"Good grief..." Men often suffer from loose stools while women are more prone to constipation. These differences are deeply connected to the mechanisms of serotonin and TRPV4 channels in the gut. Here, we uncover these mechanisms and provide effective solutions!

The Role of Serotonin
Research on rats shows that the spinal defecation center differs by sex. In males, dopamine and serotonin enhance colon activity, while in females, dopamine does not work, and GABA suppresses serotonin's activity, leading to constipation. Increasing serotonin through tryptophan, 5-HTP, and vitamin B6 can help women combat constipation. "This enemy is invisible but formidable!"
TRPV4 Channels and Constipation
What is TRPV4?
TRPV4 stands for "transient receptor potential vanilloid 4," a type of receptor that responds to various stimuli. It is known as an osmotic pressure-sensitive receptor. When extracellular fluid osmolarity decreases, TRPV4 activates, causing cell swelling and triggering the receptor.
TRPV4 and Constipation
Constant activation of TRPV4 can make the colon insensitive to stretching, potentially leading to constipation. However, research shows that culturing cells with butyrate can suppress TRPV4 increase. Improving gut flora with probiotics can be effective against constipation. "This enemy is still ongoing..."
Solutions and Improvements
Increasing Serotonin
Tryptophan: Consume foods rich in tryptophan (bananas, turkey, dairy products).
5-HTP: Use 5-HTP supplements to directly convert into serotonin.
Vitamin B6: Ensure adequate intake of vitamin B6 (fish, liver, whole grains).
Regulating TRPV4
Butyrate: Take probiotics that produce butyrate (like Miyairi-san) to balance gut flora and prevent excessive TRPV4 activation.
Dietary Fiber: Increase intake of dietary fiber (vegetables, fruits, whole grains) to maintain gut health.
Conclusion
Adjusting serotonin and TRPV4 channels can improve gut issues like constipation and loose stools. Use the right diet and supplements to enhance your gut health. "Good grief... but now we see a way to defy fate!"
