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?

Microorganisms, or microbes, reside in various parts of your body, but the majority are concentrated in the intestines, particularly in the cecum, a part of the large intestine. This collection of microbes is referred to as the 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.

Cigarettes And The Female Body: The Hormonal Toll We Don’t Talk About

Updated Mar 25, 2026 | 06:00 PM IST

SummaryWhile smoking is often viewed through a male lens, women comprise about 20% of the more than 1 billion smokers globally, and the biological toll they pay is unique. One of the most overlooked victims of tobacco is the endocrine system, especially in women.

Smoking is injurious to health.” We see this warning in theatres and on billboards, but for many, it’s become background noise. We tend to think of smoking as a “future threat”, a cough, some breathlessness, or perhaps a scary diagnosis years down the line.

But did you know that the cigarette in your hand is also quietly sabotaging something far more immediate: your hormonal health.

The Gender Gap In The Smoke

While smoking is often viewed through a male lens, the reality is shifting. In fact, approximately, women comprise about 20% of the more than 1 billion smokers globally, and the biological toll they pay is unique.

Usually the impact of smoking is focused more on the lungs and the heart. But one of the most overlooked victims of tobacco is the endocrine system, especially in women.

A Direct Hit To Your Menstrual Cycle

Cigarette smoke is a cocktail of thousands of toxic chemicals, including tar, nicotine, carbon monoxide, and poisonous metals. These don't just stay in the lungs; they hijack the hypothalamic–pituitary–ovarian (HPO) axis, which is the delicate "command center" that regulates your period.

Nicotine triggers a surge in stress hormones like cortisol and catecholamines. When these are chronically elevated, they disrupt the steady, rhythmic release of hormones that tell your body when to ovulate. The result?

  • Irregular or Shorter Cycles: Your body’s natural rhythm is thrown off-beat.
  • Painful Periods (Dysmenorrhea): Nicotine narrows your blood vessels (vasoconstriction), reducing blood flow to the uterus and making cramps significantly more intense.

The Effect of Smoking On Estrogen

Estrogen is the powerhouse hormone responsible for regulating the menstrual cycle, maintaining bone density, protecting heart health, and much more.

Smoking acts as an "anti-estrogen." By draining your estrogen, smoking can trigger early menopause, often by one to two years, and increase your long-term risk of osteoporosis.

For those trying to conceive, the toxins reduce your "ovarian reserve" by 20% (your egg count), making the journey to motherhood much harder.

The Road To Recovery: Recalibrating Your System

But the good news? Our bodies are remarkably resilient. Within weeks of quitting, your circulation improves, stress hormones stabilize, and your endocrine system begins to regain its equilibrium.

Many patients report more predictable cycles and less painful periods after quitting smoking.

Don't Rely On Willpower Alone

Quitting is a medical challenge, not just a test of character. If you’re overwhelmed, connect with your doctor on using the many tools available that can help you in quitting, such as:

  • Nicotine Replacement Therapy (NRT): Gums, patches, and lozenges provide controlled nicotine without the toxic smoke. Unlike smoking, which delivers nicotine in rapid spikes along with thousands of harmful substances, NRT helps reduce cravings and supports quitting with far less harm.
  • Prescription Support: Medications reduce the "reward" your brain gets from nicotine.
  • Behavioral Support: Counselling significantly increases your chances of staying smoke-free for good.

Your hormones work tirelessly every single month to keep your body in harmony. Every cigarette disrupts that dance; every "no" helps restore it.

Your body’s natural rhythm is worth protecting. Perhaps today is the day you finally return the favor.

Dhurandhar 2 actor Mustafa Ahmed, who played Rizwan in the film, opened up about growing up with dyslexia. He shared that he struggled with reading and writing, but sports and dancing came naturally to him.

"I was not a bright kid. I was dyslexic and came from an Afghan background. But I was always physical, I was good at sports, and I picked up dancing naturally. Anything that involved using my body, I was good at it,” said Mustafa, who trained has Hrithik Roshan, in the Alpha Coach podcast.

What Is Dyslexia?

Dyslexia is a learning difficulty that affects reading, writing, and spelling. However, it has nothing to do with intelligence.

Common signs of dyslexia include:

  • Difficulty reading or recognizing words
  • Trouble with spelling and writing
  • Confusing similar-looking letters (like b/d or p/q)
  • Slow reading speed and poor comprehension
  • Difficulty following written instructions

This means that children with dyslexia are simply wired differently and may need to focus on other learning areas.

