I’m a periodontist and academician with a strong clinical and teaching background. Over the last 4 years and 8 months, I’ve been actively involved in dental education, guiding students at multiple levels including dental hygienist, BDS, and MDS programs. Currently, I serve as a Reader at MMCDSR in Ambala, Haryana—a role that allows me to merge my academic passion with hands-on experience. Clinically, I’ve been practicing dentistry for the past 12 years. From routine procedures like scaling and root planing to more advanced cases involving grafts, biopsies, and implant surgeries. Honestly, I still find joy in doing a simple RCT when it’s needed. It’s not just about the procedure but making sure the patient feels comfortable and safe. Academically, I have 26 research publications to my credit. I’m on the editorial boards of the Archives of Dental Research and Journal of Dental Research and Oral Health, and I’ve spent a lot of time reviewing manuscripts—from case reports to meta-analyses and even book reviews. I was honored to receive the “Best Editor” award by Innovative Publications, and Athena Publications recognized me as an “excellent reviewer,” which honestly came as a bit of a surprise! In 2025, I had the opportunity to present a guest lecture in Italy on traumatic oral lesions. Sharing my work and learning from peers globally has been incredibly fulfilling. Outside academics and clinics, I’ve also worked in the pharmaceutical sector as a Drug Safety Associate for about 3 years, focusing on pharmacovigilance. That role really sharpened my attention to detail and deepened my understanding of drug interactions and adverse effects. My goal is to keep learning, and give every patient and student my absolute best.

I am a 2023 batch passout and working as a general physician right now, based in Hanumangarh, Rajasthan. Still kinda new in the bigger picture maybe, but honestly—every single day in this line teaches you more than textbooks ever could. I’ve had the chance to work under some pretty respected doctors during and after my graduation, not just for the clinical part but also to see how they handle people, real people, in pain, in panic, and sometimes just confused about their own health. General medicine covers a lot, right? Like from the smallest complaints to those random, vague symptoms that no one really understands at first—those are kinda my zone now. I don’t really rush to label things, I try to spend time actually listening. Feels weird to say it but ya, I do take that part seriously. Some patients just need someone to hear the whole story instead of jumping to prescription pads after 30 seconds. Right now, my practice includes everything from managing common infections, blood pressure issues, sugar problems to more layered cases where symptoms overlap and you gotta just... piece things together. It's not glamorous all the time, but it's real. I’ve handled a bunch of seasonal disease waves too, like dengue surges and viral fevers that hit rural belts hard—Hanumangarh doesn’t get much spotlight but there’s plenty happening out here. Also, I do rely on basics—thorough history, solid clinical exam and yeah when needed, investigations. But not over-prescribing things just cz they’re there. One thing I picked up from the senior consultants I worked with—they used to say “don’t chase labs, chase the patient’s story”... stuck with me till now. Anyway, still learning every single day tbh. But I like that. Keeps me grounded and kind of obsessed with trying to get better.

Hello Sumit
By going through your history and evaluation of your health status I must say that firstly share your ECG reports with me .
Secondly yes Omega-3s can help reduce inflammation and may support heart health, but the effects can vary based on individual health conditions.
In the meantime: till you share your ECG reports with me kindly
- Focus on getting omega-3s from food sources like fatty fish (salmon, mackerel), walnuts, and flaxseeds, which can be a safer way to incorporate them into your diet.
Thank you

I am a general physician with 8 years of practice, mostly in urban clinics and semi-rural setups. I began working right after MBBS in a govt hospital in Kerala, and wow — first few months were chaotic, not gonna lie. Since then, I’ve seen 1000s of patients with all kinds of cases — fevers, uncontrolled diabetes, asthma, infections, you name it. I usually work with working-class patients, and that changed how I treat — people don’t always have time or money for fancy tests, so I focus on smart clinical diagnosis and practical treatment. Over time, I’ve developed an interest in preventive care — like helping young adults with early metabolic issues. I also counsel a lot on diet, sleep, and stress — more than half the problems start there anyway. I did a certification in evidence-based practice last year, and I keep learning stuff online. I’m not perfect (nobody is), but I care. I show up, I listen, I adjust when I’m wrong. Every patient needs something slightly different. That’s what keeps this work alive for me.

