Thank you for putting up your problem to Healcare Magic!
Four long weeks since passed any motions, are you passing flatus(fart) or not/
If no, then it is an surgical emergency please consult your surgeon.
If yes, then you should start liquid Cremaffin
5ml BD. AND ENSURE GOOD HYDRATION for best results.
If you are having anemia
then you should start iron supplements
as well, 100mg thrice a day.
It would result in black stools and constipation
. So you need to take Cremaffin/Dulcolax
regular for a week and then as required.
I hope this information would be both informative and helpful for you
