Problems of the Digestive System
Frequently Asked Questions
Overview Expand All
-
Common digestive problems include the following:
-
Constipation
-
Diarrhea
-
Acid reflux
-
Hemorrhoids
Most common digestive problems are short term and easy to control with lifestyle changes and sometimes medication. If symptoms don’t get better, or if they get worse, talk with your health care professional. In some cases, these problems can be a sign of more serious medical conditions.
-
-
What are examples of common digestive disorders?
Common digestive disorders include the following:
-
Irritable bowel syndrome (IBS)
-
Celiac disease
These disorders affect more women than men. They can last for long periods of time, although symptoms can come and go.
-
Constipation Expand All
-
Constipation involves having fewer than three bowel movements a week. Stools may be firm or hard to pass. Your abdomen may feel swollen or bloated.
-
Common causes of constipation include
-
not eating enough fiber
-
not drinking enough water
-
certain medications
-
changes in routine (such as travel)
During pregnancy, increased levels of hormones can slow down the digestive system and cause constipation.
-
-
Fiber is found in plant foods. It's the part of the plant that your body cannot digest. Fiber passes relatively unchanged through your digestive system. It can help prevent constipation by adding bulk to the stool, making it easier to pass. A fiber-rich diet may also help lower cholesterol levels and help you maintain a healthy weight.
Current guidelines recommend that women eat 25 grams of fiber per day. Most Americans only get about 15 grams per day.
-
Good sources of fiber include fruits, vegetables, beans, whole grains, and bran. Whole grains include steel-cut oatmeal, brown rice, barley, and corn (including popcorn). Bran is the outer covering of grains such as corn and wheat. It is used as a high-fiber ingredient in cereals and other foods.
-
If constipation continues, your health care professional may suggest a laxative. Most of these products are available without a prescription.
-
Different types of laxatives work in different ways:
-
Bulk-forming laxatives absorb water and expand, which increases moisture in the stool and makes it easier to pass (these are thought to be the safest laxatives).
-
Stool softeners add liquid content to the stool to soften it.
-
Stimulants use a chemical to increase bowel activity, which moves the stool through the intestines.
Laxatives, especially stimulants, should be used with caution. You should stop using these products once your bowel movements become regular again. Overuse of stimulants can cause your bowels to depend on them.
-
-
You can help prevent constipation by
-
drinking plenty of water
-
eating at least 25 grams of fiber a day
-
exercising
-
not holding your stool (using the bathroom when you feel the urge to have a bowel movement)
-
Diarrhea Expand All
-
Diarrhea is having three or more loose bowel movements a day. It can also cause cramping.
-
Several things can cause diarrhea:
-
Infection with harmful bacteria or viruses, which can be caused by eating or drinking contaminated food or water
-
Consuming dairy products (if you are lactose intolerant), caffeine, artificial sweeteners, or certain additives
-
Taking medications, especially antibiotics
-
Digestive diseases, such as irritable bowel syndrome (IBS)
-
-
Diarrhea can cause dehydration (loss of fluids from the body). If you have diarrhea, drink plenty of fluids to replace those that are lost.
If diarrhea does not go away in a few hours, drink fluids and liquid foods that contain salt, such as sports drinks or broth. Avoid drinking dairy products, soda, and juices. They may contain lactose, caffeine, or sugar, which may make diarrhea worse.
Over-the-counter anti-diarrheal medications can be helpful. But they should not be taken if you have a high fever or bloody diarrhea, which can be signs of a bacterial infection.
-
If diarrhea lasts more than 2 days, see your health care professional. Also see your health care professional if
-
your stools contain blood or pus
-
you have a fever
-
you have severe abdominal pain
-
you have signs of dehydration (thirst, dry skin, fatigue, dizziness, less frequent urination, or dark-colored urine)
You may need tests to find the cause of your diarrhea so that the right treatment can be given.
