What Is Preventive Health?
Preventive health means catching problems before they catch you. It refers to the steps you take before to stop illnesses before they show up.
Things like checkups, screenings that find issues early, vaccines that prevent illness, and habits that keep your body working well.
The Shocking truth
Only a very small percent, about 8% of people get all the preventive care they need.
That means 92% are skipping screenings, avoiding checkups, or just don’t know what they should be doing.
Here’s why that’s a problem: Half of all deaths are from things we could have prevented like smoking, eating unhealthy foods, not working out, not getting screened for cancer.
You can be in the 8%. And we’ll tell you how.
Why Prevention Actually Saves Money
Most people think they can’t afford preventive care, but the truth is you can’t afford to NOT do it.
Look at this situation for a moment.
Imagine your water heater starts making a weird noise. You ca do two things.
Either pay £80 for a plumber to check it now.
Or pay £3,000 when it floods your house next month.
It’s kind of the same thing with healthcare
Recent NHS data shows for every £1 spent on prevention, we get £8 back.
Some programs do even better.
Making homes safer for elderly people like fixing loose rugs, and adding railings. That’s £34 back for every £1, because treating falls is expensive.
Also, helping people quit smoking can be around £7-£10 back per £1. Even workplace mental health support can get £4.70 back per £1 and fewer sick days.
Right now, 75,000 people die every year in England from preventable causes. Not rare diseases. Things like smoking, ignoring high blood pressure, and not getting cancer screenings.
What This Means for You
Blood pressure check
1 . It actually costs nothing. You can check it for free at pharmacy, and it takes 2 minutes.
2 . It catches high blood pressure before you have a stroke.
3 . Saves: You could save £40,000-£120,000 in hospital bills, months of rehab, maybe your ability to walk.
Colonoscopy at 50
It doesn’t cost you money, as NHS covers it.
It catches polyps before they turn into cancer.
Saves £80,000+ in cancer treatment, and your life
Annual checkup
Costs you £0 as NHS covers it.
Can catch diabetes early while it’s manageable
Saves £4,000-£8,000 every year
Quitting smoking
It also doesn’t cost anything and you would be able to save at least £1,600 that you spend on cigarettes every year + cancer treatment.
And you’ll probably live 10 years longer.
Mammogram at 50
It also cost £0 (NHS)
Catches breast cancer when it’s tiny (Stage 1)
Also saves your breast, chemotherapy, possibly your life
Are you starting to notice the pattern? It’s basically shows that pay nothing now, and could save thousands later.
Sometimes save your life.
What Happens If You Don’t Practice preventive health?
When you don’t practice preventive health, you’re gambling that is going to go wrong.
And if it turns out that way, some awful things can happen, such as:
- Stroke you didn’t see coming: Months in hospital, and you can’t use your left arm anymore
- Colon cancer found at Stage 4 instead of as a removable polyp: Surgery, chemo, colostomy bag, 30% chance you’ll live 5 years.
- Diabetes caught too late: Daily insulin injections, going blind, losing your foot
That’s not even counting the money. That’s just what happens to your body.
The 4 Types of ways to practice preventive health
There are simple ways you can practice preventive health. Doctors talk about 4 ways. However, you don’t need to memorize this, but it can help you understand where you can step in.
1: Stop Bad Stuff From Starting
This is about your environment while growing up.
If you grew up in a smoke-free home, you’re way less likely to smoke. Also if your parents cooked vegetables, you
probably eat better.
What you can do: If you have kids, this is where your focus should be.
- Don’t smoke around them
- Keep healthy food in the house
- Make exercise normal
2: Build Good Habits Now
This is the big one for most adults.
It’s so much better, and helpful if you start eating vegetables to prevent heart disease. Exercise to prevent diabetes. And not smoke to prevent lung cancer.
This is where you have the most control in. The habits you build today, can play a huge factor in your health in 20 years.
3: Find Problems Early
Go for screening tests, as it can help
in finding disease before you feel sick.
Get colonoscopy to find polyps before they’re cancer. Also, a mammogram to find breast cancer when it’s tiny. Then blood pressure check to catch hypertension before stroke.
This saves lives. Early detection is the difference between “we removed it” and “it’s everywhere”
4: Manage What You Already Have
If you have a chronic disease, this prevents it from getting worse.
- A diabetic person should continue taking insulin to prevent blindness.
- Heart attack survivor should keep taking blood thinners to prevent a second heart attack.
If you’re here, stick to your treatment plan. It’s the difference between managing a condition, and being disabled by it.
Questions You Might Have
What’s the difference between preventive care and regular care?
Preventive care finds problems before you feel sick. Regular care treats you after you’re already sick. One catches things early. The other comes to fix things that may have gone wrong.
How often should I see a GP if I feel fine?
Once a year for a checkup. Do blood pressure, cholesterol, diabetes check. Have discussion about age-appropriate cancer screening. Then between visits, get your blood pressure checked at least every 2 years.
What screenings do I need in my 50s?
Everything from your 40s get a colonoscopy, mammogram, blood pressure, diabetes, plus bowel cancer screening kit every 2 years. Also, shingles vaccine at 50, and lung cancer screening if you’re a heavy smoker or used to be.
Can I actually prevent cancer?
Not all of it, but you can lower your risk significantly. Don’t smoke, as it can prevent lung cancer. Also limiting alcohol may help reduce liver, breast, and colon cancer. Exercising regularly and eating your vegetables can also lower colon cancer risk. Get screened helps in finding things early when it’s curable. About 40% of cancers are linked to things you can control.
Why colonoscopy at 45 if I feel fine?
Colon cancer grows slowly from polyps over 10-15 years. Colonoscopy finds, and removes polyps before they turn into cancer. By the time you have symptoms (blood, pain), the cancer is usually advanced. The screening age has dropped from 50 to 45, because the rates are rising in younger people.
Does this actually make you live longer?
It actually can help you live longer. People who get preventive care live 7-10 years longer on average. Not smoking adds 10 years. Controlling your blood pressure prevents stroke. Early cancer detection dramatically improves your chances of survival.
What if my GP says I don’t need something yet?
Guidelines can change based on research. If you have risk factors like your family history, obesity, or smoking, you might need earlier screening. Ask why. And if you’re still concerned, you can ask for it anyway or get a second opinion.
What’s the single most important thing?
Depends on your age and any risk factors you might have. But not smoking or quitting is a very important part of taking care of yourself. It can help prevent lung cancer, heart disease, stroke, and may even add 10 years to your life. Also, getting your blood pressure checked, and following the screening recommendations for your age, is good too.
