Chronic constipation

Is there really no way to get rid of this annoying constipation?

My symptoms have worsened compared to before. In the past, even with constipation, I only felt a bit heavy, but these days my stomach is so bloated, I feel like I might vomit, and I have a lot of pain in the area called pectus excavatum. If I don't have a bowel movement for just 2-3 days, I become very distressed with these symptoms.

A few months ago, I also had a colonoscopy, but they couldn't find the cause. All I was told was to try improving my lifestyle habits.

I think I've tried everything that's supposed to be good for constipation. My husband always says that if he had saved all the money he's spent on constipation remedies, he could have bought a house, but that's a bit of an exaggeration.

I drink at least 2 liters of water daily because it's good for constipation, eat a lot of vegetables, and walk about ten thousand steps regularly, but I still feel really sad.

Are these various causes the reason for constipation? Is the cause that applies to me old age? Haha

Please share your advice for those who have overcome chronic constipation. I want to live happily after a good bowel movement~~~ Please~~~
