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 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.

Hello
Yes, there is a good chance your energy can improve if iron deficiency was contributing to the fatigue. Iron supplements usually do not give instant results, but many people start noticing gradual improvement in stamina, weakness, dizziness, and tiredness within 2–6 weeks, while full recovery may take a few months depending on how low the iron levels were.
Metformin itself is commonly associated with low vitamin B12 levels when used for a long time, and B12 deficiency can also cause low energy, weakness, numbness, brain fog, or tiredness. So if you do not feel better after taking iron, it does not necessarily mean recovery will not happen — it may mean another deficiency is present.
Since your kidney and liver function are normal, that is reassuring and makes serious organ-related causes of fatigue less likely. Make sure you are eating properly, staying hydrated, sleeping adequately, and taking iron correctly because absorption matters. Iron is usually absorbed better on an empty stomach or with vitamin C, while tea, coffee, and calcium taken close to it can reduce absorption.
If fatigue continues despite supplementation, getting blood tests such as CBC, ferritin, vitamin B12, HbA1c, and thyroid profile would help identify the exact cause and guide treatment properly.
Take care

I'm Dr. Alan Reji, a general dentist with a deep-rooted passion for helping people achieve lasting oral health while making dental visits feel less intimidating. I graduated from Pushpagiri College of Dental Sciences (batch of 2018), and ever since, I've been committed to offering high-quality care that balances both advanced clinical knowledge and genuine compassion for my patients. Starting Dent To Smile here in Palakkad wasn’t just about opening a clinic—it was really about creating a space where people feel relaxed the moment they walk in. Dental care can feel cold or overly clinical, and I’ve always wanted to change that. So I focused on making it warm, easygoing, and centered completely around you. I mix new-age tech with some good old-fashioned values—really listening, explaining stuff without jargon, and making sure you feel involved, not just treated. From regular cleanings to fillings or even cosmetic work, I try my best to keep things smooth and stress-free. No hidden steps. No last-minute surprises. I have a strong interest in patient education and preventive dentistry. I genuinely believe most dental issues can be caught early—or even avoided—when patients are given the right information at the right time. That’s why I take time to talk, not just treat. Helping people understand why something’s happening is as important to me as treating what’s happening. At my practice, I’ve made it a point to stay current with the latest innovations—digital diagnostics, minimally invasive techniques, and smart scheduling that respects people’s time. I also try to make my services accessible and affordable, because good dental care shouldn’t be out of reach for anyone.

If your kidney and liver function are normal, taking an iron supplement for a short time is unlikely to cause permanent harm, and most mild side effects or fatigue-related symptoms usually improve after stopping or correcting the cause. However, low energy after starting Metformin can also be related to vitamin B12 deficiency, blood sugar changes, or other conditions rather than iron deficiency alone. Please consult an internal medicine specialist or physician for proper blood tests (CBC, ferritin, B12, glucose) and personalized advice.

I am a qualified medical doctor with MBBS and DNB Diploma in Family Medicine from NBEMS, and my work has always been centered on treating patients in a complete, not just symptom based way. During my DNB training I rotated through almost every core department—Internal medicine, Pediatrics, Obstetrics & Gynecology, Surgery, Orthopedics, ENT, Dermatology, Psychiatry, Emergency medicine. That mix gave me the skill to manage acute illness, long term disease and preventive care together, something I find very important in family practice. In psychiatry I worked closely with patients who struggled with depression, anxiety, stress related problems, insomnia or substance use. I learned not just about medication but also about simple psychotherapy tools, psycho education and how to talk openly without judgement. I still use that exp in family medicine, specially when chronic disease patients also face mental health issues. My time in General surgery included assisting in minor and major procedures, managing wounds, abscess, sutures and emergencies. While I am not a surgeon, this gave me confidence to recognize surgical cases early, provide first line care and refer fast when needed, which makes a big difference in online or OPD settings. Now I work as a consultant in General medicine and Family practice, with focus on both in-person and online consultation. I treat conditions like fever, infections, gastrointestinal complaints, respiratory illness, and also manage diabetes, hypertension, thyroid disorders, and lifestyle related chronic diseases. I see women for PCOS, contraception counseling, menstrual health, and children for common pediatric issues. I also dedicate time to preventive health, lifestyle counseling and diet-sleep-exercise advice, since these small changes affect long term wellness more than we often realize. My key skills include holistic diagnosis, evidence based treatment, chronic disease management, mental health support, preventive medicine and telemedicine communiation. At the center of all this is one thing—patients should feel heard, safe, and guided with care that is both professional and personal.

