Like some insight for my father. My father a 64yr
make sure the measurements are OK and consider a diuretic
when a patient asks me about his/hers blood pressure I always try to remind the correct way to measure it, so let me start with this:
- you should first make sure that all measurements are carried out when he's calm and sitting for 5-10 minutes (no pain, no psychological stress, etc)
- you should take at least two measurements. If there's considerable difference between the first and the subsequent measurements then you should discard the first as false. The second is usually lower than the first and the third might be even lower. I usually advise patients to measure their blood pressure three times (2-3 minutes interval between measurements) and only consider the mean value between the 2nd and the 3rd measurement.
- use an approved and working manometer (check it against another manometer)
If his blood pressures are indeed higher than normal (140/90) then you should consider the following:
- salt intake: you've mentioned that he's already restricted salt consumption but watch for hidden salt as well (like in snacks, cheese, too much bread, etc)
- watch his weight: don't let him become overweight or obese.
- encourage him to increase his physical activity.
- if none of the aforementioned measures work then adding a new drug might be necessary.
You can always try maximizing the dosages for his current regimen. For example, losartan can be increased to 100mg. It would probably be more effective to add a new drug though. Diuretics are excellent options for most patients. Hydrochlorothiazide for example can be started at a dosage of 12,5mg per day (in the morning) provided that his renal function is OK and he has not experienced serious side effects from similar drugs in the past (like severe hypokalemia).
If he was stable for a long time and has only recently developed uncontrolled hypertension then looking for a cause might be worthwhile. For example patients with atherosclerosis may develop renal artery stenosis which may present with new (or worsening of existing but stable) hypertension.
Remember to avoid trying any changes without previously consulting with the treating doctor.
Let me summarize the basic points of my answer as follows:
- make sure the measurements are credible
- institute the necessary lifestyle changes (if not already in place)
- consider either increasing the dosage of the current drugs or adding a new one
- discuss with your doctor about secondary hypertension
I hope I've answered your question in a helpful way. Please let me know if you need further assistance.
