My Dad is 90 years old. He is currently taking shots to correct his prostrate problems through his neurologist. He has a horse shoe kidney. I stopped his glipizide weeks ago because it would lower his sugar level to the 40's in the morning and now he has 98 readings in the morning. However, his blood pressure was always floating high to normal. Recently, too high 200 over 98. He is taking two medicines for HBP. What could be causing pressure increases?
