Constipation is a common condition characterized by infrequent bowel movements, difficulty passing stools, or a feeling of incomplete bowel movements. It is usually caused by a lack of fiber, fluids, or physical activity in one's diet, as well as other factors such as certain medications, health conditions, or lifestyle habits.

Symptoms of constipation may include:

• Fewer than three bowel movements per week
• Straining during bowel movements
• Hard, lumpy or small stools
• A feeling of incomplete bowel movements
• Abdominal pain or discomfort
• Bloating or gas

Treatment for constipation usually involves lifestyle changes such as increasing fiber and fluid intake, increasing physical activity, and establishing regular bowel habits. Over-the-counter laxatives, stool softeners, and enemas may also be used to help relieve constipation. In cases where constipation is caused by an underlying health condition, such as hypothyroidism or irritable bowel syndrome, treating the underlying condition may help alleviate constipation.

In some cases, constipation can lead to complications such as hemorrhoids, anal fissures, or fecal impaction, so it is important to seek medical attention if symptoms persist or worsen. Additionally, it is important to maintain a healthy diet and lifestyle habits to prevent constipation and promote regular bowel movements.

Constipation most commonly occurs when waste or stool moves too slowly through the digestive tract or cannot be eliminated effectively from the rectum, which may cause the stool to become hard and dry. Chronic constipation has many possible causes.

The following can help you avoid developing chronic constipation.

• Include plenty of high-fiber foods in your diet, including beans, vegetables, fruits, whole grain cereals and bran.
• Eat fewer foods with low amounts of fiber such as processed foods, and dairy and meat products.
• Drink plenty of fluids.
• Stay as active as possible and try to get regular exercise.
• Try to manage stress.
• Don't ignore the urge to pass stool.
• Try to create a regular schedule for bowel movements, especially after a meal.
• Make sure children who begin to eat solid foods get plenty of fiber in their diets.

Treatment for chronic constipation usually begins with diet and lifestyle changes meant to increase the speed at which stool moves through your intestines. If those changes don't help, your doctor may recommend medications or surgery.

Diet and lifestyle changes

Your doctor may recommend the following changes to relieve your constipation:

• Increase your fiber intake. Adding fiber to your diet increases the weight of your stool and speeds its passage through your intestines. Slowly begin to eat more fresh fruits and vegetables each day. Choose whole-grain breads and cereals.
• Your doctor may recommend a specific number of grams of fiber to consume each day. In general, aim for 14 grams of fiber for every 1,000 calories in your daily diet.
• A sudden increase in the amount of fiber you eat can cause bloating and gas, so start slowly and work your way up to your goal over a few weeks.
• Exercise most days of the week. Physical activity increases muscle activity in your intestines. Try to fit in exercise most days of the week. If you do not already exercise, talk to your doctor about whether you are healthy enough to start an exercise program.
• Don't ignore the urge to have a bowel movement. Take your time in the bathroom, allowing yourself enough time to have a bowel movement without distractions and without feeling rushed.

Laxatives

Several types of laxatives exist. Each works somewhat differently to make it easier to have a bowel movement. The following are available over-the-counter:

• Fiber supplements. Fiber supplements add bulk to your stool. Bulky stools are softer and easier to pass. Fiber supplements include psyllium (Metamucil, Konsyl, others), calcium polycarbophil (FiberCon, Equalactin, others) and methylcellulose (Citrucel).
• Stimulants. Stimulants including bisacodyl (Correctol, Dulcolax, others) and sennosides (Senokot, Ex-Lax, Perdiem) cause your intestines to contract.
• Osmotics. Osmotic laxatives help stool move through the colon by increasing secretion of fluid from the intestines and helping to stimulate bowel movements. Examples include oral magnesium hydroxide (Phillips' Milk of Magnesia, Dulcolax Milk of Magnesia, others), magnesium citrate, lactulose (Cholac, Constilac, others), polyethylene glycol (Miralax, Glycolax).
• Lubricants. Lubricants such as mineral oil enable stool to move through your colon more easily.
• Stool softeners. Stool softeners such as docusate sodium (Colace) and docusate calcium (Surfak) moisten the stool by drawing water from the intestines.
• Enemas and suppositories. Tap water enemas with or without soapsuds can be useful to soften stool and produce a bowel movement. Glycerin or bisacodyl suppositories also aid in moving stool out of the body by providing lubrication and stimulation.

Other medications

If over-the-counter medications don't help your chronic constipation, your doctor may recommend a prescription medication, especially if you have irritable bowel syndrome.

• Medications that draw water into your intestines. A number of prescription medications are available to treat chronic constipation. Lubiprostone (Amitiza), linaclotide (Linzess) and plecanatide (Trulance) work by drawing water into your intestines and speeding up the movement of stool.
• Serotonin 5-hydroxytryptamine 4 receptors. Prucalopride (Motegrity) helps move stool through the colon.
• Peripherally acting mu-opioid receptor antagonists (PAMORAs). If constipation is caused by opioid pain medications, PAMORAs such as naloxegol (Movantik) and methylnaltrexone (Relistor) reverse the effect of opioids on the intestine to keep the bowel moving.

Training your pelvic muscles

Biofeedback training involves working with a therapist who uses devices to help you learn to relax and tighten the muscles in your pelvis. Relaxing your pelvic floor muscles at the right time during defecation can help you pass stool more easily.

During a biofeedback session, a special tube (catheter) to measure muscle tension is inserted into your rectum. The therapist guides you through exercises to alternately relax and tighten your pelvic muscles. A machine will gauge your muscle tension and use sounds or lights to help you understand when you've relaxed your muscles.

Surgery

Surgery may be an option if you have tried other treatments and your chronic constipation is caused by a blockage, rectocele or stricture.

For people who have tried other treatments without success and who have abnormally slow movement of stool through the colon, surgical removal of part of the colon may be an option. Surgery to remove the entire colon is rarely necessary.
