Renin Angiotensin System - #17909

The renin-angiotensin system (RAS) plays a crucial role in regulating blood pressure and fluid balance in the body. When blood pressure drops, the kidneys release renin, which triggers a cascade that leads to the production of angiotensin II. This hormone causes blood vessels to constrict and signals the kidneys to retain sodium and water, which increases blood volume and raises blood pressure. While the RAS is activated primarily in response to low blood pressure, it is continuously active at low levels to maintain baseline pressure. Overactivation of the system, often seen in hypertension, can contribute to high blood pressure and kidney problems. Ayurveda offers several remedies for regulating blood pressure and supporting kidney health. Herbs like Arjuna and Punarnava are traditionally used to support heart and kidney function, and they may help in managing hypertension by balancing fluid and circulation. Diet plays a vital role in RAS regulation; Ayurvedic foods such as those rich in potassium (like bananas and leafy greens) and foods that promote detoxification can help balance blood pressure. Ayurveda also suggests Panchakarma, detox methods, and practices like yoga and breathing techniques to stabilize circulation and support kidney function. The time for Ayurvedic treatments to show improvement varies, but consistent lifestyle modifications and herbal remedies can help regulate blood pressure and support kidney function naturally over time.

The renin-angiotensin system (RAS) is a crucial mechanism in the body that regulates blood pressure and fluid balance. When blood pressure drops or sodium levels are low, the kidneys release renin, which triggers a series of reactions that convert angiotensinogen (from the liver) into angiotensin I and then into angiotensin II with the help of an enzyme called ACE (angiotensin-converting enzyme). Angiotensin II is a potent vasoconstrictor, meaning it narrows blood vessels to increase blood pressure. It also stimulates the release of aldosterone from the adrenal glands, which promotes sodium and water retention, helping restore blood volume. While RAS is most active during low blood pressure, it functions continuously to maintain stable circulation. However, if it becomes overactive, it can contribute to hypertension (high blood pressure) and kidney issues. In Ayurveda, balancing the RAS system involves supporting kidney function, improving circulation, and reducing excess water retention. Herbs like Arjuna (Terminalia arjuna) strengthen the heart and blood vessels, while Punarnava (Boerhavia diffusa) acts as a diuretic, helping regulate fluid balance and kidney function. Other herbs like Gokshura (Tribulus terrestris) and Dashmool (a combination of ten roots) support renal and cardiovascular health, potentially helping manage hypertension caused by RAS dysfunction. Ayurvedic detox therapies like Panchakarma can help remove toxins (Ama) that may contribute to inflammation and blood pressure imbalances. Diet plays a major role in regulating blood pressure and RAS activity. Ayurveda recommends potassium-rich foods like bananas, coconut water, and leafy greens, which counteract sodium retention and support kidney function. Avoiding excess salt, processed foods, and heavy meats can help prevent overactivation of the RAS. Hydrating well with herbal teas like coriander and fennel tea supports kidney health. Yoga, Pranayama (breathing exercises like Anulom Vilom), and meditation help reduce stress-related hypretension.
