There is now a substantial body of evidence that indicates that GH Replacement Therapy has a beneficial effect upon many parameters:

Body composition improves, lean mass increases, and fat mass decreases sgnificantly.

-Fasting lipid profile improves with reduction on total cholesterol, LDL while HDL increases.

-GHT improves endothelial function as well as the markers of inflammation

- Carotid IMT also demonstrates a significant improvement during therapy

-Insulin resistance is Increased

-There is no data demonstrating that GHT reduces cardiovascular mortality in hypopituitary adults

- In addition: cancer risk may be increased
