Your body may also pull blood from the digestive system, causing nausea or vomiting. While these symptoms are easy to mistake for stomach issues, they become more serious when paired with chest discomfort or breathlessness.

6. Irregular heartbeat or palpitations

A fluttering or racing heart can mean the heart isn’t getting enough oxygen. This may disturb the heart’s rhythm, causing arrhythmias.

If these irregular beats persist or come with other symptoms like fatigue or pain, they should be assessed immediately.

Over time, this weakens the heart and damages vessels, leading to severe problems like strokes or heart attacks. The only way to detect it early is through regular checks.

8. Swollen legs or ankles
