More than 40% of Greater Lowell residents have high blood pressure, according to the 2025 Greater Lowell Community Health Needs Assessment cited by Lowell General Hospital cardiology chief Dr. Kirk Macnaught.
Macnaught said hypertension is a “silent killer” because most patients feel no symptoms until severe elevation, allowing untreated cases to raise risks of stroke, heart attack, kidney failure and blindness.
Massachusetts averages about 30% and the U.S. nearly 50%, placing Lowell above the state rate but in line with broader national and urban chronic-disease patterns.
Only about 20% to 25% of hypertensive patients nationally have their condition well controlled, he said, making yearly checkups important to keep readings below 130/80 and adjust treatment.
Three steps he highlighted were cutting sodium to 1,500-2,000 milligrams a day, losing even 5 pounds, and walking about an hour daily to improve blood-pressure control.
