Multiple Sclerosis and Fatigue

Medically speaking, fatigue is not the same thing as tiredness. Tiredness happens to everyone -- it is an expected feeling after certain activities or at the end of the day. Usually you know why you are tired and a good night's sleep solves the problem.

Fatigue is a daily lack of energy; unusual or excessive whole-body tiredness not relieved by sleep. It can be acute (lasting a month or less) or chronic (lasting from one to six months or longer). Fatigue can prevent a person from functioning normally and affects a person's quality of life.

What to Expect With Primary Progressive MS

For Mimi Mosher, a person with primary progressive MS, clarity first came when she lost her vision. Her eyesight steadily eroded by multiple sclerosis, Mimi now lived in a near-constant dusk. The realization came at a scary time. “I was driving. I thought, I can’t do this anymore. I had to pull off the road and let my friend drive,” says Mimi. Until then, Mimi had been living “in a deep state of denial” about her advancing symptoms. As her primary progressive MS forced her to hand over her car...

According to the National Multiple Sclerosis Society, 80% of people with MS have fatigue. MS-related fatigue tends to get worse as the day goes on, is often aggravated by heat and humidity, and comes on more easily and suddenly than normal fatigue.

What Can I Do About MS-Related Fatigue?

The best way to combat fatigue related to your MS is to treat the underlying medical cause. Unfortunately, the exact cause of MS-related fatigue is often unknown, or there may be multiple causes. However, there are steps you can take that may help to control fatigue. Here are some tips:

1. Assess your personal situation.

  • Evaluate your level of energy. Think of your personal energy stores as a "bank." Deposits and withdrawals have to be made over the course of the day or the week to balance energy conservation, restoration, and expenditure. Keep a diary for one week to identify the time of day when you are either most fatigued or have the most energy. Note what you think may be contributing factors.
  • Be alert to your personal warning signs of fatigue. Fatigue warning signs may include tired eyes, tired legs, whole-body tiredness, stiff shoulders, decreased energy or a lack of energy, inability to concentrate, weakness or malaise, boredom or lack of motivation, sleepiness, increased irritability, nervousness, anxiety, or impatience.

2. Conserve your energy.

  • Plan ahead and organize your work. For example, change storage of items to reduce trips or reaching, delegate tasks when needed, and combine activities and simplify details.
  • Schedule rest. For example, balance periods of rest and work and rest before you become fatigued. Frequent, short rests are beneficial.
  • Pace yourself. A moderate pace is better than rushing through activities. Reduce sudden or prolonged strains. Alternate sitting and standing.
  • Practice proper body mechanics. When sitting, use a chair with good back support. Sit up with your back straight and your shoulders back. Adjust the level of your work. Work without bending over. When bending to lift something, bend your knees and use your leg muscles to lift, not your back. Do not bend forward at the waist with your knees straight. Also, try carrying several small loads instead of one large one, or use a cart.
  • Limit work that requires reaching over your head. For example, use long-handled tools, store items lower, and delegate activities whenever possible.
  • Limit work that increases muscle tension.
  • Identify environmental situations that cause fatigue. For example, avoid extremes of temperature, eliminate smoke or harmful fumes, and avoid long hot showers or baths.
  • Prioritize your activities. Decide what activities are important to you, and what could be delegated. Use your energy on important tasks.
