What To Do About High Diastolic Blood Pressure
If you're experiencing a significant increase in diastolic blood pressure — the lower number in a blood pressure reading — it's important to first rule out any secondary causes that may be responsible for the elevation. Conditions such as hyperthyroidism, hormone-secreting adrenal tumors, renal artery stenosis, or impaired kidney function can all lead to secondary hypertension.
Addressing Underlying Medical Conditions
When elevated diastolic pressure is linked to an underlying health issue, treating the root cause becomes the priority. For example, managing an overactive thyroid through medication, surgery, or radioactive iodine therapy can help bring blood pressure back to normal. Similarly, removing an adrenal tumor or addressing renal artery narrowing through angioplasty or surgery can significantly reduce blood pressure levels.
Treatment Options for Primary Hypertension
If tests confirm that the elevated diastolic pressure is due to primary (essential) hypertension, several medication classes can be effective in managing the condition. These include:
- Angiotensin-converting enzyme (ACE) inhibitors
- Angiotensin II receptor blockers (ARBs)
- Beta-blockers
Why These Medications Work Well for Diastolic Hypertension
These drug categories have been shown to specifically target and reduce elevated diastolic blood pressure more effectively than some other antihypertensive options. ACE inhibitors and ARBs work by relaxing blood vessels, which reduces strain on the cardiovascular system. Beta-blockers, on the other hand, lower heart rate and cardiac output, both of which can contribute to lower diastolic readings.
It's important to note that any medication regimen should be closely monitored by a healthcare professional to ensure optimal dosing and minimal side effects. Lifestyle modifications — such as reducing sodium intake, engaging in regular physical activity, and maintaining a healthy weight — should also be incorporated for comprehensive blood pressure management.
