General Questions

What is constipation?

A division of the National Institutes of Health defines constipation as having a bowel movement fewer than three times a week. Stools are usually hard, dry, small in size and difficult to eliminate. People with constipation usually either have very large hard stools or hard pellet-like stools. Bowel movements are infrequent and often painful.

Feces (Fecal)

Waste product stored in the rectum and excreted through the anus.

What causes constipation?

Lots of things can cause constipation. Common causes include: not getting enough fiber, fluids or insufficient exercise. However, constipation can also result from a more serious medical condition.

How do I help prevent constipation?

There are several things you can do to help prevent constipation. Make sure you eat a well-balanced diet with plenty of fiber. You also need to drink lots of fluids and get plenty of exercise.

How much fiber do you need per day?

The Institute of Medicine of the National Academies recommends 38 grams of fiber for adult men and 25 grams of fiber for adult women.

What are the different categories of laxatives?

Laxatives are grouped into the following categories:

  • Bulk-forming: An agent that increases bulk volume and water content of the stool, which then promotes a bowel movement.
  • Carbon dioxide-releasing: A suppository agent that contains ingredients that release carbon dioxide, which then induces gentle pressure in the rectum and promotes a bowel movement.
  • Hyperosmotic: An agent that attracts water into the stool and promotes a bowel movement. For example, Fleet Liquid Glycerin and Glycerin Suppositories.
  • Lubricant: An agent that lubricates the contents of the intestinal tract, which coats the stool mass to keep moisture in, thereby helping to soften the stool mass and make it easier to pass. For example, Fleet Mineral Oil Enema.
  • Saline: An agent that increases water in the intestine, which promotes a bowel movement. For example, Fleet Enema.
  • Stimulant : An agent that promotes a bowel movement by directly acting on the intestine. For example, Fleet Bisacodyl Enema and Fleet Bisacodyl Tablets.
  • Stool softener: An agent that penetrates and softens stool, which promotes easier passage of stool. For example, Fleet Sof-Lax Stool Softener.

Which laxative is right for you?

Laxatives are chosen by individual preference or at the recommendation of your physician.

For constipation, why choose enemas vs. oral vs. suppositories?

Rectal laxatives provide immediate relief and are a good alternative for someone who cannot take oral medication. Some enemas can work in 5 minutes or less, while suppositories work within an hour. Oral laxatives work over a longer period of time and can be used when immediate relief is not necessary. Oral laxatives’ time of relief varies, but many work overnight.

Are all Fleet products doctor-recommended?

Are Fleet laxatives gluten-free?
