Nobody wants to talk about it, and almost everybody deals with it eventually. The heaviness, the bloating, the twenty minutes that accomplish nothing, the whole day feeling faintly off because of it.
There are eleven remedies in this article and most of them genuinely work. But there’s one question worth answering before you try any of them, because it splits this into two completely different problems with two completely different answers.
Has your gut always been like this — or did this start?
If you’ve been on the slow side your whole adult life, the remedies ahead are exactly right. Fiber, prunes, a footstool, a routine. Boring, cheap, effective.
If this is new, the remedies are the wrong place to start. A bowel that worked fine for fifty years and then changed is telling you something, and the answer usually isn’t that you suddenly stopped eating enough lentils. Something changed. Your job is to find out what — and there are two places to look before the produce aisle.
First: Open Your Medicine Cabinet
By far the most common cause of new constipation in adults is a medication. Not diet. Not water. Not age. A drug that’s doing exactly what it’s supposed to do, with a side effect nobody mentioned at the pharmacy counter.
The list is longer than most people expect:
- Opioid painkillers. The heaviest hitter by a distance. Opioids bind receptors in the gut wall directly and bring it to a near standstill — somewhere between 40 and 80 percent of people on regular opioids get constipated, and unlike most side effects, this one doesn’t fade with time. It’s common enough to have its own name — opioid-induced constipation — and its own prescription treatments.
- Iron supplements. Notorious, and often prescribed to exactly the people already struggling.
- Older antidepressants, particularly amitriptyline and its relatives.
- Verapamil, a blood pressure medication, causes constipation in up to a quarter of the people who take it. Other calcium channel blockers do it less, but they do it.
- Antihistamines, especially the older sedating kind.
- Calcium and aluminum antacids.
- Anti-nausea medication like ondansetron.
And the one that’s reshaping this entire picture right now:
GLP-1 medications. Ozempic, Wegovy, Mounjaro, Zepbound. Constipation is one of the most common side effects there is — roughly a quarter of people in the trials — and here’s the part worth understanding: it isn’t really a side effect. It’s the mechanism. These drugs work partly by slowing your stomach and intestines down, which is what makes you feel full for longer. A slower gut is the point. A slower gut also means stool sits in the colon longer, more water gets pulled out of it, and it arrives hard. Millions of people started one of these in the last two years and have no idea their new constipation and their appetite suppression are the same effect.
If your constipation started within a few weeks of starting, switching, or increasing a medication, you’ve probably found your answer — and it’s a conversation with your prescriber, not a bag of prunes. Often there’s a fix: a dose change, a different drug in the same class, or a specific treatment for that specific problem.
Second: Check Your Age Against the Calendar
This is the part where the standard advice is out of date, and it matters.
A persistent change in bowel habits is the single most common early sign of colorectal cancer. Not pain. Not blood, necessarily. Just a bowel that used to behave one way and now behaves another, and stays that way.
Most of the time it’s something else entirely. But this is the situation where “let me try more fiber for six months first” is the genuinely dangerous choice — not because the fiber hurts, but because the six months do.
Screening now starts at 45, not 50. The U.S. Preventive Services Task Force lowered it in 2021, and the reason is worth knowing: colorectal cancer has been climbing steadily in younger adults for two decades. Plenty of articles — including older versions of this one — still say 50. That’s five years out of date, and those five years are the ones the guideline was changed to protect.
If you’re 45 or older and have never been screened, you’re due, regardless of symptoms. The stool-based tests are done at home and mailed in. A colonoscopy is once a decade if it’s clear. Most insurance and Medicare cover screening.
And these send you to a doctor now, not after you’ve tried the remedies:
- Blood in your stool, or stool that looks black and tarry
- Losing weight without trying
- A change in bowel habits that persists — especially after 45
- Stools that have become consistently narrower
- Severe or persistent abdominal pain
- Constipation that doesn’t budge after three weeks of doing the right things
- Feeling like you can never fully empty, every time
None of these means something is seriously wrong. All of them mean the answer isn’t on this page.
So: if it’s new, look at your prescriptions and your calendar first. If it’s just how you are — the eleven that follow are genuinely worth your time, and the most effective one isn’t the one everybody reaches for.
