I had 4 small applications on abdomen a month ago and wondered can this have anything to do with sudden high blood pressure?

A sudden increase in blood pressure is not a common side effect one month post liposuction. A temporary increase in blood pressure may be noted after surgery due to increased pain and anxiety, but one month later is uncommon. I suggest following up with your surgeon and primary care physician to evaluate the underlying cause of your elevated BP. Best, Dr. Emer

Thank you for your question and I am sorry that your elevated BP has caused you to worry.  I would get in touch with your family practice or general medicine doctor to have another set of readings performed to see what your blood pressure reading is like.  If you have recently had surgery it is possible to have an elevated blood pressure from pain or discomfort which normalizes as your healing progresses.  Once your blood pressure is taking over a series of times a better determination as to the cause can be diagnosed.  Best wishes.
