Getting the Facts on Constipation
ROCHESTER, Minn. -- While sometimes the solution is simple, for example, short-term use of a laxative or eating more fiber, relieving constipation sometimes can be more difficult. For many older adults, constipation is a chronic problem that requires an individualized treatment plan.
The August issue of Mayo Clinic Health Letter sorts myth from fact on a health concern that affects virtually everyone at some point -- constipation.
Myth: An absence of daily bowel movements indicates constipation.
Fact:
Constipation is most accurately defined as the infrequent or difficult
passing of stool. Normal bowel movement frequency in adults can range
from three times a day to three times a week.
Myth: Constipation causes the body to absorb toxins from stools.
Fact:
Not true. This belief causes some people to unnecessarily take laxatives
when a daily bowel movement doesn’t occur. Others try colon cleansing to
remove supposed toxins. These practices aren’t helpful and may be
harmful.
Myth: An unhealthy diet causes constipation.
Fact: A low-fiber diet
may contribute to constipation, but chronic constipation often involves
other factors. Constipation can be a complication of another disease or
condition, or a side effect from a drug or supplement. In women,
constipation can be caused by pelvic floor dysfunction -- a lack of
coordination of the complex muscular actions that allow bowel movements.
This condition is most common in those who have had surgery of the
rectum or anus or who have given birth vaginally.
Myth: Laxatives shouldn’t be used long term.
Fact: New studies
indicate that long-term laxative use prescribed by a physician can be
safe and effective for some forms of constipation. Because side effects
may occur, laxatives should be taken under a physician’s supervision.
Myth: Laxatives and surgery are the only two ways to treat chronic
constipation.
Fact: There are many treatment options and many of
them depend on a patient’s circumstances. Laxative medications are an
option, as well as treating any underlying diseases or adjusting
medications that could be contributing to the condition. Surgery is used
rarely and as a last resort.
In recent years, pelvic floor rehabilitation (biofeedback therapy) has worked well for women with constipation due to pelvic floor dysfunction. Biofeedback involves using sensors to detect contractions and relaxation of the muscles used for bowel movements. Working with a therapist, patients relearn how to control and coordinate the necessary muscles for a bowel movement.
When constipation involves new symptoms, is associated with bleeding, significant abdominal pain or nausea, the advice is to seek prompt medical care.
Stress Management, Diet Changes Improve Irritable Bowel Syndrome Symptoms
ROCHESTER, Minn. -- When persistent cramping, abdominal pain, bloating, gas, diarrhea and constipation are causing distress and frequent bathroom trips, the next stop should be a visit to the doctor. These symptoms, commonly caused by irritable bowel syndrome (IBS), often can be minimized with diet and lifestyle changes.
In the August issue, Mayo Clinic Health Letter outlines what occurs in IBS and how this usually chronic condition is managed.
The walls of the intestines are lined with layers of muscles that contract and relax in a coordinated rhythm as they move food from the stomach through the intestinal tract and to the rectum. With IBS, the contractions may be stronger and last longer than normal, causing bloating and diarrhea. Sometimes, the opposite occurs. Slow food passage causes hard, dry stools.
What causes IBS is not clear, so treatment typically focuses on avoiding triggers and on symptom relief. Mild signs and symptoms may be controlled by managing stress; many people’s symptoms are aggravated by stress symptoms. Diet changes also are helpful. Chocolate, milk and alcohol might cause constipation or diarrhea. Carbonated beverages and some fruits or vegetables may lead to bloating or discomfort.
When symptoms are moderate to severe, a doctor may recommend fiber supplements or anti-diarrheal medications. Some people with diarrhea may benefit from anticholinergic medications to relieve painful bowel spasms. However, the same medication can worsen symptoms for people with constipation. Low-dose antidepressant medications may be appropriate, because they inhibit the activity of neurons that control intestinal muscles.
Seeking a doctor’s care is important when experiencing chronic bowel symptoms. Because there are no physical signs to definitively diagnose IBS, diagnosis is often a process of elimination. And cramping, diarrhea, constipation and other bowel symptoms also can indicate more serious conditions such as ulcerative colitis or Crohn’s disease, forms of inflammatory bowel disease, or colon cancer.
Staying Intimate Later in Life
ROCHESTER, Minn. -- Many older adults -- ages 65 to 85 -- remain sexually active and consider sexuality an important part of their lives. But with age, sexuality also can be challenging. The August issue of Mayo Clinic Health Letter looks at some of the challenges and solutions to cultivating sexual desire later in life.
For men and women, medical conditions that affect general health and well-being can interfere with sexuality. Diabetes, high blood pressure and high cholesterol can affect the cardiovascular system, and adequate blood circulation figures strongly in arousal during sexual activities. Conditions affecting joint health, such as osteoarthritis and rheumatoid arthritis, may impair movement or cause pain. A decrease in sexual drive (libido) is common in older adults.
For women, changes in body shape that occur naturally can affect feelings of desirability. Decreased estrogen levels result in thinning of vaginal tissues and less natural vaginal lubrication. These changes may reduce sexual desire because of pain or discomfort during sexual stimulation. With age, orgasms typically become more muted.
For men, testosterone levels gradually decrease over time, meaning erections may take longer to achieve and may not be as firm. Erectile dysfunction becomes more common as men age.
But the desire for emotional intimacy defies age; the focus on a physical relationship can shift increasingly to an emotional one. This change tends to bring older adults together for satisfying sexual intimacy even if arousal and orgasm aren’t the same as they once were. While the clock can’t be turned back, Mayo Clinic Health Letter describes ways to enhance sexual experiences later in life:
Communication: Partners need to talk openly about any physical difficulties as well as changes in sexual function or sexual enjoyment.
Women’s options: Nonprescription products can help with vaginal dryness due to menopause. Options include a nonprescription, water-based moisturizer (Replens) or non-glycerin lubricants such as System Jo H20 or Slippery Stuff. Vaginal estrogen, available by prescription, is another option.
Men’s options: Drugs such as sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra) are available to treat erectile dysfunction. However, they don’t affect libido.
Other medications: Antidepressants, opiate-type drugs used for pain relief, and high blood pressure medications may affect sexual function negatively. A doctor may be able to offer other treatment options.
Exercise: Regular exercise can improve energy levels and also helps stimulate blood flow to the genitals.
Counseling: A trained therapist can offer education, suggestions, and tailored interventions to help address sexual concerns.
