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.

While thalassemia is known widely as a blood disorder, its impact can extend far beyond anemia and transfusions, said experts on World Thalassemia Day today.

World Thalassemia Day is observed every year on May 8 to raise awareness about the inherited blood disorder caused by faulty genes.

The disorder, which often requires blood transfusions every fortnight, affects approximately 1.3 million people living with severe forms of thalassemia worldwide. About 1.5 percent of the global population is carriers, and the disease claims nearly 11,000 lives annually.

Speaking to HealthandMe, health experts raised concerns about the growing mental health and neurological challenges faced by patients, especially children and young adults living with the condition.

Dr. Praveen Gupta, Chairman – Marengo Asia International Institute of Neuro & Spine (MAIINS), Gurugram, shared that repeated blood transfusions are important and save the lives of thalassemia patients, but long-term transfusion therapy can potentially lead to neurological complications if not properly monitored.

“Chronic transfusions can cause iron overload, which is the accumulation of iron in critical organs such as the brain, and may impact cognitive and psychological function, as well as mood,” Dr. Gupta explained.

He added that "changes in oxygen supply and related complications may make patients more vulnerable to headaches, lethargy, or even undetected brain injury".

However, experts stress that most neurological complications can be prevented through multidisciplinary care, iron chelation therapy, and regular monitoring.

Can Thalassemia Affect Brain Development in Children?

The expert stated that thalassemia may also indirectly affect brain development in children, particularly when severe anemia continues for long periods and limits oxygen supply to the growing brain.

Dr. Gupta noted that poor oxygenation, nutritional deficiencies, iron overload from repeated transfusions, and metabolic complications may affect:

• Cognitive function
• Learning ability
• Attention span
• Overall neurodevelopment
• Early warning signs may include:
• Delayed speech
• Difficulty concentrating
• Poor school performance
• Frequent headaches
• Irritability
• Developmental delays

Early Signs Parents Should Not Ignore

Dr. Vipin Khandelwal, Sr. Consultant Paediatric Haemato Oncology & BMT at Apollo Hospitals Navi Mumbai, told HealthandMe that thalassemia affects the blood’s ability to carry oxygen, and prolonged disruption can impact growth, immunity, bone health, and learning abilities.

“The early signs of thalassemia are often subtle, which is why many families miss them until anemia becomes severe,” he said.

Parents should watch for persistent symptoms such as:

• Unusual tiredness
• Pale appearance
• Poor appetite
• Difficulty gaining weight
• Delayed growth
• Delayed walking or speech
• Reduced stamina
• Bone pain
• Recurrent weakness

He stressed that while thalassemia is inherited, many serious complications can be prevented with early diagnosis, regular check-ups, timely transfusions, and proper iron monitoring.

Further, the experts also highlighted risk of anxiety, stress, low self-esteem, and depression among people with thalassemia who face lifelong blood transfusions, frequent hospital visits, leading to physical fatigue, and fear of complications. Over time, these challenges may increase, many often go unnoticed or untreated.

Dr. Roshan Dikshit, Senior Consultant, Haematology & Bone Marrow Transplant at Aakash Healthcare, told HealthandMe that thalassemia is not only a physical health condition, but also an emotional and psychological challenge. He stressed the need to provide mental support to thalassemic patients.

“Frequent hospital visits, lifelong blood transfusions, fear of complications, and social limitations can increase the risk of anxiety, stress, and depression, especially among teenagers and young adults,” said Dr. Roshan Dikshit, Senior Consultant, Haematology & Bone Marrow Transplant at Aakash Healthcare.

According to Dr. Dikshit, many patients struggle with:

• Low self-esteem
• Isolation
• Emotional fatigue.

Importantly, these emotional challenges often go unnoticed.

“Mental health support should be considered an essential part of thalassemia care. Counseling, family support, social acceptance, and open communication can significantly improve a patient’s emotional well-being and quality of life,” he said.

He also emphasized that early psychological intervention can help patients cope better with the disease and reduce the long-term mental health burden associated with chronic illness.

Many women experience bloating, acidity, stomach discomfort, or constipation from time to time. These symptoms are usually linked to diet, stress, or minor digestive issues. However, these are often overlooked.

On World Ovarian Cancer Day, doctors are urging women to pay closer attention to such recurring symptoms and seek timely medical advice.

World Ovarian Cancer Day is observed every year on May 8 to raise awareness about ovarian cancer and promote early detection. This year’s theme is “No Woman Left Behind.”

According to global estimates, nearly 250,000 women are diagnosed with ovarian cancer each year, and about 140,000 die from the disease.

What Is Ovarian Cancer?

Ovarian cancer is one of the deadliest gynecological cancers and is often referred to as the “silent killer” because its early symptoms are vague and easily mistaken for common digestive or urinary issues.

It develops when abnormal cells in the ovaries grow uncontrollably and may spread to other parts of the body. Survival rates are significantly higher when detected early—around 93 per cent of women diagnosed at stage one survive at least five years, compared to just 13 per cent at stage four, according to the American Cancer Society.

