What happens to your gut after 40? Doctor lists 5 major changes, shares tips to manage
Here's what happens to your gut after the age of 40:
1. Slower digestion and metabolism
With age, the rate at which food moves through the digestive tract slows down. This can lead to a feeling of fullness, bloating, or constipation. The decline in muscle tone of the digestive tract and reduced secretion of digestive enzymes means that food takes longer to break down.
How to manage: A fiber-rich diet, adequate hydration, and regular physical activity can help counteract these effects.
2. Decrease in stomach acid (hypochlorhydria)
Stomach acid plays a crucial role in breaking down food and killing harmful bacteria. After 40, many people experience a drop in stomach acid levels, which can lead to indigestion, nutrient deficiencies (especially B12, iron, and calcium), and an increased risk of gut infections.
How to manage: Eating smaller, more frequent meals and fermented foods may help digestion.

3. Gut microbiome imbalance
The diversity and balance of gut bacteria often decline with age, impacting immunity, mood, and digestive efficiency. Antibiotic use, poor diet, and stress can accelerate this imbalance.
How to manage: Probiotics, prebiotic-rich foods (like garlic, onions, bananas), and a plant-based diet can help maintain a healthy microbiome. Also read | Gastroenterologist shares his morning routine for a healthy liver and gut - and why you should try it too!
4. Higher risk of gastrointestinal disorders
Age-related weakening of the gastrointestinal lining can make one more susceptible to issues like acid reflux, diverticulosis, or irritable bowel syndrome (IBS).
How to manage: Regular health check-ups, mindful eating, and avoiding triggers like spicy foods or late-night meals can reduce the risk.
5. Impact of medications and comorbidities
After 40, many individuals begin taking long-term medications for conditions like hypertension, diabetes, or arthritis. These drugs can influence gut motility and flora, sometimes causing constipation or diarrhea.
How to manage: Consulting a doctor about gut-friendly alternatives and using supplements wisely can minimise side effects. Also read | Harvard gut health physician shares 11 science backed tips to eat healthier: 'Don't shy away from eggs'

Hepatologist explains how gut influences memory, mood and mental wellbeing; unpacks why gut may be the ‘second brain'
Several cognitive functions, such as memory, thinking, and concentration, don't just stem from brain activity alone; they are also deeply influenced by gut health. This further demonstrates the importance of gut health in maintaining overall well-being, as it has the ability to influence major functions, including immunity and mental performance. In an interview with HT Lifestyle, Dr Amey Sonavane, consultant hepatology, AHNM, explained how key brain functions are connected to gut health. From memory to concentration, much of the cognitive functions are influenced by gut health. (Shutterstock) ALSO READ: Gastroenterologist shares what your stool's colour, consistency, and frequency tell about your gut health He said, 'Memory and brain function are also closely linked to gut health. The gut sends signals to the brain that affect focus, memory, and even decision-making. When gut bacteria are in poor shape, they can produce chemicals that travel through the bloodstream to the brain, potentially increasing inflammation and contributing to cognitive decline. Some early studies suggest that changes in gut bacteria may appear even before signs of memory loss or Alzheimer's disease show up. This makes the gut an important area to watch, not just for digestion, but for long-term brain health.' Let's take a closer look at the gut-brain axis and explore the fundamentals of this connection, from the microbiome and the chemicals that make the gut the 'second brain' to how your diet can help support this bi-directional relationship. Role of microbiome The microbiome is one of the vital factors at play that form the bedrock of the gut-brain axis, shaping and influencing major cognitive functions and mood regulation. While the gut-brain axis may seem complex, the gut microbiome holds the answers and simplifies it. Dr Amey spoke about the role of microbiome and explained, 'Over the past few years, scientists have discovered something quite remarkable - your gut does a lot more than digest food. Inside your digestive system lives a massive population of bacteria and other tiny organisms, collectively called the gut microbiome. These microorganisms affect how you feel, how your body handles food, and even how your brain works. In simple terms, your gut could be quietly shaping your mood, metabolism, and memory every single day.' Gut is the second brain for mood The roots of your happy moods may be in your gut.(Shutterstock) While cognitive functions like memory, concentration, attention, decision-making, and processing are shaped by gut health, even emotions can be influenced by what's going on in your gut. It signifies the powerful role of gut health, influencing both mind and mood. Dr Amey shed light on the connection to mood regulation and said, 'The gut and the brain are constantly in touch with each other through a network known as the gut-brain axis. In fact, the gut is often called the 'second brain' because it produces many of the same chemicals that your brain does.' 'For example, about 90 percent of your body's serotonin, a chemical that influences mood, is made in the gut. It regulates things like gut motility, secretion, and blood clotting. If the balance of bacteria in your gut is disturbed, it can trigger low moods, anxiety, or even depression. New research shows that improving gut health can actually help some people feel mentally better, giving rise to what are now being called 'psychobiotics', probiotics that support mental health,' he added. Brain-friendly foods Curd in Indian dishes like raita contains good bacteria that help to balance the oral microbiome. (Shutterstock) If the role of gut health in mental wellbeing feels intimidating because it's something that is beyond your conscious control and awareness, but it turns out you can actively take charge and consciously support this gut-brain axis by adding gut-healthy food to your diet. The hepatologist shared some gut-healthy foods and warned against one common habit. Dr Amey suggested, 'Traditional Indian diets actually offer a natural advantage. Fermented foods like curd, buttermilk, dosa, and idli are full of beneficial bacteria. Fruits, vegetables, whole grains, and lentils feed the good microbes in your gut and help keep harmful ones in check. On the other hand, overuse of antibiotics, low-fibre diets, stress, and lack of physical activity can damage the microbiome.'

