# Nutrition in myelofibrosis
Nutritional status and survival
Research suggests that the nutritional status of patients with myelofibrosis may be important for their overall health and life expectancy.

A study of patients with myelofibrosis showed that certain nutritional factors are associated with how long patients survive. This suggests that paying attention to nutrition can be part of your overall care, but it does not mean that nutrition can cure or accelerate the disease.
Because myelofibrosis can lead to pallor, fatigue and weakness, regular nutrition plays a role in maintaining your strength. Many patients suffer from weakness due to anemia that develops from the disease. A doctor or dietitian can advise how to best support your body's reserves.
Iron metabolism and nutrition
Myelofibrosis affects the release of hepcidin, a substance produced by the body that regulates iron uptake and storage.

This means that iron metabolism in the body can become disrupted. In some patients, secondary iron accumulation can occur, especially when they receive multiple blood transfusions.
If you need regular transfusions, this can lead to iron overload. Nutrition then plays a supportive role: some nutrients can reduce iron uptake, others increase it. However, this is very individual and depends on your specific situation and treatment. Discuss this with your doctor or dietitian — they can help you understand what is relevant for your situation.
Proteins and muscle strength
In chronic diseases such as myelofibrosis, there is a risk of muscle loss, especially when you are tired and less able to be active.

Adequate protein intake can help you maintain your muscle mass. This is especially important because muscle strength affects your ability to perform daily tasks and your overall wellbeing.
Protein-rich foods are naturally accessible to many people through meat, fish, dairy products, legumes and nuts. If eating is difficult for you due to side effects of treatment or symptoms of the disease, a dietitian can help with practical adjustments.
Nutrition and side effects of treatment
The medications used against myelofibrosis — particularly JAK inhibitors such as ruxolitinib — can have side effects that affect nutrition.

Some patients experience nausea, changes in appetite or stomach complaints. Also, nutrients such as vitamin B12 and other essential substances may be more difficult to absorb.

Recent research has looked at whether nutritional counseling via telehealth (digital contact) can help patients with myeloproliferative disorders better manage nutrition and side effects. This shows that nutritional support is increasingly being recognized as part of care.
Questions about nutrition therefore belong in conversations with your treatment team. Many hospitals have dietitians who know how nutrition and treatments are related.
Vitamins and minerals
Anemia and the deficiencies that come with it sometimes mean you need more attention to certain nutrients.

Vitamin B12 deficiency, for example, can cause symptoms that resemble myelofibrosis. This can occur when nutrient uptake is disrupted.
Iron, folic acid, vitamin B12 and other B vitamins play a role in blood formation. Whether you need *more* of these depends on your own situation — not on the disease alone. Many patients have blood tests in which these values are measured. Your healthcare provider can then see if supplementation is useful.
**Starting supplements on your own without consulting your doctor is not recommended.** Some supplements can interact with your medications, or can adversely affect the disease.
Eating and energy: practical tips
Because fatigue is a major symptom of myelofibrosis, eating itself can become a challenge. You may have less energy to cook, or you have little appetite. This is completely normal and not a personal failure.
Small, regular meals work better for many people than three large meals. Moist food is sometimes easier to eat than dry food. If chewing is tiring, soups, smoothies and soft food can help. Your dietitian can provide many practical ideas that suit what you can manage.
Eat something you prefer, even if it's not "ideal" — it's better to have eaten something you really want than not to eat at all because you're hungry.
Nutrition and complementary treatments
Many patients are curious about nutritional supplements, herbs or other natural remedies.

Recent research shows that patients with myelofibrosis are indeed interested in complementary and alternative medicine. This is understandable, but caution is warranted.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Many herbs and supplements can affect the effectiveness of your medicines or cause interactions. Some can also pose risks when you have certain blood disorders. Always tell your doctor which supplements, herbs or tea you use — even if you think it's harmless.
There is currently no evidence that special nutrition or supplements can cure myelofibrosis or substantially change it.
UnproveniNo scientific evidence that it works
Be cautious of claims that promise this.
Fluids and nutrition with physical changes
Myelofibrosis can sometimes lead to enlargement of the spleen and liver, which can affect digestion and how your stomach feels. Some patients feel full quickly, or experience stomach cramps. This may mean your eating pattern needs to be adjusted — smaller portions, food that is easier to digest, more attention to fluids.
Drinking enough is important, especially with certain medicines. Water, tea and soups also count towards this. Your healthcare provider can indicate whether fluid intake is a particular concern in your situation.
How medicines and nutrition work
Some medicines for myelofibrosis work better or differently depending on when you take them and whether you have eaten.

This is very specific to each medicine and agreed upon with your doctor — he or she will tell you whether you should take your medicine with food or not.
Nutrients can also influence how your body processes certain medicines. For example: grapefruit can significantly change the effect of certain medicines. You'll receive this kind of information as standard with your medicine, and your pharmacist can also answer any questions you have.
Working together with your treatment team
If you have questions about nutrition and myelofibrosis, your doctor and dietitian are your best sources. They know your specific situation, your blood values, your medicines and your physical condition. They can recognize when nutrition needs support, and when certain supplements are or are not safe.
Many hospitals and treatment centres offer nutritional counselling to patients with myelofibrosis. This is not a luxury, but part of good care.
