Constipation is a common non-motor symptom of Parkinson’s disease (PD), and for many people it appears early and persists long term. It may even declare itself before movement symptoms. Because the autonomic nervous system controls involuntary processes, digestion and peristalsis are often the first casualties of autonomic dysfunction, which affects up to 80% of Parkinson’s patients. Constipation is further exacerbated by other factors:
Reduced Awareness
People with PD may not feel or respond to the urge to have a bowel movement as frequently.
Decreased activity
Less movement can reduce intestinal activity, leading to even slower motility
Dietary factors
Low fiber intake and inadequate hydration can make stools harder and more difficult to pass
Stress
Elevated cortisol and anxiety can worsen all PD symptoms, including digestive ones
Toilet posture
Body positioning affects how easily stool passes, and optimal positions for evacuation may be difficult to maintain
Constipation is more than an inconvenience. It can lead to bloating, abdominal discomfort, and reduced appetite. In some cases, it may interfere with how medications are absorbed or create intestinal blockages. Because it’s linked to autonomic dysfunction, constipation can also be a signal that broader regulatory systems in the body are affected, which should prompt evaluation from your care team. It’s not uncommon to discover new symptoms while investigating existing ones.
Strategies to Manage Constipation
As disruptive as it can be, constipation is usually manageable. A combination of lifestyle adjustments and medical support can significantly improve motility. Increasing fiber intake adds bulk to stool, with fruits, vegetables, whole grains, and bran standing out as the most effective options. Adequate hydration is equally important. Aiming for consistent fluid intake throughout the day helps keep stool soft and easier to pass, while establishing consistent times for meals and bathroom use can help regulate bowel patterns. Warm beverages in the morning may help activate the digestive system. Many individuals find that coffee is especially effective for stimulating bowel movements. Natural remedies like prune juice and senna tea are also popular. Probiotic-rich foods such as yogurt, sauerkraut, and kimchi may support overall gut health, aiding motility in a more indirect way.
Regular physical activity stimulates intestinal movement as well. Even low-impact activities like walking or stretching can be beneficial. Abdominal massage, performed in a circular motion following the path of the colon, encourages intestinal contractions when used in conjunction with exercise. And finally, while evacuating, try elevating your feet on a small stool to bring the knees above hip level and simulate a squatting position. This makes it easier for stool to pass.
When to Seek Medical Guidance
If constipation persists despite lifestyle changes and dietary adjustments, consult a healthcare provider. They can evaluate contributing factors, adjust medications if needed, and recommend appropriate treatments. Every person is different and there’s no one-size-fits-all remedy for constipation. It may take a little trial and error to find the best plan for you.