When considering fish oil supplements, particularly for someone with an abnormal heartbeat, it’s essential to balance potential benefits with individual-specific risks. Omega-3 fatty acids, found in fish oil, have been known to have some heart-health benefits, including anti-inflammatory effects and potentially beneficial impacts on heart rate and rhythm. However, the decision to start any supplement, especially in the presence of an abnormal ECG, should be approached with caution. While omega-3s might support general heart health, people with specific cardiac conditions, such as arrhythmias, must consider the nuances of their condition. It’s crucial to discuss this with your healthcare provider, taking the time to go over the specifics of your ECG and any other symptoms or risk factors you may have.
It’s also important to ensure that this step aligns with any treatments you’re currently undergoing. For some arrhythmias, there’s a theoretical risk that high doses of fish oil could potentially affect the heart’s electrical system, so recommendations vary based on the type and severity of the abnormality. In terms of dietary sources, incorporating omega-3 rich foods such as fatty fish (like salmon or mackerel) can be beneficial and is generally considered safe. From a practical standpoint, make sure any decision on supplements doesn’t delay or compromise any prescribed treatments you’re receiving. For general safety, avoiding high doses of supplements without personalized medical advice is advisable. Monitoring doses and maintaining attention to any changes in your condition is vital. If you experience any new symptoms, like palpitations or dizziness, seek medical advice promptly. Ultimately, keep communication open with your cardiologist, who can provide tailored advice based on the full scope of your health profile.

I am a general dentist with 3+ years of working in real-world setups, and lemme say—every single patient teaches me something diff. It’s not just teeth honestly, it’s people… and how they feel walking into the chair. I try really hard to not make it just a “procedure thing.” I explain stuff in plain words—no confusing dental jargon, just straight talk—coz I feel like when ppl *get* what's going on, they feel safer n that makes all the difference. Worked with all ages—like, little kids who need that gentle nudge about brushing, to older folks who come in with long histories and sometimes just need someone to really sit n listen. It’s weirdly rewarding to see someone walk out lighter, not just 'coz their toothache's gone but coz they felt seen during the whole thing. A lot of ppl come in scared or just unsure, and I honestly take that seriously. I keep the vibe calm. Try to read their mood, don’t rush. I always tell myself—every smile’s got a story, even the broken ones. My thing is: comfort first, then precision. I want the outcome to last, not just look good for a week. Not tryna claim perfection or magic solutions—just consistent, clear, hands-on care where patients feel heard. I think dentistry should *fit* the person, not push them into a box. That's kinda been my philosophy from day one. And yeah, maybe sometimes I overexplain or spend a bit too long checking alignment again but hey, if it means someone eats pain-free or finally smiles wide in pics again? Worth it. Every time.

I am an ENT specialist with over 6 years of clincial practice and in this time I have tried to balance hospital work with building my own setup. Currently I work as Consultant at Meridian Hospital Kolathur and also as visiting consultant at VIHAA Hospital Anna Nagar. Along with this I started SCOPE ENT CLINIC in Villivakkam, which is my own space to treat patients with more time n focus. Running a clinic teaches you different kind of responsibility, not only treatment but also trust, making sure patient feels heard and safe. My practice covers a wide range of ENT issues, from common ear infections, sinus problems, throat disorders to more complex surgical cases. I try to focus on giving indiviualised treatment plans, because each patient story is differnt even if the diagnosis sounds similar. Working in multiple hospitals also let me collabrate with other specialities which is important when dealing with complicated ENT cases linked to allergy, pediatrics or even neuro. Founding my own clinic was both challenging and rewarding. Some days are hard, managing staff, handling emergencies, ensuring things run smooth.. but it gave me chance to create an environment where patients get continuity of care. For me ENT is not just about procedures but also education, I try to explain conditions in simple words, guide on prevention and lifestyle changes that can reduce recurrnce. Over these years, what matters most to me is not just how many cases I handled but the connections built with patients and their families. I want to keep growing, keep learning new techniques and stay updated with advances in ENT, but at the same time keep the human touch alive in practice.

