Fatigue and low energy are really common with breast cancer and its treatments — you're definitely not alone in feeling this way! Before starting any vitamins or supplements, it's really important to check with your oncologist or care team first, as some can interfere with treatments like Xeloda (capecitabine).
That said, here are some general areas your doctor may explore to help with fatigue:
- Anemia — low red blood cell counts from treatment can cause tiredness, and iron or B12 may be recommended if levels are low
- Vitamin D — often checked in breast cancer patients, as low levels can contribute to fatigue
- Magnesium — sometimes depleted during treatment and linked to low energy
Your doctor may also refer you to a registered dietitian who specializes in cancer care to build a nutrition plan tailored to your needs. Beyond vitamins, a few practical things that MyBCTeam members have found helpful for fatigue include:
- Staying well hydrated — dehydration is a surprisingly common cause of tiredness
- Eating small, protein-rich meals or smoothies when appetite is low
- Gentle movement like short walks when energy allows
- Accepting help from friends and family so you can conserve your energy for healing
Always loop in your care team if fatigue is getting worse or keeping you in bed — they can help find the root cause.
