What is your total caloric intake in a single day? Eating the right things but not enough of them could be your problem. You can find plenty of sites searching for "how many calories per day" to find what you need to be eating to gain weight. http://caloriecount.about
.com/cc/calories-goal.php can tell you what you need to eat to reach your goal weight. I put in the weight and height you provided, guessed 35 years old, male based on your userid, and it provided the following assuming you wanted to weigh 150 lbs (once again, just guessing):
"You should consume about
2,302 calories a day to reach your goal weight of 150 lbs This is at a reasonable weight gain average of 1 lbs per week, which should be reached by February 08, 2010."
Unless you are bleeding a lot and/or having a lot of diarrhea and you have UC, you should be absorbing nutrients just fine as most of this is done in the small intestine.
