The health headlines move fast and most coverage gets the science wrong. Every day, Dr. Ravi Kumar, MD, a board-certified neurosurgeon, cuts through the noise: what a new study or story actually says, what it doesn’t, and what it means for you. Researched, sourced, and reviewed before it’s published.
A study of about 172 million person-years found that California's red flag law was followed by at most a small drop in suicide among handgun owners, and for a family living with someone in crisis the step with the clearest evidence behind it is moving the guns out of the house, not waiting on a court.
If you have had a heart attack, a stent, bypass surgery, or angina, a Cochrane review of 107 trials says structured exercise rehab lowers your odds of another heart attack, and newer home and app-based programs appear to work as well as going to a center.
A study of 75,455 US adults with type 2 diabetes found the kidney advantage showed up only in people who had protein in their urine, which is a result most people can get from a cheap urine test they may never have been offered.
An FDA study of 14.8 million Medicare seniors found RSV shots cut RSV hospital stays by about 82% and deaths by 85%, and if you are 75 or older, or 50 to 74 with a condition like heart or lung disease, and have never had one, this fall is the time to ask about it.
A study of more than 862,000 US adults with new neck pain or headache found no extra risk of a neck artery tear after a chiropractic neck adjustment, which gives people who use adjustments better numbers on a rare risk, but it does not prove adjustments are safe for everyone, and sudden, severe, one-sided neck pain or headache with dizziness, vision changes, or slurred speech still means the ER, not an adjustment.
The FDA is asking drugmakers for data that could lead to the first US testosterone product made for women, and if you use it or are thinking about it after menopause, the evidence supports only one use, low sexual desire, so that is the first thing to confirm with your doctor.
An Oxford study of 275,205 people with unexplained weight loss found that watching how routine blood results change over time can point to cancer better than a single abnormal result, so if you are losing weight without trying, it is fair to ask your doctor to look at the trend, not just today's flags.
A BMJ investigation says US health officials leaned on one flawed method to scan COVID vaccine injury reports, but myocarditis was still caught by other checks, so if you have a reaction after any shot this fall, report it yourself and weigh the known rare risks with your doctor.
In a European trial of 10,799 people who had high-risk polyps removed, waiting 5 years instead of 3 for the next colonoscopy produced no more colon cancer over 5 years, which gives you a fair question to ask your gastroenterologist but is not a reason to cancel a scheduled scope.
A new national survey analysis finds polypharmacy in older Americans nearly doubled in two decades, and the most useful response is a full medication review with your doctor, not stopping pills on your own.
A national study of 25,176 people with diabetes in England found 23.5% died within a year of a below-knee amputation, so if you or a family member has diabetes, check feet daily, get any sore that will not heal seen quickly, and ask whether circulation has been checked before any amputation decision.
A reanalysis of all eight major randomized mammogram trials finds results consistent with overdiagnosis below 5%, not the 30% to 50% often cited, so if fear of treating a harmless cancer has shaped your screening choices, it is worth raising with your doctor, though it says nothing new about how many lives screening saves.