Jennifer Aniston's rumored boyfriend Jim Curtis kept ‘humiliating' illness hidden for years: What is IBS?
Jennifer Aniston's rumored boyfriend, Jim Curtis, has been battling a health issue that he kept hidden for a long time. The 49-year-old was recently spotted vacationing with Aniston, the Daily Mail reported. Jennifer Aniston's rumored boyfriend Jim Curtis kept 'humiliating' illness hidden for years (jimcurtis1/Instagram) In past interviews, Curtis spoke about the chronic illness that has been affecting his way of life since he was 19. He said that he suffered from acute irritable bowel syndrome (IBS) due to a chronic health condition. In an interview in 2018, he revealed that he often suffered throbbing symptoms while working in high-stress jobs, including on Wall Street. However, he kept his health issues a secret from his friends. He pretended that he walked with a limp or looked unwell because he had been in a motorcycle accident. 'I had IBS, and accidents happened a lot,' Curtis told Fast Company. 'It was humiliating, especially during business trips through crowded airports.' Doctors at major hospitals, including the Mayo Clinic and Johns Hopkins, failed to identify the root cause early on, but Curtis bravely moved forward. He returned to college and worked in health publishing and sales, but mostly kept his illness hidden. The turning point in Curtis' life came when a boss urged him to reveal his struggles. Since then, Curtis began writing self-help books, launching wellness programs, and training in hypnotism. He helped clients like Miranda Kerr and Chrissy Teigen. Curtis now uses his experience to help other people. 'I've helped thousands transform their lives through hypno-realizations,' he said. What is irritable bowel syndrome (IBS)? According to the Mayo Clinic, 'Irritable bowel syndrome (IBS) is a common condition that affects the stomach and intestines, also called the gastrointestinal tract. Symptoms include cramping, belly pain, bloating, gas, and diarrhea or constipation, or both. IBS is an ongoing condition that needs long-term management.' The website adds that only a small number of people suffering from IBS actually have severe symptoms. People often control their symptoms by managing stress, lifestyle and diet. 'More-severe symptoms can be treated with medicine and counseling,' the website says. 'IBS doesn't cause changes in bowel tissue or increase risk of colorectal cancer.'

