Nutrition During Multiple Myeloma Treatment

Nutrition is an important part of supportive care during myeloma treatment, though specific dietary guidance should come from your healthcare team. Let me explain what's generally important and what challenges you might face.

Why Nutrition Matters During Treatment

According to the NCCN Guidelines for Multiple Myeloma, supportive care is a critical part of treatment alongside the cancer-fighting medications. Good nutrition helps:

  • Maintain strength and energy during treatment cycles
  • Support immune function (important since myeloma affects white blood cells)
  • Help the body recover between treatment cycles
  • Manage side effects like nausea, loss of appetite, and mouth sores
  • Protect kidney function (since myeloma can affect the kidneys)

Common Treatment Side Effects That Affect Eating

The NCCN Guidelines note that common side effects of myeloma medications include:

  • Nausea and vomiting
  • Loss of appetite
  • Diarrhea or constipation
  • Mouth sores
  • Fatigue and weakness
  • Changes in taste

These side effects make eating challenging, so food choices matter.

General Nutrition Principles

Protein is especially important because:

  • It helps rebuild muscle and tissue damaged by treatment
  • It supports immune function
  • It helps with wound healing and recovery

Good protein sources include:

  • Eggs and dairy (yogurt, cheese, milk)
  • Chicken, fish, and lean meats
  • Beans and legumes
  • Nuts and nut butters
  • Protein shakes or supplements

Calories matter because treatment is demanding on the body. If appetite is low, focus on nutrient-dense foods rather than large portions.

Hydration is critical, especially since:

  • Some myeloma medications require good hydration
  • Kidney function needs to be protected
  • Dehydration worsens fatigue and nausea

Special Considerations for Myeloma Patients

Kidney function: The NCCN Guidelines emphasize that up to 33% of myeloma patients have kidney compromise at diagnosis. Your care team may recommend:

  • Limiting sodium in some cases
  • Monitoring protein intake (your doctor will advise the right amount)
  • Staying well-hydrated

Bone health: Since 80% of myeloma patients have bone disease, adequate calcium and vitamin D are important—though your doctor should guide supplementation since some myeloma treatments affect mineral metabolism.

Infection risk: With reduced white blood cells, food safety matters:

  • Cook foods thoroughly
  • Avoid raw or undercooked meats, eggs, and seafood
  • Wash produce carefully
  • Be cautious with unpasteurized dairy

Practical Tips When Appetite is Low

  • Smaller, frequent meals instead of three large ones
  • Cold foods (smoothies, yogurt, ice cream) if hot foods cause nausea
  • Bland foods during nausea: crackers, toast, rice, applesauce
  • Ginger tea or peppermint may help with nausea (ask your doctor first)
  • Nutritional supplements like Ensure or Boost if eating solid food is difficult
  • Favorite foods when appetite allows—don't force "healthy" foods if they cause nausea

When to Get Professional Help

Ask your care team for a referral to a registered dietitian who specializes in oncology. They can:

  • Create a personalized nutrition plan based on your specific treatment
  • Address kidney function concerns
  • Manage medication interactions with food
  • Help with specific side effects you're experiencing

Important Reminders

The NCCN Guidelines emphasize that supportive care is individualized—what works for one person may not work for another. Your specific needs depend on:

  • Which medications you're taking
  • Your kidney and liver function
  • Other medical conditions
  • Your specific side effects
