The hazards of insulin pumps may cause local inflammation and infection or abnormal fluctuations in blood sugar levels. If it is severe, it may lead to diabetic ketoacidosis.

1. Inflammation and infection: Insulin pumps are mainly used to treat diabetes. During the use of insulin pumps, the local care is relatively strict. If the local cleaning and care work is not done well during the use or installation process, it may lead to local inflammation and infection. It may cause symptoms such as redness, swelling, or pain of the skin, and it is necessary to have timely checks.

2. Blood sugar fluctuations: When using an insulin pump, it usually requires timely pressing of the button. If there is a situation of over-pressing during pressing, it may cause problems with the dose of insulin release, which may lead to fluctuations in blood sugar levels. Therefore, it is not recommended for elderly with dementia or those with consciousness disorders to use it.

3. Diabetic ketoacidosis: When using an insulin pump, there is generally a tube buried in the subcutaneous tissue. If the tube is too long during the burial process or if there is a tangle, it may cause the insulin not to be released into the body, which is dangerous for diabetic patients and may lead to diabetic ketoacidosis.
