This is Vital Information: Everything You’re Too Embarrassed to Ask Your Doctor from the Sunday Times Bestseller
The new taboo-busting book from the internet’s favourite doctor and Sunday Times bestselling author of This Book May Save Your Life.
'When you want to sort medical fact from medical fiction, Dr Karan is your man.' Dr Julie Smith, bestselling author of Why Has Nobody Told Me This Before
Have you ever
· How do I get rid of bad breath?
· Are my boobs normal?
· Should I be farting this much?
In This is Vital Information, Dr Karan dives into the weird and wonderful world of medical taboos and empowers readers with the information they need to live longer and happier lives. You
· Learn to love your haemorrhoids, the unsung heroes keeping your backdoor sealed, and your dignity intact.
· Turn your gut into a natural Ozempic factory with the power of fibre.
· Protect your hairline by putting down the snake oils, cutting stress, and scrubbing your scalp.
· Reboot your understanding of ADHD because half of what you’ve heard online is wrong.
The fact is, everyone has weird thoughts from time to time, a rash is often just a rash, and a mole is normally nothing to worry about. But occasionally these bodily malfunctions can indicate something more alarming, so we shouldn’t delay talking about them with a medical professional just so we don’t have to have an awkward conversation.
Dr Karan explains why we all need to start talking openly with our friends, family and – most importantly – our doctors.
Now, open up and say ‘ah’…
Praise for Dr

This book was such a refreshing read. Dr Karan has a brilliant way of taking genuinely serious topics about health, the body, and being human, and delivering them with humour, warmth, and zero condescension. I found myself laughing one minute and quietly reflecting the next.
What really stood out was how easy to digest everything felt. You never feel overwhelmed or lectured, even when the subject matter could easily tip that way. Instead, it’s broken down into bite-sized insights that actually stick — the kind of information you’ll randomly remember weeks later.
Beyond the medical knowledge (which is clearly sound and reassuring), there are some lovely nuggets of philosophy woven throughout — reminders about mortality, anxiety, curiosity, and not taking ourselves quite so seriously. It manages to be comforting without being patronising, informative without being dry.
Funny, thoughtful, and genuinely useful. A great reminder that learning about your body doesn’t have to be scary — and that a bit of humour goes a long way. Would absolutely recommend.

3.5. Interesting topics covered. A bit too heavy on the motivational speak and same thing said in 3 different sentences. Overall, enjoyed the content but not the presentation.
