Your body hosts trillions of bacteria, viruses, and fungi, collectively known as the microbiome. While some bacteria are linked to disease, many play essential roles in supporting your immune system, heart health, weight management, and overall well-being. This article delves into the significance of the gut microbiome and its impact on health.

What Is Gut Microbiome?

Interestingly, bacterial cells outnumber human cells in the body, with approximately 40 trillion bacterial cells compared to 30 trillion human cells. With up to 1,000 species of bacteria present in the gut, each plays a distinct role. While most bacteria contribute positively to health, some can be harmful. Together, these microbes weigh around 1–2 kilograms, functioning almost like an additional organ essential for overall well-being.

How Does Gut Microbiome Influence Your Health?

The relationship between humans and microbes has evolved over millions of years, with the gut microbiome playing a crucial role from birth. Initial exposure to microbes occurs during birth, and some evidence suggests that exposure begins in the womb. As the microbiome diversifies, it starts influencing key bodily functions:

Digestion of breast milk: Beneficial bacteria like Bifidobacteria help break down essential sugars in breast milk, supporting infant growth.

Fiber digestion: Some bacteria process fiber into short-chain fatty acids, which contribute to gut health and reduce risks of obesity, diabetes, and heart disease.

Immune system regulation: The gut microbiome interacts with immune cells, influencing how the body responds to infections.

Brain health: Emerging research suggests a link between the gut microbiome and brain function, potentially affecting mental health and neurological processes.

Gut Microbiome And Weight Management

An imbalance between beneficial and harmful microbes, known as gut dysbiosis, may contribute to weight gain. Studies on identical twins—one with obesity and the other without—suggest that microbiome composition plays a role in body weight independent of genetics. Additionally, animal studies indicate that gut bacteria can influence weight gain, even when calorie intake remains constant.

Probiotics, beneficial bacteria found in supplements and certain foods, can help restore gut balance and support weight loss, though their effects may be modest.

Gut Health And Disease Prevention

The gut microbiome plays a vital role in preventing and managing conditions like irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Imbalances in gut bacteria may lead to bloating, cramps, and digestive issues. On the other hand, beneficial bacteria like Bifidobacteria and Lactobacilli help strengthen the intestinal lining, reducing the risk of gut-related disorders.

Impact On Heart Health

Research suggests that the gut microbiome influences heart health by affecting cholesterol levels and blood pressure. Certain harmful bacteria produce trimethylamine N-oxide (TMAO), a compound linked to blocked arteries and heart disease. However, probiotics, particularly those containing Lactobacilli, may help reduce cholesterol levels and promote cardiovascular health.

Blood Sugar Regulation And Diabetes Risk

The gut microbiome also plays a role in regulating blood sugar levels. Research on infants genetically predisposed to type 1 diabetes indicates that gut microbiome diversity declines before disease onset. Furthermore, individual variations in gut bacteria may explain why people experience different blood sugar responses to the same foods.

Connection Between Gut And Brain

The gut is physically connected to the brain through nerves, and certain bacteria help produce neurotransmitters like serotonin, which influence mood and mental health. Studies indicate that people with mental health disorders often have different gut bacteria compared to those without such conditions. Additionally, some probiotics have shown promise in alleviating symptoms of depression and anxiety.

Tips For Healthier Gut Microbiome

Maintaining a balanced gut microbiome is crucial for overall health. Here are some strategies to support gut health:

• Eat a diverse range of foods: A varied diet rich in fiber, legumes, and fruits promotes microbial diversity.
• Consume fermented foods: Yogurt, kefir, and sauerkraut contain probiotics that enhance gut health.
• Limit artificial sweeteners: Some artificial sweeteners can encourage the growth of harmful bacteria.
• Include prebiotic foods: Bananas, oats, and asparagus contain fibers that nourish beneficial bacteria.
• Breastfeed infants when possible: Breastfeeding promotes a healthier gut microbiome in babies.
• Choose whole grains: Whole grains contain fiber and beneficial compounds that support digestive health.
• Opt for a plant-based diet: Vegetarian diets may reduce inflammation and support a healthier gut microbiome.
• Consume polyphenol-rich foods: Green tea, dark chocolate, and olive oil contain compounds that foster beneficial bacteria.
• Take probiotics if needed: Probiotic supplements can help restore gut balance after disruptions, such as antibiotic use.
• Use antibiotics cautiously: While antibiotics can be life-saving, overuse can harm beneficial gut bacteria.

For years, doctors believed that menopause was the big trigger for heart-related changes in women. Turns out, that might not be the full story.

A new study, published in the journal Hypertension, found that something called pulse pressure starts rising in women as early as their late 30s. That's way earlier than the time most women hit menopause.

What Is Pulse Pressure?

Pulse pressure is just the gap between the two numbers you see in a blood pressure reading. The top one and the bottom one. As we age, this gap tends to widen. And when it widens too much, it's usually a sign that the aorta, the body's biggest blood vessel, is getting stiffer.

A stiffer aorta means your heart has to work harder to pump blood around your body. Over time, that extra strain adds up.

