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.

For years, the word "cancer" filled people with fear. Many still believe that a cancer diagnosis means the end. As an oncologist practicing in a Tier-2 city, I see every day that this is no longer true.

With early detection and modern treatment, cancer is now often curable. And the best part: you no longer need to travel to metros to get world-class care.

Why Early Detection Saves Lives

Cancer found early is cancer that can be treated easily.

- Breast cancer detected early has a survival rate of over 90%

- Cervical cancer can be prevented with a simple HPV vaccine and regular screening

- Oral, colon, lung, and prostate cancers also respond far better when caught before they spread

The problem: Most patients still come to us when symptoms become severe.

My request to you: Don’t wait. If there is a lump, persistent cough, bleeding, or unexplained weight loss for more than 2-3 weeks, please see a doctor. A 15-minute screening can add years to your life.

Tier-2 Cities Are No Longer Behind

Earlier, patients from smaller cities had only two options: travel repeatedly to big metro hospitals or settle for limited local treatment. Both were exhausting.

That has changed.

Today, most Tier-2 cities now have comprehensive cancer centers with:

CT/MRI/PET scans, advanced pathology labs, chemotherapy daycare, radiation therapy, and experienced cancer surgeons.

This means diagnosis, surgery, chemotherapy, immunotherapy, and follow-up can all happen close to your home, with family support and at a lower cost.

Treatment Today Is Smarter, Not Just Stronger

Chemotherapy is still important, but it’s no longer the only option.

1. Targeted Therapy: Medicines that attack only cancer cells based on genetic testing. Fewer side effects.

2. Immunotherapy: Boosts your own immune system to fight cancer. Giving great results in lung cancer, kidney cancer, and blood cancers.

3. Advanced Radiation: Delivers precise radiation to the tumor while protecting healthy organs.

4. Minimally Invasive Surgery: Keyhole and robotic surgeries mean smaller cuts, less pain, faster recovery. Even elderly patients can now safely undergo surgery.

Let’s Break 3 Dangerous Myths

Myth 1: "Cancer always causes pain in the beginning"

Fact: Most early cancers are painless. Don’t wait for pain.

Myth 2: "Surgery makes cancer spread"

Fact: This is false. Surgery is often the most curative treatment when done on time.

Myth 3: "Alternative therapies can cure cancer"

Fact: Diet, yoga, and wellness help with strength and side effects. But they cannot replace doctor-prescribed treatment. Delaying proven treatment reduces your chances of cure.

A Message Of Hope

A cancer diagnosis will change your life, but it does not have to end it. Across Tier-2 India, I am seeing patients go back to work, celebrate birthdays, and live full lives after cancer.

The key is 3 things: Awareness, Early Check-ups, and Trusting Modern Medicine. If you or a loved one has symptoms, please consult an oncologist early. Treatment closer to home is now possible, effective, and affordable. Cancer can be fought. And it can be won.

It's just July, and Mumbai’s monsoon has been swinging from tumultuous to alarmingly parched. When the climate shifts with such volatility, it’s bound to have an impact on your overall health.

From dehydration risk to chances of gastrointestinal infections, here’s how rapidly changing weather can take a toll on your mental health.

Impact Of Extreme Weather On Health

Respiratory Effects

HealthandMe spoke to Dr. Abizer Manked, Consultant Physician and Diabetologist at Saifee Hospital, Mumbai. One of the health impacts extreme weather has is on the respiratory system. Due to the increase of irritants and allergens, several respiratory issues can be triggered.

Dr Manked says, “The temperature and humidity can irritate our airways. This can trigger asthma, bronchitis, and allergies. It can also trigger coughing, giving us throat infections, and making it harder to breathe. This is especially true for people who already face breathing problems.”

Allergy Triggers

The expert says that allergy episodes increase significantly during the monsoon, especially when the rain is inconsistent. An increase in humidity paves the way for mould and fungi growth, which can make allergies worse.

Cold And Flu-Like Symptoms

When temperatures and humidity change rapidly, our immune response can take a hit. It can lead to frequent episodes of common cold, cough, and other flu-like symptoms.

“When the weather changes quickly, it can also make us more likely to get infections like the common cold and flu. The weather itself does not make us sick. The sudden change can affect our body’s ability to fight off infections. When we are indoors with a lot of people during the rain, viruses spread easily,” Dr Manked explains.

Heat Exhaustion And Dehydration

When a heavy rain episode is followed by hot and humid weather, it can lead to increased risk of heat-related illnesses.

Dr Manked says, “The humidity makes it hard for our bodies to cool down. This can make us tired, give us headaches, and leave us dehydrated more frequently. It can even lead to heat exhaustion. This especially holds true for people who work outside or spend a lot of time in the sun.”

Viral And Parasite Infections

In the monsoon, Mumbai sees the highest number of cases of viral and parasite infections like dengue and malaria.

Flooding and waterlogging create breeding hotspots for mosquitoes, which can lead to more chances of infections. Poor hygiene and maintenance of surroundings further increase the risk.

