5 Warning Signs Your High Blood Pressure Is Damaging Your Blood Vessels—Risk of Stroke, Heart Attack, and Kidney Failure

Dr. Jetsada Boonyavongvarodom, Deputy Director of Primary Care Services at Maha Sarakham Hospital, shared health information on his Facebook page "Dr. Jet" about high blood pressure, urging people to stop eating habits that damage nerves and spike blood sugar.

Many people have high blood pressure but live as if nothing is happening. The main problem is that most of them "don't feel pain"—that's the real issue. Many people think that simply taking medication to bring down the numbers is enough. But the truly frightening part is when high blood pressure quietly begins damaging "blood vessel walls" over time. Blood vessels don't rupture all at once; they gradually stiffen and become inflamed until one day they become a stroke, heart attack, or kidney failure before you even realize it. Today, I want you to watch for these 5 warning signs:

1. Morning headaches or frequent dizziness, especially after waking up. If you have mild headaches, dizziness, heaviness at the back of your head, or constant head tightness, be careful. Sometimes this is caused by high blood pressure during the night or early morning—the period when blood vessels face the most pressure. Many people take medication but never measure their pressure in the morning, so they don't know their blood pressure is still fluctuating.

2. Fatigue and getting winded easily. Walking a short distance makes you more breathless than before. Many people blame aging, but the truth is, if blood vessels start to harden, your heart has to pump harder. This causes you to tire more easily than normal. Some people get winded climbing just one flight of stairs, or their heart races abnormally when walking fast—things they used to do easily.

3. Blurry vision that comes and goes. Blood vessels in the retina are among the first to be affected by high blood pressure. If you have chronic high blood pressure, the tiny blood vessels in your eyes may begin to narrow or become fragile, causing blurry vision, unclear images, or eye pain. Some people only discover their blood pressure has been high for a long time when they get an eye exam.

4. Numbness in hands and feet, or extremities becoming cold easily. If blood circulation starts to decline, your hands and feet won't get enough blood. Some people start experiencing numbness easily, as if blood can't reach those areas, or their feet are cold all the time. This is especially risky if you also have high blood sugar or high cholesterol.

5. Declining kidney function or protein in urine without any symptoms. The kidneys are heavily damaged by high blood pressure because they contain many capillaries. With prolonged high blood pressure, your kidneys begin to filter poorly and may develop protein leakage. Many people's kidney function is already declining, but they feel no symptoms. So don't just look at blood pressure numbers alone—check your kidneys and blood vessels too.

Things that genuinely help reduce blood vessel damage from high blood pressure:

— Reduce salt, especially from processed foods, soups, and pickled items — Get enough sleep, as insufficient sleep causes blood pressure to fluctuate — Walk or exercise regularly to improve blood vessel elasticity — Reduce belly fat and lose weight to ease the burden on your heart and blood vessels — Increase omega-3s and foods with antioxidants to improve blood vessel elasticity — Add potassium from vegetables and fruits (if you don't have kidney disease) to balance sodium — Check your blood pressure regularly, especially in the morning—not just when you feel dizzy

Sometimes high blood pressure doesn't send a sharp, obvious pain signal. Instead, it gradually changes your body bit by bit—making you tire more easily, feel dizzy more often, and weaken your kidneys—until many people get used to these symptoms. I want you to understand that managing blood pressure isn't just about "numbers." It's about protecting your blood vessels, heart, brain, and kidneys in the long term. If you wait until symptoms become severe, your blood vessels may already be significantly damaged.
