Just got a heads up from my wife's doctor that her blood pressure is too high. He told her to stop all caffeine intake. She only drinks one 36 gr cappuccino in the morning. Could she still have her morning cappuccino, if I switch her to decaf?

You're asking for medical advice on an on line forum? On your wife's behalf? Good luck with that.

Jim - I appreciate your perspective and I can understand where you might think I'm being cavalier - my word - with her health. Thank you. What I hadn't posted, was this was offered by her G.P. not a cardiologist. She's not at the point where she needs a specialist. IMHO - since this is such a large forum with a diverse readership, there maybe others that have found themselves in a similar position and can offer some perspective. For the time being, she and I both feel that it is prudent to follow her doctors advice, but not do so blindly.

Overall please follow advice of physician who is directly involved in care of your wife. There may be other factors you are not aware.

Here is some **general** information on caffeine and high blood pressure from a (consensus) well-respected healthcare system: Mayo Clinic
https://www.mayoclinic.org/diseases-con ... q-20058543

There are causes for high blood pressure and risk factors for high blood pressure. You will find this on search of mayoclinic.org

This is not advice, but Mayo clinic has Caffeine: How does it affect blood pressure?

It is very unlikely that a single cap would affect BP, even if caffeinated. I suggest getting a BP cuff and checking.

Scott - thanks. I think you are right about the single cap especially if it's decaf. Good suggestion on the BP cuff. Her doc also recommended it and we got one yesterday.

Ian - you got me thinking and I went and did a bit of investigating. Here are some numbers. They are broad and far from being scientific.

The average 8 oz /226mg cup of brewed coffee has between 90 - 100 mg of caffeine.

The average 1 oz /28.3 mg shot of espresso has between 40 - 50 mg of caffeine.

The average 1 oz /28.3 gm of decaf espresso has between 4-5 mg of caffeine.

There are some sources according to "Dr.Google" that for someone with high BP they scale back from four cups (400 mg of caffeine) to two cups or roughly 200 mg of caffeine per day.

There may be other factors that her doctor is considering, but it would seem that a 36 mg shot of decaf would make her daily intake negligible. For now, until she sees her doc in a few weeks, she will cut caffeine out entirely.

Be wary. My missus bought one. They can be fussy and anxiety drivers.

Also, I once had a tech say my blood pressure was 140. I told her she was incorrect and to please redo it. She refused. When the doc came in, I said either you retake my pressure or I'm leaving and getting a new GP. He did and in my agitated state is was 112/60. Always get a recheck on the other arm if it's outside your normal.

Corti R, Binggeli C, Sudano I, Spieker L, Hänseler E, Ruschitzka F, Chaplin WF, Lüscher TF, Noll G. Coffee acutely increases sympathetic nerve activity and blood pressure independently of caffeine content: role of habitual versus nonhabitual drinking. Circulation. 2002 Dec 3;106(23):2935-40. doi: 10.1161/01.cir.0000046228.97025.3a. PMID: 12460875.

This seems to be the most recent credible article I could find with a quick search. The authors suggest- Acutely, coffee and caffeine induced comparable increases in MSA and BP in nonhabitual coffee drinkers, whereas habitual coffee drinkers exhibited lack of BP increase despite MSA activation to coffee. Because decaffeinated coffee also increases BP and MSA in nonhabitual drinkers, ingredients other than caffeine must be responsible for cardiovascular activation.

Might be worth reading that whole article. If you are in the USA your doctor should be able to pull it up on UpToDate.
Kind regards,