Fungal Infections

Staying in damp clothes and shoes for long periods increases the risk of contracting fungal infections. The expert says it’s crucial to keep one’s clothes dry to avoid the riks of skin infections.

How To Protect Yourself From Weather Changes?

Simple precautions can go a long way in reducing health risks during an irregular monsoon:

  • Drink clean, safe water, and avoid consuming food exposed to floodwater.
  • Wash hands regularly with soap, especially before eating.
  • Avoid walking through floodwater whenever possible.
  • Wear waterproof footwear if you must step into waterlogged areas.
  • Keep homes dry and well-ventilated to reduce mold growth.
  • Empty containers that collect rainwater to prevent mosquito breeding.
  • Stay hydrated even if the weather feels cooler.
  • Change out of wet clothes promptly and dry your feet thoroughly.
  • Seek medical attention if you develop persistent fever, severe diarrhea, breathing difficulties, or symptoms after exposure to floodwater.

Children, older adults, and people with asthma, diabetes, high blood pressure, obesity, and other chronic illnesses are more likely to face these health effects during the monsoon. It is, therefore, crucial to take extra precautions and care for those with a weakened immune system.

When you hear the term plastic surgery, what comes to mind first? For many people, it's cosmetic enhancements such as facelifts, rhinoplasty, or body contouring. However, experts say this is one of the biggest misconceptions about the specialty.

Marking World Plastic Surgery Day on July 15, specialists highlighted that plastic surgery is far more than improving appearance. While cosmetic surgery focuses on enhancing aesthetics, reconstructive plastic surgery is dedicated to restoring form and function after injuries, burns, cancer, or congenital conditions.

Originally launched as National Plastic Surgery Day by the Association of Plastic Surgeons of India (APSI) in 2011, the observance was adopted globally by international plastic surgery societies in 2021.

The theme for World Plastic Surgery Day 2026 is "Changing Lives with Plastic and Reconstructive Surgery."

Plastic Surgery and Cosmetic Surgery Are Not the Same

Speaking to HealthandMe, Dr. Deepak K. L. Gowda, Senior Consultant – Aesthetics, Plastic Surgery & Reconstructive Surgery at SPARSH Hospital, said plastic surgery is a broad medical specialty, while cosmetic surgery is only one of its subspecialties.

Cosmetic surgery is performed to improve the appearance of otherwise healthy and functional body structures. Reconstructive plastic surgery, on the other hand, aims to restore appearance and function following injury, disease, cancer surgery, burns, or congenital defects.

According to Dr. Gowda, reconstructive procedures account for more than 75% of plastic surgery practice, while cosmetic procedures make up a comparatively smaller proportion. However, the growing popularity of aesthetic treatments has led many people to wrongly assume that plastic surgery is only about beauty enhancement.

Common Cosmetic Procedures

Cosmetic surgery is designed to enhance physical appearance in individuals whose body structures function normally. Some of the most commonly performed procedures include: breast augmentation, rhinoplasty (nose reshaping), facelifts

and dermal fillers and more.

When Is Reconstructive Plastic Surgery Needed?

Reconstructive plastic surgery helps restore both appearance and function after illness, injury, or trauma. Common procedures include:

  • Breast reconstruction after cancer surgery
  • Burn reconstruction
  • Cleft lip and palate correction
  • Reconstruction of congenital limb abnormalities
  • Hand surgery
Dr. Gowda advised people with burns, injuries, congenital disorders, cancer-related tissue loss, or diseases affecting the skin, muscles, nerves, or soft tissues to consult a plastic and reconstructive surgeon as early as possible, as timely treatment can significantly improve outcomes and expand treatment options.

Seven Questions To Ask Before A Cosmetic Procedure

Dr. Chintan Gujarati, Cosmetic and Plastic Surgeon at Ruby Hall Clinic, told HealthandMe that cosmetic procedures can enhance appearance and boost confidence, but they should always be approached with careful planning and informed decision-making.

He recommended asking these seven questions before undergoing any cosmetic procedure:

1. Is the procedure right for me?

Discuss whether the treatment is suitable for your health, goals, and individual needs.

2. Is my surgeon qualified?

Ensure the procedure is performed by a board-certified plastic surgeon or a trained specialist with relevant experience.

3. What are the risks?

Understand possible complications, including infection, scarring, or the need for additional treatment.

4. What results can I realistically expect?

Cosmetic procedures can improve appearance, but they cannot guarantee perfection.

5. What is the recovery process?

Ask about downtime, pain management, activity restrictions, and when you can safely return to your routine.

6. What will the procedure cost?

Request a detailed breakdown covering consultation fees, hospital charges, medications, and follow-up visits to avoid unexpected expenses.

7. What if I am unhappy with the results?

Discuss revision policies and available corrective options before making a decision.

Making an Informed Decision

Experts emphasized that choosing to undergo a cosmetic procedure is a personal decision that should be based on realistic expectations, qualified medical advice, and a clear understanding of the benefits, risks, recovery process, and overall costs.

They also stress that plastic surgery extends well beyond aesthetics, with reconstructive surgery continuing to play a vital role in restoring both function and quality of life for patients affected by injury, disease, or congenital conditions.
