Summary
10 papers analyzed
Some studies suggest that blood pressure can be lowered within weeks using methods like acupuncture, breathing exercises, and certain medications, while other studies indicate that sustained reductions may require long-term treatments such as antihypertensive drugs, lifestyle interventions, and home telemonitoring.

How Long Does It Take to Lower Your Blood Pressure?
Lowering blood pressure (BP) is a critical goal for reducing the risk of cardiovascular diseases. Various methods, including pharmacological treatments, lifestyle changes, and alternative therapies, have been studied for their effectiveness and the time required to achieve significant BP reductions. This article synthesizes findings from multiple research studies to provide a comprehensive overview of how long it takes to lower blood pressure using different interventions.
Pharmacological Treatments for Blood Pressure Reduction
Antihypertensive Drugs
Pharmacological treatments are a common approach to managing high blood pressure. A meta-analysis of 52 large-scale randomized clinical trials found that antihypertensive drugs are effective in lowering BP, with the maximal effect observed after 12 months of treatment. The study showed that the BP-lowering effect gradually attenuates over the years, but significant reductions can be maintained for up to four years with appropriate treatment strategies.
SGLT-2 Inhibitors
In patients with diabetes and uncontrolled nocturnal hypertension, the SGLT-2 inhibitor empagliflozin significantly reduced nighttime systolic BP by 6.3 mmHg after 12 weeks of treatment. This reduction was greater than that observed with a placebo, indicating the efficacy of SGLT-2 inhibitors in lowering BP within a relatively short period.
Renal Denervation
Renal denervation (RDN) is another method that has shown long-term efficacy in reducing BP. A study on the ultrasound RDN technique demonstrated that patients experienced a significant reduction in office BP (OBP) by 18/11 mmHg from baseline to 36 months. This suggests that RDN can provide durable BP reductions over several years.
Lifestyle Interventions
Diet and Exercise
Lifestyle modifications, including dietary changes and exercise, are effective in lowering BP. The ENCORE study found that participants who followed the DASH diet combined with behavioral weight management experienced significant BP reductions that persisted for 36 weeks after the initial 16-week intervention. This indicates that lifestyle changes can have lasting effects on BP.
Breathing Exercises
Breathing exercises guided by interactive music (BIM) have also been shown to lower BP. In a study involving hypertensive patients, those who practiced slow and regular breathing for 10 minutes daily over eight weeks saw a significant reduction in clinic BP by 7.5/4.0 mmHg compared to the control group.
Alternative Therapies
Acupuncture
Acupuncture, a traditional Chinese medicine practice, has been investigated for its potential to lower BP. A randomized trial involving 160 outpatients with uncomplicated arterial hypertension found that a six-week course of active acupuncture significantly lowered mean 24-hour ambulatory systolic and diastolic BP by 5.4 mmHg and 3.0 mmHg, respectively. However, the BP levels returned to pretreatment values three to six months after the cessation of acupuncture treatment.
Inspiratory Muscle Strength Training (IMST)
Inspiratory muscle strength training (IMST) is a simple, time-efficient breathing exercise that has shown promise in reducing BP. A clinical trial protocol for IMST in middle-aged and older adults with obstructive sleep apnea (OSA) and above-normal BP aims to assess the long-term efficacy of this intervention over 24 weeks. Preliminary findings suggest that IMST can significantly lower casual systolic BP and improve cardiovascular health.
Conclusion
The time required to lower blood pressure varies depending on the intervention used. Pharmacological treatments can achieve significant BP reductions within 12 months, with effects lasting up to four years. Lifestyle changes, such as diet and exercise, can provide lasting BP reductions for several months. Alternative therapies like acupuncture and breathing exercises can also lower BP within weeks, although their effects may diminish over time. Overall, a combination of these approaches, tailored to individual needs, can effectively manage and sustain lower blood pressure levels.
