Hi,
Welcome to HCM,

For constipation never go for purgatives.

Take plenty of fibers in your diet,

Take plenty of green veggies and fresh fruits and juices.

Take plenty of water.

Do abdominal recti muscle exercise for good intestine motility.

Avoid taking Iron if you are taking or if it is necessary then go for good form of iron which does not cause constipation.

Ok and bye.

Dear ..it is a pretty common complaint especially in young adults. Most commonly its just a functional problem, while in others it could be a primarily constipating Irritable Bowel Syndrome (alternating episodes of diarrhea and constipation). As advised by Dr. , you should bring these modifications in your lifestyle. Also, you should try to destressing methods, if required. Do update me if you are taking some other medications as they could be contributing to it. If these methods don't help, please consult MD for ruling out some other disease.
