Can drinking lots of water lower blood pressure?
Answered by 1 Apollo Doctors
Drinking water has role in blood pressure maintenance. When a person is dehydrated BP drops initially but later on kidneys reabsorbs more water rather than excreting in urine and vasopressin is released which constricts the blood vessels, both together can increase blood pressure. Hence, every person should drink at least 3 liters of water in a day to prevent dehydration and to maintain BP. One should also note that excess water intake should also be avoided which can put more stress on heart and cause fluid retention in the body.

Hydration and Blood Pressure:
- Drinking water supports kidney function and helps maintain blood volume, which can prevent dehydration-related blood pressure spikes.
-
Limitations:
- Water alone is unlikely to significantly lower high blood pressure. A comprehensive approach including diet, exercise, and possibly medication is essential.
-
Medical Advice:
- Follow your healthcare provider’s recommendations for managing high blood pressure. Water intake should complement, not replace, other strategies.
-
Potential Risks:
- Excessive water intake can lead to electrolyte imbalances. Moderation is important.
In summary, while staying hydrated is beneficial, it should be part of a broader blood pressure management plan. Consult a healthcare professional for personalized advice.