Hello. If your low energy was actually related to iron deficiency, then iron supplements can help improve energy levels gradually. However, metformin itself can also sometimes contribute to fatigue indirectly by causing:
- Vitamin B12 deficiency (quite common with long-term use)
- Gastrointestinal side effects
- Reduced appetite in some people
Since your kidney and liver function are normal, that is reassuring. But before assuming iron deficiency alone, it is important to know whether you truly have:
- Low hemoglobin/anemia
- Low ferritin/iron stores
- Vitamin B12 deficiency
- Poor blood sugar control
- Sleep/stress-related fatigue
Iron supplements usually take:
- A few weeks for noticeable improvement
- 1–3 months to significantly rebuild iron stores if deficiency exists
You should avoid taking iron unnecessarily long term because excess iron can also cause problems if levels are normal.
It would be best to get:
- CBC
- Serum ferritin
- Vitamin B12 level
- Blood sugar/HbA1c
Especially because metformin is more commonly associated with B12 deficiency than iron deficiency.
Final Advice / Prescription:
1. Continue iron supplement only if deficiency is suspected/confirmed
2. CBC, ferritin, and Vitamin B12 testing recommended
3. Maintain balanced diet with protein and green vegetables
4. Proper sleep, hydration, and blood sugar control
5. Physician review if fatigue persists despite supplementation
If the fatigue is due to nutritional deficiency, recovery is very possible once the underlying issue is corrected.
Feel free to reach out again.

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 Pawan
It’s great that you’re being proactive about your health! If your kidney and liver functions are normal and you’re taking iron supplements for iron deficiency, you should start to feel better as your iron levels improve.
Iron supplements can help boost your energy levels, especially if low iron was contributing to your fatigue. Just make sure to take them as directed and keep an eye on any side effects.
Also, it might be helpful to monitor your energy levels and overall well-being over the next few weeks. If you don’t notice any improvement or if symptoms persist, it would be a good idea to consult your doctor for further evaluation.
Thank you

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 Pawan! 💊
Short answer: Maybe, but only if you truly had iron deficiency.
Here’s the catch – and it’s important:
⚠️ Metformin doesn’t cause iron deficiency – it causes Vitamin B12 deficiency
· Low B12 = fatigue, weakness, brain fog – exactly like low iron
· Taking iron without need won’t help, and can cause constipation or stomach issues.
✅ What you should do right now:
· Stop guessing – get blood tests:
🔬 Serum ferritin + Complete blood count (CBC) → checks iron stores
🔬 Vitamin B12 level → the real metformin culprit
· If B12 is low (common after months/years of metformin):
➜ B12 supplements or injections → energy returns in 1–2 weeks
· If iron is low (unrelated to metformin):
➜ Iron supplements → energy returns in 2–4 weeks
👍 Your good news:
Normal kidney + liver function = your body can absorb and use supplements well.
Bottom line: You may recover – but only if you treat the right deficiency.
Don’t waste time. Get B12 and ferritin checked tomorrow.

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.

The recovery of your energy levels after taking iron supplements really depends on whether your low energy is truly due to iron deficiency. Metformin itself doesn’t directly cause iron deficiency, but it can sometimes lead to gastrointestinal changes that might affect nutrient absorption. If you’ve had tests that confirm iron deficiency anemia as the underlying issue for your fatigue, then iron supplements can help improve your energy over time as your iron stores are replenished. This process can take several weeks; typically you might start to notice improvements in symptoms in about a month, assuming your diet supports the absorption of the supplements – consuming Vitamin C-rich foods alongside can aid this. If you haven’t had confirmed iron deficiency, it would be good to have a healthcare provider check your iron levels, because taking iron supplements without need can lead to other issues. Considering you have normal kidney and liver function, supplementing with iron is generally safe, but still, it’s crucial to monitor your response and adjust as needed under the guidance of a healthcare professional. Beyond just checking iron, other causes of fatigue like thyroid issues, vitamin B12 deficiency, or even side effects from metformin should be considered, especially if adjustments in lifestyle or diet haven’t made a difference. If your low energy persists despite taking iron, a follow-up with your doctor would be prudent to explore further diagnostics or other underlying causes, ensuring you’re on the right track for treatment.