-
-
If you use birth control pills, diarrhea or vomiting may decrease their effectiveness. Talk with your health care professional about what to do if you have vomiting or diarrhea that lasts for 48 hours or more after taking a combined birth control pill or that lasts for 3 hours or more after taking a progestin-only pill.
Acid reflux Expand All
-
Acid reflux happens when the muscle in your esophagus that opens and closes when you swallow does not work properly. When this happens, food and digestive fluids, which contain acid, back up into your esophagus. Acid reflux can cause a burning feeling in your chest and throat, which is sometimes called heartburn.
Acid reflux is common and usually is not serious.
-
You may notice acid reflux more often when you drink alcohol or caffeine or eat certain foods, such as citrus fruits, tomatoes, or fried foods. It may become more frequent while lying down. It happens more often during pregnancy as well as in people who are obese or who smoke.
-
Try taking these steps:
-
Raise the head of your bed.
-
Eat small, more frequent meals.
-
Quit smoking.
-
Avoid foods and drinks that make your symptoms worse.
-
Avoid lying on your back right after eating.
-
-
Several over-the-counter medications are available that may help reduce your symptoms. Antacids reduce the acid content in the stomach. Other medications stop the digestive system from making too much acid. Some of these medications are available over the counter.
-
If acid reflux happens more than twice a week, or if you have been taking over-the-counter medications for more than 2 weeks with no relief, you may have a condition called gastroesophageal reflux disease (GERD). Treatment includes lifestyle changes and medication. Surgery can be used to treat GERD in some cases.
GERD that is not treated can lead to complications, including ulcers in the esophagus, narrowing of the esophagus, and a precancerous condition called Barrett's esophagus. If you have GERD, it is important to see your health care professional regularly for treatment and follow-up.
Hemorrhoids Expand All
-
Hemorrhoids can result from several factors:
-
Being overweight
-
Pregnancy
-
Standing or sitting for long periods
-
Straining during physical labor
-
Constipation (straining to have bowel movements)
Adding fiber and fluids to your diet can help prevent hemorrhoids.
-
-
The symptoms of hemorrhoids can be relieved with ice packs to reduce swelling. Sitting in a bath of warm water may relieve symptoms. You may also use a hemorrhoid cream or suppositories. If problems do not go away, contact your health care professional. Surgery may be needed to remove hemorrhoids in some cases.
Irritable Bowel Syndrome Expand All
-
IBS mainly affects women between the ages of 30 and 50. For some people, it is only mildly annoying. For others, it can be serious. Symptoms may include the following:
-
Cramps
-
Gas
-
Bloating
-
Changes in bowel habits—constipation, diarrhea, or both
-
An urge to have a bowel movement that does not happen
-
Stools that have mucus in them
-
-
It is not clear what causes IBS. But stress, eating large meals, or travel may trigger the symptoms. Certain medications or foods can also cause symptoms to flare up. Caffeine, dairy products, and large amounts of alcohol can cause problems as well. Women may have more symptoms during their menstrual periods.
-
IBS cannot be cured, but it can be managed to reduce the symptoms. You may have tests to help rule out other conditions first.
Your health care professional or a nutritionist can suggest changes in your diet to help manage IBS. Eating frequent small meals rather than two or three large meals a day can help. In some cases, adding fiber to your diet may help. Your health care professional may also suggest medications to relieve the symptoms.
Inflammatory Bowel Disease Expand All
-
IBD is a group of diseases that cause inflammation throughout the digestive system. If inflammation does not go away, parts of the digestive system can be damaged. There are two main types of IBD:
- Crohn's disease can affect any part of the digestive system
- Ulcerative colitis usually affects the large intestine (also called the colon)
Symptoms of IBD may include the following:
- Abdominal pain
- Diarrhea that doesn't go away
- Fatigue
- Stools that have blood in them
- Weight loss
-
It's not clear what causes IBD, but it may be related to a problem with the immune system. Your genes may be a factor too. Your health care professional may do several tests to make sure that your symptoms are caused by IBD and not caused by an infection.
-
IBD is usually treated with medication first. But if the damage is severe, surgery may be an option.
