Understanding and Managing Dizziness and Fatigue in Cancer Patients

Dizziness and fatigue often manifest as symptoms in people affected by cancer, resulting from a wide variety of potential causes. These symptoms may arise as a direct result of the cancer’s impact on the body or as adverse effects of the treatments administered to combat the disease.

Cancer, characterized by the uncontrolled spreading and division of cells leading to tumor formation, is estimated to result in over 1.9 million new diagnoses across the United States alone in just 2023, according to data from the American Cancer Society. ^(1,2)

Within the spectrum of cancer’s diverse array of symptoms, dizziness and fatigue stand out prominently. These manifestations can significantly impact an individual’s quality of life and may be indicative of various underlying factors associated with the disease or its treatment.

The experience of dizziness and fatigue among cancer patients often varies widely, with some attributing it directly to the tumor’s physical effects on the body. Meanwhile, others encounter these symptoms due to the systemic repercussions of cancer treatment, such as chemotherapy, radiation, or other therapies employed to curb the disease’s progression. ⁽³⁾

Understanding the intricate interplay between cancer, its treatments, and the resulting symptoms remains crucial in providing comprehensive care to individuals facing this challenging diagnosis. Therefore, addressing and managing dizziness and fatigue in cancer patients needs a multifaceted approach that considers the underlying cancer biology, treatment modalities, and the patient’s overall health and well-being. Let us gain some more insights into understanding cancer-related dizziness and fatigue.

Fatigue, an overwhelming sense of tiredness or exhaustion, is a prevalent issue among people dealing with cancer. Recent studies from 2023 suggest that approximately 40–70 percent of people diagnosed with cancer tend to experience fatigue, a stark contrast to the ten percent prevalence among the general population.⁽⁴⁾

The fatigue associated with cancer is actually distinctive, significantly impacting the quality of life for those affected. People with cancer often describe their fatigue as:

• Fluctuating from day to day
• Triggered by minimal activity
• Resistant to relief through rest or sleep
• Interfering with routine activities like household chores, work, or social engagements

Understanding the origins of cancer-related fatigue is complex and usually quite multifaceted, stemming from a combination of factors instead of just one cause.

It is important to understand that the impact of cancer on the body can directly contribute to fatigue through several mechanisms:

• Increased inflammation within the body due to cancer can lead to pervasive fatigue.
• Certain cancers may disrupt hormone levels, leading to pronounced fatigue.
• Blood cancers like leukemia and multiple myeloma can diminish the production of healthy red blood cells, resulting in anemia, a frequent cause of fatigue.
• Lung cancer, by impairing oxygen levels and causing shortness of breath, often results in rapid exhaustion and fatigue.

Fatigue is also a major side effect of various cancer treatments, including:

• Chemotherapy
• Radiation therapy
• Immunotherapy
• Hormone therapy ⁽⁵⁾
• Surgery

Though the precise mechanisms linking these treatments to fatigue remain unclear, chemotherapy-induced anemia is another common contributor to fatigue, as highlighted by the National Cancer Institute. ⁽⁶⁾

There are also many other elements that can aggravate cancer-related fatigue. These include:

• Emotional factors like anxiety or depression can intensify feelings of fatigue.
• Changes in sleep patterns or inadequate sleep quality can exacerbate fatigue levels.
• Alterations in nutritional needs or intake might impact energy levels.
• Non-cancer-related medications used alongside cancer treatments may also contribute to fatigue.

Recognizing the diverse interplay between cancer, its treatments, and the many other associated factors is highly important in addressing and managing the debilitating effects of fatigue in people going through a cancer diagnosis and treatment regimen. ⁽⁷⁾

Dizziness is a disorienting sensation characterized by feeling lightheaded, unsteady, or as if one might faint. It is important to differentiate it from vertigo, a condition where individuals perceive either themselves or their surroundings to be spinning.

