I actually just finished the chapter on the digestive system in my A&P class, so I think I have an answer for you. No, you shouldn't have any nutritional deficiency problems.
Usually, water and electrolytes are the only things lost due to D. However, some B vitamins and vitamin K are absorbed in the colon, so if you are having lots of persistent D for long periods of time, maybe that could be a concern. Also, D can be caused by malabsorption in the small intestine (for example, celiac disease), so it might not be a bad idea to have your nutritional status evaluated anyway.
But usually, macronutrients are digested and asbsorbed by the time they reach the large intestine. Even though you are going all the time, unless food is coming out looking exactly like it did when it went in, I'm pretty sure that digestion & absorption has taken place. It is probably just the osmolality of your stool and increased motility that makes it seem like it is going right through you. But, then again, I am not a doctor. If you are concerned, you should talk to yours.
