Suggest Treatment For Severe Lethargy In A Diabetic Person
check the blood sugar at the earliest
I appreciate your concern regarding to your son in law.
You have to check the blood sugar, if it is within the normal ranges the pump is working and probably another cause should be tried to find out.
If the blood sugar results high you need to check the ketones in urine, if they are positive you need medical help.
Hope the information will be helpful. Please let me know if you've any further queries.
