Before, I didn't go to the toilet every day, but I still went often, the stools were soft and easy to pass, but about 3 months ago, I took vitamins containing iron and started to get constipated, the stools were hard and much bigger than usual. , have to push hard every time you go to the toilet. I drank a lot of water and ate vegetables but it didn't help, so I stopped taking the medicine after about 2 weeks of use but the constipation still continued. I have to eat more vegetables than usual, and laxative foods such as bananas and avocados make it easier to go to the toilet, but I can't maintain it regularly and often get apples. Yesterday was 3 days I couldn't go, although I could feel the stool, but because it was big, it couldn't be pushed out, so I had to take a quick laxative to go to the toilet. This situation makes me worry that I don't know what medicine to use for constipation and how to eat it to cure it.
