Final answer:
A disadvantage of intensive therapy for type 1 diabetes is a greater risk of severe hypoglycemia.
Step-by-step explanation:
A disadvantage of intensive therapy for type 1 diabetes is a greater risk of severe hypoglycemia. When a person with diabetes receives intensive therapy, such as multiple insulin injections or continuous glucose monitoring, they may experience episodes of hypoglycemia where their blood sugar levels drop too low. This can be dangerous and may require immediate treatment. Although intensive therapy can offer benefits in terms of blood sugar control, the increased risk of severe hypoglycemia is a potential drawback.
