Hello
I’ve carefully gone through your symptoms — constipation for two months, occasional blood in stool, fissure, weakness, heartburn, and confirmed Vitamin B12 and D deficiency. You’ve explained your condition very clearly, and I must say — you’re already on the right track.
Here’s what’s likely happening:
Constipation & Fissure:
The fissure pain (the “thorn-like” sensation) and bleeding are due to hard stools. Even after bleeding stops, the fissure takes time to heal completely — if constipation persists, it can reopen.
Vitamin Deficiencies:
Low B12 (170 pg/ml) and Vitamin D (27 ng/ml) can cause fatigue, nerve tingling, mood changes, and delayed recovery. These deficiencies often coexist with poor gut absorption and diet imbalance.
Weight loss (3 kg in 20 days) with persistent heartburn and gas needs further evaluation — especially to rule out gastritis, malabsorption, or stress-related gut dysfunction.
Here’s what I recommend:
Continue Vitamin D for 8 weeks (weekly dose if prescribed).
Start Vitamin B12 supplement (Neurobion Alpha D or methylcobalamin) for at least 3 months — no need to wait for multivitamin completion.
Take a soft stool regimen:
Isabgol husk or lactulose syrup at night
Plenty of water (2.5–3 L/day)
Fruits like papaya, soaked raisins, and vegetables daily
Avoid spicy food, caffeine, and heavy meals to ease acidity.
If weight continues to fall or fatigue worsens, we may need a stool test, Hb, and ferritin to assess nutrition and gut function.
You’re dealing with a treatable combination of issues — once constipation and deficiencies are corrected, energy and digestion improve quickly.
If you’d like me to review your complete reports and guide you step-by-step with diet, medicines, and recovery tracking, you can message me directly on WhatsApp —nine three two six zero two zero five three six — for a private consultation.
I’ll personally help you correct the deficiencies and heal your gut naturally and safely.

Hello, I am Dr. Romain Rajan, General Physician. Your case has been allotted to me.
I understand your concern. Constipation with fissure pain, gas, and weakness can become distressing, especially when associated with vitamin deficiencies. These symptoms are quite common when digestion slows down and nutritional absorption is affected.
â
Advices
Drink 3 to 3.5 liters of water daily, include warm water after waking up and before sleeping.
Add high-fiber foods such as papaya, soaked raisins, banana, oats, and vegetables daily. Avoid spicy or fried food that worsens fissure pain and acidity.
As an expert suggestion, take 1 tablespoon of isabgol (psyllium husk) with warm water at night; it helps regulate bowel movement naturally.
What to Monitor
Note your stool pattern, any recurrence of bleeding, or pain during defecation.
Watch for persistent heartburn, bloating, or fatigue despite taking supplements.
Management
You may continue your Vitamin D course and start Vitamin B12 supplementation (like Neurobion Alpha D) as advised. It can be taken together safely with Vitamin D. Do not wait for one course to finish. Continue multivitamin if prescribed. For constipation, you can use a stool softener such as Cremaffin Plus at bedtime for a few days. Avoid overuse.
When to Consult a Doctor Immediately
If you notice fresh blood again or severe anal pain.
If constipation persists despite dietary changes and stool softener use.
If weakness increases or you feel dizzy, faint, or have black stools.
Every patientâs situation is unique. For accurate diagnosis and lasting relief, itâs important to discuss your medical history and symptoms in detail.
ð You can reach out to me directly for this case, and also connect with me in future for any medical consultation.
I am available on Practo or on WhatsApp at 85271646 seven seven for a one on one consultation, where youâll receive
A personalized treatment plan
Safe medicine adjustments (if required)
Quick follow ups to track your recovery
Take care, wishing you good health.
Best regards,
Dr. Romain Rajan

For constipation - Take high fibre diet. Add salads to your meal. You can take 1 heaped spoon of Psyllium Husk mixed with a glass of water in the morning.
For Vit B12 and Vit D deficiency - Continue the vitamin supplements. If you're not strictly vegetarian, add meat to your diet.
Health Tips
For now, try to avoid spicy foods as they can aggravate the fissure.

The chronic constipation and passage of hard stools have caused fissure. Bleeding stopped means mostly the fissure would have healed but has high probability that it can reccur if constipation is not dealt with.
Since you are already on another vit d supplements, take tab. Neurobion alpha only (note that it is without vit d in content).
Next Steps
Have a diet with fruits, vegetables. Avoid meat.
Stool softeners: Syp. Lactulose 15ml HS x 1 week
Stay hydrated

It looks like your constipation and fissure are linked to vitamin deficiencies and mild digestive slowdown. The fissure causes pain and bleeding when stools are hard or irregular, which often leads to fear of passing stool and worsens constipation.
Your vitamin B12 level of 170 is quite low and can cause weakness, fatigue, and even digestive issues. Vitamin D at 27 is also below the ideal range and may add to muscle tiredness and low energy. The gas and heartburn suggest slow digestion, often worsened by low fiber intake or irregular meals.
You should continue your vitamin D course as prescribed. You can safely start a vitamin B12 supplement like Neurobion Alpha D now; there is no need to wait for a month. Drink plenty of water, add fiber from fruits, vegetables, and a teaspoon of isabgol at night. Avoid spicy or fried food for a few weeks.
Once your digestion settles and vitamin levels improve, the weakness and constipation should ease. For clarity and proper management, an online consultation with me will help.

Most multivitamin tablets already contain Vitamin B complex So you don’t need to take a separate B12 tablet and
If you want both Vitamin B and Vitamin D together, you can simply take Neurobion D. This already has both vitamins, so you don’t need extra tablets.
Next Steps
drink plenty of water 8-12 glass per day
fiber rich food,
try 1tsp isabgol with lukewarm water before sleeping
