What happens to body during diarrhea? Especially the water part? Normaly, the water we drink is absorbed in the body and most part of thrown removing toxic elements via urine. But, during diarrhea body losses lot of water and we become dehydrated and weak. Suppose due to some process let’s say like Osmosis the water travels thru membrane and finally transforms into another substance, blood. So, during dehydration, does this process reverse? Why do we feel weakness? Also, when body knows it’s getting weak why it is still dehydration without absorbing any water? Someone please explain whole process.
In: Biology
Diarrhea occurs when colon is unable or unwilling to absorb the water in the fecal matter in the final stages of digestion to form solid fecal matter. Often this is because some water soluble toxin has accumulated in the fecal matter and/or the body doesn’t have enough time to extract the water from the fecal matter due premature bowel movement cause by something like gas. In extreme cases the toxic will reverse the standard process actually pulling more water into the fecal matter.
In fairly benign cases that uncollected water can just be substituted for by the consumption of extra water consumption so as to drive water absorption earlier in the digestion process. In more severe cases like cholera the reversal in normal colon function can deplete your blood’s electrolytes as well making it harder for your body to retain future water.
Depletion of water and electrolytes in the bloodstream makes it harder for your blood cells to move around and do their job in supplying your muscles and nerves the resources they need to do their jobs optimally. Which leads to a feeling of weakness as your muscles maybe less able to carry out physical tasks and your nerves are less able to communicate those tasks to them.
