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:

Delhi's air quality remained in "very poor" category, and the AQI stood at 342 at 8am, as per the Central Pollution Control Board. The 24-hour average AQI was logged at 412 under the "severe" category on Tuesday evening when Delhi's quality peaked to record the fourth severe air day in the month of December. With the air quality levels remaining continuously in the "very poor" category, Delhi's Chief Minister Rekha Gupta held a pollution review meet.
A review meeting was held to discuss the rising air pollution levels in Delhi on Monday at the Delhi Secretariat. The meeting was attended by the officials from various departments, which also included the Public Works Department (PWD), Transport, Delhi Pollution Control Committee (DPCC), Environment, and others.
Post meeting, Delhi Environment Minister Manjinder Singh Sirsa said that the CM sought responses from multiple departments to discuss various aspects of pollution in the national capital. Sirsa also confirmed that a follow-up meeting will be scheduled on Thursday to continue the discussions on various steps that should be taken to bring down the levels of Delhi's AQI.
On Sunday, a day before the meeting was held, Delhi's CM spoke on relying on public transport as a solution to Delhi's pollution. She said that the government aims to make the metro network "so comprehensive that people do not need to rely on private vehicles even for last-mile connectivity”.
An analysis by the Global Burden of Disease (GBD) 2023 found that air pollution is city's single largest health risk. The deaths rose from 15,786 in 2018 to 17,188 in 2023.
Another study published in Scientific Reports, a five-year study titled Respiratory Deposition of Particulate Matter in Delhi: A Five-Year Assessment of Exposure Patterns and Health Risks tracked how particulate matter settles inside the respiratory system and found that men's exposure can be up to 1.4 times higher, especially while walking or commuting. The study noted that men on average spend more time outdoors while working, commuting, or walking in traffic-heavy areas. This leads to an increase in exposure.
A different study published in Frontiers in Public Health, explored the data of 2,96,078 women and girls between the age of 16 to 55 years in Taiwan and correlated it with the long-term air pollution data between 2000 and 2013. None of these women had any history of dysmenorrhea before the survey had began.

Furthermore, a study published in Nature Communication notes that after four hours of exposure to particulate matter, it was found that people's ability to perform routine tasks and interpret emotions were highly impacted.
If Delhi is able to cut its local pollution by 50 per cent, the pollution too could drop by 50 per cent. The emission should happen across the airshed. However, the focus should be for a long-term action on the source of emission and not short-term optics like cloud seeding, smog towers, water sprinkling or air purifiers.
In fact, as per a study published in Sustainability (MDPI), an open access journal, which mapped Delhi's air quality between 1990 to 2022 and found that transports emit around 10 to 30% of pollution, whereas agricultural residue burning, which is a seasonal source of pollution leads to less than 3% of pollution, whereas firecrackers, another seasonal source, leads to less than 1% of pollution.

Do you feel an awful soar in your throat? Have you noticed that anyone you speak to are also complaining of the same symptoms? All of them, and you, seem tired, have a sore throat and no energy for days and weeks to follow. This might be what people are called "mystery disease" or the "mystery throat virus". However, this is actually the adenovirus.
Most patients with bad throat, explain experts have adenovirus, which is a common virus that spreads throughout the year. However, unlike the flu and COVID, which now have their own prescribed medicines, adenovirus has none.
Read: This Mysterious New Virus Could Spread Faster Than Covid-19 And Flu
Adenovirus is a virus that has more than 60 different strains, which is why it is able to cause a variety of symptoms. Adenovirus refers to a group of common viruses that usually trigger cold- or flu-like illness. It spreads easily because it is far more resilient than many other viruses. Ordinary soap, water, and standard disinfectants do not reliably destroy it, allowing it to persist in the environment. As a result, infections often cluster in places where people spend time close together, such as daycares and military barracks. The virus spreads through the respiratory tract, can be shed in stool, and can survive for some time on contaminated surfaces, according to the CDC.
The reason for its spread right now is due to the surge of flu cases in the southern hemisphere which has influenced the outbreaks in the northern hemisphere. Another reason is the lower flu vaccinate rates, which has now made a large number of population more vulnerable to infections, overall, including adenovirus.
While a lot of the symptoms mimics of those in flu or COVID, including shortness of breath, a sore throat and or a runny nose. However, there are certain unique symptoms of adenovirus that include:
Other rare symptoms could also include impact on your bladder or nervous system. As viruses in your bladder can also cause urinary tract infections, and the same virus in your nervous system can cause condition that can affect your brain. These conditions also include encephalitis and meningitis.

