14 Silent Signs Your Kidneys May Be Struggling

3. Swelling and Edema

Swelling, also known as edema, in the hands, feet, ankles, or face can be a silent signal of kidney issues. This happens when the kidneys are unable to remove excess fluid and sodium from the body, leading to fluid retention. The swelling is often more noticeable in the morning and can become more pronounced as the day progresses. While edema can have various causes, its presence, especially when accompanied by other symptoms, should prompt a closer look at kidney function. Recognizing edema as a potential kidney issue can lead to early diagnosis and treatment, preventing further complications such as heart problems. Managing fluid intake and following a kidney-friendly diet can help alleviate symptoms and improve overall health.

4. High Blood Pressure

High blood pressure is both a cause and a consequence of kidney disease. The kidneys play a vital role in regulating blood pressure by controlling the volume of blood (by adjusting the amount of water excreted) and the levels of hormones involved in blood pressure regulation. When the kidneys are damaged, they struggle to maintain this balance, leading to hypertension. Conversely, high blood pressure can damage the blood vessels in the kidneys, exacerbating kidney disease. Monitoring blood pressure regularly and maintaining it within a healthy range is crucial for kidney health. Lifestyle changes, such as reducing salt intake and exercising regularly, can help manage blood pressure and protect kidney function.
