  • Common symptoms include fewer than three bowel movements per week, straining, hard or lumpy stools, bloating, gas, abdominal discomfort, and a feeling that stool is stuck.
  • Common causes include a low-fiber diet, dehydration, lack of physical activity, certain medications, pregnancy, IBS, thyroid disorders, diabetes, and other medical conditions.
  • Many cases improve with more fiber, adequate fluids, regular physical activity, and healthier bowel habits.
  • Fiber supplements, stool softeners, laxatives, and prescription medications may be used when lifestyle changes are not enough.
  • Severe abdominal pain, persistent vomiting, a swollen abdomen, or inability to pass stool or gas with severe pain requires urgent medical evaluation.

What Is Constipation?

Constipation is a common digestive condition in which bowel movements become infrequent, difficult to pass, or both. Although bowel habits vary from person to person, constipation is generally defined as having fewer than three bowel movements per week, passing hard or dry stools, or feeling that you are unable to completely empty your bowels.

Constipation may be acute (short-term) or chronic (lasting several weeks or longer). Most cases are temporary and improve with dietary changes, increased fluid intake, physical activity, and other lifestyle modifications. However, persistent constipation may be a sign of an underlying medical condition and should be evaluated by a healthcare provider.

Common causes include a low-fiber diet, dehydration, lack of physical activity, certain medications, pregnancy, irritable bowel syndrome (IBS), thyroid disorders, neurological conditions, and bowel disorders.

Frequently Asked Questions

How often should I have a bowel movement?

Normal bowel habits vary widely. Some people have bowel movements three times a day, while others have them three times a week. Both may be normal if stools are passed comfortably.

Can constipation cause abdominal pain?

Yes. Constipation commonly causes abdominal pain, bloating, cramping, and discomfort.

Can fiber make constipation worse?

Increasing fiber too quickly without drinking enough water may worsen constipation. Fiber should be increased gradually while maintaining adequate hydration.

When should I see a healthcare provider?

Seek medical evaluation if constipation lasts longer than three weeks, is associated with severe pain, unexplained weight loss, blood in the stool, or persistent vomiting.

Can constipation lead to hemorrhoids?

Yes. Repeated straining during bowel movements increases the risk of hemorrhoids and anal fissures.

Questions To Ask Your Provider

Consider asking your healthcare provider:

  • What is causing my constipation?
  • Could one of my medications be contributing?
  • Should I increase my fiber intake?
  • Do I need additional testing?
  • Which laxative is safest for me?
  • When should I seek emergency medical care?
  • Should I see a gastroenterologist?

Specialist Referrals

Most cases of constipation are treated by a primary care provider. Depending on your symptoms or diagnosis, your provider may recommend seeing a specialist.

You may be referred to:

  • Primary Care Provider: Coordinates diagnosis, treatment, and follow-up care.
  • Gastroenterologist: Evaluates chronic constipation, inflammatory bowel disease, colorectal disorders, and other digestive conditions.
