What should I eat during Multiple Myeloma treatment

Nutrition During Multiple Myeloma Treatment

I appreciate this important question about supporting your health during treatment. While the NCCN Guidelines for Multiple Myeloma focus primarily on cancer-directed therapies, nutrition is a critical part of your overall supportive care. Let me explain what you should know and discuss with your care team.

Why Nutrition Matters During Myeloma Treatment

During multiple myeloma treatment, your body faces several challenges:

• Treatment side effects can affect appetite and digestion (nausea, vomiting, diarrhea, mouth sores, constipation)
• Weakened immune system from both the disease and treatment increases infection risk
• Increased nutritional demands as your body works to heal and recover
• Organ stress, particularly kidney function, which myeloma can affect

According to the NCCN Guidelines for Supportive Care, nutrition support is an essential component of cancer treatment, though specific dietary recommendations are individualized based on your particular situation.

General Nutritional Principles

Protein is especially important because:

• It helps rebuild healthy cells damaged by treatment
• It supports immune function
• It helps maintain muscle mass

Adequate calories help your body:

• Tolerate treatment better
• Maintain strength and energy
• Support healing

Hydration is critical because:

• The NCCN Guidelines note that kidney health is a major concern in myeloma—adequate hydration helps protect kidney function
• Treatment side effects can cause fluid loss
• Some myeloma treatments require good hydration to work safely

Foods to Consider (General Guidance)

Protein sources:

• Lean meats, poultry, fish
• Eggs
• Dairy products (if tolerated)
• Beans, legumes, nuts
• Protein supplements if eating is difficult

Nutrient-dense foods:

• Fruits and vegetables (when tolerated)
• Whole grains
• Healthy fats (olive oil, avocado, nuts)

Foods to be cautious about:

• Raw or undercooked foods (infection risk with low white blood cell counts)
• High-sodium foods (may affect kidney function)
• Foods that trigger your specific side effects

Important Considerations for Your Situation

Kidney function: The NCCN Guidelines emphasize that renal (kidney) disease management is critical in multiple myeloma. This may affect:

• Sodium intake
• Protein amounts (your doctor will advise)
• Fluid intake
• Certain minerals

Individual variation: Your specific nutritional needs depend on:

• Which myeloma treatment you're receiving
• Your kidney function
• Your specific side effects
• Other medical conditions you have

What You Should Do

This is a conversation for your care team. According to the NCCN Guidelines, supportive care—including nutrition—should be tailored to YOUR specific situation. I recommend asking your oncology team:

1. Should I see a registered dietitian? (Many cancer centers have dietitians experienced with myeloma patients)
2. Are there specific foods I should avoid based on my treatment plan?
3. How much protein should I aim for daily?
4. Are there concerns about my kidney function that affect what I eat?
5. What should I do if I'm experiencing nausea, loss of appetite, or other side effects that make eating difficult?
6. Are there nutritional supplements you recommend?
7. How much fluid should I be drinking daily?

Additional Resources

The American Cancer Society and NCCN Guidelines for Supportive Care both provide nutrition guidance for cancer patients. Your oncology center may also have printed materials or resources specifically about nutrition during myeloma treatment.
