How is fatigue diagnosed?
To diagnose fatigue, the doctor usually recommends a full physical examination to look for some underlying signs of illness. The examination with evaluation of the different systems of the body combine any abnormal findings with the clues found in the history taking may help make the diagnosis.
Special attention may be taken to palpate for an abnormal thyroid gland, swollen lymph nodes, listen for abnormal heart sounds including murmurs and to check for normal muscle tone and reflexes.
Depending on the findings in the history and physical examination, blood tests, and other imaging studies may be ordered.
How is fatigue treated?
Since fatigue is a symptom of an underlying condition, the treatment depends on the cause, regardless of whether it is physical, psychological or a combination of the two.
There may be a lag time between when the illness has been treated and the intensity of fatigue symptoms; some symptoms may resolve as soon as the underlying condition is treated.
Lifestyle changes & Home remedies
What are some lifestyle changes or home remedies that can help me manage fatigue?
More importantly, the early recognition of fatigue will allow a person to seek medical care and potentially have an earlier diagnosis of the underlying cause.
Sometimes, symptoms like fatigue arise gradually and it is difficult for the person to realize that there is a problem. It may take an outside perspective from a friend or family member to appreciate a difference in function. Self-awareness of gradual decline in body performance is often difficult as a person makes repeated small accommodations to complete daily activities.
If you have any questions, please consult with your doctor to better understand the best solution for you.
