4. Halo around the iris
Fat deposits may also be seen in the eye, as a grey ring around the outside of the iris, the coloured part of the eye. This so-called “arcus senilis”, starts at the top and bottom of the iris before progressing to form a complete ring. It doesn’t interfere with vision.
About 45% of people over the age of 40 have this fatty halo around their iris, rising to about 70% of people over the age of 60. The presence of this fatty ring has been shown to be associated with some of the risk factors for coronary heart disease.
5. Rotten gums and loose teeth
The state of your oral health can also be a good predictor of the state of your cardiovascular health. The mouth is full of bacteria, both good and bad. The “bad” bacteria can enter the bloodstream from the mouth and cause inflammation in the blood vessels, which can lead to cardiovascular disease.
Studies have shown that tooth loss and inflammed gums (periodontitis) are markers of heart disease.
6. Blue lips
Another health indicator from the mouth is the colour of your lips. The lips are usually red, but they can take on a bluish colour (cyanosis) in people with heart problems, due to the failure of the cardiovascular system to deliver oxygenated blood to tissues.
Of course, people also get blue lips if they are extremely cold or have been at a high altitude. In this case, blue lips are probably just due to a temporary lack of oxygen and will resolve quite quickly.
In fact, the other five symptoms – mentioned above – can also have a benign cause. But if you are worried or in doubt, you should contact your GP or other healthcare professional for an expert opinion.
