16. Lightheadedness or Dizziness
Lightheadedness and dizziness are common in heart failure, especially when the heart cannot pump enough blood to the brain. Patients may describe it as feeling “off balance,” “unsteady,” or “as though the room is spinning.” It can be mild at first, but in some cases, dizziness can become severe and interfere with daily life.
This happens because poor circulation reduces oxygen supply to the brain. It may also be worsened by medications like diuretics (water pills), which can lower blood pressure. Sudden posture changes, like standing up quickly, often make the dizziness worse — this is called postural hypotension.
Take the example of Mrs. Tori, a 68-year-old retired teacher. She often felt dizzy when getting out of bed in the morning. Once, she nearly fell in the bathroom. Concerned, her daughter took her to the hospital. Tests showed her blood pressure was very low due to heart failure medications, and her heart was pumping weakly. With careful adjustment of her medicines, her dizziness reduced, and she avoided future falls.
Dizziness in heart failure is more than just an inconvenience — it can lead to accidents, falls, and injuries. Families should keep an eye on elderly patients, as they are especially at risk. If dizziness becomes frequent or severe, doctors should review the patient’s treatment plan to make sure the balance between controlling symptoms and maintaining circulation is right.
