What is constipation?
Constipation is when your stools are painful or they do not happen often enough. It is the most common GI (gastrointestinal) problem.
You may have constipation if:
You have bowel movements less than 3 times a week
Your stool is hard, dry, and in small pieces
Normal bowel movements vary depending on the person. They may happen as often as 3 times a day. Or they may happen just 3 times a week.
What causes constipation?
Your stool gets hard and dry when your colon (large intestine) absorbs too much water.
In most cases, as food moves through your colon, the colon absorbs water while it makes stool. Muscle movements (contractions) push the stool toward your rectum. When the stool gets to the rectum, most of the water has been soaked up. The stool is now solid.
If you have constipation, your colon's muscle movements are too slow. This makes the stool move through your colon too slowly. The colon absorbs too much water. The stool gets very hard and dry.
Some of the most common diet and lifestyle causes of constipation are:
Not getting enough exercise
Not drinking enough liquids
Not eating enough fiber
Not moving your bowels when you feel the urge to
Changes in your lifestyle, such as travel, pregnancy, and old age
Other causes of constipation include:
A problem with how your stomach and bowels work (such as irritable bowel syndrome)
Your intestine does not work well
Taking too many medicines that help to loosen your bowels (laxatives)
Metabolic problems such as thyroid disease
What are the symptoms of constipation?
Each person’s symptoms may vary. Symptoms of constipation may include:
Difficult and painful bowel movements
Less than 3 bowel movements a week
Not having much energy
Belly (abdominal) pain
Ineffective straining to move your bowels
The symptoms of constipation can look like other health problems. Always talk with your healthcare provider to be sure.
How is constipation diagnosed?
Most people have constipation at one time or another. To see if you have constipation, your healthcare provider will do several tests. These tests will depend on how long you have had symptoms and how serious your case is.
First your healthcare provider will look at:
If you have any blood in your stool
Any changes in your bowel habits
Your healthcare provider will likely:
Ask about your past health. You will be asked to give details about your constipation,, such as how long you have had symptoms and how often you have bowel movements.
Give you a physical exam. Your healthcare provider will do a full physical exam.
Give you a digital rectal exam. This exam helps tell if the area is soft, blocked, or bloody. It can also check how much and what kind of stool you have. Your healthcare provider will also see if your rectum is bigger than normal.
Your healthcare provider may also do other tests such as:
Abdominal X-ray. This X-ray test can show the fullness of the bowels.
Blood work. Blood is taken for testing.
Lower GI series (also called barium enema). This is an X-ray exam of your rectum, the large intestine, and the lower part of your small intestine. You will be given a fluid called barium. It coats the organs, so that they can be seen on an X-ray. An X-ray of your belly will show if you have any narrowed areas (strictures), blockages, or other problems.
Colonoscopy.This test looks at the full length of your large intestine. It can help check for any abnormal growths, tissue that is red or swollen, sores (ulcers), or bleeding.
Sigmoidoscopy.This test lets your healthcare provider check the inside of part of your large intestine. It helps to tell what is causing constipation.
Colorectal transit study. This test shows how long it takes for food to move through your colon. You will be asked to swallow pills (capsules) filled with small markers that can be seen on an X-ray. The X-rays will show how the capsules moved through your colon.
Anus and rectum (anorectal) function tests. These tests can tell if you are constipated because your anus or rectum is not working well.
How is constipation treated?
Your healthcare provider will come up with a care plan for you based on:
Your age, overall health, and past health
How serious your case is
How well you handle certain medicines, treatments, or therapies
If your condition is expected to get worse
Your opinion and what you want to do
In most cases, diet and lifestyle changes can help reduce constipation symptoms. They can also stop it from happening. These changes may include:
Drinking more water and juice.
Getting regular exercise.
Giving yourself time to have a bowel movement each day.
Eating more fiber.
Stopping or changing medicine.
Doing biofeedback (part of a special physical therapy program)
Whole-wheat bread, granola bread, wheat bran muffins, grain bars, waffles, popcorn
100% whole-grain cereals, oatmeal, granola, and oat bran
100% bran cereals
Beets, broccoli, Brussels sprouts, cabbage, carrots, corn, green beans, green peas, acorn and butternut squash, spinach, potato with skin, avocado
Apples with peel, dates, papayas, mangoes, nectarines, oranges, pears, kiwis, strawberries, applesauce, raspberries, blackberries, raisins
Cooked prunes, dried figs
Peanut butter, nuts
Baked beans, black-eyed peas, garbanzo beans, lima beans, pinto beans, kidney beans, chili with beans, trail mix
What are possible complications of constipation?
Constipation can cause other health problems such as:
Hemorrhoids. Red, swollen veins in the rectum. They happen when you need to keep straining to have a bowel movement.
Anal fissures. Tears in the skin around the anus. They happen when hard stool stretches your sphincter muscle. They can cause bleeding in your rectum.
Rectal prolapse. This is when a small amount of your intestinal lining pushes out from your anal opening. It is caused by straining to have a bowel movement.
Fecal impaction. This is when a large lump of hard, dry stool stays stuck in your rectum. The colon’s normal pushing action can’t push out the stool. This is seen mostly in children and older adults.
Can constipation be prevented?
Many of the same lifestyle changes that help treat constipation may also help to stop it from happening:
Have plenty of fiber, water, and liquids each day.
Get regular exercise.
Allow plenty of time for bowel movements. When you feel the urge to have a bowel movement, be sure to do it.
Try to have a bowel movement at the same time each day.
If another health problem makes you more likely to have constipation, take your healthcare provider’s advice for treating that problem.
When should I call my healthcare provider?
Most people have constipation at one time or another. But call your healthcare provider if:
Constipation lasts longer than 3 weeks.
Constipation pain is stopping you from doing your daily activities.
You have symptoms of any of the complications of constipation.
