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 40s 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?
Hello, Welcome and thanks for your query. Your decision to stop Glipizide was correct. The blood pressure is high and fluctuant due to multiple factors. His kidney function would be on the decline due to age, diabetes and a neuropathic bladder. This elevates blood pressure. Another factor is the rigidity of arteries which gives a high pulse pressure. Sometimes people require up to 4 medicines to control blood pressure. If you like I can review his medicines and give my opinion.
