Women are more prone to gastrointestinal disorders than men
Women are more prone to gastrointestinal disorders than men.Penn State Hershey College of Medicine\'s Tanja Babic found that the nerve cells that control the movement of food through the intestines are more sluggish in response to brain inputs in women than in men.
A team of researchers has revealed the reason behind women being afflicted with gastrointestinal (GI) disorders more often than men.Men and women handle the condition differently, "toughing it out" versus getting it checked out. Studies suggest that the GI system behaves differently in women because of sex-related features in the brain.

Penn State Hershey College of Medicine's Tanja Babic found that the nerve cells that control the movement of food through the intestines are more sluggish in response to brain inputs in women than in men. Babic said that females also show differences in brain structure and function compared to males, including higher levels of GABA (gamma-aminobutyric acid), an inhibitory neurotransmitter.
Babic noted that if they can selectively change the activity of these neurons in females, they would have a potential therapeutic target for better treatment of GI disorders in women.To identify these differences, Babic measured the type of nerve signal received from the brain and the nerves' responsiveness to the signals in rats. She found that the nerves in female rats received more signals that suppress the intestinal movement of food.
The nerves were also less responsive when stimulated. According to Babic, the data support that the nerves controlling the intestines in females are less excitable and receive more inhibitory signals from the brain, offering one explanation of why digestion problems are more common in women.The aim of this study was to investigate sex differences in the basic properties and GABAergic inputs to gastric-projecting DMV neurons.
