Myotonic dystrophy (MD) is distinguished by myotonic symptoms as well as gradual muscle weakening. The gastrointestinal system is frequently involved and can occur at any level. Problems may include delayed emptying of the stomach (postprandial fullness), difficulty swallowing, diarrhea, constipation, intestinal blockage, inflammation of the intestine (colitis), abdominal pain, nausea, vomiting. The digestive system is generally affected by muscular dystrophies, especially those that cause muscle damage with aging like MD. Symptoms include abnormal movements of the stomach, bowel, or both; delay in emptying the bladder (incontinence); decreased ability to digest food; malnutrition due to inability to chew food properly; weight loss. People with muscular dystrophies often require special diets to manage their digestion problems. Intestines are the organs responsible for breaking down and absorbing nutrients from the food we eat. In general, the more severe the muscle damage, the greater the risk of gastrointestinal complications. In conclusion, muscular dystrophies can affect the digestive system, usually causing problems with its function. These problems can be managed with special diets and medications.