For individuals navigating cancer, experiencing bouts of dizziness may stem from various causes, including:

1. Direct Impact of the Cancer Itself

   • Brain Tumors: Cancer affecting the brain can directly lead to dizziness due to its influence on neurological functions and equilibrium.

2. Effects of the Cancer or its Treatment

   • Anemia: Often a consequence of cancer or cancer treatments, anemia results in reduced red blood cell count, leading to decreased oxygen supply to tissues and contributing to dizziness. ⁽⁸⁾
   • Side Effects of Treatments: Cancer therapies like radiation to the brain, chemotherapy, or specific hormone therapies may induce dizziness as a side effect..⁽⁹⁾

3. Psychological Factors

   • Stress and Anxiety: Emotional distress related to the cancer diagnosis or treatment journey can manifest physically, potentially causing dizziness.
   • Dehydration
   • Nausea, Vomiting, or Diarrhea: These are common side effects of both cancer and cancer treatments, leading to dehydration, electrolyte imbalances, and subsequently, dizziness.

4. Impact of Medications

   • Non-Cancer related Medications: Some medications used in managing cancer-related symptoms or coexisting conditions might trigger dizziness. This includes antidepressants, anti-seizure drugs, and certain blood pressure medications.

   Recognizing the complex nature of dizziness in the context of cancer is important for its appropriate management. Addressing the underlying causes, whether directly related to the cancer, its treatments, or associated factors, is crucial in relieving this distressing symptom for individuals undergoing the challenges of cancer diagnosis and treatment. Consulting your healthcare provider is very important to get an accurate diagnosis and to help your doctor come up with a customized management strategy to deal with the dizziness.

Managing cancer-related fatigue and dizziness involves a comprehensive approach that addresses the underlying causes and aims to improve overall well-being. Here are several strategies and approaches that can help in managing these symptoms:

1. Consult Healthcare Professionals: Seek guidance from your healthcare team, including oncologists, nurses, and specialized therapists. They can assess your condition, identify potential causes, and provide personalized recommendations.
2. Regular Exercise: Engage in mild to moderate physical activity as tolerated. Exercise can help combat fatigue, improve energy levels, and enhance overall well-being. Consult your healthcare provider before starting any exercise program.
3. Balanced Nutrition: Maintain a healthy and balanced diet rich in nutrients. Ensure adequate hydration, as dehydration can exacerbate dizziness. A registered dietitian can help design a diet plan tailored to your needs.
4. Manage Stress and Anxiety: Practice stress-relieving techniques such as mindfulness, meditation, yoga, or deep breathing exercises. Counseling or support groups may also assist in coping with emotional distress.
5. Energy Conservation: Prioritize tasks and conserve energy by breaking tasks into smaller, manageable segments. Take regular breaks and rest when needed to prevent fatigue from worsening.
6. Establish a Sleep Schedule: Establish a regular sleep schedule and create a restful sleep environment. Good sleep hygiene can significantly improve fatigue levels.
7. Manage your Medication: Discuss with your healthcare provider the medications contributing to dizziness or fatigue. Adjustments in medication doses or alternative treatments may help alleviate these symptoms.
8. Supportive Therapies: Consider complementary therapies such as acupuncture, massage, or relaxation techniques, which may help alleviate fatigue and improve overall well-being.
9. Address Anemia: If anemia is a contributing factor, treatments such as iron supplements or red blood cell transfusions may be recommended to improve fatigue.
10. Hydration and Nutrition: Ensure adequate fluid intake and a well-balanced diet. Consult with a healthcare provider or nutritionist for guidance on managing side effects that affect eating and drinking.
11. Mobility and Balance Exercises: Physical therapy or occupational therapy may offer exercises to improve balance and reduce dizziness.

Remember that every person’s experience with cancer-related fatigue and dizziness is unique. Tailoring a management plan with the guidance of healthcare professionals ensures a holistic approach to relieve these symptoms.

Navigating cancer-related dizziness and fatigue demands a multifaceted approach that should include personalized care and collaboration with your doctors.
