Dr Jeremy London suffered a heart attack after ignoring three key signs
A heart surgeon has explained a sign that you shouldn’t ignore when it comes to your heart health.
If you’re going to take anyone’s advice over a major organ in your body that keeps everything up and running – it’ll be from someone who works to repair it every day.
Dr Jeremy London, who often shares his tips and tricks for living a more healthy life, was asked by his son about the biggest ‘red flag’ of a heart attack, to which he uttered a perhaps surprising answer.
As someone who has suffered a heart attack himself after ignoring key warning signs, he knows just how important it is to prevent the worst.
Prior to his own attack, the doctor was suffering from fatigue, low energy, what felt like heartburn and a sharp pain in his chest.

While all three aren’t good signs, he went on to tell his son in the social media video that feeling like you’re struggling for breath and having chest pains during times of exertion, are both things not to ignore.
He said if things get better with rest, and only flare when you’re say, working out, you need to have an ‘honest’ conversation with yourself about your lifestyle.
He explained: “What’s one piece of life-saving advice that could prevent someone from having a massive heart attack?”
Revealing he’s not talking about running ‘a marathon’, the doc said if you’re struggling when ‘taking out the trash’ or ‘going up a flight of stairs’, it’s your body trying to warn you about what’s looming ahead.
“Cause what’s happening is, with an important blockage, as you exert yourself, the heart muscle below is not getting enough oxygen and nutrients,” Dr London said, adding that when ‘you sit down, heart rate comes down, and the symptoms are received.’

While people may say this is part of ‘getting older’, the expert explains they are danger signs that the body is trying to communicate about your health.
He said in the YouTube video: “Now, most people just shrug this off as ‘I’m getting older’ or they scale their lifestyle.
“They park closer at the grocery store. They take the elevator. But these are warning signs.
“You need to have some intellectual honesty about what your body is telling you. And remember, denial is not a river in Egypt.”
According to the Mayo Clinic, signs of a heart attack can include:
- Chest pain (pressure, tightness, pain, squeezing or aching)
- Pain or discomfort that spreads (shoulder, arm, back, neck, jaw, teeth or upper belly)
- Cold sweat
- Fatigue
- Heartburn or indigestion
- Light-headedness or sudden dizziness
- Nausea
- Shortness of breath
If you have these symptoms, it’s important to seek help and advice.

A doctor has highlighted some common symptoms that people should never ignore and explained why they are reasons to go see your doctor.
Going to do your doctor isn’t most people’s way to spend a morning, it can be time consuming, scary and even costly.
However, doctors from all over the world are regularly telling people that putting off finding out what is going on with your body can be dangerous.
A UK National Health Service (NHS) doctor has now issued a warning on social media and highlighted three symptoms he would consider red flags.
Speaking in a new TikTok video, Dr Kukadia, who goes by Dr Sooj online, said: “Here are three red flag health symptoms that you should never ignore.

The doctor advised going to see your health care professional if you recognize having any of these symptoms
“Please make sure you go to a doctor and get checked out if you have any of the following.
“Number one, a change in the shape, size or color of a mole more often than not is usually benign, but it’s better to be safe than sorry and get checked out.”
In addition to this, the NHS says you should also go see a doctor if a mole is painful or itchy, you have a mole that is inflamed, bleeding or crusty, you have a new or unusual mark on your skin that has not gone away after a few weeks or if you have a dark area under a nail that has not been caused by an injury.”
The doctor continued by stating that unintentional weight loss was another red flag to be aware of.
Unintentional weight loss can be a symptom of a host of underlying conditions such as cancer, thyroid issues, diabetes, heart failure, gastrointestinal problems, infections, stress, or depression. It can also be linked to your current diet or any medication you are taking.
The NHS advises: “It’s important to see a GP as soon as possible if you have weight loss and other symptoms. The earlier the cause is found, the sooner it can be treated.”
Speaking on the third sign, Dr Sooj added: “And finally, number three – a persistent change in the way that you poop.
“So are you now more constipated? Are you having more diarrhea or more loose stools?
“Are you having blood in your stools? All of these can signify different conditions, but once again, we just need you to book an appointment with your doctor to rule out some of the more sinister causes of it
