Fatigue by itself is a symptom rather than a diagnosable condition. Patients may seek medical help for their feeling of fatigue without even realizing that gastrointestinal (GI) disorders are the source of their symptoms.

Once a GI disorder has been diagnosed by a physician, it can be treated, which should help relieve the feeling of fatigue. If a certain medication is found to be causing fatigue, a different drug may be prescribed in its place.

Other treatment and prevention methods for fatigue may include:

• Exercise. Many patients can help combat fatigue with regular exercise, which can improve mood, increase energy, stimulate appetite and boost endurance, strength and stamina.
  
  Patients should begin with short periods of low-intensity exercise, such as leisurely walking, and gradually increase the duration and intensity level of exercise over time (when appropriate). Many experts recommend at least 30 minutes of moderate activity on most days of the week. Some individuals with digestive system disorders may find it difficult to exercise. All patients should speak with their healthcare professional before beginning a new exercise regimen to determine whether exercise is appropriate for them and which exercises are most beneficial for their condition.
  
  
• Activity and rest. Patients who experience fatigue should set priorities for their daily activities and use a schedule to conserve their energy.  A physician can help devise an activity and rest program that allows the patient to conserve the maximum amount of energy. Patients may reduce fatigue and improve their sleeping habits by lying down only when ready to sleep, limiting daytime naps, increasing their activity level during the day, eliminating sources of distracting sounds when sleeping and avoiding foods before bedtime that may interfere with sleep.
  
  Patients should set realistic activity goals and avoid overexerting themselves by using equipment aids (e.g., a ramp instead of stairs or an electric cart at the supermarket). These aids can help patients reduce their energy expenditure. Patients may also benefit from enlisting the help of others when errands and housework become too difficult. In addition, patients who work may choose to speak with their employer about modified responsibilities and flexible scheduling if necessary. Many patients also benefit from maintaining an activity diary, which allows them to identify activities that are particularly taxing.
  
  
• Hydration and nutrition. Patients are typically advised to drink a minimum of eight glasses of liquids every day to remain sufficiently hydrated. They should not skip meals and are urged to eat a balanced and nutritious diet with sufficient calories, complex carbohydrates (vegetables and grains), proteins, fats and vitamins to provide sustained energy sources and help the body meet its escalating energy demands. It is best to avoid sugary cereals and juices and beverages that are caffeinated. Patients may choose to speak with a dietician regarding ways to maximize their nutritional intake. Patients may also benefit from taking a daily multivitamin.
  
  
• Stress. Patients experiencing fatigue may benefit from reducing their stress. This can be achieved by learning relaxation techniques, such as meditation and yoga. In addition, patients should try to avoid stress when possible. This may involve changing jobs or taking a vacation.

People experiencing fatigue should avoid stimulants. Caffeine and other stimulants are not effective in the treatment of fatigue because they may worsen the disorder in the long run by interfering with sleep. Alcohol, nicotine and illegal drugs should also be avoided. In addition, sedatives should not be taken by patients suffering from fatigue. These medications can also worsen the condition.  

Patients are encouraged to monitor the level of their fatigue and contact their physician if its severity increases.
