Why is one side of the face weak after a stroke?

Sudden facial droop is a warning sign

A face that suddenly droops on one side can be a sign of stroke. This is an emergency.

If this happens suddenly, especially with weakness or slurred speech, call for emergency help at once. Time matters greatly.

This page is about the weeks after a stroke, once the person is under medical care, not the emergency itself.

Why the face is affected

A stroke can weaken the muscles on one side of the face. This can affect the smile, the eye, and eating or speaking.

It can be upsetting to see and hard for the person too. It does not mean recovery is impossible.

Recovery of facial movement varies, and it is guided by the medical team and the right therapists.

Which professionals guide recovery

Facial weakness after a stroke is usually guided by the doctor and, where needed, a speech and language therapist. They assess the face, speech and swallowing.

A physiotherapist focuses on the body, movement and daily function rather than the facial muscles themselves.

We will point you to the right professional and work alongside them so the whole person is supported.

How families can support

Patience helps most. Eating and speaking may be slower for a while, so give the person time.

Good positioning at meals and calm communication both help, and these connect to our wider work. Protecting the eye may matter if it does not close well, so follow the doctor’s advice.

If anything changes suddenly, treat it as urgent and seek medical help.

Patience through the early weeks

The early weeks after a stroke can be worrying when the face is affected. Small daily tasks like eating and speaking may take longer.

We encourage patience and a calm pace, both from the family and for the person. Rushing rarely helps and can add to the strain.

We support the wider recovery of movement and daily life, while the doctor and speech therapist guide the face and speech. Together, this gives the person steady, well rounded support at home.
