Excessive fatigue is an abnormal level of tiredness. It is normal for a person to feel tired from time to time, especially at the end of a hard day’s work, but some people feel tired most of the time. For example, a person with excessive fatigue may feel tired when he wakes up in the morning and deal with fatigue throughout his day; he may also feel unable to muster the energy for everyday tasks as well as activities he usually enjoys. The causes can be numerous and varied. For example, a person may battle with extreme fatigue because of everything from depression and insomnia to kidney disease and fibromyalgia.

An individual who is excessively fatigued may feel exhausted bodily as well as mentally. For example, a person who is dealing with extreme fatigue may find keeping up with normal tasks difficult. He may have a difficult time handling such things as cooking and cleaning, and he may even feel too tired to perform personal care tasks. For example, simple tasks such as combing one’s hair and shaving may seem tiring when a person is dealing with excessive tiredness. Often, a person with this level of fatigue feels as if he is dragging through the day instead of being energetic for at least part of it.


In many cases, excessive fatigue makes it difficult for a person to participate in social activities. For example, a person who normally likes to be the center of attention may have trouble mustering the energy to attend a party if he is excessively fatigued. Likewise, a person dealing with this condition may not have the energy to play with his children or grandchildren as often as he would like.

Often, a person who is dealing with extreme fatigue notes not only a feeling of physical exhaustion, but also one of mental exhaustion. For example, his fatigue may interfere with his ability to concentrate on employment tasks or school work. He may also have difficulty making decisions or demonstrating enthusiasm.

There are many conditions that may cause excessive fatigue. An individual may suffer from it in relation to a sleep disorder, depression, chronic fatigue disorder, or disease that affects the immune system. Sometimes extreme fatigue may be a symptom of organ failure as well. Since this condition can be a symptom of a serious health condition, an individual may do well to seek a doctor’s advice if it persists.

@ZipLine-- There are actually many causes of excessive fatigue. There is no way to know about your health without seeing a doctor. I suggest making an appointment as soon as possible and get routine blood work and checkup. Also explain to your doctor all of these symptoms.

I don't want to give you any wrong ideas, but it could be depression related or it could be a metabolic syndrome problem due to abnormal blood sugar.

For example, my sister has Type 2 diabetes and she also experiences more than usual fatigue because of her condition. It has to do with the sudden changes in her blood sugar as well as the side effects of her medication.

Excessive thirst is also a diabetes symptom, along with fatigue. Your doctor should do a three hour glucose tolerance test in addition to other testing.

I have been experiencing excessive thirst and fatigue lately. I have all of the fatigue symptoms mentioned here. Sometimes I also feel dizzy and the fatigue comes on very suddenly. What could be the cause? I'm only in my twenties.

I had excessive and constant fatigue when I had hypothyroid. I was just tired all the time. I never wanted to get out of bed. I would sleep till late and sit around all day. It was so hard to even go out for a walk. If I did any activity, I would get tired and had to rest. It was awful.
