Constipation can be caused by a variety of factors including travel, or changes in diet or fluid intake. Disease, disability, hospital stays, and medicine — including prescription and over-the-counter medications — can all cause constipation as well.

What Causes Constipation?

Inadequate Diet

Often constipation is simply the result of "not enough": not drinking enough fluids, not including enough fiber in our diet. Other times, constipation is the result of just "too much": too much intake of unhealthy or processed foods.


Many people are unaware that constipation is also associated with many prescription and over-the-counter drugs (View list now.).

Ignoring Bowel Movements

If you ignore the urge to have a bowel movement over time, you may stop feeling the need to have one. You may delay having a bowel movement because you do not want to use toilets outside of your home, do not have access to a toilet, or may feel you are too busy. This habit can lead to constipation.

Who Gets Constipated?

Constipation can affect anyone, at any age. About 4 million people say they have issues with constipation. Constipation affects almost everyone at some point in their lives.

So if you're an occasional sufferer you're certainly not alone. And the good news is, no matter what your age or situation, you can do something to help avoid and ease your constipation.

New Mothers

Following childbirth, many women experience constipation due to a slowdown of the digestive system and a temporary reduction of muscle tone in the abdomen. In addition, discomfort from surgical incisions may require pain medicines, some of which can cause constipation.


No matter what your age or physical condition, business or vacation travel can disrupt your regular eating, sleeping, and normal bowel routines. The search for a toilet in an unfamiliar place can cause you to postpone the urge to go to the bathroom. When packing for a trip, be sure to take along a laxative just in case you develop a temporary problem with constipation.

Sedentary Lifestyle

Along with all the other benefits of exercise, add one more: it can help you avoid constipation. Sedentary people are simply more prone to problems with constipation than the physically active. Since exercise is so important, ask your doctor to recommend a fitness routine that suits your needs.

Patients Taking Medications

Constipation may be associated with many prescription and over-the-counter medications. For more information, refer to "What medications may cause constipation?"

Patients Recovering from Surgery

New medications or inadequate physical activity are all factors that contribute to constipation after surgery. Your physician may recommend a laxative if you are recovering from surgery and having problems with constipation.

Medications Associated with Constipation

Many prescription and many commonly used over-the-counter medications can disrupt your digestive system. Medications associated with constipation include antacids, antidepressants, opioid containing cough medicines, cold medicines, anti-parkinsons medications, and pain relievers. Some medications used to treat anemia, high blood pressure, high cholesterol and various cardiovascular conditions, can also be associated with constipation.

Sometimes constipation is just a short-term problem that occurs as your body adjusts to a new medication. In other instances constipation is a side effect that usually will not lessen over time.

If you are taking prescription pain medication, you may, with your doctor's recommendation, need to treat your constipation for as long as you are taking the medication. Doctors and pharmacists may recommend a laxative plus stool-softener — such as dual-action Senokot-S Tablets — to treat both the bowel immobilizing and stool-hardening effects of some medications.

Do not use laxative products for longer than one week unless directed by a doctor.
