# Nutrition in Myelodysplastic Syndrome
Nutrients and blood cell production
In myelodysplastic syndrome (MDS), the bone marrow does not function properly, resulting in too few healthy blood cells. Certain nutrients play a role in normal blood cell formation.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Folate (vitamin B9) and vitamin B12 are essential for the division and maturation of blood cells. A deficiency in folate can even cause symptoms that resemble MDS, although this is rare.
In MDS patients, deficiencies in vitamins and minerals that are important for blood cell production are sometimes checked. This helps to understand what your body needs, but correcting a deficiency does not resolve the underlying MDS.
Nutritional side effects of treatments
Many MDS patients receive hypomethylating agents (such as azacitidine or decitabine).
ResearchediPositive results in clinical studies, not yet standard treatment
These medications can cause gastrointestinal disorders: nausea, vomiting, diarrhea, and loss of appetite have been reported. These side effects can vary from day to day and affect what you can eat and drink.
Some patients notice that certain foods are tolerated better than others, and this can vary greatly from person to person. A dietitian can help adjust meals at times when side effects are least severe.
Digestion and nutrient absorption
The gastrointestinal tract plays an important role in nutrient absorption.
ResearchediPositive results in clinical studies, not yet standard treatment
MDS patients sometimes experience changes in gut bacteria or reduced absorption of certain substances, especially with long-term treatment. This can mean that despite eating healthily, you absorb fewer nutrients than normal.
Stomach or intestinal problems can also result from infections, since MDS is accompanied by reduced immunity. This can further limit your nutritional intake. Your healthcare provider or dietitian can advise what measures may be helpful.
Minerals and nutrient interactions
ResearchediPositive results in clinical studies, not yet standard treatment
Some nutrients can interact with certain medications. There is also a small group of patients with very specific problems (such as copper deficiency after stomach surgery), which need to be monitored carefully. This type of complication is rare, but illustrates that nutrition and disease can be interrelated.
Furthermore, there is
ExperimentaliOngoing in study setting, outcome still unknown
Research into the role of certain metabolic products and nutrients in the development and progression of MDS, but this is not yet ready for practical recommendations.
Appetite fatigue
Fatigue and poor appetite are common problems in MDS, partly because the disease causes your body to use energy more efficiently.

Adequate nutrition helps maintain energy and muscle mass better, which is important for quality of life.
Many patients find that small, regular meals are better tolerated than three large ones. Meals at different times of the day may also feel better or worse. This is very personal. A dietitian can help map this out and adjust your nutrition to your daily rhythm and symptoms.
Communication around food and care
ResearchediPositive results in clinical studies, not yet standard treatment
Sharing meals with caregivers and loved ones contributes to well-being and social connection, which is especially important during intensive treatment. This does not directly affect nutrition, but underscores that eating also has a social and emotional dimension in chronic illness.
Nutritional supplements and herbs
UnproveniNo scientific evidence that it works
There is no strong evidence that certain nutritional supplements or herbal mixtures improve or prevent MDS. Some supplements can also interact with your medications or affect their functioning. Always discuss with your doctor or dietitian before adding supplements, especially since MDS treatments can sometimes be sensitive to certain substances.
Alcohol
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Alcohol can interfere with the functioning of certain MDS medications and increases the risk of gastrointestinal problems if you are already feeling nauseous or have diarrhea. This is especially true if your treatment weakens your immune system. Alcohol-free is safer, although a small amount occasionally is usually not a major risk.
Nutrition and infections
Because MDS weakens your immune system, food safety is important.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Good hygiene in food handling, avoiding insufficiently heated food and surface contamination help prevent infections. This is especially important if your white blood cells are very low. Your healthcare provider will tell you when you need to be extra careful.
Practical guidance
Your dietitian or nutritional advisor can best help you to:
- Adapt nutrition to medication side effects
- Ensure you get enough energy and proteins despite reduced appetite
- Limit infection risks when making food choices
- Prevent interactions between food and medications
- Maintain enjoyment and social aspects of eating
This is highly personal work that cannot be addressed in a general article.
