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

Déjà Vu is a feeling of sensation when one person feels that they have felt or witnessed the same situation before, just like a single incident is happening once again. The word itself is from French and means "already seen." Though there is a common misconception among people that Déjà Vu is a very rare occurrence, in reality, this apparently mysterious experience happens to almost 97 percent of people's lives. Thus, it is a very common thing that will be felt by most people at least once in their lifetime.
As mentioned before, the word itself shows the very aspect of Déjà Vu that it's already seen. Suppose you are having a deep conversation with your friend, family, or a stranger, but you feel like this is not the first time you are having this conversation; you already know the topics and outcomes, as if you are living the same moment that you have lived before.
On the other hand, you might be visiting a new place, maybe a new city that you have never visited, but the places, houses, and overall atmosphere feel very recognizable. You suddenly feel that you have visited that place before and have felt good or bad in the past, as if you are living a past in your present.
All in all, this kind of strange phenomenon that happens to people regularly, this kind of uncomfortable feeling which is felt by 97 percent of people in the world, is called Déjà Vu.
The root cause of this strange phenomenon is believed to be a result that one place or any conversation or any situation is resembling the same kind of pattern or feelings that you have experienced and felt before, and in most cases, you yourself have forgotten that, but your brain has not, and it recreates this sense of familiarity, and you feel you are living in a paradox.
In other words, déjà vu occurs when two parts of your brain fail to communicate properly: the temporal lobe, which handles memories, and the hippocampus, which processes new experiences.
There are certain things that can cause Déjà Vu more than others, such as fatigue or sleep deprivation, stress, and anxiety, which can trigger the feeling of Déjà Vu, as this pressure on your mental and physical health might pressure your brain and distort the recognition process. Other than that, migraine, dementia, and seizure can also cause Déjà Vu in a person.
Occasional déjà vu is generally harmless and not a cause for concern. However, if it happens frequently, lasts more than a few seconds, or is accompanied by other symptoms, it may be a good idea to seek medical advice.

As the FIFA World Cup 2026 is underway, players are navigating demanding training schedules, frequent travel, challenging weather conditions, and the pressure to perform at their peak. Amid these challenges, many elite footballers quietly face an often-overlooked problem off the field: sleep disturbances.
In an exclusive interview with HealthandMe, Dr. P.S.M. Chandran, former Director of Sports Medicine at the Sports Authority of India (SAI), said that the stress, anxiety, and disrupted routines associated with elite sport can make it difficult for players to get adequate rest. In some cases, these challenges may drive athletes toward sleeping medications, potentially affecting both their health and on-field performance.
Dr. Chandran, currently President of the Indian Federation of Sports Medicine (IFSM), said that while players may turn to sleeping pills as a quick solution, regular use can become a habit that leads to dependence if left unchecked.
Recently, striker Omar Bogle, who plays for Crewe Alexandra in League Two, shared his story with The New York Times' The Athletic about the moment last year when he became addicted to sleeping pills and painkillers.
What began as a way to help him sleep after suffering a back fracture during pre-season in the summer of 2024 became an addiction.
From January 2025, his usage accelerated to an alarming level. He said that many of the pills he was taking were benzodiazepines, such as diazepam and lorazepam. He was also using the stronger zopiclone pills, which the NHS says can be prescribed for the short-term treatment of severe insomnia.
"No one knew the extent of what I was doing," he said. "I never told anyone I was popping 18 or 19 of the things in the night."
Bogle's is not alone.
In January 2026, former England midfielder Jonjo Shelvey revealed on a podcast how he had become addicted to sleeping pills because of the loneliness he experienced while playing in Turkey. Shelvey said his dependence affected his relationship with his children.
Former Manchester United midfielder Darron Gibson also developed a sleeping pill addiction and, at his worst point, was taking 12 to 14 tablets a night, according to The New York Times.
In 2023, former Tottenham Hotspur and England midfielder Dele Alli told the BBC that he had become addicted to sleeping pills to block out past traumas.
According to Dr. Chandran, the issue is not unique to football but affects athletes across multiple sports, driven by stress, performance pressures, injuries, and demanding schedules.
"Football is not an exception," Dr. Chandran said. "Because of its popularity, we hear more about football players, but athletes in other sports face similar problems."
Elite footballers operate in a high-pressure environment where careers can be influenced by contracts, team selection, injuries, and performance expectations. Frequent travel, changing time zones, training camps, and irregular eating patterns can further disrupt normal sleep cycles.
According to Dr. Chandran, these factors create significant psychological stress, making it difficult for athletes to unwind and get adequate rest.
"Athletes are always stressed because of their contracts with clubs, their interaction with coaches, and concerns about injuries that can affect their income," he explained. "All these tensions bring stress, and stress leads to sleep disturbance."

