# Nutrition in Myotonic Dystrophy
Myotonic dystrophy can have consequences for how your body processes and uses food. This tab describes what is known about nutrition, eating problems, and metabolism in this disease.
Swallowing and food intake
In myotonic dystrophy, the muscles involved in swallowing can become weakened or stiff. This can mean that eating or drinking becomes more difficult, or that food moves more slowly to the stomach. Some people notice that they take longer over a meal, or that certain nutrients are harder to swallow.
ResearchediPositive results in clinical studies, not yet standard treatment
Recent research has shown that the smooth muscles in the digestive tract can function differently in myotonic dystrophy, which can lead to disrupted food movement. This can result in discomfort, bloating, or other digestive complaints.
When eating and drinking become very difficult, a nutrition specialist or gastroenterologist can help suggest practical adjustments, or in rare cases, discuss other ways of feeding.
Food choices and muscle metabolism
There is interest in how certain nutrients can influence the energy metabolism of muscles. Research suggests that metabolism (energy conversion) in muscles in myotonic dystrophy can proceed differently, especially regarding how fat and energy burning take place.
ExperimentaliOngoing in study setting, outcome still unknown
Studies in animal models examine the role of fatty acids (such as oleic acid) and amino acids (such as leucine and methionine) in supporting muscle function. This research has not yet led to practical nutrition guidelines for patients.
For normal, everyday nutrition, it is not yet clear which specific eating patterns or products are best. A dietitian can help you eat healthily and nutritiously, tailored to what *you* can process well.
Nutritional deficiencies and absorption
Due to muscle weakness or stiffness, and because food moves more slowly, some people may not absorb nutrients as well. This can lead to weight loss or deficiencies.
ResearchediPositive results in clinical studies, not yet standard treatment
Poor food absorption can contribute to fatigue and weakness. Regular monitoring of weight and, if necessary, blood values helps keep track of this.
A nutrition advisor can help to:
- Prepare calorie-rich meals (for example, with oil, nuts, or dairy).
- Take nutrition in smaller portions and more frequently per day.
- Prepare soft or liquid food, if this is easier.
Medicines and nutrition
Some medicines used for myotonic dystrophy can affect nutrition, or nutrition can affect medicines.
ResearchediPositive results in clinical studies, not yet standard treatment
This differs greatly depending on the medicine. A pharmacist or doctor can explain which foods or drinks you can or cannot combine well with certain medicines. It is always worth asking about this.
Pregnancy and nutrition
For pregnant women with myotonic dystrophy, there are additional points of attention. Research reports that pregnancy can sometimes lead to increased muscle symptoms and increased muscle enzymes in the blood. This can mean that nutritional needs are different.
ResearchediPositive results in clinical studies, not yet standard treatment
Pregnant women with myotonic dystrophy need extra guidance from their treatment team and a dietitian. This is not the same as standard pregnancy care.
Gastrointestinal problems and nutrition
Myotonic dystrophy can affect both food movement (motility) and muscle function in the intestines. This can lead to constipation, diarrhea, bloating, or pain.
ResearchediPositive results in clinical studies, not yet standard treatment
A multidisciplinary team (gastroenterologist, dietitian, physiotherapist) increasingly works together to map out these problems and find practical solutions. This is an active area of research.
Possible adjustments may include:
- Food that is easier to process.
- Sufficient intake of dietary fiber (although this can also cause problems if motility is really disrupted).
- Regular fluid intake and physical activity.
Weight management
Some people with myotonic dystrophy have difficulty losing weight due to weakness and reduced activity. Others experience weight gain.
ResearchediPositive results in clinical studies, not yet standard treatment
Weight loss can worsen muscle weakness, so crash diets are unwise. Weight gain can put extra strain on muscles. Finding the balance is individual and requires guidance.
A dietitian and movement therapist can work together to look at sustainable, careful adjustments.
Supplements and vitamins
UnproveniNo scientific evidence that it works
There is no clear evidence that certain vitamins or supplements can prevent or improve myotonic dystrophy.
However, it is important to detect and address deficiencies (for example iron, B12, vitamin D) in time, especially if your food is not being absorbed well. Do this in consultation with your doctor or dietitian, not on your own.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Using many supplements on your own without supervision can be harmful, especially because some substances can interfere with medications.
Practical tips
- Make sure meals are not too large; eat smaller portions more frequently.
- Take time to eat; rushing increases the risk of swallowing problems.
- Ensure adequate fluid intake (unless you have swallowing problems; then water can be thickened).
- Regularly discuss your eating pattern and weight with your doctor or dietitian.
- Have your nutritional intake checked if your weight changes unexpectedly.
