Many events or conditions can damage nerves that control bladder function, including diabetes and other diseases, injuries, and infections. More than half of men and women with diabetes have bladder dysfunction because of damage to nerves that control bladder function. Bladder dysfunction can have a profound effect on a person’s quality of life. Common bladder problems in men and women with diabetes include the following:
Treatment may include:
Treatment of bladder problems due to nerve damage depends on the specific problem. If the main problem is urine retention, treatment may involve medication to promote better bladder emptying and a practice called timed voiding-urinating on a schedule-to promote more efficient urination. Sometimes people need to periodically insert a thin tube called a catheter through the urethra into the bladder to drain the urine. Learning how to tell when the bladder is full and how to massage the lower abdomen to fully empty the bladder can help as well. If urinary leakage is the main problem, medications, strengthening muscles with Kegel exercises, or surgery can help. Treatment for the urinary urgency and frequency of overactive bladder may involve medications, timed voiding, Kegel exercises, and surgery in some cases.
Diabetes is the most common cause of kidney failure, even when diabetes is controlled, the disease can lead to chronic kidney disease (CKD) and kidney failure. Most people with diabetes do not develop CKD that is severe enough to progress to kidney failure. Diabetic kidney disease takes many years to develop. In some people, the filtering function of the kidneys is actually higher than normal in the first few years of their diabetes.
Over several years, people who are developing kidney disease will have small amounts of the blood protein albumin begin to leak into their urine. This first stage of CKD is called micro-albuminuria. The kidney’s filtration function usually remains normal during this period.
As the disease progresses, more albumin leaks into the urine. This stage may be called macro-albuminuria or proteinuria. As the amount of albumin in the urine increases, the kidneys’ filtering function usually begins to drop. The body retains various wastes as filtration falls. As kidney damage develops, blood pressure often rises as well.
Treatment for Diabetes Related CKD:
There are currently two treatments for CKD related to diabetes; dialysis or transplant. When people with diabetes experience kidney failure, they must undergo either dialysis or a kidney transplant. As recently as the 1970s, medical experts commonly excluded people with diabetes from dialysis and transplantation, in part because the experts felt damage caused by diabetes would offset benefits of the treatments. Today, because of better control of diabetes and improved rates of survival following treatment, doctors do not hesitate to offer dialysis and kidney transplantation to people with diabetes.
Currently, the survival of kidneys transplanted into people with diabetes is about the same as the survival of transplants in people without diabetes. Dialysis for people with diabetes also works well in the short run. Even so, people with diabetes who receive transplants or dialysis experience higher morbidity and mortality because of coexisting complications of diabetes-such as damage to the heart, eyes, and nerves.
Both men and women with diabetes can develop sexual problems because of damage to nerves and small blood vessels. When a person wants to lift an arm or take a step, the brain sends nerve signals to the appropriate muscles. Nerve signals also control internal organs like the heart and bladder, but people do not have the same kind of conscious control over them as they do over their arms and legs. The nerves that control internal organs are called autonomic nerves, which signal the body to digest food and circulate blood without a person having to think about it. The body’s response to sexual stimuli is also involuntary, governed by autonomic nerve signals that increase blood flow to the genitals and cause smooth muscle tissue to relax. Damage to these autonomic nerves can hinder normal function. Reduced blood flow resulting from damage to blood vessels can also contribute to sexual dysfunction.
Sexual problems affecting men:
Erectile dysfunction is a consistent inability to have a penile erection firm enough for sexual intercourse. The condition includes the total inability to have an erection and the inability to sustain an erection.
Estimates of the prevalence of erectile dysfunction in men with diabetes vary widely, ranging from 20 to 75 percent. Men who have diabetes are two to three times more likely to have erectile dysfunction than men who do not have diabetes. Among men with erectile dysfunction, those with diabetes may experience the problem as much as 10 to 15 years earlier than men without diabetes. Research suggests that erectile dysfunction may be an early marker of diabetes, particularly in men ages 45 and younger.
In addition to diabetes, other major causes of erectile dysfunction include high blood pressure, kidney disease, alcohol abuse, and blood vessel disease. Erectile dysfunction may also occur because of the side effects of medications, psychological factors, smoking, and hormonal deficiencies.
Men who experience erectile dysfunction should consider talking with a health care provider. The health care provider may ask about the patient’s medical history, the type and frequency of sexual problems, medications, smoking and drinking habits, and other health conditions. A physical exam and laboratory tests may help pinpoint causes of sexual problems. The health care provider will check blood glucose control and hormone levels and may ask the patient to do a test at home that checks for erections that occur during sleep. The health care provider may also ask whether the patient is depressed or has recently experienced upsetting changes in his life.
Treatments for erectile dysfunction caused by nerve damage, also called neuropathy, vary widely and range from oral pills, a vacuum pump, pellets placed in the urethra, and shots directly into the penis, to surgery. All of these methods have advantages and disadvantages. Psychological counseling to reduce anxiety or address other issues may be necessary. Surgery to implant a device to aid in erection or to repair arteries is usually used as a treatment after all others fail.
Retrograde ejaculation is a condition in which part or all of a man’s semen goes into the bladder instead of out the tip of the penis during ejaculation. Retrograde ejaculation occurs when internal muscles, called sphincters, do not function normally. A sphincter automatically opens or closes a passage in the body. With retrograde ejaculation, semen enters the bladder, mixes with urine, and leaves the body during urination without harming the bladder. A man experiencing retrograde ejaculation may notice that little semen is discharged during ejaculation or may become aware of the condition if fertility problems arise. Analysis of a urine sample after ejaculation will reveal the presence of semen.
Poor blood glucose control and the resulting nerve damage can cause retrograde ejaculation. Other causes include prostate surgery and some medications.
Sexual problems affecting women:
Many women with diabetes experience sexual problems. Although research about sexual problems in women with diabetes is limited, one study found 27 percent of women with type 1 diabetes experienced sexual dysfunction. Another study found 18 percent of women with type 1 diabetes and 42 percent of women with type 2 diabetes experienced sexual dysfunction.
Sexual problems may include:
Decreased or absent sexual response can include the inability to become or remain aroused, reduced or no sensation in the genital area, and the constant or occasional inability to reach orgasm.
Causes of sexual problems in women with diabetes include nerve damage, reduced blood flow to genital and vaginal tissues, and hormonal changes. Other possible causes include some medications, alcohol abuse, smoking, psychological problems such as anxiety or depression, gynecologic infections, other diseases, and conditions relating to pregnancy or menopause.
Women who experience sexual problems or notice a change in sexual response should consider talking with a health care provider. The health care provider will ask about the patient’s medical history, any gynecologic conditions or infections, the type and frequency of sexual problems, medications, smoking and drinking habits, and other health conditions. The health care provider may ask whether the patient might be pregnant or has reached menopause and whether she is depressed or has recently experienced upsetting changes in her life. A physical exam and laboratory tests may also help pinpoint causes of sexual problems. The health care provider will also talk with the patient about blood glucose control.
Prescription or over-the-counter vaginal lubricants may be useful for women experiencing vaginal dryness. Techniques to treat decreased sexual response include changes in position and stimulation during sexual relations. Psychological counseling may be helpful. Kegel exercises that help strengthen the pelvic muscles may improve sexual response. Studies of drug treatments are under way.
