Blood pressure going up on colon cleanse

My husband and I are on day 4 of a 7 day bowel cleanse. We are doing a fruit juice, vegetable juice fast. We are taking liquid Bentonite and pysillium husk powder 3 times a day. Plus we are doing a colonic irrigation once a day.
I'm a little worried because my husbands blood pressure keeps going up. He checks it every day. In the past it has been just a little above normal, now as of today he said it was 157/82 so I'm confused on why this is happening. Anybody got any ideas on this? Tweet