What Did The Study Find

Researchers looked at data from more than 9,500 people, over 6,500 women and around 3,000 men, all part of the Framingham Heart Study. This is one of the longest-running heart health studies in the world, and the participants were tracked across three health checkups over 14 years.

What they found was interesting. Pulse pressure hits its lowest point and then starts climbing about ten years earlier in women than in men. For women, this shift happens in the late 30s. For men, it's usually the late 40s. And by the time women reach around 60, their pulse pressure is consistently higher than men's.

This pattern showed up even when a woman went through menopause. Early, late, right on time, didn't matter. The rise in pulse pressure followed the same timeline regardless.

Gary F Mitchell, one of the researchers on the Framingham Heart Study, said the team was genuinely caught off guard by this. Menopause timing, it seems, wasn't the main thing driving the change; something else was clearly at play too.

"To our huge surprise, our results suggest that factors other than the timing of the final menstrual period were likely involved in the accelerated increase in pulse pressure in women after midlife," he noted.

Why This Actually Matters

Elevated pulse pressure isn't just a random number on a report. It's linked to a higher risk of heart disease, dementia, and even kidney disease. It can also make managing high blood pressure trickier, since some medications don't work as well once arteries get stiffer.

The bigger takeaway from this study is pretty simple. Women's heart health might need attention way earlier than we've been taught to think. Instead of waiting until menopause to start paying attention to cardiovascular health, doctors might need to start the conversation years earlier, around the late 30s.

So, if you're a woman in your 30s reading this, this isn't meant to scare you. It's just a reminder that heart health isn't something to put off until your 40s or 50s. A basic check on your pulse pressure now might tell you more than you'd expect.

Urine leakage when you cough, sneeze or exercise is often dismissed as something women simply have to live with after pregnancy or childbirth. But pelvic floor problems can affect both women and men and may interfere with daily activities, confidence, relationships and sexual health.

Many people quietly live with symptoms such as urine leakage, urgency, pelvic pressure or pain, while even those who seek medical help may not know the underlying cause. Speaking to HealthandMe, doctors said these can be signs of pelvic floor dysfunction — a treatable condition that should not be ignored.

Early identification and appropriate treatment can help prevent symptoms from disrupting everyday life.

What Is Pelvic Floor Dysfunction?

Pelvic floor dysfunction occurs when the muscles in the pelvis do not relax, contract or coordinate properly. These muscles support the bladder, bowel and reproductive organs.

According to the Cleveland Clinic, the pelvic floor muscles act like a supportive hammock. When they are too tight, weak or poorly coordinated, normal bladder, bowel and sexual functions can be affected.

Pregnancy and childbirth are important risk factors, but pelvic floor problems can also affect men. Symptoms may include urinary urgency or leakage, pelvic pain or pressure and bowel problems.

Other factors such as sedentary lifestyles, stress, obesity and constipation may be contributing to pelvic floor dysfunction.

What Can Increase The Risk Of Pelvic Floor Problems?

Dr Nirmala M, Consultant, Obstetrician, Gynaecologist & Fertility Specialist, Motherhood Hospitals, Bengaluru, told HealthandMe that sedentary office work, stress, obesity and constipation can contribute to pelvic floor problems. Poor water intake and regularly holding urine can also play a role.

“It is seen that almost four of every five cases of incontinence observed in hospitals have been identified among young women aged 25 to 35 years old,” she said.

Pelvic floor dysfunction can affect men too, particularly in association with urinary, bowel or prostate-related problems.

Dr Meghana Reddy Jetty, Senior Consultant - Obstetrics, Gynecology, Laparoscopy and Aesthetic Gynecology, Aster Women and Children, Bengaluru, said men may also experience urinary leakage and bowel control problems, including in association with pelvic operations and prostatic procedures.

“Men have pelvic floor muscles too, which are responsible for bladder and bowel control and proper functioning of the pelvis,” she said.

Symptoms can vary depending on whether the pelvic floor muscles are weak, too tight or poorly coordinated.

Common signs include:

• Urine leakage while coughing, sneezing or exercising
• A sudden or uncontrollable urge to urinate
• Difficulty emptying the bladder or bowel
• Pelvic heaviness or pressure
• Pelvic discomfort
• Pain during intercourse

Dr Nirmala said urinary leakage during physical strain and a sudden, uncontrollable urge to urinate are among the early symptoms.

Dr Meghana said occasional urine leakage, difficulty emptying the bladder or bowel, pelvic heaviness, discomfort and pain during sexual intercourse can indicate that the pelvic floor is not functioning properly.

How Can Pelvic Floor Dysfunction Affect Daily Life?

The condition can affect more than bladder or bowel control. Fear of leakage, urgency or pain may cause people to avoid exercise, travel and social activities.

Dr Nirmala said some women avoid parties and long-distance travel because of difficulty finding a nearby bathroom. In serious cases, they may rely on diapers or sanitary pads, affecting confidence and increasing stress.

Pelvic floor dysfunction can also affect sexual health. Pain and difficulty relaxing the pelvic muscles may lead women to avoid sexual activity.

