DEAR DR. ROACH: I am responding to a recent letter from a reader anxious about undergoing a colonoscopy. One of her concerns was a possible perforation requiring additional surgery and a temporary colostomy. You reassured her that the probability of such an occurrence was very low.
I have seen this fear often. No doubt, it comes from most ...Read more

DEAR DR. ROACH: I read your recent column regarding asymptomatic atrial fibrillation. How does this differ from having a heart murmur? I have had a murmur for about 25 years, though it was not fully diagnosed until three years ago during an unrelated emergency room visit. Until recently, the murmurs were getting worse. Other than limiting my ...Read more
DEAR DR. ROACH: Three years ago, I turned 60 and received my first dose of Shingrix. I had a highly unpleasant reaction, with fever and flulike symptoms. I did not return for the second dose until last week, so although I have had two doses, they are three years apart. Do I need to get another dose in a short window of my most recent vaccination...Read more
DEAR DR. ROACH: I have COPD, and my doctor explains that the trouble is that my lungs do not expel the full amount of the breath I take in. This prevents the full oxygen intake from my breath. My question is, Do commercial oxygen generators serve any purpose if the full amount of oxygen supplied by them cannot fully enter the lungs? -- J.H.
DR. ROACH WRITES: I have written many columns on COVID-19, which has become a major cause of death and disability in all of North America and the world. I have consistently recommended the available vaccines, and tried to identify their (modest) risks and (dramatic) effectiveness. Recently, I have received many letters so full of misinformation ...Read more
DEAR DR. ROACH: I am an 86-year-old woman, and my sister is 91. We are both in good health, with normal health issues for people our age. My question is that we both have contracts with crematory companies, but we also intend to be organ donors. Will they really use organs from people our age? We both have some health issues. How should we ...Read more
DEAR DR. ROACH: I am a 77-year-old woman. I have had problems with insomnia for at least 50 years, but it is much worse now. Some nights I don't sleep, and some nights I get maybe three or four hours. My primary doctor will prescribe only certain meds and will not prescribe meds I took in the past, like Dalmane or others. All he will prescribe ...Read more
DEAR DR. ROACH: I am interested in your perspective on intermittent fasting. I am in a walking group of seniors (all 65+ years). Six of us have been on this diet for six to eight weeks, and everyone has consistently lost a pound a week. There is a lot of debate about how it works. We are on an eight-hour eating window and 16 hours of fasting. ...Read more
DEAR DR. ROACH: Please help me understand the connection between the use of baby powder or talcum powder and ovarian cancer. I can't grasp how a product that is applied externally can migrate to the ovaries and cause cancer. -- K.M.

DEAR DR. ROACH: On Nov. 2, 2020, I had a total right hip replacement. The surgery was successful, and the incision has healed completely. X-rays on the day of the surgery are clear. However, X-rays in April this year show something the surgeon called heterotopic ossification. It feels as if there is something large growing inside my hip. How ...Read more
DEAR DR. ROACH: How is preventive medical care handled when an individual is traveling to a remote location? For example, I will be hiking this summer in a remote area with no medical care available (it would take three days to get to a doctor).

DEAR DR. ROACH: I am a healthy man in my late 40s. I was married for 18 years to my first sexual partner. Since my divorce three years ago, I have had two additional partners.

DEAR DR. ROACH: I ruptured my Achilles tendon playing basketball seven years ago at the age of 49. I was able to recover and continue playing. My question has to do with others who have suffered from this: Why do so many young people appear to tear their Achilles?

DEAR DR. ROACH: Can you comment on the lack of a test that truly demonstrates the effective level of immunity an individual has from receiving the COVID vaccine?
