Studies on animals have produced similar good results.

One study conducted in Denmark involved rats with experimental colitis. The rats that received HGH treatments were observed to exhibit less damage - both at the macroscopic and microscopic levels - than did the control group. Further, these rats were able to come back to their original body weight after only 7 days of treatment. The control group, on the other hand, still weighed in at 11% below their original weight at the end of this period.

In other studies on animals, observations indicate that HGH has been able to promote healing on internal surgery as well. One study, in which lengthy segments of the digestive tract were surgically removed, showed that actual regeneration of the digestive tract had taken place after HGH treatments.

Also in this study, HGH was shown to increase the speed of recovery.

All of which suggests that for humans undergoing serious gastrointestinal surgery in the future, HGH may well be chosen to assist them in their recovery. Burn victims have shown the improvement expected with increased IGF-1 levels on experiments done in Japan recently.
