Final answer:
A disease caused by the hyposecretion of the pancreas is diabetes mellitus, particularly type 1 diabetes, which requires insulin injections due to insufficient insulin production.
Step-by-step explanation:
The disease caused by hyposecretion of the pancreas is diabetes mellitus. In diabetes mellitus, particularly type 1 diabetes, the pancreas produces insufficient amounts of insulin due to the destruction of insulin-secreting cells by the body's immune system. Without adequate insulin, blood glucose levels rise, leading to symptoms like excessive thirst and urination. Type 1 diabetes requires careful monitoring of blood glucose levels and regular insulin injections to manage the condition.
