Fatigue is not only tiredness that usually comes with physical exercise, but it is rather overwhelming exhaustion that does not improve after taking a nap or a good night’s sleep. People with chronic fatigue feel this way for weeks or months, and it often signals either depression and anxiety, a hormonal disease like thyroid disease, or a severe health problem like cancer.
In most patients with cancer, there is a reduction in their blood cell count, which is the type of cell that carries oxygen to the rest of the body. This is even more prevalent if lymphoma Is actually affecting the bone marrow, where red blood cells are created. Thus, patients feel tired easily and become lightheaded and drowsy all the time.
Additionally, cancer cells themselves are always craving for energy and will uptake more nutrients and oxygen than we can possibly think. In the process, cancer consumes extra energy and reduces our energy levels to the minimum.
