Why overly aggressive blood sugar and blood pressure treatment can be risky for frail seniors

For frail older adults, especially those with multiple health conditions, lower blood sugar and lower blood pressure are not automatically better.

Two physicians caution that driving these measures too far down can do more harm than good. They argue that care should prioritize safety and quality of life rather than rigid numerical targets.

The article appeared in the Journal of the American Geriatrics Society and was authored by Joseph Ouslander of Florida Atlantic University and Michael Wasserman of the California Association of Long-Term Care Medicine.

Rather than presenting new trial data, the authors examined prior research and used it to outline recommendations for better care.

Diabetes and high blood pressure are common in older adults, and treating them can reduce the risk of serious complications such as heart disease and stroke.

Even so, medications can sometimes push blood sugar or blood pressure too low.

Very low blood sugar may lead to weakness, confusion, sweating, or loss of consciousness. Blood pressure that drops too far can cause dizziness, fainting, and falls.

These outcomes can be especially dangerous for frail seniors, including nursing home residents and people living with dementia or other severe illnesses.

A fall can result in broken bones or a hospital stay, and severe hypoglycemia can become a medical emergency.

The experts say treatment goals should take into account a patient’s overall health, ability to function day to day, and personal preferences.

For some older adults, tighter control may still offer benefits. For others, the potential harms may outweigh the advantages.

The authors also noted that several major blood-pressure studies included relatively few frail nursing home residents or people with serious illness, making it difficult to apply the same targets to everyone.

They recommend using medical records to spot episodes of dangerously low blood sugar or blood pressure, then reviewing whether medications played a role.

They also call for better care plans, more research that includes frail older adults, and quality measures that account for the risks of overtreatment.

Their message is not to stop treating diabetes or high blood pressure. Instead, treatment should be tailored to each individual.

For frail older people, avoiding falls, emergencies, and unnecessary hospital visits may matter just as much as hitting a specific lab or blood-pressure number.