Yoga at your work desk: Experts suggest 4 quick stretches and 3 ergonomic furniture for better posture
Work often takes up the lion's share of our waking hours, making it difficult to squeeze yoga into the routine. But long hours of slouching at a desk not only strain your back and cramp your neck, they can also snowball into more serious health issues over time. This calls for a balanced approach and a shift in mindset, one where you consciously take out five minutes during work to do yoga, right at your desk. Stretching your body from time to time is important when you are working for long hours.(Shutterstock) Moreover, beyond individual efforts to incorporate yoga at work, workplaces also need to support wellness by creating yoga-friendly spaces, including the use of smart ergonomic furniture. HT Lifestyle reached out to experts who shared how both individuals and organisations can bring yoga into the workplace. ALSO READ: Stress affecting liver health? Yoga expert shares 4 breathing techniques to boost natural detox 5 minutes of yoga at work Long hours of sitting at the desk make it essential to do some desk yoga to ease the strain.(Shutterstock) Generally, the mainstream image of yoga includes a mat and big spaces, but in reality, one doesn't need all that, as there are simple poses that can be done right at the desk. Himalayan Siddhaa Akshar, yoga expert and founder of Akshar Yoga Kendraa, shared with HT Lifestyle how yoga can be done at the work desk. He said, 'If you thought you needed a mat, a big room, a whole hour to be able to reap the benefits of yoga, think again. While an ideal yoga practice needs to be regular and disciplined, you can use many yogic techniques to instantly relieve you from stress and energise your mind and body, even at work.' He recommended some easy yoga poses that you can do in between work: 1. Tadasana: After every couple of hours of sitting at a desk job, stand up and stretch your complete body, interlocking the fingers and lifting full arms over the head, with bodyweight on toes, repeat 5 times. Benefits: This ensures blood flow throughout the system and instantly energises the entire muscular system, re-aligning the body. 2. Greeva Sanchalan Kriya: While seated at the desk, straighten the spine and slowly rotate the neck clockwise, inhaling while going upwards and exhaling while coming down 5-8 times, repeat anticlockwise. Benefits: It releases stress from the neck and shoulders and re-centres the mind. 3. Skanda Sanchalan Kriya: The neck and shoulders hold major stress, especially in seated jobs. Make sure to lengthen the spine, sit straight and do 10 rounds of shoulder rotations, forward and backwards, inhaling while raising the shoulders and exhaling while bringing them down. Benefit: This releases the stress from the entire upper body. 4. Shwaas Dhyaan: While seated comfortably, straighten the spine, eyes closed, and start focusing on the movement of the breath. Inhale for 3 seconds, hold the breath inside for 3 seconds and exhale slowly in 3 seconds. Repeat 5-11 rounds. Benefit: A quick meditation technique to bring the mind to the present and re-focus. Other than these desk stretches, walking also helps beat the stress. The yoga expert explained, 'Whenever possible, take a quick break from the desk, raise both arms upwards and lengthen the spine. Take a short walk at a medium pace around the office campus, if possible outdoors, around nature. A quick round of healing walk after lunch is a great way to stay away from the post-lunch slump.' Workplace furniture that supports yoga Workplace furniture matters as the posture plays an important role in back pain from long hours of sitting.(Shutterstock) Now that you are aware of how to practice yoga individually at work, it's equally important for workplaces to support it by introducing ergonomic furniture that can make yoga a seamless part of the workday. Dr Shubhada Karande, Occupational Therapist and Ergonomic Consultant, Interio, shared with us how organisations can encourage movements and good posture with the help of the right furniture. She said,'As the Indian workplace continues to evolve, employees are spending more time at their desks. Extended hours and sedentary routines often lead to physical strain, poor posture, and rising fatigue. Addressing this requires more than reminders to take breaks; it calls for thoughtful workspace design that makes movement and comfort part of the workday. Yoga, with its focus on alignment, breath and body awareness, offers a practical approach to daily wellness. When combined with ergonomic furniture that enables micro-movements and supports healthy posture, yoga-inspired stretches can be integrated into the work routine without needing extra time.' Dr Shubhada shared 3 workplace furniture which support micro-movement of yoga at work: 1. Height-adjustable desks: Prolonged sitting contributes to stiffness and reduced circulation. Height-adjustable desks promote the micro-movement of the switch between sitting and standing throughout the day. At this type of desk, try the Standing Quad Stretch Pose. This opens and stretches a group of muscles like the quadriceps. This pose is a beautiful combination of strength and balance. Strong quadriceps can help one keep balance in day-to-day activities and ensure safety and stamina in athletic activities. 2. Ergonomic chair: Sitting without support for long periods can lead to back pain and poor circulation. A flexible chair promotes micro movements throughout the work hours, but also provides flexibility when performing stretches while sitting. One can incorporate a Seated Side Bend by sitting upright with feet flat on the floor, raising one arm overhead, and leaning gently to the opposite side. The adjustable height allows for proper posture during both sitting and light stretching. It opens the side body, supports deeper breathing, and reduces tension in the shoulders and spine. 3. Modular desk layouts for open movement: Open modular systems allow better use of space. These layouts make it easier to incorporate small stretches or mindful breathing practices without interrupting work. This reflects the growing focus on collaborative and wellness-oriented office design in India. A simple Standing Spinal Twist beside a modular desk encourages movement between meetings and supports flexibility. Furthermore, Dr Shubhada Karande also shared what furniture types to avoid as they may put more strain on your back. She said, 'Avoid chairs without adjustable flexibility. Don't go for support and static desks either, as they don't allow for height adjustment. Also, avoid extra cushioning for seating that may affect the spine and reduce posture awareness.'
