The Gut-Brain Connection

Parkinson’s is often thought of as a movement disorder, but for many people, digestive issues like constipation or bloating can appear long before any changes in movement. These symptoms aren’t just side effects; they’re likely part of a much bigger picture.

That’s because your gut and brain are in constant communication through something called the gut-brain axis. This connection is so powerful that researchers believe a key protein involved in Parkinson’s (called alpha-synuclein) may actually begin building up in the gut years before it appears in the brain. So, supporting gut health isn’t just about improving digestion; it may also play a role in how Parkinson’s develops and progresses. 

Constipation is one of the most common (and frustrating) non-motor symptoms of Parkinson’s. It can be caused by changes in dopamine levels, shifts in the nervous system including the vagus nerve, and even certain medications. When digestion slows down, it can affect how well your medications are absorbed and may also contribute to abdominal discomfort, bloating, or a general sense of sluggishness that impacts your day-to-day energy. 

The good news? There are some simple ways to support digestion - starting with what’s on your plate.

One of the most important things you can do is increase fiber intake. Foods like oats, chia seeds, cooked vegetables, lentils, and fruits such as kiwi or prunes can all help keep things moving. If fiber isn’t something you’ve paid much attention to before, it’s a good idea to increase it gradually so your gut has time to adjust. And don’t forget to drink plenty of water to help fiber do its job effectively!

Speaking of hydration, staying well-hydrated is key. Most people need more fluids than they think and a warm drink in the morning (like herbal tea or warm water with lemon) can be a gentle way to help stimulate digestion and establish a routine.

Another helpful tool is incorporating naturally fermented foods. Yogurt or kefir with live cultures, a spoonful of sauerkraut or kimchi, or small portions of miso or tempeh are all great options. These foods naturally contain beneficial bacteria that can support a healthier gut environment without the need of supplements. 

And don’t underestimate the power of movement. Even a short daily walk can improve digestion and encourage regularity, especially when it becomes part of your routine.

Digestive issues are common in Parkinson’s, but they don’t have to be something you simply learn to live with. Small, consistent changes to your daily habits such as improving your diet, drinking enough water, and staying physically active can have a big impact on how you feel, how well your medications work, and your overall quality of life.
