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.
