Bowel or Bladder
Some MS lesions can block or delay nerve messages that control the bladder. This can cause bladder problems. Bladder problems, which occur in at least 80% of people with MS, can usually be managed.
Bladder symptoms may include:
- Frequency or urgency of urination
- Hesitancy in starting urination
- Frequent nighttime urination (known as nocturia)
- Incontinence (the inability to hold in urine)
The most common bladder problem is called "spastic" bladder. That's when the bladder is unable to hold the normal amount of urine or does not empty properly. This can leave urine in the bladder and possibly lead to infection.
Constipation is another concern for people with MS. Constipation may be caused by too little fluid intake. It also may be caused by your intestinal tract slowing down. If you have become less active, you may become constipated. Certain medications used to control bladder symptoms may also cause constipation.
Dealing with bladder/bowel problems
One way to treat a bladder problem is to change your fluid intake (eg, limit fluid intake a few hours before bedtime, cut out caffeine). Also, your health care provider can prescribe medicine. It is important to get examined and treated early, so that you can avoid any complications, like bladder infections.
Here are some tips to help you deal with bowel and bladder problems:
- Drink at least 6 to 8 glasses of fluid (preferably water) daily.
- Include plenty of fiber in your diet. Fresh fruits and vegetables, whole grain breads, and cereals all contain fiber.
- Use medicines such as stool softeners as recommended by your health care provider.
- Establish a regular time and schedule for emptying the bowels.
- Wait no more than 2 to 3 days between bowel movements.
- Enemas, suppositories, and laxatives may be used to help a bowel movement—talk with your health care provider before using any of these options.
Your health care provider can help you establish an effective bowel management program. Occasionally, it may be necessary to consult a gastroenterologist. He or she is a health care provider that specializes in treating the stomach and bowel.
