Gastrointestinal Disorders: A Neurological Perspective

Gastrointestinal dysregulation

Hello, Doctor.
After binge eating in 2008, I experienced stomach bloating in the afternoon, loss of appetite, and underwent gastroscopy which showed no issues.
I tried traditional Chinese medicine for treatment but saw no improvement.
In 2009, I had chest pain and took anti-inflammatory medication that caused gastric mucosal damage and tested positive for Helicobacter pylori (I underwent gastroscopy twice).
After treatment, I developed severe diarrhea and switched to traditional Chinese medicine for 2.5 months, which alleviated the diarrhea but I still experienced abdominal bloating.
Recently, I returned to Western medicine and have been experiencing diarrhea again, primarily from noon until before dinner.
During this time, I also experienced abnormal sensations in my mouth and tongue while sleeping, involuntary movements in my hands and feet, muscle twitching, nightly nightmares, post-nasal drip after meals, and sciatica pain spreading from my chest to my back, along with anal discomfort.
I have no desire for anything, including sexual activity, and feel mentally fatigued.
An abdominal ultrasound, liver function tests, and stool tests for occult blood all returned normal.
I tend to be neurotic and perfectionistic, and I had many distressing issues in 2008.
Could this be a case of autonomic nervous system dysfunction affecting my gastrointestinal system and causing pain? Currently, my medication includes 0.50 mg of Amlodipine, 1.00 mg of Famotidine, 1.00 mg of K.B.T., and 10 mg of Inderal.
I take half the dosage of the Western medication, which initially worked well, but now I am experiencing afternoon diarrhea again.
I am unsure of what to do next and whether I should undergo further examinations.

Dr. Gao Chunde reply Neurology

The condition commonly referred to as autonomic nervous system dysfunction primarily indicates an imbalance between the sympathetic and parasympathetic nervous systems, particularly when the sympathetic nervous system is overactive.
Symptoms may include palpitations, diarrhea, tremors, and insomnia.
If internal medicine evaluations, including endocrine and gastroenterological examinations, are normal, consideration can be given to seeking help from a psychosomatic medicine specialist.
Treatment targeting autonomic nervous system imbalance caused by anxiety or emotional issues is likely to be beneficial.

More Info

Understanding gastrointestinal disorders, particularly when they intersect with neurological issues, can be quite complex. Your symptoms suggest a multifaceted problem that may involve both gastrointestinal and neurological components, particularly given your history of stress and anxiety.

Overview of Your Symptoms
You have reported a range of symptoms including abdominal bloating, loss of appetite, gastrointestinal discomfort, and neurological symptoms such as involuntary muscle movements and sleep disturbances. These symptoms can indeed be interconnected, especially in the context of autonomic nervous system (ANS) dysregulation, which can affect gastrointestinal motility and function.

Autonomic Nervous System and Gastrointestinal Disorders
The autonomic nervous system controls involuntary bodily functions, including digestion. Dysregulation of the ANS can lead to gastrointestinal disorders such as functional dyspepsia, irritable bowel syndrome (IBS), and even exacerbate conditions like gastroesophageal reflux disease (GERD). Stress and anxiety can significantly impact the ANS, leading to symptoms like bloating, altered bowel habits, and discomfort.

Medications and Their Effects
You mentioned being prescribed several medications, including famotidine, Inderal (propranolol), and others. Here’s a brief overview of these medications:
1. Famotidine: This is an H2 blocker that reduces stomach acid production. It can help alleviate symptoms related to acid reflux and gastritis but may not directly address motility issues.

2. Inderal (Propranolol): This is a beta-blocker often used to manage anxiety and physical symptoms associated with stress. It can help reduce the physical manifestations of anxiety, which may indirectly benefit gastrointestinal symptoms.

3. Other Medications: Depending on what "k.b.t." refers to, it may have specific effects on your symptoms. Always consult your physician or pharmacist for detailed information about any medication.

Side Effects and Concerns
You expressed concerns about the side effects of these medications, particularly regarding gastrointestinal disturbances like diarrhea. It’s important to note that while medications can help manage symptoms, they can also have side effects that may exacerbate gastrointestinal issues. For instance, some medications can alter gut motility, leading to diarrhea or constipation.

Recommendations
1. Consultation with Specialists: Given the complexity of your symptoms, it may be beneficial to consult both a gastroenterologist and a neurologist. A gastroenterologist can help address the gastrointestinal symptoms, while a neurologist can evaluate the neurological symptoms you are experiencing.

2. Dietary Adjustments: Consider keeping a food diary to identify any potential food triggers that may exacerbate your symptoms. A diet low in FODMAPs may help if you are experiencing IBS-like symptoms.

3. Stress Management: Since stress appears to be a significant factor in your symptoms, incorporating stress management techniques such as mindfulness, yoga, or cognitive-behavioral therapy (CBT) may be beneficial.

4. Regular Follow-ups: Regular follow-ups with your healthcare providers are essential to monitor your symptoms and adjust your treatment plan as necessary.

5. Further Testing: If your symptoms persist or worsen, further testing may be warranted to rule out other underlying conditions. This could include imaging studies, endoscopy, or specialized gastrointestinal motility tests.

Conclusion
Your situation highlights the intricate relationship between the gastrointestinal system and the nervous system. It is crucial to approach your treatment holistically, considering both physical and psychological aspects. By working closely with your healthcare providers and possibly adjusting your treatment plan, you can find a path toward relief and improved quality of life. Always communicate openly with your doctors about your symptoms and any concerns regarding your medications.
