Over the summer in about a month i lost about 15 pds or more and ever since then i have been having frequent bowel movements, gas, bloating, gurgling and bubbling noises. could the rapid weight loss be the direct cause of my problems??

My entire life ( almost 56 years now ), I have suffered with a dry, large, clay - like stool. But over the last few months or so, all that has changed. My bowel movements are now much more frequent and are almost always soupy or mushy, sometimes even to the point of mild diarrhea. There is no blood, no abdominal pain, no loss of appetite, or loss of weight. As a matter of fact, I've even gained about 5 pounds over the last 4 months and feel otherwise healthy. In actuality, it's been quite a relief not to have to strain like crazy when I sit down on the pot. But at the same time, it concerns me somewhat. Any explanations? Qualfied medical folks only, please.
This has been going for months now without any other signs or symtoms.

I have diarrhea, and it has been killing me. I had it for about 6 days now. Is there any way to cure it, or home remedies?

My doctor thinks that I am suffering from some sort of malabsorption problem, as in food is moving through my system too quickly. I haven't lost any weight though. Sorry for the TMI but the malabsorption makes sense when you consider my bowel movements, but the absense of weight loss is kind of perplexing to me. Does this ever happen?
