# Nutrition in Hodgkin lymphoma
Nutritional status and prognosis
In Hodgkin lymphoma, the outcome of treatment depends not only on the stage of the disease, but also on how well someone is physically conditioned at the time treatment begins.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Studies show that people with good nutritional status are better able to tolerate intensive therapies and experience fewer complications.
This does not mean you should gain or lose weight: it is about having sufficient proteins, vitamins and energy in your body to support the healing process. In people who are underweight or lose weight rapidly before treatment, doctors more often see difficulties arise. Therefore, many treatment centers check nutritional status beforehand.
Nutrition during chemotherapy and radiation
Chemotherapy for Hodgkin lymphoma can severely strain the digestive system.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many people experience nausea, vomiting, altered taste, dry mouth or esophagitis, especially with chemotherapy combined with radiation to the chest or neck.
These side effects can prevent you from eating or drinking enough. Right now your body needs a lot of energy and building blocks to recover from the damage caused by treatment. A nutritionist or dietitian can help:
- Adapt meals to what you can eat (softer, moister, in smaller portions)
- Control nausea and vomiting through timing and type of food
- Get enough calories and proteins, also through drinks if solid food is difficult
- Spare an inflamed esophagus by postponing certain foods (spicy, acidic, hot)
Vegetables, fruit and whole grain products are healthy, but much fiber can be painful if your intestines are irritated. This requires individualized care.
Infection risk and food choices
During chemotherapy your immune system is weak.
ResearchediPositive results in clinical studies, not yet standard treatment
Although classical advice about raw food is sometimes given very strictly, the actual risk depends on how low your white blood cell count drops. Many centers therefore provide flexible guidelines.
In general, caution is recommended with:
- Raw fish, meat and unpasteurized dairy
- Heavy bacterial load (for example old food, leafy greens that have been sitting)
- Certain herbs and supplements that can alter immune signals
However, this is not a universal rule: your doctor or dietitian will advise based on your white blood cell counts at that time.
Interactions between nutrition and medication
ProveniIncluded in official guidelines, or approved by EMA or FDA
Certain foods can alter the effect of medicines. This applies especially to grapefruit and grapefruit juice, which affect enzyme activity in your body. If you are taking certain targeted agents or supportive medications, this may be important.
Alcohol can worsen the side effects of certain chemotherapy drugs and prolong nausea and fatigue. Also, alcohol can make certain anti-nausea or anti-infection medications less effective.
Supplements (vitamins, minerals, herbs, homeopathy) can cause interactions.

Many people take extra vitamins because they feel weak, but high doses of some vitamins can actually interfere with chemotherapy or immunotherapy, or worsen certain side effects. This should be discussed with your doctor before you start supplements.
Nutrition after treatment
After chemotherapy ends, the digestive system gradually recovers. Many people feel fatigued for weeks to months and have difficulty getting their weight back to normal. This is normal: the body repairs itself slowly.
ProveniIncluded in official guidelines, or approved by EMA or FDA
A regular eating and drinking pattern helps keep the digestive system stable and supports recovery. Foods rich in proteins (meat, fish, eggs, legumes, dairy) help rebuild muscle tissue.
ResearchediPositive results in clinical studies, not yet standard treatment
Some research suggests that inflammation markers in blood are lower when people regularly eat vegetables and fruit and consume less processed food. This may be relevant because inflammation and immune signals play a role in recurrence risk, but this does not mean that certain diets 'prevent cancer'.
Supplements and complementary nutrition
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
'miracle cures' that cure cancer do not exist. Much internet content promotes certain supplements, herbs or diets that would make cancer disappear. There is no scientific evidence for this.
ExperimentaliOngoing in study setting, outcome still unknown
Some nutrients such as certain vitamins, antioxidants or immune boosters are being studied in clinical trials, but have not yet been shown to be effective and can be harmful in high doses during treatment. Individual use on your own initiative, without your doctor's permission, is unwise.
Prevent underweight and weight loss
If you notice that you are not eating, have a bad taste in your mouth, severe nausea or no appetite, report this immediately.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Early intervention, for example with nutritional support drinks or anti-nausea medication, prevents you from falling into a downward spiral of weight loss and weakening.
This is not only cosmetic: body mass helps against side effects of treatment and infections. A dietitian can help adapt recipes, plan small frequent meals, or prepare tube feeding if eating becomes impossible.
Practical: what you can do yourself
- **Discuss nutrition actively with your treatment team.** Many hospitals have dietitians or nutrition specialists; ask about it.
- **Eat what you can and what you enjoy,** as long as it is cautious. Do not force yourself to eat food that makes you nauseous.
- **Drink enough,** especially water. Dehydration worsens fatigue and constipation.
- **Avoid experimenting with diets or supplements yourself;** ask your doctor first.
- **Recognize that nutrition is support, not cure.** Your treatment cures; nutrition helps your body endure it.
