Cancer Fatigue: Why It Happens And How To Deal With It?

The exact causes and best treatments for cancer fatigue are sometimes unclear. See what doctors know about cancer fatigue and what you can do about it.

Fatigue, often described as feeling tired, weak, or exhausted, affects most people during cancer treatment. Cancer fatigue can be caused by side effects of treatment or by cancer itself.

Causes of Cancer Fatigue

Cancer fatigue can be caused by many factors, and the factors that cause your cancer fatigue may be completely different from others. However, possible triggers include:

Your cancer 

Cancer can cause changes in your body that can lead to fatigue. For example, some cancers release proteins called cytokines, which are thought to contribute to fatigue.

Other cancers can increase your body's need for energy, weaken muscles, cause damage to certain organs (such as the liver, kidneys, heart, or lungs), or alter your body's hormones, which can all lead to fatigue.

Cancer treatment Cause Fatigue

Chemotherapy, radiation therapy, surgery, bone marrow transplants, and biological treatments can all cause fatigue. When chemotherapy or radiation not only kills the targeted cancer cells, but also damages healthy cells, you may feel fatigued.

Fatigue can occur as your body tries to repair damaged healthy cells and tissues. Fatigue may also be caused by some side effects of treatment, such as anemia, nausea, vomiting, pain, insomnia, and mood changes.

Anemia Cause Fatigue

If the treatment you receive destroys too many healthy red blood cells, you may develop anemia. Anemia can also occur if cancer in your body has spread to the bone marrow, affecting the production of blood cells or causing blood loss.

Pain Cause Fatigue

 If you experience chronic pain, you may experience decreased activity, less food, less sleep, and depression, all of which may increase your fatigue.

Bad Mood Cause Fatigue

Anxiety, stress, or depression from a cancer diagnosis can also lead to fatigue.

lack of sleep. If you sleep less at night, or if your sleep is interrupted frequently, you may feel tired.

Malnutrition Cause Fatigue

To work effectively, you need a healthy diet to provide you with energy. When you have cancer, your body's need for and processing of nutrients can change. These changes can lead to malnutrition, which in turn can lead to fatigue.

For example, you may need more nutrients than usual, or your body may not be able to process nutrients adequately. You may also eat fewer nutrients if your appetite is reduced or if side effects from treatment (such as nausea and vomiting) make it difficult for you to eat.

The medical treatment causes Fatigue

Certain medications, such as pain relievers, can cause fatigue.

lack of exercise causes Fatigue

If you're used to the hectic pace of life, a sudden slowdown can leave you feeling fatigued. Life has its ups and downs, but if you can, try to maintain a normal daily activity level.

Hormonal changes cause Fatigue

During cancer treatment, many hormones change. Hormone therapy is a common treatment for certain cancers, and changes in hormones in the body can cause the body to experience significant fatigue. Hormonal changes can also manifest as side effects of certain treatments, such as surgery, radiation therapy, or chemotherapy. Changes in the thyroid, adrenal glands, testes, or ovaries can also cause fatigue.

Not every cancer patient experiences fatigue. If you have fatigue, your cancer fatigue level may vary: you may experience a slight lack of energy, or you may feel exhausted.

Your cancer fatigue can be episodic and only last for a short time, or it can last for several months after you finish treatment.

It is normal to experience some fatigue during cancer treatment. But tell your doctor if you find that cancer fatigue persists for weeks and interferes with your ability to perform daily tasks.