“It can hurt sexual health if pain and difficulty in relaxing pelvic muscles cause one to avoid sexual activity. This kind of problem that seemingly just involves the physical aspect can slowly but surely have a great effect on one's confidence, relationships and behavior in general,” said Dr Meghana.

Can Exercise Make Pelvic Floor Symptoms Worse?

Exercise can support pelvic health, but the type, intensity and technique matter.

Dr Swati Rai, Senior Consultant-Obstetrician and Gynecologist at Cloudnine Group of Hospitals, Noida, said exercises such as Kegels, diaphragmatic breathing, pelvic tilts, glute bridges and gentle core strengthening can help support the pelvic floor during and after pregnancy, depending on the individual.

“Kegels involve gently contracting the muscles used to control urine, holding briefly and then completely relaxing; they should not be routinely practized while urinating,” she told HealthandMe.

However, excessive or improperly performed high-impact exercise, intense interval training, repeated jumping and weightlifting can place additional pressure on the pelvic floor, particularly when breathing and core control are inadequate.

Dr Meghana said pelvic-floor training should focus on muscle control rather than simply increasing repetitions.

“So, training of pelvic muscles should be more about learning muscle control - knowing when to contract and when to relax - rather than just doing more and more repetitions,” she said.

Dr Swati said excessive straining, breath-holding or incorrectly performed high-impact exercises may aggravate symptoms.

Is Pelvic Floor Dysfunction Treatable?

Pelvic floor dysfunction can improve significantly with appropriate, personalized treatment. However, treatment depends on whether the muscles are weak, overly tight or poorly coordinated.

Treatment may include:

• Pelvic floor retraining
• Physical therapy
• Core strengthening
• Relaxation and breathing exercises
• Biofeedback

Noncommunicable diseases such as heart disease, cancer, diabetes and chronic respiratory diseases affect billions of people worldwide and cause around 43 million deaths every year, with most deaths occurring in low- and middle-income countries.

These conditions often require lifelong care. From diagnosis and medication to monitoring and follow-up, each stage can carry safety risks, making timely, coordinated and patient-centered care essential.

World Patient Safety Day is observed every year on September 17 to raise awareness about patient safety and accelerate action to reduce avoidable harm in healthcare. Around the world, one in 10 patients experience harm while receiving health care, and approximately half of these incidents are preventable.

In 2026, the campaign focuses on safe care for noncommunicable diseases (NCDs), with the slogan “Safe care for life!”

“World Patient Safety Day is an annual reminder that if it's not safe, it's not care. This year, we're shining a light on safe care for non-communicable diseases. People with heart disease, cancer, diabetes, and chronic respiratory disease need care throughout their lives,” Dr Tedros shared in a post on X.

He noted that every interaction with the health system comes with benefits and risks.

“A delayed diagnosis, the wrong medicine, an unsafe procedure, or poor communication can have deadly consequences. Safe care must be built into every stage of the care journey, from prevention and early diagnosis to treatment, long-term management, and self-care,” the chief added.

Why Do Chronic Conditions Raise The Risk Of Harm?

People with chronic diseases often need medicines, tests, consultations and other healthcare services over many years, increasing safety risks, particularly when care is fragmented or healthcare providers are not well coordinated.

Patient safety risks can occur at different stages of care. Common sources include:

• Missed prevention opportunities

• Delayed or incorrect diagnosis

• Medication errors

• Healthcare-associated infections

• Unsafe use of medical devices

• Poor communication and coordination

How Can Patients With Chronic Diseases Stay Safe?

Understanding your diagnosis and treatment can help you take an active role in your care.

• Know your diagnosis, treatment plan and why tests or medicines are needed.

• Use trusted health sources and ask questions when something is unclear.

• Confirm instructions and follow up on test results.

• Speak up if something feels wrong.

• Keep an updated list of your diagnoses, medicines and treatment plan, especially when seeing multiple doctors.

• Attend regular appointments and know the warning signs that need medical attention.

• Plan how you will access essential medicines, tests and follow-up care during disruptions.

Continuity of care is particularly important for people with NCDs. Poorly coordinated referrals, handovers and discharge processes can create safety gaps, especially for those managing multiple conditions or medicines.

Safer Care Also Depends On The Health System

Patient safety cannot be addressed by patients alone. Strong policies, coordinated healthcare services and well-supported health workers are essential to reducing avoidable harm.

Fragmented care can put people managing complex chronic conditions at greater risk. Better communication between multidisciplinary teams can help identify problems earlier and reduce gaps in care.

Delayed referrals can also cost valuable time. Well-coordinated referral pathways can help patients receive the right care at the right time.

What Should Healthcare Systems Do?

The WHO called on healthcare facility managers, health leaders and policymakers to strengthen patient safety as part of everyday NCD care. This includes building resilient facilities, strengthening risk management, supporting health workers and establishing reliable systems for continuous care before, during and after emergencies, according to the WHO.

Healthcare systems should also ensure uninterrupted access to essential medicines, diagnostics and medical devices while strengthening referral pathways and communication between healthcare providers.

Investing in preparedness, continuous learning and quality improvement can further help reduce avoidable harm and improve the safety and quality of chronic disease care.