I completed my medical degree in 2023, but honestly, my journey in healthcare started way before that. Since 2018, I’ve been actively involved in clinical practice—getting hands-on exposure across multiple departments like ENT, pediatrics, dermatology, ophthalmology, medicine, and emergency care. One of the most intense and defining phases of my training was working at a District Government Hospital for a full year during the COVID pandemic. It was chaotic, unpredictable, and exhausting—but it also grounded me in real-world medicine like no textbook ever could. Over time, I’ve worked in both OPD and IPD setups, handling everything from mild viral fevers to more stubborn, long-term conditions. These day-to-day experiences really built my base and taught me how to stay calm when things get hectic—and how to adjust fast when plans don’t go as expected. What I’ve learned most is that care isn't only about writing the right medicine. It’s about being fully there, listening properly, and making sure the person feels seen—not just treated. Alongside clinical work, I’ve also been exposed to preventive health, health education, and community outreach. These areas really matter to me because I believe real impact begins outside the hospital, with awareness and early intervention. My approach is always centered around clarity, empathy, and clinical logic—I like to make sure every patient knows exactly what’s going on and why we’re doing what we’re doing. I’ve always felt a pull towards general medicine and internal care, and honestly, I’m still learning every single day—each patient brings a new lesson. Medicine never really sits still, it keeps shifting, and I try to shift with it. Not just in terms of what I know, but also in how I listen and respond. For me, it’s always been about giving real care. Genuine, respectful, and the kind that actually helps a person heal—inside and out.

Most of the time YES, omega-3 is safe.
But in some types of arrhythmias, it should be avoided.

I am currently working as a urologist and kidney transplant surgeon at Graphic Era Medical College & Hospital, Dehradun. It's a role that keeps me on my toes, honestly. I handle a pretty wide range of urology cases—stones, prostate issues, urinary tract obstructions, infections, you name it. Some are straightforward, others way more complex than you expect at first glance. Every patient walks in with a different story and that’s what keeps the work real for me. Kidney transplant surgery, though, that’s a whole different zone. You’re not just working on anatomy—you’re dealing with timelines, matching, medications, family dynamics, emotional pressure... and yeah, very precise coordination. I’m part of a team that manages the entire transplant process—from evaluation to surgery to post-op care. Not gonna lie, it’s intense. But seeing someone who’s been on dialysis for years finally get a new shot at life—there’s nothing really like that feeling. In the OR, I’m detail-focused. Outside of it, I try to stay accessible—patients don’t always need answers right away, sometimes they just need to feel heard. I believe in walking them through what’s going on rather than just giving reports and instructions. Especially in transplant cases, trust matters. And clear, honest conversation helps build that. Urology itself is such a misunderstood field sometimes. People ignore symptoms for years because it feels “awkward” or they think it’s not serious until it becomes unmanageable. I’ve had patients who came in late just because they were embarassed to talk about urine flow or testicular pain. That’s why I also try to make the space judgment-free—like whatever it is, we’ll figure it out. At the end of the day, whether I’m scrubbing in for surgery or doing OPD rounds, I just want to make sure what I do *actually* helps. That the effort’s not wasted. And yeah, some days are frustrating—some procedures don’t go clean, some recoveries take longer than they should—but I keep showing up, cause the work’s worth doing. Always is.

Hi,
Fish oil supplements can trigger abnormal heart rhythms, especially in those with arrhythmias.
Not advised unless your cardiologist approves.Food sources are safer than supplements.