Celiac Disease Expand All
-
People with celiac disease cannot tolerate gluten, a protein found naturally in wheat, rye, and barley. Gluten is also added to certain food products.
When gluten is eaten, the immune system reacts by damaging the lining of the small intestine. Because of this damage, nutrients cannot be absorbed properly.
Celiac disease is one of the most common digestive disorders, affecting about 1 in 133 people.
-
Some people with celiac disease have no symptoms. Others may have
-
diarrhea
-
constipation
-
fatigue
-
abdominal pain and bloating
-
-
If your health care professional thinks that you may have celiac disease, the first step is to have a blood test. This test looks for certain antibodies that show that the immune system is reacting against gluten. If the antibodies are found in your blood, you may have a biopsy of the intestine to look for damage and confirm the diagnosis.
-
If celiac disease is not treated, the disease can increase the risk of serious health problems, including osteoporosis, anemia, and cancer. Treatment involves avoiding gluten in your diet. Researchers are also studying medications that can make gluten less toxic to the small intestine.
Colorectal cancer Expand All
-
Colorectal cancer is cancer of the rectum and colon. It is the second leading cause of cancer death among women in the United States. In most cases, colorectal cancer develops slowly over time. It often begins as a polyp—a tissue growth in the colon or rectum.
Routine screening can help prevent colon cancer. Polyps that are found during routine screening can be removed easily before they become cancerous.
-
You are at high risk of colon cancer if you
-
have a first-degree relative (a parent or sibling) younger than 60 with colorectal cancer or colon polyps
-
have two or more first-degree relatives of any age with colorectal cancer or colon polyps
-
have had colorectal cancer
-
have had colon polyps
-
have a family history of familial adenomatous polyposis or hereditary nonpolyposis colon cancer
Lifestyle can play a role in your risk of colorectal cancer. The following factors can increase your risk:
-
Eating a diet that is low in fiber and high in fat
-
Not exercising regularly
-
Being overweight
-
Smoking cigarettes or drinking large amounts of alcohol
-
-
If you are at average risk of colon cancer, the preferred screening method is a colonoscopy done every 10 years beginning at age 45.
Screening with colonoscopy for people at high risk should begin at age 40, or 10 years younger than the age when the youngest affected relative received the diagnosis.
It is recommended that you stop having colonoscopy screening if you are older than 75.
-
Other screening methods include the following:
-
Fecal occult blood test or fecal immunochemical test every year—For this test, several stool samples are collected at home and are sent to a lab. The samples are checked for blood, which could be a sign of cancer of the colon or rectum.
-
Fecal DNA test every 1 to 3 years—DNA is the substance that makes up genes. Colon cancer cells contain abnormal DNA that can be detected with a special test.
-
Flexible sigmoidoscopy every 5 years—This test involves placing a thin device into the rectum and lower colon to look for cancer.
-
Computed tomography (CT) every 5 years—Sometimes called a "virtual colonoscopy," this imaging test allows the colon to be viewed without a colonoscope.
The type of screening test that you have is based on its risks, benefits, availability, and your preference. If you choose to have one of the other screening tests and you have an abnormal result, a follow-up colonoscopy is usually done.
-
-
Colorectal cancer usually shows no signs in the early stages of the disease. In the more advanced stages, signs and symptoms may include the following:
-
A change in bowel habits
-
Bleeding from the rectum
-
Blood in the stool
-
Stools that are more narrow than usual
-
Abdominal discomfort (bloating, cramps, or frequent gas pains)
-
A feeling that you need to have a bowel movement (that does not go away after a bowel movement)
-
Loss of appetite
-
Weakness and feeling tired
Having these symptoms does not mean that you have cancer. The same symptoms can be caused by other digestive disorders. Talk with your health care professional if you have any of these symptoms.
-
-
If your health care professional determines that you have colorectal cancer, there are several treatments available, including surgery, radiation therapy, chemotherapy, and more. Learn about cancer treatment by visiting the websites in the Resources section below.