How Did Mustafa Overcome Dyslexia?

Mustafa did exactly that. He focused on training hard and eventually worked with big stars like Hrithik Roshan. That’s when he caught the attention of Aditya Dhar, the maker of Dhurandhar. Aditya saw potential in him and encouraged him to pursue acting, helping launch his journey in the industry.

Growing up, Mustafa, who revealed in an interview, faced challenges in school due to his learning difficulties. Tasks like reading scripts or memorizing lines may not have come easily at first. However, with determination, support, and self-belief, he was able to overcome these barriers.

However, today as a rising star, his story is a reminder that with the right support, early diagnosis, and self-belief, children with dyslexia can truly thrive.

Signs and symptoms of dyslexia

Doctors say signs of dyslexia can look different at each age. It happens because your brain grows and learns in new ways as you get older. You may notice your child has:

  • Has difficulty learning or recognizing letters
  • Has trouble rhyming words
  • Mixes up words that sound similar
  • Find it difficult to read simple words after learning letter sounds
  • Have trouble remembering letters, even after lots of practice
  • Avoiding tasks that have to do with reading
  • Feeling sick or anxious before school or homework time
  • Struggling in school

Can You Treat Dyslexia?

Doctors say even though dyslexia is a lifelong condition, it can be effectively managed with the help of interventions like:

  • Phonics-based reading programs
  • One-on-one tutoring
  • Speech and language therapy
  • Use of assistive technology like audiobooks and text-to-speech tools

With these strategies, individuals with dyslexia can improve their reading skills and excel in their chosen fields.

Mel Schilling Dies At 54, Her Colon Cancer Spread To Her Brain

Updated Mar 25, 2026 | 12:45 PM IST

SummaryMel Schilling, 54, died after colon cancer spread to her brain. Diagnosed in 2023, she showed resilience through treatment. Experts explain cancer can spread via blood or lymph, forming new tumors in distant organs.

Mel Schilling, an Australian psychologist and a dating expert died at 54. Her husband Gareth Brisbane announced the death in a social media statement.

What Happened To Mel Schilling?

Schilling was diagnosed with colon cancer in December 2023. Just two weeks ago she said that the disease had spread to her brain. "I honestly don't know how long I have left," she wrote.

According to her husband, she died "peacefully, surrounded by love". “This is a woman who, through two years of chemotherapy, when she could barely lift her head from the pillow, never complained and never stopped showing courage, grace, compassion and empathy, and never missed a day of filming,” Brisbane wrote.

She was also an expert on 'Married at First Sight Australia' for 12 years and because of her illness she stepped down as a dating expert.

How Does Cancer Spread To Other Parts Of The Body?

Schilling said that her cancer had spread to her brain. as per the Cancer Research UK, cancer cells can spread to other parts of the body through bloodstream or lymphatic system. They can then start to grow into new tumors. The National cancer Institute notes that cancer cells spread through the body in a series of steps, which include:

  • growing into, or invading, nearby normal tissue
  • moving through the walls of nearby lymph nodes or blood vessels
  • traveling through the lymphatic system and bloodstream to other parts of the body
  • stopping in small blood vessels at a distant location, invading the blood vessel walls, and moving into the surrounding tissue
  • growing in this tissue until a tiny tumor forms
  • causing new blood vessels to grow, which creates a blood supply that allows the metastatic tumor to continue growing

What Is Colon Cancer?

Colon (colorectal) cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.

As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.

Colon cancer poses serious health risks because cancerous cells can invade healthy tissues. Over time, they may break away and spread to other parts of the body, making detection more difficult since the symptoms can resemble other conditions.

How Can You Get Screened For Colon Cancer?

You can get examined by a colonoscopy. A colonoscopy is a 15 to 60 minute medical procedure that is used to examine the entire inner lining of the large intestine, which includes rectum and colon for abnormalities, such as polyps, inflammation, or cancer. A doctor uses a colonoscope, which is a thin, flexible tube with a camera to take images, remove polyps, or take issue samples.

Most health experts, including federal guidelines and the American Cancer Society, recommend that people at average risk for colorectal cancer start screening at age 45. This usually means getting a colonoscopy once every 10 years, or opting for stool-based tests every one to three years. These guidelines also play a role in whether insurance companies cover the tests.
