# Nutrition for spinal muscle atrophy
Nutrition as support for muscle disease
In spinal muscle atrophy (SMA), muscles are weakened, including those involved in eating and drinking. This can make it difficult to eat and drink. A good nutritional condition helps keep the body stronger and supports the healing process during treatment. Nutrition is therefore not an afterthought, but part of healthcare.
Swallowing and food intake
**Swallowing problems occur, especially in SMA types 1 and 2**
In SMA, the muscles in the mouth, throat, and esophagus may be weakened. This may result in:
- swallowing is more difficult
- food sometimes goes in the wrong direction
- food lasts longer or is more tiring
- there is a risk of aspiration (food in the lungs)
ResearchediPositive results in clinical studies, not yet standard treatment
Recent research shows that evaluation of swallowing and chewing ability is important, especially in children with SMA types 1 and 2 under treatment. A speech therapist or food and drink specialist can investigate how eating and drinking are going and can provide appropriate strategies.
For some people, food consistency or drinking thickness are adjusted (thicker, ground, or liquid foods). A dietician or doctor can give advice about this.
Weight and body composition
**Supporting a healthy weight**
At SMA, a healthy weight is important. This helps:
- to make the heart and lungs work better
- to absorb food properly
- to support the muscles as much as possible
ResearchediPositive results in clinical studies, not yet standard treatment
Children with SMA types 1 and 2 who are being treated with disease-modifying therapies may have feeding problems. Regular monitoring of growth and weight development is often done as part of standard care. A dietician can help set a diet so that a healthy weight is reached and maintained.
Some children may have trouble getting enough energy and food intake. In that case, extra food may be necessary, for example energy-rich drinks or supplementary food.
Breathing and nutrition
**Breathing and nutrition are connected**
The muscles that are needed for breathing and swallowing work together. When respiratory muscles are weakened, nutrition can sometimes be more difficult — especially when someone is tired or has to make a lot of effort.
ResearchediPositive results in clinical studies, not yet standard treatment
In severe SMA, the ability to swallow and chew may be so limited that other ways of supplying food are necessary, for example food directly into the stomach via a feeding tube. This will be discussed with the team that is monitoring the disease.
Regular exercise and exercise (physical therapy) can help support the strength around eating and drinking.
Energy and protein
**Sufficient energy and protein are important**
The body at SMA needs nutrients to keep muscles healthy. This is even more true when muscles are weakened. Sufficient energy and protein help:
- keep the body resilient
- to combat muscle inflammation
- supporting the recovery and adaptation process
ResearchediPositive results in clinical studies, not yet standard treatment
For children with SMA who receive disease-modifying therapies, it is important to look at nutritional status and energy needs. The doctor and dietician follow this.
There is no evidence that special dietary schedules or strict regimens cure or worsen SMA. The starting point is a varied, nutritious meal with vegetables, fruits, whole grains, proteins and healthy fats.
Food and medications
**Interactions are possible**
Some medicines used for SMA may affect hunger, gastrointestinal movements, or food intake. This may mean that:
- you feel more or less hungry
- gastrointestinal problems occur
- certain nutrients are absorbed worse

Disease-modifying therapies for SMA may have consequences for diet and drinking. This is being monitored as part of healthcare.
It is important to discuss this with your doctor or dietician, so that nutrition can be adjusted where necessary.
Nutrition and vomiting or reflux
**Heartburn and food choices**
Some people with SMA experience reflux or heartburn, especially when muscles in the abdomen are weaker. This can make eating more difficult.
ResearchediPositive results in clinical studies, not yet standard treatment
In SMA, stomach and intestinal problems can occur. Regular small meals, avoiding too much fat or acid, and positioning can help.
A dietician can indicate which foods may be better tolerated.
Vitamins, minerals and supplementary products
**No evidence for special supplementation**
There is no scientific evidence that special vitamin supplements, herbs or food supplements improve or slow down SMA. Individual nutrients, minerals or powders also have no demonstrated effect.
UnproveniNo scientific evidence that it works
Many supplements are offered with the promise of helping SMA. None of this has been scientifically proven.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Certain supplements can interact with treatment or be harmful in high doses. It is important to always discuss this with your doctor or dietician before adding anything.
A normal, varied diet generally contains sufficient vitamins and minerals.
Drinking and fluid balance
**Drinking enough**
With SMA, your body, like any other body, may need sufficient water. Sometimes this is more difficult, for example because:
- drinking is difficult due to swallowing problems
- you move less and therefore perspire less
- breathing aids are used
ProveniIncluded in official guidelines, or approved by EMA or FDA
Adequate fluid intake is important for all body functions, also in SMA.
Drinking can be adapted (thickened, coloured, in small amounts) to make it easier.
Summary and contact with your healthcare provider
Nutrition is an important part of care in SMA. Each person and each phase of the disease can have different nutritional needs. A dietician and doctor familiar with SMA can work together with you to determine how nutrition can best be tailored to your situation, possible swallowing problems, medication and general well-being.
