“Liposuction for fat deposits on my back and abdomen (63, 5'2", 115 lbs)”

I'm 63, 5'2", 115 lbs., but due to fat deposits on my back and abdomen I had liposuction in May (as well as a BA).

I've had essential hypertension for 30 years, it's often been difficult to control, and I was taking several meds for it. In June I noticed my readings were lower than usual so I decreased my Felodipine. In July they were still low, so I dc'd it altogether. In September the readings were so low and I was so fatigued that I started cutting my Diovan HCT in half, and have recently made a slight decrease in my Metoprolol as well. My current B/P readings are below 120/80 most of the time. Is this a common occurrance following liposuction?
