Don't Ignore Swelling During the Day

Although the image focuses on nighttime symptoms, another important clue can occur during the daytime.

Persistent swelling in the:

Feet

Ankles

Lower legs

can sometimes occur when the body retains excess fluid.

Heart failure is one possible cause, but kidney disease, liver disease, venous insufficiency, medications, and other conditions can also cause edema.

A new or rapidly worsening pattern of swelling should be medically assessed.

Nighttime Symptoms Don't Automatically Mean Heart Failure

This is an important distinction.

Seeing a social-media post about heart symptoms can easily lead someone to believe that every nighttime sensation represents heart disease.

That isn't accurate.

For example, waking up with a racing heart can happen after a nightmare.

Shortness of breath can result from asthma.

Chest burning can be caused by acid reflux.

Fatigue can come from poor sleep.

Leg swelling can result from prolonged standing.

Symptoms need context.

A healthcare professional may need to consider your medical history, blood pressure, medications, physical examination, ECG, blood tests, echocardiogram, or other investigations depending on the symptoms.