Unfortunately, many cases are diagnosed at advanced stages, when treatment options are limited, and outcomes are poorer.

Early Symptoms Often Overlooked

“Ovarian cancer is commonly called a ‘silent disease’ because its early signs are vague and often resemble routine gastric issues,” Dr. Tejinder Kataria, Chairperson – Radiation Oncology, Medanta Hospital, Gurugram, told HealthandMe.

Common symptoms include:

• Persistent bloating
• Feeling full quickly or reduced appetite
• Pelvic or abdominal discomfort
• Unexplained constipation or diarrhea
• Ongoing indigestion
• Excessive gas
• Abdominal heaviness

One should not ignore these symptoms if they persist for more than two to three weeks.

“Many women delay seeking medical attention because these symptoms feel too common to be serious. Early evaluation through clinical examination, imaging, and blood tests can help detect the disease earlier,” Dr Kaur noted.

“The growing tumor can press on nearby organs such as the intestines or bladder, leading to digestive changes and abdominal discomfort,” she explained.

Risk Factors to Be Aware Of

The experts also highlighted several risk factors that are often overlooked, including:

• Family history of ovarian or breast cancer
• BRCA1 or BRCA2 gene mutations
• Increasing age, especially after menopause
• Reproductive history, such as late pregnancy or never having children

Why Early Detection Matters

Being aware of subtle and persistent symptoms can significantly improve outcomes. Ovarian cancer survival rates are much higher when diagnosed early, making timely medical consultation crucial.

Thalassemia, particularly thalassemia major and thalassemia intermediate, can affect fertility and pregnancy due to iron overload caused by repeated blood transfusions. In these patients, excess iron gets deposited in various endocrine and vital organs, leading to hormonal disturbances and fertility-related complications.

Patients with thalassemia major usually require regular blood transfusions for survival, sometimes every one to three months. Thalassemia intermediate patients may require fewer transfusions, but they too remain at risk of iron overload. Over time, excess iron can accumulate in organs such as the pituitary gland, thyroid, ovaries, kidneys, liver, and suprarenal glands. This iron deposition can impair hormonal function and contribute to infertility. Experts note that many patients with thalassemia major may face fertility issues because of this reason.

Pregnancy In Women Living With Thalassemia

Dr. Sunil Bichile, Hematologist, Saifee Hospital, Mumbai, said, "Although thalassemia management has improved significantly over the years, pregnancy in such patients is still considered high-risk. " Even when iron levels are properly managed, risks to both the mother and fetus may still exist. However, these complications are mainly seen in thalassemia major and thalassemia intermediate patients. Individuals with thalassemia minor generally do not face these fertility or pregnancy-related issues and can have normal pregnancies."

"Doctors also emphasise the importance of carrier screening and prenatal diagnosis. If both partners are thalassemia carriers, prenatal testing around 12 weeks of pregnancy can help determine whether the fetus has thalassemia major. Early diagnosis allows families and doctors to make informed medical decisions and helps reduce severe thalassemia cases," Dr Bichile added.

Ensuring Healthy Pregnancies In Women Living With Thalassemia

Women with thalassemia are now increasingly able to experience healthy pregnancies due to advances in medical care. However, one of the most important concerns during pregnancy in thalassemia patients is iron overload—a condition caused by repeated blood transfusions over many years. Excess iron gets deposited in vital organs such as the heart, liver, and endocrine glands, potentially leading to serious complications if not managed properly before conception and during pregnancy.

How Does Iron Overload Affect Pregnancy?

"Iron overload can significantly increase pregnancy-related risks. When excess iron affects the heart, it may lead to cardiac complications such as arrhythmias or heart failure, which can worsen during pregnancy because of the increased workload on the cardiovascular system. Iron deposition in endocrine glands may also cause hormonal imbalances, affecting fertility and increasing the risk of gestational diabetes, thyroid disorders, or difficulties in maintaining a healthy pregnancy," Dr Liza Bulsara, Pediatric Hematologist and Oncologist, Ruby Hall Clinic, Pune, explained.

Women with poorly controlled iron overload may face a higher chance of miscarriage, fetal growth restriction, preterm delivery, or complications during childbirth. In some cases, liver dysfunction caused by iron accumulation can further complicate pregnancy management. Additionally, anaemia associated with thalassemia itself may increase fatigue and reduce oxygen supply to both mother and baby if not carefully monitored.

Dr Bulsara emphasised that pre-pregnancy counselling is essential for women with thalassemia. A detailed assessment of iron levels through serum ferritin tests and MRI evaluation of the heart and liver helps doctors determine whether the body is prepared for pregnancy. Proper iron chelation therapy before conception plays a crucial role in reducing excess iron stores and improving maternal outcomes. During pregnancy, transfusion schedules, haemoglobin levels, cardiac health, and fetal growth require close multidisciplinary monitoring.
