Loss of sodium chloride through exessive sweat would cause

a) Edema
b) Diherria
c) Digestive problems
d) Reproductve problems






Answer is B. I guessed it correct but was wondering why Edema wouldn't be correct as well? I though that Edema can be caused by lack of reabsorbing liquid, thus losing ions like NaCl would lower the osmotic pressure and lower the amount of water reabsorbed into the body.

I was basically looking between A and B because I didn't find C and D to be related (if they are somehow, somebody please chime in). How I thought it through: Edema is excess fluid in the interstitium. If ion concentration went down, they're be nothing "pulling that water in." Diarrhea releases water from the body. Because the ion concentration went down, water would be released to maintain an osmotic balance like before.

Also, this is a side note, but is "edema" the official description of what's going on when pregnant women swell?

Well diarrhea is caused by a lack of reabsorption of water (says my lecture notes) in the LI, so I reasoned this question by the fact that there is no osmotic gradient for the water to be reabsorbed since there are no ions in the body...but I don't get how this is different from edema.

Edema is opposite -- a lot of water is reabsorbed into the tissues, causing the swelling associated with it.

right...so arn't they essentially the same thing? Your body isn't reabsorping the water from the stool because theres no osmotic pressure

Exactly, with diarrhea, your body isn't reabsorbing much.

Edema = LOTS of reabsorption of water (into the tissues) = LITTLE water out
Diarrhea = LITTLE reabsorportions of water = LOTS of water out

(Very oversimplified, but the general picture).
