The Digestive Disorders of Diabetic Neuropathy and Autonomic Gastrointestinal Neuropathy

Diabetic neuropathy is one of the most common yet often overlooked complications of diabetes. This condition affects microcirculation and leads to a disruption in the oxygen and nutrient supply to the nerves through damage to the blood vessels. It can affect any part of the nervous system, but most commonly, the pain-sensing nerves and the autonomic nervous system are affected. Deficiencies in glucose regulation, particularly inadequate carbohydrate intake, can contribute to the onset of symptoms.

The relationship between diabetic neuropathy and the digestive system

Diabetic neuropathy can cause the most common digestive disorders among diabetics. Research indicates that a significant portion of diabetics, especially those with type 2 diabetes, may experience damage to the autonomic nervous system. This damage can result in various digestive complaints, the severity of which depends on the degree of innervation of the affected organ.

Damage to the nerves of the stomach and intestines can lead to various problems, including delayed gastric emptying, digestive disorders, and even nausea. In addition to inadequate carbohydrate intake, factors such as obesity, reflux, or poor dietary habits can also contribute to the emergence of symptoms. Digestive disorders in diabetics not only reduce comfort but also complicate the stabilization of blood sugar levels.

Disorders of the autonomic nervous system affect not only digestion but also the functioning of other abdominal organs, such as the bladder and sexual functions. Often, these problems occur together, further complicating diagnosis and treatment.

Difficulty swallowing and stomach complaints

Difficulty swallowing can be one of the symptoms of diabetic neuropathy. The autonomic nervous system is responsible for transporting food from the esophagus to the stomach, which is based on the work of smooth muscle cells. If these cells are damaged, it can lead to swallowing problems, and involvement of the esophageal sphincter can cause more frequent heartburn. Acid reflux can trigger pain and other unpleasant sensations, such as the formation of ulcers.

Additionally, diabetics often experience stomach complaints due to delayed gastric emptying. This condition, known as gastroparesis, makes digestion more difficult and affects about half of the patients. Symptoms of gastroparesis include abdominal pain, bloating, nausea, and vomiting, which not only worsen the patients’ well-being but also complicate the stabilization of blood sugar levels.

Long-term gastroparesis can cause serious problems, such as nutrient deficiencies, and may result in wide fluctuations in patients’ blood sugar levels, leading to increased insulin needs. Nausea and vomiting can cyclically recur, further exacerbating the situation.

Constipation and diarrhea in diabetic neuropathy

Diabetic neuropathy also affects the functioning of the colon, which can lead to constipation, diarrhea, and fecal incontinence. These problems typically occur alternately and significantly impact patients’ quality of life. Diarrhea, which often occurs at night, can be severe and watery, lasting for days. Additionally, in the case of constipation, bowel movements can become difficult, causing further discomfort.

Fecal incontinence is particularly observed among older patients and is often attributed to weakness of the anal sphincter or reduced sensitivity of the rectal nerves. Approximately 60% of those suffering from diabetic neuropathy experience severe constipation, which can lead to perforation or fecal impaction.

A proper diet, adequate fluid intake, and regular exercise can help alleviate complaints. It is important to monitor symptoms and consult with a specialist to receive the best possible treatment for the gastrointestinal manifestations of diabetic neuropathy.
