5. Rapid Weight Gain: An Unexpected Sign of a Heart in Distress
A symptom of chronic systolic heart failure that can often catch people by surprise is rapid weight gain. This weight gain is typically due to fluid accumulation in the body, often connected to the heart’s inability to pump blood efficiently.
In chronic systolic heart failure, as the heart’s pumping action falters, the kidneys respond by retaining more sodium and water to compensate for the decreased blood flow. This retention leads to an increase in body fluids, reflected as rapid weight gain on the scale.
This weight gain can be abrupt and significant, often occurring over days or weeks. Individuals may also notice swelling or puffiness in the abdomen, legs, ankles, and feet, corresponding with the weight gain. Clothing and shoes may feel tight, and there may be a noticeable loss of appetite.
While fluctuations in body weight can occur for various reasons, including dietary changes and hormonal imbalances, rapid weight gain associated with other symptoms discussed, such as swelling of the extremities or persistent cough, warrants immediate medical attention. (5)
