Stomach bloating is a very real and common struggle for people with Parkinson's, and you're absolutely right that there's a gut-brain connection worth understanding.
Up to 80% of people with Parkinson's experience gastrointestinal (GI) symptoms. This happens because Parkinson's affects the autonomic nervous system, which controls the muscles in the digestive tract.
The gut-brain link works like this:
- An imbalance of gut bacteria (called gut dysbiosis) causes inflammation
- That inflammation damages the gut lining, allowing bacteria to "leak" into the bloodstream
- This triggers production of proteins that clump together in the brain, affecting dopamine levels Common GI symptoms tied to Parkinson's include:
- Bloating
- Constipation
- Nausea
- Gastroparesis (delayed stomach emptying), which can make you feel full very quickly
- Changes in bowel movements
Some Parkinson's medications can also contribute to bloating and constipation as side effects. Some MyParkinsonsTeam members have found probiotics helpful for GI symptoms like bloating and upset stomach, though results vary — some notice improvement, others aren't sure. Research does suggest probiotics may help with constipation and stool consistency.
It's worth bringing up your bloating with your neurologist or doctor, as there are dietary, lifestyle, and medication options that may help manage it.
