9. Ascites

Ascites, the accumulation of fluid in the abdomen, can be a symptom of heart failure. When the heart is unable to pump effectively, pressure can build up in the veins, causing fluid to leak into the abdominal cavity. This results in noticeable swelling and discomfort, often accompanied by a sense of fullness or bloating. Ascites can make it difficult to eat normally and may be mistaken for weight gain. Although it can have other causes, when combined with other symptoms, it could indicate heart failure. A medical evaluation is essential to determine the underlying cause and appropriate treatment.
