It is normal to have between a few bowel movements per day to two or three bowel movements per week. Because of the serious problems that can occur from constipation in the patient with chronic pain, the goal should be one soft bowel movement every one to two days without cramping or straining. Inactivity and lack of exercise can slow down the bowel. Exercise stimulates bowel contractions. Because of pain, many chronic pain patients are not active.
Medications frequently cause constipation.
Constipation can be painful. In the extreme, it can lead to complete blockage and serious medical problems. If you take opioid pain medicines on a regular basis, you should be taking medicines on a regular basis. Again, the goal should be one soft bowel movement every one to two days without cramping or requiring straining. Generic drugs may be cheaper and work just as well.
