Constipation: Symptoms, Causes & Relief

Constipation is one of the most common digestive complaints, and for most people it's temporary and manageable at home. It generally means bowel movements that are infrequent, hard, or difficult to pass — and it's defined more by a change from your normal than by hitting a specific number.

Quick answer: Constipation usually responds to more fiber, more fluid, and more movement. See a doctor if it lasts more than three weeks, comes with blood or severe pain, or alternates with diarrhea.

Symptoms of constipation

  • Fewer than three bowel movements a week
  • Hard, dry, or lumpy stool (Bristol types 1–2)
  • Straining or pain when passing stool
  • A feeling that you haven't fully emptied
  • Bloating or abdominal discomfort

Common causes

  • Too little fiber in the diet
  • Not enough fluid
  • Low physical activity
  • Ignoring or delaying the urge to go
  • Medications — iron, opioid painkillers, and some antacids
  • Routine changes — travel, stress, schedule shifts
  • Some conditions — an underactive thyroid, pregnancy, IBS

How to relieve constipation

  • Build up fiber gradually — fruits, vegetables, whole grains, legumes (increasing too fast can cause gas).
  • Drink more fluid — fiber needs water to work.
  • Move more — even a daily walk helps stimulate the bowel.
  • Don't delay the urge — go when you feel it.
  • Set a routine — try a consistent time, such as after breakfast.

Over-the-counter options like fiber supplements or gentle laxatives can help short-term, but it's worth asking a pharmacist or doctor before relying on laxatives regularly.

When to see a doctor

  • Constipation lasting more than three weeks despite home measures
  • Blood in the stool, or black, tarry stool
  • Severe abdominal pain, vomiting, or bloating
  • Constipation alternating with diarrhea
  • Unexplained weight loss

Frequently asked questions

What is the fastest way to relieve constipation?

Increasing fluid, gentle movement, and fiber helps over a day or two. Short-term, a pharmacist can advise on fiber supplements or a gentle laxative. Persistent constipation should be assessed by a doctor.

How many days without pooping is constipation?

Fewer than three bowel movements a week, or a clear drop from your usual pattern with hard, hard-to-pass stool, is generally considered constipation.

Can constipation be serious?

Usually it's not. But constipation lasting over three weeks, or with blood, severe pain, vomiting, weight loss, or alternating diarrhea, should be evaluated by a doctor.

What foods help with constipation?

Fiber-rich foods — fruits, vegetables, whole grains, and legumes — along with enough fluid. Increase fiber gradually to avoid gas and bloating.
