We May Now Know The Key Mechanism That Causes IBS
Between 10-20 percent of the global population might be suffering from IBS. Researchers have discovered that a locally driven immune response against certain food particles can cause the activation of mast cells in the digestive tract, resulting in the release of histamine. Histamine is a hormone involved in the physiological regulation of the gut and could be the explanation behind the pain and discomfort experienced by those with IBS.

It was once argued that coelacanths were the closest relative to land-based vertebrates, but the sequencing of the lungfish genome has confirmed their position as the mid-way point between fish and tetrapods.
