Does Insulin shot increase blood pressure.

@tlgmedical welcome to Mayo Clinic Connect. I’ve been diabetic for nearly 50 years and I’m on insulin. Insulin is a necessity for metabolism. Normal people produce their own insulin. Diabetics don’t produce it, don’t produce enough of it or have a resistance to what insulin they do produce. Insulin itself should not increase blood pressure. When a diabetic needs injectable insulin it is sometimes difficult to achieve the correct dose and may require quite a bit of adjusting to get to the appropriate blood sugar target. Too low or too high a blood sugar is very distressing to the body and could result in blood pressure changes. Learn as much as you can about Diabetes and your husband’s treatment. You will find that Diabetes affects all aspects of his health; also all aspects of his health will factor in to his control of the Diabetes. It is a two way street.

I'm making an assumption here that he is taking daily blood pressure readings at home and close to when he takes his daily insulin injection. I'm a Type 1 diabetic. Some people have "needle phobia" and knowing, seeing, and anticipating an injection can make one anxious. If that is case, take his blood pressure readings after he has taken his injection and his system has had a chance to settle down, may result in more accurate readings. And I agree with Cheryl that insulin alone should not affect blood pressure. IMHO
