Tips for Managing Diabetes While Undergoing Cancer Treatment

Dealing with both diabetes and cancer treatment can feel overwhelming, but taking the right steps can make it manageable. Here are some tips to help you stay on track and maintain your health during this time.

Keep Your Doctors in the Loop

Let your cancer doctor, diabetes specialist, and family doctor know about all your treatments. Working together, they can adjust medications, monitor blood sugar levels, and create a meal plan that supports your recovery.

  • Make sure to share a list of all medicines and supplements you take.
  • Talk about any side effects so they can adjust your treatment if needed.
  • Regular updates ensure you’re getting the best care for both conditions.

Quick Tip: Bring all your prescriptions to each visit to avoid any mix-ups.

Check Your Blood Sugar Often

Cancer treatments like chemotherapy and steroids can cause your blood sugar to rise or drop unpredictably. Monitoring your levels more often than usual is key.

  • Use a glucose meter or a continuous glucose monitor to keep track.
  • Write down your readings, how you feel, and what treatments you’re on.
  • Look out for symptoms of high blood sugar (thirst, fatigue) or low blood sugar (dizziness, sweating).

Helpful Hint: Set alarms on your phone so you don’t forget to check.

Eat the Right Foods for Both Conditions

A balanced diet is essential when managing diabetes and going through cancer treatment. Work with a dietitian to create a meal plan that suits your needs. Include:

  • Lean proteins like chicken, fish, or tofu to help your body heal.
  • Whole grains, beans, and veggies that won’t cause big sugar spikes.
  • Healthy fats from sources like nuts, seeds, or olive oil.
  • Plenty of water to stay hydrated.

Avoid processed foods, sugary drinks, and alcohol since they can interfere with both conditions.

Stay Active Without Overdoing It

Exercise can help you control your blood sugar and feel more energetic. Depending on how you’re feeling, try:

  • Taking short walks or doing gentle yoga to relieve stress.
  • Using light weights to maintain strength if your energy allows.

Always check with your doctor before starting any new activities, especially if you’re feeling tired or unwell.

Take Care of Your Mental Health and Get Enough Rest

Coping with cancer and diabetes can be stressful, and stress can affect your blood sugar. Find ways to relax, like:

  • Practicing deep breathing or meditation.
  • Joining a support group to connect with others in similar situations.

Getting good sleep is just as important. Set up a calming bedtime routine and avoid caffeine late in the day.


Managing diabetes while undergoing cancer treatment is challenging but doable. By staying informed, working closely with your doctors, and making small lifestyle changes, you can take control of your health. Always ask your healthcare team for advice that fits your specific situation.
