The causes of severe fatigue in cancer patients are multifactorial. Key contributors include:
Cancer Treatments: Chemotherapy, radiation therapy, and surgery can all lead to fatigue. These treatments can damage healthy cells and tissues, causing the body to expend more energy on repair and recovery. Anemia: Many cancer patients develop anemia, which reduces the oxygen-carrying capacity of the blood, leading to increased fatigue. Nutritional Deficiencies: Cancer and its treatments can affect appetite and nutrient absorption, leading to deficiencies that contribute to fatigue. Pain and Sleep Disturbances: Chronic pain and disruptions in sleep patterns can exacerbate feelings of fatigue. Emotional Distress: Anxiety, depression, and stress related to the cancer diagnosis and treatment can also play a significant role.