What makes this virus unique is that it can spread through easily. Adenovirus is highly contagious. It can spread from one person to another through shaking hands, kissing, or even hugging. The virus could also spread through sneezing, coughing, and if by any other means respiratory droplets transfers to other person in air. It can also spread by touching contaminated surface, and you can get the virus by touching your eyes, nose, or mouths if you do not wash your hands.
The virus can also spread through stool of an infected person. For instance, you can be infected while changing your baby's diaper. It can also spread through unchlorinated water, and a person can be infected with the virus if he or she swims in a pool without adequate chlorine.
Adenoviruses are resistant to many common disinfectants. Therefore, they can remain infectious on surfaces for a long time.
If you are generally healthy, and feel a little down, but do not have shortness of breathe or a high fever, you are safe to go, with supportive care at home. However, pay close attention to those who are already on medical attention, or those who are immunocompromised, or are infants.
If you are sick, have a high fever, and experiencing shortness of breath, it is best to consult your doctor. However, do not show up to your doctor's office, call first.

Ben Sasse, former Senator, on Tuesday shared that he has been diagnosed with pancreatic cancer. His diagnosis came at Stage 4.
The former two-term senator, 53, revealed this in a social media or X, message: “This is a hard note to write, but since many of you have already sensed something, I’ll get straight to it: Last week I was diagnosed with metastasized, stage-four pancreatic cancer, and I am going to die.”

Stage 4 cancers are terminal and his terminal diagnosis was "hard for someone wired to work and build, but harder still as a husband and a dad," he said.
Stage 4 cancers are terminal because the cancer has metastasized, which means it has spread from its original site or the primary tumor to distant organs and tissues. This makes it extremely difficult to cure with localized treatments like surgery or radiation.
However, the American Oncology Institute does note that stage 4 cancer always does not have to be terminal, especially with breakthrough treatment options like targeted therapy, immunotherapy, or precision medicine. There are now also advanced surgical techniques that use minimal invasion procedures.

According to the American Cancer Society, pancreatic cancer makes up about 3 percent of all cancers in the United States but accounts for roughly 8 percent of cancer-related deaths. Most patients are diagnosed at Stage 4, and the disease is widely regarded as largely incurable. Prostate cancer, by contrast, is the second most common cancer among men, and the majority of those diagnosed do not die from it. The five-year relative survival rate for non-metastasized prostate cancer is 97.9 percent, dropping to about 38 percent once it spreads. These figures highlight how early detection and effective treatment options make prostate cancer far more survivable than pancreatic cancer.
While treatments including chemotherapy, radiation, and in rare situations surgery are available, stage-four pancreatic cancer is still considered largely incurable. The absence of effective early screening contributes to delayed diagnosis, and although a small number of patients, such as Ruth Bader Ginsburg, have lived longer following surgery, these cases are rare. Well-known individuals including Alex Trebek and Aretha Franklin also battled the disease, which remains one of the deadliest cancers in the United States.
Former senator and former University of Florida president Ben Sasse announced on Tuesday, Dec. 23, that he has been diagnosed with terminal stage 4 cancer, as per CNN News.
In the deeply personal message, the former Republican lawmaker from Nebraska described the diagnosis as a “death sentence,” while expressing appreciation for the steady support of his family and close friends.
“I’m fortunate to have incredible siblings and half a dozen friends who are truly like brothers to me. As one of them said, ‘Yes, you’re on the clock, but all of us are.’ Death is a cruel thief, and none of us escape it,” he added.
