Right-Sided Heart Failure Symptoms: What to Know

The right side of the heart moves blood towards the lungs. When its pumping function is reduced, pressure can build in the veins and fluid may collect in the legs, ankles, abdomen or tissues under the skin.

Swollen ankles or legs may become more noticeable later in the day or after standing. A tight waistband, reduced appetite or feeling full quickly can occur when fluid affects the abdomen. Fatigue may reflect reduced blood flow or the effort needed to carry extra fluid.

Right-sided failure can occur alongside left-sided heart failure, lung disease, heart rhythm problems or high blood pressure. A symptom alone cannot identify the cause. A clinician may check your heart and lungs, review medicines, measure blood pressure and arrange tests when needed.

Arrange a medical assessment if new swelling, breathlessness, fatigue or rapid fluid-related weight change is developing, especially if you already have heart or lung disease. Keep a note of when symptoms started, whether they vary during the day, and any changes in your medicines.

Take prescribed medicines as directed and do not change doses or stop treatment without advice. A chronic disease review can help monitor symptoms, blood pressure, kidney function and treatment response. Ask whether your clinician wants you to track weight or limit salt and fluids.

Seek emergency help for severe or rapidly worsening breathlessness, chest pressure or pain, fainting, new confusion, blue or grey lips, or an inability to speak in full sentences. Do not drive yourself if you feel faint or severely unwell.

Contact a healthcare professional promptly for quickly increasing swelling, breathlessness while resting, marked abdominal swelling, or a sudden decline in exercise ability. These changes may signal worsening fluid congestion and need timely review.

Ask: Could another condition or medicine be causing the swelling? What symptoms should I record at home? Which warning signs mean I should seek urgent help? Do I need tests to assess heart rhythm, heart pumping or fluid levels?
