIIMS said the successful transplant demonstrates its efforts to “maximize the utilization of marginal donor organs” and help patients with end-stage kidney disease receive organs at the earliest.

Encouraging Development

The immediate functioning of both kidneys despite around 12 hours of cold storage is certainly encouraging. However, the patient’s discharge with normal kidney function represents an early outcome.

Longer follow-up will be needed to determine how well the transplanted kidneys perform over the months and years ahead.

The AIIMS team was led by Prof. Asuri Krishna, with support from the nephrology, anaesthesia, transplant immunology, ORBO and organ retrieval teams.

It is a common belief that metabolic dysfunction-associated steatotic liver disease (MASLD)—formerly known as non-alcoholic fatty liver disease (NAFLD)—is primarily associated with diet, sedentary lifestyles, and obesity. However, there are other factors as well affecting this aspect. Post-menopausal women experience a significantly higher incidence and faster progression of fatty liver disease, even when maintaining a stable body weight.

Why Menopause Increases Fatty Liver Risk

In pre-menopausal women, oestrogen plays a central role in metabolism, by promoting healthy fat accumulation in subcutaneous tissue (below the skin) rather than around internal organs, it also increases insulin sensitivity and suppresses liver inflammation.

After menopause when oestrogen levels drop, this protective function is lost, there is redistribution of fat leading to more fat accumulation around internal organs including liver thus leading to increase chances of NAFLD and also increasing insulin resistance, needless to say that with age our metabolic rate also goes down which also plays a role in this.

Early Detection Is Key

The important part lies not only in understanding above but to go further in early detection and prevention of menopause associated NAFLD. As we know that fatty liver is a silent disease and often does not causes any signs and symptoms till very advanced stage.

First and foremost is to change lifestyle with advancing age, changing both the dietary habits and physical activity. Regular screening and monitoring is warranted with blood tests, routine metabolic panels, keeping a tab on weight, sugar and cholesterol levels and a basic ultrasound of abdomen.

For someone already diagnosed with 2nd or 3rd stage fatty liver, a simple non-invasive. Fibroscan can help monitor and assess the response to treatment.

Understanding The Impact Of Menopause On Liver Health

Coming to treatment part of NAFLD in post-menopausal women, it being primary a lifestyle disease so the core of management also lies around managing lifestyle. Medicines are available for treating and controlling NAFLD in conjunction with lifestyle management.

Hormone replacement therapy (HRT), when initiated early in post-menopausal women for symptomatic relief may offer secondary benefits by maintaining metabolic health. However HRT should always be initiated after proper evaluation and expert guidance.

NAFLD is a silent epidemic and primarily a life style disease, knowing about it and knowing triggering and precipitating factors helps understanding and prevention better.

Menopause being a natural biological phenomenon in every female’s life, it becomes essential for us to know how it affects our liver health and overall health as well.
