What effect does fasting have on blood pressure?

Fasting is associated with several physiological changes in the body that can contribute to a decrease in blood pressure. During fasting, the body undergoes a shift in metabolism, utilizing stored energy reserves. This metabolic shift can lead to a reduction in insulin levels, which helps to improve insulin sensitivity.

Additionally, fasting may lead to a decrease in fluid retention and a reduction in sympathetic nervous system activity, both of which can contribute to lower blood pressure. As the body extends the fasting period, there might also be a decrease in systemic vascular resistance, which further supports the lowering of blood pressure.

While individual responses may vary, the general observation in many studies is that fasting tends to result in lower blood pressure readings in individuals who engage in this practice regularly. This makes the statement linking fasting to a decrease in blood pressure accurate, supporting the answer choice.

Understanding the complex relationship between lifestyle practices like fasting and cardiovascular health is crucial for those studying preclinical health fields, as it highlights the importance of diet and metabolic state in managing blood pressure and overall health.
