What are gastric secretagogues?
A secretagogue is a substance that causes another substance to be secreted. One example is gastrin, which stimulates the H/K ATPase in the parietal cells (increased gastric acid production by the stomach). Pentagastrin, a synthetic gastrin, histamine, and acetylcholine are also gastric secretagogues.

Are growth hormone secretagogues safe?
Safety of growth hormone secretagogues Within the limits of the current literature, GHSs appear safe, with few of the studies cited in this review observing serious adverse events (AEs) with the use of GHRPs. However, safety data are limited because of the overall short durations and small sizes of most studies.
Are there alternatives to insulin?
People with type 2 diabetes can often manage their condition without insulin therapy. Alternative treatment options include lifestyle and dietary changes and non-insulin medications, such as metformin.
