7 healthy traits linked to lower death risk but only 2% of people have all 7 - are you one of them?

People who meet the 7 healthy goals recommended by the American Heart Association are less likely to die of cardiovascular causes.

Here there are:

- not smoking
- moderate exercise at least 5 times a week
- untreated blood pressure under 120/80
- HbA1c under 5.7%
- total cholesterol under 200 mg/dL
- BMI less than 25
- a diet high in produce, fish, and whole grains, and low in sodium and sugary beverages

Less than 2% of people reached all 7 ideals.

Those who met 6-7 goals had reduced risks for all-cause mortality (hazard ratio, 0.49), compared with participants meeting zero or one goal.

Only 60% of the eligible U.S. population gets screened for colon cancer

Only 61% of the eligible population in the USA gets screened for this common cancer, according to The Lancet.

Here are some excerpts from the new guidance for colorectal cancer screening by the American College of Physicians (ACP):

- colorectal cancer screening should start at the age of 50 years for people at average risk, and at 40 years (or 10 years before the age of the youngest case of colorectal cancer in a family) for people at high risk

- stool-based tests, flexible sigmoidoscopy, and optical colonoscopy are all acceptable screening options for people at average risk

- the gold standard—optical colonoscopy—is recommended for people at high risk

- screening should be stopped for adults aged over 75 years or who have a life expectancy of less than 10 years

Colorectal cancer screening can lead to harmful outcomes such as perforation, bleeding, and false-negative results.

10 Questions You Need to Ask About Colonoscopy

From The NYTimes:

  1. Why is effective bowel preparation important?
  2. How can I maximize my chance of an effective bowel preparation?
  3. Are there certain medications I should stop taking before colonoscopy?
  4. Are all colonoscopists equally effective at finding polyps and cancers during colonoscopy?
  5. How can I be sure that my colonoscopist will do a careful examination?
  6. How can I reduce the risk of a complication during colonoscopy?
  7. Should I try colonoscopy without sedation?
  8. If I undergo sedation, should it be given by an anesthesiologist?
  9. Do all colonoscopists follow the same rules to determine when my colonoscopy should be repeated?
  10. Why aren’t the problems with the delivery of colonoscopy already solved?

Questions # 1, 2, 3, 6, 7 are very important, question # 10 probably not so much.

17% of U.S. hospitals now provide virtual colonoscopy


Medicare does not currently reimburse routine screening with virtual colonoscopy, but it does cover evaluations with "regular" colonoscopy.

Munchausen's syndrome - NHS video

From the NHS Choices YouTube channel: A psychiatrist explains the motivation behind Munchausen's syndrome, also known as factitious illness, where someone pretends to be ill or causes symptoms in themselves. This can include inflicting wounds or tampering with blood and urine samples. He also explains the importance of getting treatment and describes another form of the condition where a person fabricates an illness in someone in their care (Munchausen's syndrome by proxy):