Sleep plays a crucial role in athletic recovery. Without adequate rest, muscle repair, mental focus, and physical performance can suffer.
"If athletes do not get good sleep, the next day's training will suffer," Dr. Chandran said. "To get better sleep, they try sleeping pills. That becomes an escape route for them."
However, he warned that regular use of sleeping medications can quickly develop into dependence.
"Once they start taking sleeping pills, it becomes a habit. It is difficult to get out of it," he told HealthandMe.
The expert noted that while occasional use under medical supervision may be appropriate in certain situations, unsupervised and prolonged use can worsen sleep problems and lead to dependence.

Stress hormones such as cortisol, adrenaline, and noradrenaline are naturally involved in exercise and performance. However, elevated stress levels can interfere with healthy sleep patterns.
These hormones increase alertness, heart rate, and metabolic activity—responses that may be useful during competition but can make it difficult to fall asleep afterward.
Dr. Chandran emphasized that athletes should seek professional guidance when dealing with sleep issues rather than relying on self-medication.
Modern sports science places a strong emphasis on recovery, recognizing it as an essential component of performance. Elite football clubs now employ teams of physiotherapists, psychologists, nutritionists, doctors, and recovery specialists to help athletes maintain optimal health.
"Training leads to tiredness, and tiredness has to be overcome by recovery methods," Dr. Chandran said. "The better you recover, the better you can perform the next day."

The loss of a tooth is often viewed as a purely dental concern, but its impact extends far beyond appearance. Missing teeth can affect chewing efficiency, speech, facial structure, and even emotional well-being. While traditional tooth replacement options have served patients for decades, modern implant dentistry has transformed the way tooth loss is managed. Today, dental implants are not merely about filling a gap; they are about restoring function, confidence, and overall quality of life.
Dr. Achuth M. Baliga, Director, Happiest Pearls, said, "One of the greatest advantages of dental implants is their ability to closely replicate the function of natural teeth. Unlike removable dentures that may shift or cause discomfort, implants are anchored securely within the jawbone, providing exceptional stability. This allows individuals to chew a wider variety of foods with confidence and comfort."
The expert went on to say that proper chewing is essential for nutrition and digestive health. Patients who struggle with missing teeth often avoid certain foods such as fruits, vegetables, nuts, and proteins, potentially compromising their dietary intake. By restoring full chewing efficiency, dental implants help individuals maintain a balanced and nutritious diet, contributing to better overall health. Dr Baliga also answered more FAQs on the subject.
Tooth loss triggers a process known as bone resorption, where the jawbone gradually deteriorates due to the absence of stimulation from the tooth root. Over time, this can lead to changes in facial appearance, including a sunken or prematurely aged look.
Dental implants address this challenge by functioning like artificial tooth roots. They stimulate the surrounding bone during everyday activities such as chewing, helping to preserve bone volume and density. This not only supports long-term oral health but also helps maintain natural facial contours. In many cases, implants play a significant role in preserving a youthful appearance and preventing the structural changes associated with prolonged tooth loss.
The psychological effects of missing teeth are often underestimated. Individuals may become self-conscious about smiling, speaking, or interacting socially. Concerns about appearance can affect personal relationships, professional interactions, and overall self-confidence.
Dental implants provide a fixed and natural-looking solution that blends seamlessly with surrounding teeth. The ability to smile without hesitation and speak without worrying about movement or instability can have a profound impact on emotional well-being. Many patients report feeling more confident in social settings and more comfortable expressing themselves after completing implant treatment.
Missing teeth, particularly in the front of the mouth, can interfere with pronunciation and speech clarity. Similarly, loose or ill-fitting dentures may cause slurring or difficulty articulating certain sounds.
Because implants are securely integrated into the jawbone, they provide the stability needed for clear and natural speech. Everyday activities such as eating in public, participating in meetings, or engaging in conversations become more comfortable and predictable. These seemingly small improvements can significantly enhance daily living and social participation.
Advancements Making Treatment More Predictable
Modern implant dentistry has benefited greatly from technological innovations. Digital imaging, three-dimensional treatment planning, guided implant placement, and advanced restorative materials have improved precision and predictability. These advancements allow clinicians to tailor treatment plans to each patient's unique anatomy and functional requirements.
In addition, improved understanding of bone biology and soft tissue management has contributed to higher success rates and more aesthetically pleasing outcomes. As a result, implant therapy has become a reliable long-term solution for a wide range of patients experiencing tooth loss.
Implant dentistry today is centred on patient outcomes rather than simply replacing missing teeth. The goal is to restore oral function, maintain facial structure, support emotional well-being, and improve overall quality of life. Successful treatment considers not only the clinical aspects of tooth replacement but also the patient's lifestyle, expectations, and long-term health needs.
