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 It’s good to hear that your hemoglobin levels were normal, but low vitamin B12 and D3 can definitely impact your overall health and energy levels. Here’s how you can address these deficiencies:

### Vitamin B12 1. Dietary Sources: Include more B12-rich foods in your diet, such as: - Dairy products (milk, cheese, yogurt) - Eggs - Meat (especially liver and fish) - Fortified cereals and plant-based milk

2. Supplements: If dietary changes aren’t enough, consider taking a B12 supplement. Speak with your healthcare provider about the right dosage for you.

3. Regular Monitoring: Since B12 deficiency can lead to anemia and neurological issues, keep monitoring your levels regularly.

### Vitamin D3 1. Sun Exposure: Try to get some sunlight exposure, as your body produces vitamin D when your skin is exposed to sunlight. Aim for about 15-30 minutes a few times a week, depending on your skin type and local climate.

2. Dietary Sources: Include foods rich in vitamin D, such as: - Fatty fish (salmon, mackerel, sardines) - Fortified foods (like milk, orange juice, and cereals) - Egg yolks

3. Supplements: If your levels are significantly low, a vitamin D supplement may be necessary. Again, consult your healthcare provider for the appropriate dosage.

### Follow-Up - Recheck Levels: After making dietary changes or starting supplements, recheck your B12 and D3 levels in a few months to see if they have improved.

- Consult a Doctor: If you have any symptoms related to these deficiencies (like fatigue, weakness, or bone pain), it’s important to discuss them with your healthcare provider.

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.

Hsllo, thank you for sharing your concern. A normal hemoglobin (14.9) is reassuring, but it is still possible to have significant Vitamin B12 and Vitamin D3 deficiency even when CBC/hemoglobin are normal.

Low B12 can cause symptoms such as: - numbness/tingling, - burning feet, - fatigue, - brain fog, - imbalance, - mood changes, - or nerve irritation.

Low Vitamin D can contribute to: - body pain, - muscle weakness, - fatigue, - low mood, - or bone discomfort.

Since you also mention gastrointestinal problems, absorption issues could contribute to low B12 levels even if your diet includes meat/dairy. Limited sunlight exposure is also a very common reason for low Vitamin D.

What is usually recommended: - Continue appropriate B12 and Vitamin D supplementation - Recheck levels after treatment - Address any underlying gut/absorption issue if symptoms persist

Depending on the severity of deficiency, doctors may prescribe: - Oral supplements, - or sometimes injections for B12 if levels are very low or absorption is poor.

Lifestyle measures: - Regular sunlight exposure (morning sunlight when possible) - Protein-rich balanced diet - Avoid excessive junk/alcohol if applicable

Seek medical review sooner if you develop: - worsening numbness, - weakness, - walking difficulty, - severe fatigue, - memory changes, - or persistent neurological symptoms.

Final Advice: 1. Continue prescribed Vitamin B12 and Vitamin D supplementation 2. Repeat B12/D3 levels after treatment course as advised 3. Adequate sunlight exposure when possible 4. Evaluation of gastrointestinal condition if deficiencies keep recurring 5. Physician review if neurological symptoms persist

Advice: Low B12 and D3 deficiencies can occur even with a normal hemoglobin level, and they commonly improve with proper supplementation and correction of absorption/lifestyle factors.

Feel free to reach out again.

Regards, Dr. Nirav Jain MBBS, D.Fam.Medicine

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.

Based on the information you’ve shared, it sounds like your hemoglobin levels were normal, but you have deficiencies in vitamin B12 and vitamin D3. These deficiencies can impact your health in various ways. Vitamin B12 deficiency can lead to anemia, fatigue, neurological changes, and other health issues. Vitamin D3 is crucial for bone health, immune function, and overall well-being. To address these deficiencies, here are some steps you can take: First, consider dietary changes. For vitamin B12, focus on incorporating foods like meat, fish, dairy, and eggs into your diet, as these are rich sources of B12. If you’re vegetarian or vegan, fortified cereals and plant milk can be alternatives. For vitamin D3, fatty fish, liver, and egg yolks are good sources, along with fortified foods. You might also consider getting more sunlight exposure, as sunlight helps your body synthesize vitamin D. However, supplementation is often necessary, particularly if absorption is an issue or diet alone isn’t sufficient. It’s best to discuss with your healthcare provider about the right dosage for your specific needs based on the results of your blood test. They might recommend B12 injections or high-dose vitamin D3 supplements for quicker replenishment. Monitoring your levels with follow-up blood tests can be useful to assess the effectiveness of your regimen. It’s also important to evaluate if there’s an underlying issue affecting absorption, such as gastrointestinal conditions or medication interactions. If you notice symptoms like numbness, tingling, severe fatigue, or balance problems, seek further medical advice promptly as these might indicate a more urgent need for correction. Always ensure any new supplements fit into your overall health management plan to avoid unnecessary interactions.

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

A normal hemoglobin (14.9) is reassuring, but you can still have significant deficiencies of both Vitamin B12 and Vitamin D3 even when the CBC looks normal.

Since you are having numbness/tingling and also have gastrointestinal issues, the low B12 is important because B12 deficiency can affect nerves before anemia appears.

Possible reasons include:

* poor absorption from GI conditions, * low stomach acid, * long-term acid reflux medicines, * low sunlight exposure (for D3), * or inadequate absorption despite diet.

What you should do:

Vitamin B12

* Continue supplementation regularly. * Depending on how low the level was and your symptoms, doctors may recommend: * high-dose oral B12, * or B12 injections if absorption is poor. * Foods that help: * eggs, * dairy, * fish, * meat.

Vitamin D3

* Continue Vitamin D3 supplementation as prescribed. * Safe sunlight exposure (morning/evening sunlight for ~15–30 minutes several times weekly) may help if possible. * Calcium intake should also be adequate.

Important follow-up

Because symptoms are continuing, it would be reasonable to repeat:

* B12 level, * Vitamin D level, * CBC, * and sometimes iron/folate/thyroid testing.

If numbness worsens, balance problems develop, weakness appears, or symptoms persist despite supplements, you should see a physician because prolonged Vitamin B12 Deficiency can sometimes cause nerve complications that need more aggressive treatment.

GI disorders can make oral absorption difficult, so your doctor may decide whether injections are more suitable for you.

Take care Feel free to talk
