Does fasting cause blood pressure to rise or increase? If I dont eat before Blood pressure reading measurement

Fasting can cause blood pressure to rise temporarily, especially during the first few days of the fast. This is because when a person fasts, their body experiences changes in hormone levels, which can lead to an increase in blood pressure.
During a fast, the body activates its stress response system, which increases the release of hormones like adrenaline and cortisol. These hormones can cause the blood vessels to constrict, which in turn increases blood pressure.

However, in the long term, fasting can actually have a positive effect on blood pressure. Some studies have found that periodic fasting may help lower blood pressure over time, as it can lead to weight loss, improved insulin sensitivity, and reduced inflammation, all of which can contribute to lower blood pressure.

It's important to note that fasting is not recommended for everyone, especially for people with pre-existing health conditions like high blood pressure. If you are considering fasting, it's important to consult with a healthcare professional first to ensure that it is safe for you to do so.

If you have high blood pressure, it's important to monitor your blood pressure regularly, especially during a fast, and to make sure you are following any recommended medications or lifestyle changes to manage your blood pressure.
