You have hypothyroidism, but your attached report shows
TSH 1.29 with normal T3/T4, which means your
thyroid levels are well controlled on your current dose (62.5 mcg thyroxine).
So your constipation now is not due to uncontrolled thyroid, but more likely chronic functional constipation, which has unfortunately led to anal fissure and sentinel tag.
Yes , you can safely take lactulose 15 ml daily. It is a gentle, non-habit forming stool softener and is commonly used long-term in such cases. You can even adjust the dose (10–20 ml) based on response to achieve soft, daily stools.
Next Steps
1. Continue lactulose daily, preferably at night
2. Aim for soft stool consistency (not hard, not watery)
3. Add osmotic + bulk approach if needed: lactulose + isabgol (psyllium)
4. For fissure:
-Sitz bath (warm water) 10–15 min, 2–3 times/day
-Local application (e.g., lidocaine + nifedipine/diltiazem ointment)
-Maintain regular bowel timing, don’t delay urge
Health Tips
-Even with good diet, some people need long-term stool softeners, that’s okay
-Avoid straining at all costs (this worsens fissure)
-If constipation still persists, consider evaluation for slow transit or pelvic floor dysfunction
-If fissure pain/bleeding continues then consult a surgeon (for medical management, rarely surgery)
You’re already doing most things right, just need consistent stool softening and fissure care, and things usually settle well over time.
