Managing Nausea and Fatigue During Breast Cancer Treatment

These are two of the most common side effects you may experience, and the good news is that there are proven strategies to help manage both. Let me break down what you can do.

Managing Nausea

According to the NCCN Guidelines for Patients: Invasive Breast Cancer, nausea and vomiting are common side effects of treatment, and your care team will provide you with medication to help prevent them before they start.

Medication approach:

  • Ask your doctor about anti-nausea medications (called antiemetics) that you can take before you feel sick, rather than waiting until nausea develops
  • Taking these medications preventively is often more effective than treating nausea after it starts

Non-medication strategies:

  • Eat smaller, more frequent meals rather than large ones
  • Avoid heavy meals directly before and after treatment
  • Try ginger tea or peppermint tea, which some patients find soothing
  • Eat cold foods when possible
  • Stay well-hydrated with fluids throughout the day
  • Avoid foods with strong smells that might trigger nausea

Quick relief tip: If you need immediate relief, try sniffing an alcohol wipe—some patients find this surprisingly helpful for quick nausea relief.


Managing Fatigue

Fatigue is extreme tiredness and a lack of energy that can interfere with your daily activities. According to the NCCN Guidelines for Patients: Invasive Breast Cancer and Metastatic Breast Cancer, fatigue may be caused by the cancer itself, by your treatment, or by emotional stress. The good news is there are multiple ways to address it:

Physical activity:

  • This is one of the most important things you can do. Staying active and engaged actually reduces fatigue rather than making it worse
  • Even gentle exercise like walking can help
  • Yoga and stretching can also be beneficial

Nutrition:

  • Eat a balanced diet with adequate protein to maintain your strength
  • A registered dietitian can help you create a nutrition plan that works for you, especially if eating is difficult
  • Focus on nutrient-dense foods when your appetite is limited

Complementary approaches:

  • Yoga and stretching
  • Acupuncture
  • Massage therapy
  • Meditation and deep breathing exercises

Emotional support:

  • Fatigue can be linked to depression, anxiety, or emotional stress related to your diagnosis
  • Talk to your care team about how you're feeling—there are counseling services and support groups available
  • Addressing emotional distress can help reduce fatigue

When to ask for help:

  • Tell your care team if fatigue is getting in the way of activities you enjoy
  • You may be referred to a nutritionist or other specialist to help address the underlying causes
  • Your doctor can also evaluate whether other factors (like anemia or medication side effects) are contributing

Key Questions to Ask Your Healthcare Team

  1. About nausea: "What anti-nausea medications do you recommend I take before treatment, and when should I take them?"

  2. About fatigue: "Are there specific types of exercise or physical activity you recommend for me during treatment?"

  3. About nutrition: "Should I see a registered dietitian to help manage my appetite and energy levels?"

  4. About emotional support: "What counseling or support services are available to help me manage the emotional aspects of treatment?"

  5. About monitoring: "How will you monitor my fatigue and nausea, and when should I contact you if these side effects are getting worse?"


Important Reminder

The NCCN Guidelines emphasize that it's crucial to tell your care team about all your side effects so they can be managed effectively. Don't try to tough it out silently—your medical team has many tools available to help you feel better and maintain your quality of life during treatment.
