Constipation happens. We ignore it until the pipeline shuts down.
Fiber. Water. We are told this fixes everything.
It usually helps. But what if it does nothing?
“Constipation is extremely common.”
Dr. Ketan Thanki
He’s a colorectal surgeon in California. He says almost everyone gets stuck at some point.
As we age the risk gets worse. If symptoms linger for three months or more it is chronic. If fiber and hydration fail consider what else might be wrong.
You Are Exhausted
Sleep matters more than you think.
Insomnia raises constipation risk. So does poor sleep quality.
Dr. Stephanie A. McAbee notes that sleep deprivation breaks the colon’s rhythm. Your gut follows a 24-hour clock. It works hard in the morning. It rests at night.
Messing up the sleep schedule throws that cycle out of whack.
Then there is cortisol. Dr. Jeremy Polman explains that lack of sleep spikes stress hormones. High cortisol equals constipation.
It is not just physical fatigue. The gut-brain axis takes a hit too.
Your Allergy Meds Are Sabotage
Antihistamines are common. Many have anticholinergic side effects.
This means they suppress the parasympthetic nervous system. Less digestion.
Gut motility slows down.
“These effects can also include dry mouth.”
It is not true of all allergy drugs. Loratadine. Cetirizine. Fexofenadine. These are newer. They are less likely to clog things up. Thanki suggests switching if you can.
Calcium Supplements
Good for bones. Terrible for bowel movements.
Especially calcium carbonate. Thanki says it decreases smooth muscle contractions.
It binds to fatty acids and bile. Less lubrication inside the gut.
Your body also secretes less fluid into the bowel. The result is hard dry stool.
Ignoring the Urgue
We get busy. Meetings. Traffic. We hold it in.
Don’t do it constantly.
Dr. McAbee says ignoring the urge leads to “maladaptive learning.” Your rectum changes its sensation threshold. You stop feeling the signal to go.
If stool sits in the colon too long the colon reabsorbs the water from it.
Polman explains this makes the waste dry. And hard. Which creates constipation. A vicious loop.
Iron Supplements
Like calcium. Iron interferes with normal gut function.
It irritates the gut mucosa. The moist lining gets angry.
Motility slows down. Polman says oral iron creates “hard bulky dry stool.” It is objectively unpleasant.
Anxiety And Depression
Your mood affects your bowels.
The gut-brain axis works both ways. Prevalence of constipation is twice as high in people with depression or anxiety compared to those without.
Polman points out the fight-or-flight response keeps muscles tight. Less movement. Plus meds for anxiety often list constipation as a side effect.
Getting It Moving Again
Start simple.
Drink water. Look for pale yellow urine. That is a sign you are hydrated.
Fiber needs vary but adults need 25 to 30 grams daily. Polman recommends kiwis. They actually help.
Sleep at least seven hours a night. Exercise 150 minutes a week.
If that fails check your meds. Are they making you constipated?
“If stool consistency remains problematic”
Dr. McAbee suggests osmotic laxatives. Polyethylene glycol or milk of magnesium. If those don’t work you can use stimulant laxatives like bisacodyl. Or glycerin suppositories.
It should not be complicated but often is.
If the problem persists see a gastroenterologist. Especially if there is bleeding. Or unexplained weight loss.
Occasional backup is life. Constant backup is a problem that needs attention. But we tend to sit it out for far too long.
