Keloids are raised, thickened scars that form due to an overactive healing response. While they are often seen as a cosmetic issue, research suggests a strong connection between severe keloids and high blood pressure (hypertension).

How Does High Blood Pressure Affect Keloids?

A study from a Scar/Keloid Clinic found that patients with severe keloids—either very large or multiple keloids—were significantly more likely to have hypertension compared to those with smaller or fewer keloids.

Researchers believe this happens because high blood pressure increases mechanical tension on blood vessels and endothelial cells, the cells that line the inner walls of blood vessels. This extra stress may trigger an excessive scarring response, leading to larger, more stubborn keloids.

Can Managing Blood Pressure Help Reduce Keloids?

Since hypertension seems to make keloids worse, keeping your blood pressure in check could improve skin healing and reduce keloid severity. Possible ways to help include:

✅ Taking blood pressure medication if prescribed – Some anti-hypertensive drugs may also support better wound healing.
✅ Eating a heart-healthy diet – A diet rich in fruits, vegetables, and lean proteins can improve circulation and skin health.
✅ Staying hydrated – Proper hydration helps maintain healthy blood flow to the skin.
✅ Using early scar treatments – Silicone gel, pressure therapy, or laser treatments can help prevent keloids from growing.
✅ Consulting a specialist – A dermatologist can provide personalized treatment options, especially if you have both hypertension and keloids.

If you have high blood pressure and keloids, managing your blood pressure may help prevent keloids from getting worse. By improving vascular health, you may also reduce scarring and support better wound healing.

If you’re struggling with keloids, talk to a dermatologist and a doctor to create a treatment plan that works for your skin and overall health.
