Your gastrointestinal system is responsible for the digestion of the food you consume. The muscles within it contract in a coordinated way to push the food along your intestine, but in some cases the muscles can become too weak, strong or uncoordinated. Dr John Martin explains all you need to know about intestinal dysmotility, from causes and symptoms to treatment.

What is causes intestinal dysmotility?

Peristalsis is the coordinated contraction of muscles in the bowel wall that pushes food through the gut.

 

When peristalsis becomes disordered, it’s known as dysmotility and this means that the intestines do not contract in the normal, orderly way. This can be due to the contractions becoming too strong, too weak or uncoordinated.

 

All parts of the gut may be affected by dysmotility, but the oesophagus is most commonly affected. This is the part of your digestive system which passes food from the mouth to the stomach.

 

What are the common symptoms of intestinal dysmotility?

The symptoms of intestinal dysmotility are often determined by the part of the gut that is affected. There is a significant overlap between these symptoms and those of irritable bowel syndrome (IBS) and in both conditions, the symptoms may be long-lasting and significantly affect patients’ quality of life. The common symptoms of intestinal dysmotility are:

  • Abdominal bloating
  • Alteration in bowel habit, particularly constipation
  • Abdominal pain
  • Nausea or vomiting
  • Feeling full after eating only a small amount of food

 

What are common secondary causes of dysmotility?

The nerves and muscles that control the intestine are highly complex and we currently do not entirely understand how they work. In patients with intestinal dysmotility, we do know that there is no structural abnormality within the gut and no inflammation, but we do not understand what goes wrong to make the gut contract abnormally. In most cases, no cause is found for the problem, but there are some medical disorders that can cause problems with gut function. These include:

  • Diabetes
  • Use of some medications such as pain killers

 

· Other conditions such as Parkinson’s disease, spinal cord injury, systemic sclerosis

  • Radiation therapy
  • Previous gut surgery

 

What is the treatment of intestinal dysmotility?

The treatment of intestinal dysmotility is tailored to the individual patient and is directed specifically at reducing symptoms.

  • Diet - There are no foods that restore the functioning and contraction of gut muscles. Often a dietician will help to identify any foods that may trigger symptoms and advise how to avoid these, but still maintain a healthy diet. In other cases, certain diets, such as a low FODMAP diet, can help ease symptoms.
  • Laxatives – these can be helpful in treating constipation
  • Motility agents – these are often used to try and reverse the intestinal dysmotility directly
  • Anti-sickness medications – these can be used to treat nausea and vomiting
  • Antidepressant medications – there is a high incidence of anxiety and depression in patients with symptoms of intestinal dysmotility and these drugs can help with symptoms, even in the absence of low mood or anxiety
